HOW TO CRACK, by +ORC, A TUTORIAL


Lesson 4 (2):Time protections, part 2
A little Micro$oft bashing :=)


[MS-WINPROJECT] [MS PUBLISHER 97] [MS-MONEY 94] [MS MONEY 97]


  

  (Hic sunt tabulae: Best viewed with good old Courier New 8)


     Well well well, my dear friends, it's April, the "opening"
month, when trees unfold and the womb of nature opens with young life...
about time we start with the REAL work, and what I mean is that we
begin damaging Microsoft interests... the real ones. I will therefore 
teach you here how to crack Microsoft's ubiquitous "trial version 
time protection".

     The typical Micro$oft's trial limit (of three months) is a
clever marketing approach per se: I'm speaking of the "trial" version
of their programs that you are supposed to use and enjoy for 90 days,
until a screen reminds you that you WILL not be able to use it any more, 
coz the 90 days are over, please pay. Note the clever touch of  90 (instead 
of 30) days: three months are more than enough to get you real hooked on a
program, especially huge monstrosities of the complexity of MS overbloated
applications... it's a much better period than the usual "30 days" 
flavour that we find around in common shareware.

     Since Micro$oft makes the bulk of its money from software
sold to corporate executives, senior sparer and assorted yuppies, it
suits us well to crack as first example of this lesson, Microsoft PROJECT,
one of those ridiculous "yuppie" programs that allow you to "plan"
and "schedule" an activity or a project of your "team"... as if we
were all time-slaves like those idiots... besides I may as well use this
crap to program the nice "activities" of my +HCU's cracking units :=)

     I'm therefore cracking here the 90 days trial version of
MSOFFICE WINDOWS PROJECT Version 4.1 of august 1995  which has the
protection hidden inside the monstrous WINPROJ.EXE (4.240.896 bytes of
overbloated bad programming). The error and protection messages dwell inside 
winproj.DLG (overbloated dialogues of 1.179.822 bytes).
     We'll begin with this somewhat "older" example of the ubiquitous 
"MS-trial" protection scheme (from 1995), since, as I have already told 
you elsewhere, the *history* and the *evolution* of protection schemes 
are powerful additional WEAPONS, that a cracker can use to defeat
more complex schemes that may not be so evident if you cannot recognise 
their "physiognomy" at the first glance (or if you do not yet "feel" them :=) 
We'll crack in this lesson a Microsoft program from 1994, another one from 
1995 (this first one) and two from 1997. I believe this should give you a 
wide enough palette of MS-protections, and that with this knowledge you 
should be able to crack every single piece of software Microsoft may throw 
at you in the next couple of years (at least :=)
     You'll see for instance that the "cmp eax,ecx" instruction
at the heart of some of these MS-schemes is a constant characteristic,
that you'll meet again and again, which differs from the typical "beggar off
on bad flag ax" setting that the shareware authors usually use.

A SMALL THEORETHICAL DIGRESSION
First of all, before entering the guts of MS-cracking, a small "theoretical" 
digression.
From a cracker's point of view, the new "trend" to give away full time 
limited versions of a software packages is extremely interesting:
once you defeat the time checking routines (... plural coz there may
be much more than one inside the same program) your work is done and
you'll immediately enjoy the full application. 
     The reason behind this trend (from password to time-trial)
is quite simple: password-serial number protections are useless on a Web
which abounds with free pirated serial number listings (I saw one with 54.000
different serial numbers-registration strings couples!) that anybody with
intelligence level "amoeba" can easily find. I do not like serial number
collectors: they do not teach anything, in my (admittely biased) opinion they
just steal... fact is anyway, that the mere existence of such huge
ready-made password listings has nuked any programmer's confidence in the
serial/string protection approach (whose cracking techniques I have explained
elsewhere in this tutorial), and this is the more true for "commercial"
(i.e. "non toy") applications. 
     You will find therefore, for big commercial application, the
"Cinderella" protections (you may use this app for 30 days) or
the "quiver" protections (you may use this app 30 times), or a combination of
these two kinds, or a combination of both kinds PLUS the registration
string/serial number protection method.
     One of the (minor) problems for us nice crackers is that
with this kind of protections we may have some surprises later on... i.e. you
crack your target and it works fine... well past the date it should have
been crippled upon, WHEN YOU SET this DATE INSIDE YOUR OS but -alas!- it stops
miserably working WHEN THE REAL TIME "of the world" has passed that cap...
this has to do with OTHER protections, checking randomly, for instance, the
date of some UNRELATED FILES on your hard disk.
     Obviously this does not concern us much... as soon as this
happen we crack this "second level" protection scheme too, happily drinking
another Martini-Wodka (use only Moskowskaja and add some Indian tonic
Schweppes and a zest of lemon if you want to taste something
that's really good) and forget the whole incident... but I had
to mention it right now because I honestly DO NOT KNOW YET if
some of the programs that I'll crack in these lessons do have or
not such additional protections, nor have I the time to feel if
there are other protections inside overbloated 5 million bytes
horrors once I have already found the first (and maybe only) one,
nor have I envy to wait 90 days just to see if something else
snaps... should it happen (which I DO NOT believe, seen how
primitive MS-protections look like) I'll then simply add the new
crack to this section, we'll see.
---------------------------------------------
Some elementary MUST KNOW when you crack time protections:
Date and Time stamps in the root directory (old flavour)
     The root directory (in DOS) is a simple table of 32-byte
entries, defining each file on the root directory. Bytes 0-7 have
the file name, 8-10 have the file extension, 11 hydes the
attribute flags, 12-21 are at times used for other protection
tricks, 22-23 have the *TIME* stamp, 24-25 have the *DATE* stamp,
26-27 the starting cluster number and 28-31 the file size.
     The date and time stamps can record any date from January
1, 1980 through December 31, 2099. The time stamp is accurate to
two seconds. The date and time stamps are each 2 byte values that
are recorded by using the following equations:
               DATE = DAY+64*MONTH+512*(YEAR-1980)
               TIME = SECONDS/2+32*MINUTES+2048*HOURS
     In the time entry, the hour occupies the first 5 bits, the
minutes the next 6, and the second the last 5. The seconds are
actually stored as the number of seconds divided by 2, so the
clock is accurate to 2 seconds. In the date entry, the year
(subtracted from 1980... that is 0x7bc) is stored in the first
7 bits, the month in the next 4 and the day in the last 5 bits.
How do we recover these values? Here the commonest tricks:
seconds   AND byte 22 with 11111; then multiply by 2
Minutes   AND byte 23 with 111; then shift left 3 and
          add byte 23 shifted right 5
Hours          Shift byte 23 right 3
Day       AND byte 24 with 11111
Month          AND byte 25 with 1, Multiply by 8 and 
          add byte 24 shifted right 5
Year      Add byte 25 to 1980 (0x7cb) and shift right 1
     I hope you have the intelligence to understand by yourself
why these methods work... the point is that as soon as you see
something like that going on in the code you are examining, you
will know that they are fiddling with date or time stamps (may
be necessary, for instance, in order to reset the date and time
stamps of an opened file without leaving any trace behind).

How does a programmer fetch the date? He uses the _dos_getdate
function.
The _dos_getdate function uses system call 0x2A to get the
current system date.  The date information is returned in a 
dosdate_t structure pointed to by date.
Synopsis:
#include [dos.h]
void _dos_getdate( struct dosdate_t *date );

struct dosdate_t {
        unsigned char day;      /* 1-31 */
        unsigned char month;    /* 1-12 */
        unsigned short year;    /* 1980-2099 */
        unsigned char dayofweek;/* 0-6 (0=Sunday) */
};

-------------------------------------------------------

AND NOW RUB YOUR HANDS: TO WORK!
     And now rub your hands: to work!   Fetch your copy of the
time limited version of  Winproj.exe (you'll find it on the
web... many magazines in Europe have published it on their cover
CD at the beginning of this year... The one I use here is taken
from a second-hand French magazine I found in Basel some time
ago: PCMAG n.108)
Well how do we proceed?
As usual: Let's dead list everything (but you could get pretty
quickly to the "hollow" point of your target through winice, is
a matter of aesthetic choice, I prefer dead listing because it
is more "relaxed" but you may use a combination of both
approaches or whatever you like most).
     First thing you notice is that the dead listing is HUGE:
more than 50 megabytes of text. You'll need a good wordprocessor
to handle that... Microsoft's last one, word version 7.0 does not
even accept such files, but look! Word 2 (the old version of
Word, 1992 vintage) does run them (almost) without problems (you
would not -obviously- have such problems under dos or linux).
It's quite ironic, I believe, that Word 7 cannot open such a
file, but on the contrary Word 2 ('92 version!) is capable of
doing it... this confirms what I always supposed: huge
overbloated programming is getting worse and worse... humanity
has probably already entered one of its many phases of decadence
:=)

LET'S SURPRISE THE PROTECTION SCHEME FROM BEHIND
We can get to the protection scheme of this target in many ways
(and there are yet many more... almost as many as you fancy).
Usually, to defeat these protections the traditional approach is
to set the OS date past the trial period, run the target,
individuate the nag screen as soon as it snaps, get the maximuml
information about it (comprised its pixel dimensions) and then
breakpoint it using some of these data) for instance (with
winice) bpx on MessageBox (MessageBoxA to be exact). Remember
that with Godot (Winice 3.0), you can use CONDITIONAL
EXPRESSIONS! Say that the hwnd command gave you 09017E as handle
for the nagscreen (this value will be different EVERY time you
run your target), then you can selective breakpoint on it with:
          :bpx MessageBoxA IF ((ESP->4) == 09017E)
since all Win32 applications pass parameters on the stack
enetering a function and  the first parameter has a positive
offset of 4 from the ESP register.
 Then you track back to the responsible code and so on and so
on... since the protectionists are aware of these obvious "weak"
points in their schemes, their "defences" will be all
concentrated on this "path" (encrypted date compares far away
from the messagebox call, bogus jumps, fake routines etcetera)...
they'll try to defer people reverse backtracing to the protection
scheme from the nag screen. 
     We will therefore hack our way to these protections sneaking
in from more hidden, less used and and less obvious doors, like
(in this example) GetLocalTime or (as we'll see later) through
the various "Write and read" file routines (i.e. the _open,
_lseek and _read routines that the protection schemes use to
fetch from the registry (or from somewhere else) the encrypted
date of installation. The point is to take our target's
protection schemes by surprise, from "behind" :=)
     OK: First of all... we have to do with a time protection,
duh, therefore GetLocalTime is a first bait we can jolly use,
let's see if we fish anything thattaway:

*GetLocalTime,(Kernel32-E2h) ;HERE!
------------------------------------------------
PARAMETERS inside Windows' FUNCTIONS
After this call the program must save the time parameters: for
those of you that do not know anything, the typedef structure is
the following one... (VERY IMPORTANT FOR TIME PROTECTIONS! Learn
it by heart! It's used in many other various FileTime routines
too):
------------------------------------------------
WORD wYear
WOED wMonth
WORD wDayOfWeek
WORD wDay
WORD wHour
WORD wMinute
WORD wSecond
WORD wMilliseconds
------------------------------------------------
Why did we seek GetLocalTime? Because  the protectionists have
to know somehow if the program run over the allowed time and,
while there are many other methods to do this, one of the most
simple is a check through good humble GetLocalTime... so we'll
begin from here, ready to check all other possibilities only if
we do not fish anything with this bait.

Examining the savings of the return values from this routine, as
with many other time routines, you'll find in your dead listing
something like this:

------------------------------------------------
CALL [KERNEL32!GetLocalTime]
mov  dx, [EBP-10] that's the year, will be something like
7CD=1997
mov  dl, [EBP-0E] the month... lower part of a register is enough
mov  al, [EBP-0C] that's the day of the week, ditto
mov  al, [EBP-0A] that's the day
mov  dl, [EBP-08] that's the hour
mov  al, [EBP-06] that's the minute
mov  dl, [EBP-04] that's the second
and if somebody would care, you would have had also
mov  dx, [EBP-02] that's the millisecond, but few time
protections care for that (which is stupid to say the least,
since so many ideas come immediately to the mind :=)
------------------------------------------------

     I said "something like" the above, but things could differ
a little coz the count [EBP-xx] could be flawed by pushes and
then you would have something like -say- the year in [EBP-34]
and, accordingly, the month in [EBP-32] et cetera... anyway the
SERIE will always be respected, therefore you could also crack
these protection in a completely different (and easy) way, that
good old +ORC will now let you glimpse... simply set a breakpoint
on a user routine (study this part of winice documentation
WELL... you'll be able to crack almost ANYTHING with your own
breakpoint routines)... say when the target loads for instance
7D5h on ax OR on dx (you will not know which of both registers
the protection scheme use).. then simply run the program with the
changed os date 2005 (which is 7D5h) and see what happens...
you'll breakpoint smack in the middle of the protection scheme
:=)... Why use 2005 instead of 1997? Easy: we wont use the
current year (7CD=1997) nor the next couple of years, because the
protectionists oft use other unrelated variables with those same
values (say current year of release and a couple year more) *on
purpose*, to block these very  attempts. But, as I said, we do
not need to use winice to crack this cram... bear with me and
see.
     Let's be more technical: you have reached a level where you
have the right to UNDERSTAND exactly how to access parameters
(i.e. the fixed values that MUST be passed to a function) and
local variables (i.e. the values that the protectionists have
decided to use, say in order to compare or manipilate) inside
windows calls:
-    If you set a breakpoint at the exact function address, for
example, :BPX GetFileTime, use ESP+(param#*4) to address
parameters, where param# is 1, 2, 3, or whichever parameter that
function calls... Since BOOL GetFileTime(HANDLE hFile, LPFILETIME
lpCreation, LPFILETIME lpLastAccess, LPFILETIME lpLastModified)
you'll easily know what is what.
-    If you set a breakpoint INSIDE a function body (after the
full prologue PUSH EBP, MOVE EBP,ESP, SUB ESP,size (locals) has
been executed)use EBP+(param#*4)+4 to address parameters.
-    Once the space for local variables is allocated on the
stack, the local variables can be addressed using a negative
offset from EBP. The first local variable is at EBP-4... with two
pointer local variables (typically dword sized) one will
therefore be at EBP-4 and the other will be at EBP-8.
Comprendes?
Enough... back to our calls to GetLocalTime... see how the
"centralised" call approach of windows helps us a lot... all the
calls of the program to this routine are here under our eyes...
look at the 13 CALL references, once more, (THIS IS IMPORTANT)
look at WHERE they come from:

A LITTLE ZEN: FEELING THE CALLS OF THE SEA
Ok, let's see which sectors of our target do actually call our
bait GetLocalTime... look at the call references above! Out of
13 calls, Sectors "024F" and "167F" and "223F" call it twice,
whereby Sectors 035A, 0648, 11A2, 1F9E, 204C, 2240 and 271A call
it only once.
This may not mean anything, of course, but hey! on the other hand
it could be very interesting... clearly we'll examine FIRST what
happens in these "time-intensive-calling" parts of the code:
Let's begin.

1)   "Sector 024F" calls GetLocalTime twice, why?

     Quite interesting... a flagging (that could be a green
light) and some parameters saved and compared within a holy
location... why does this "sector 024F" call? Is it just checking
against an holy location IF the time has changed enough to
justify the snapping of other routines? Or is it this the part
of the code that encrypts the date in the holy location
itself?... We could follow this path, and "freeze" the holy
location, or explore who calls this code snippets... this would
bring us to the protection scheme as well of course... but this
kind of work -MADE NOW- would not be methodologically correct... 
YOU SHOULD INDEED NEVER GO ASTRAY... KEEP YOUR CRACKING APPROACH
(as long as you do not get obvious signs that you found what you
were looking for), it's like landing a plane... keep the original
approach and DO NOT delve inside everything you happen to notice
that "might" be a treffer! Here we have something "biting" the
hook (our worm is GetLocalTime), but it's not yet time to pull
out our fishing line yet.. let's continue... We were
investigating all sections of our target's code which effectuate
at least a double call to GetLocalTime... let's continue! Let's
have a quick look to the other two "twin" occurrences of
GetLocalTime (167F and 223F) before delving inside any one of
them... maybe we will not need to delve at all. Remember, always
concentrate on ONE approach at a time: multa agendo nihil agens!

Here the second "twin calls" location area:
2)   "Sector" 167F calls GetLocalTime, why?

     Well, that's was it actually... we notice two consecutive
locations with 5Ah (90 decimal) there... as if they had written
"OUR TIME LIMIT IS HERE, PLEASE REMOVE AND USE FOR EVER AND
EVER". Maybe Micro$oft wants exactly this... I mean, they give
away their (bugged) web browser for free just in order to
bankrupt Netscape, why shouldnt they as well give every software
away for free (bad protecting it on time limits and spreading
everything on all cd-rom covers of the planet) until they have
bankrupted every concurrent and do effectively held every user
on the planet "pillado por los huevos"? 
     Maybe in cracking this protection scheme I'm only helping
Gates... the more people use its programs the more they will
spread... the more he will dominate the market... yet I could not
care less about Micro$oft's own stupid plans...  programming the
way they do, they will never be able to dominate a portion of
halfbacked potatoes in my humble opinion... therefore let's crack
this crap black and blue and let's hope Micro$oft loose a lot of
money thank us, yeah, that's life! Let's crack a lot of Micro$oft
software from now on! A white flower in our mouth, a computer not
far away, a cold determination in our fingers. Death to Gates!

*** Quick Crack for Micro$oft's Project 95, by +ORC, 04/1997***
search for the string
:05167FA6 66C745FE0100       mov [ebp-02], 0001 ;BAD FLAG****
and change it to:
:05167FA6 66C745FE0000       mov [ebp-02], 0000 ;always good
*** now find some stupid yuppies and give them this app ***

JUST A MOMENT (1)
Well, just a moment... go back to the code "snippets" above,
pupils... why did we not search for
:05168015 7C2B         jl 05168042        ;beggar off
in order to noop everything say with an inc/dec:
:05168015 40        inc eax   
:05168016 48        dec eax 
Why? 
Because it would NOT have worked... or, as a matter of fact, it
would have worked only in SOME cases... this is an example of a
"protectionists' bait", please examine the code. 
     You should -by now- know enough our art to be able to
understand by yourself why the crack at 5167FA6 works and the
crack at 5168015 (which is indeed part of the protection) will
not work... a hint for you: change months and YEARS of your os
as you experiment with this stuff. This answer is part of the
strainer of this lesson, therefore work on it and understand the
problem.
     And what about the remaining last "double call" location at
"223"? Did I not say we should keep steady on our approach before
delving inside?
     Yes and no: "quod satis est cui contingit, nihil amplius
optet" (Horatius, emailing his friends, as you can see you can
always find a proverb to demonstrate what you are saying, even
if you are contradicting yourself :=)
     But as soon as you SEE the protection there is NO POINT
(unless you really have to, in order to understand some weird
scheme thoroughly) to continue... the plane is landed, relax,
drink something.
     Anyway for such things there are no fixed rules... do
whatever you like and prefer, I personally think that the best
approach is a mixture of iron will and extreme flexibility.

JUST A MOMENT (2)
But wait, since they used the 5Ah byte... could not we have found
the protection just searching for 5Ah? 
     Yes, and indeed, we would have found the scheme around it
immediately... but that IS NOT the correct approach, since you
should NOT always presume that the protectionists behave REALLY
always that stupid (even if they almost always do :=)

JUST A MOMENT (3)
But wait, could we have not just winiced the working of the
program in order to backtrace as soon as the protection nag
screen snaps?
     Yes, and it would have worked... but why ruin your eyes on
screen in a closed and may be dusty room, getting cramps in your
shoulders that not even a good massage will blow away, when you
can crack much more relaxed, sitting quiet in a shadowy garden,
looking lazily (it's April! A beautiful month! Go outside! What
the hell are you doing inside a room?) at a couple of sheets of
paper, feeling the wind among the leaves above you, while a cool
Martini-Wodka fizzles in your hands? If you want to use the
"live" winice approach go ahead... I'll even tell you right now
a couple of things that can be useful in order to crack some
(other) protections: for Cinderellas schemes bpx MessageBox or
bpx GetLocalTime or bpx GetFileTime and look WHO gets the "time"
data a little before the nagscreen snaps... I did not check but
I'm sure that if you do it here, you'll have quite a lot of calls
along the program, whereby the "initializing" calls from our
"sector 24F" will snap at the beginning (and at the end) of the
target life and our protection call (the one we cracked the bad
flag of) i.e.: 

:05167F6A E808CFEBFF   call 05024E77 ;CALL GetLocalTime in KERNEL 

will happen JUST BEFORE the snap... so you can crack thatta way
too... these patterns are always the same.

**************** A little icy digression *****************
This is -after all- a tutorial, therefore for those of you that
do not know anything, here are some useful (and well known) older
winice little tricks and memory addresses discussions. Even if
I do prefer to use as much as possible my "dead listing" methods,
I realise that at times the help of winice is indispensable...
the little tricks below refer to Winice for windows 95 older copy
(before Godot, i.e. 3.0) and you may skip this section if you are
using winice 3.0. which has the IF feature for conditional
breakpoints, the WHAT command and much more. I strongly
reccommand using Winice 3.0. In order to learn how to use it
correctly your best approach is to find on the web the GOOD
documentation of Numega (it's in adobe acrobat's PDFformat) here
you have the names you'll need to find it (and NAMES are the MOST
important thing on the web):
     Si30cr.pdf     3.205.000 bytes    COMMAND REFERENCE
     Si30ug.pdf     1.038.000 bytes     USING SOFTICE
Last time I fetched them they were inside the zipped file
     Sice3doc.zip, 3.358.000 bytes
read these documents thoroughly.  Once you read them you (almost)
will not need my lessons any more. 
But some of the simple tricks below can be useful even with
Winice 3.0., and anyway I want ALL of the readers of this
tutorial to know their tools and to use them in the best way,
even those too lazy or too stupid to fetch the above mentioned
files... therefore, here you are... some (older) winice's MUST
know:

BPM DS:xxxxxxxx  W GT 1E
Breakpoint first time that the byte at location DS:xxxxxxxx has
a value written to it that's greater than 1Eh (30)
Useful qualifiers are EQ (equal) NE (not equal) GT (greater than)
LT (less than) and M (mask) this last one is pretty complicated
but allows powerful breakpointing for dongles cracking: after
having given your routine command "tss", begin your dongle
breakpointing using, for instance: 
BPIO 3F6 R EQ M 11XX xx00
This defines a byte break point on I/O port read, the first time
that I/O port 3F6 is read with ANY value that has the two high
order bits set to 1 and the two lower ones to zero, the other
bits can be any value. The same is valid for BPM (breakpoint on
memory write):
BPM CS:802A2D22 W EQ M 0xxx xxxx xxxx xxxx xx11
you dig it? The mask method is even better than the qualifier one
if you are NOT sure about which value the protection will load :=)

CSIP NOT &F000:0 &FFFF:0
Breakpoint only outside BIOS useful to limit breakpoint snapping
Remember that CSIP and BPM (READ/WRITE) can be very USEFUL to
slow down the execution of a windows program... if you use "heavy
breakpointing" in this way, setting a number of "useless" but
heavy breakpoints that winice will monitor, windows will crawl
(even on a Pentium 200) and you'll be able to breakpoint MANUALLY
exactly at the point where a protection snaps... I still prefer
the "dead listing" method of cracking personally, though.

BPINT 21 AH=0F
Breakpoint on openfile (funny how many INT 21 are execited under
windoze)
(old style, with Winice 3 it's BPINT 21 IF EAX=0F)
BPINT 21 AH=2A
Breakpoint on GetDate 
(old style, with Winice 3 it's BPINT 21 IF EAX==2A)

When we are still at it, remember that in 32bit mode there are
only TWO selectors (when you search the whole memory for
instance):
28:0 and 4 virtual gigabytes of CODE
30:0 and 4 virtual gigabytes of DATA and STACK

We saw (cracking DOS) how to get from virtual address to physical
address in 8086 style segment:offset code: multiply the segment
by 16 and then add the offset. In a "protected mode" selector
it's different: linear address is calculated by adding the offset
TO THE BASE ADDRESS FOUND IN THE GDT (or LDT, local descriptor
table is used if bit TWO of the selector is a 1, global DT is
used otherwise... GDT and LDT are "lookup" tables used to
calculate addresses).
At times you must understand a little the physical addresses
structure in order to crack effectively:
00000000 - 000FFFFF Current Virtual Machine (Windows and Windows
Programs)
00400000 - 7FFFFFFF Physical memory (contiguous)
80000000 - 803FFFFF      Windows' VxDs
80500000 - 80FFFFFF Windows programs
81000000 - FFFFFFFF DOS VMs
...use the commands "page" and "addr" and have a look around. The
command addr is also very useful to understand in which context
you are when winice pops up.
Remember that each 32 bit task is given the address space from
400000 to 7FFFFFFF, which is called an "address context". This
virtual address space is reserved for 32 bits applications and
private DLLs

And now two MUST KNOW winice commands that will spare you a lot
of wasted time when you delve inside the huge windows codebulks
we have to peruse:

P RET (that's F12 most of the time)
steps out of the current procedure, may take ages if it's very
large
that's step until return

G @SS:ESP (that's F11 most of the time)
throws you at the caller of the procedure you bpxed on
(bpx GetLocalTime and execute F11 (or write G @SS:ESP) as soon
as winice pops up and you'll see what I mean)

A couple of watches like *ds:esi (and ds:esi) and a dex 1 ss:esp
in your ini setting of winice would be a good idea too IMO.

This said, Winice 3.0 allows POWERFUL breakpointin, like for instance:
bpx ntoskrnl!ExAllocatePoolWithTag IF (esp->c == 1) DO "data1;dd eax" 
(I will explain all this more thoroughly in the lessons about Windows NT)
**********************************************
Back to our time protections cracking (and Micro$oft bashing :=).

     Once more... there are THOUSAND different ways to crack
these applications, and this GetLocalTime "fishing" is only ONE
of them... I will teach you -of course- ALL the methods I believe
are MOST effective... you must be enough crack-able by now to
know when, applying these techniques to OTHER programs (hopefully
Micro$oft ones) you'll have to use slightly or substantially
different approaches... non semper Saturnalia erunt, as you'll
see.

Are these protections always so easy to defeat?
No and yes, may be no... yet there are far more complex schemes.
But time checking from a CD-ROM code is the ultimate doom of the
protectionists... you see: the problem for them is the following:
They are protecting using a "write only once" media (a CD-ROM)...
therefore every time you put the cd-rom in your driver you are
re-installing a perfect "virgin" copy of the protected program...
there is no way a recursive message can be placed INSIDE the
code, telling it to never execute again... I remeber older nasty
"quiver" protections in dos... after the 20ntieth installation
the program formatted as bad a sound sector of the diskette...
that was clever! But that's impossible on a read only media,
therefore let's see... where can they keep track of the
eventuality that you used it before?
1)   Inside the intricacies of Windows register, this most
obscure fat abomination (should I write a scary computer fiction
film, I would imagine a windows register growing fatter and
fatter, week after week, and then suddenly grabbing the user
through the a:\ drive in order to eat him :=)
2)   Inside an apparently unrelated file or *.dll that gets
"lost" inside the garbage subdirectories c:\windows or
c:\windows\system (by the way, that's exactly the same technique
you should use in order to protect your files at work from
administrator's prying eyes... throw every application inside
windows subdirs and give them funny names, like a6JJJK.EXE... no
administrator on this earth (and no censorship corporate
patrolling software) will come to the idea that that is your
beloved chess program :=).
3)   Inside small parts of the BOOT sector of your harddisk that
can safely be used for this kind of tricks without altering the
booting (this is a trick the protectionists have learnt from our
fellows viri-writers... see how even the bad ones have a teaching
function in this funny virtual world. Once more virus code
studying is VERY important in order to crack well. 
Alas for the protectionists! All these tricks are pretty easy to
defeat too, and I will show you HOW to do it :=)

For a start here is HOW easily you would have checked your boot
sector with an old DOS system...
1)   Run debug (or, better, symdeb)
2)   -L 100 2 0 1 
(that's Load into memory address Ox100 from drive C (that's
number 2... 0 is A, 1 is B and 2 is C, duh, starting from sector
0 for 1 sector whatever you find there. Here you have the boot
sector of the PC I'm writing on:
-L 100 2 0 1
-d 100 L 200

[MICROSOFT PUBLISHER 1997]
Time to bash Microsoft once more... how nice! Let's have a
(quick) look at Microsoft Publisher 1997, another "60 days" trial
version protection from Microsoft (60 days, because the DTP
market moves so quickly that they cannot allow to let it loose
for three months)... I'll show you where the protection is, how
it snaps and how to crack it... I got my copy from one of the
MANY magazines that published the 60 days demo version in April
1997... you should be able to find this one everywhere... here
are the relevant data:
 
MSPUB.EXE  2.476.304  19/04/97  19:19  <--- da target
MSPUB.ALF 34.054.330  17/04/97  20:18  <--- da dead listing
MSPUB.DED  2.476.304  19/04/97  19:19  <--- da copy you need

You should always do a copy of the original target BEFORE
beginning your work on it, you'l need it a lot when you time
deprotect.

To crack this target we'll use a slightly different approach...
let's call this technique "hit and see"... it's one of the most
obvious approaches, and I surely have not invented it...
everybody knows it: you run the program, you let the time
protection snap, you look at the "hardwired" hex differences
inside the body of the target (the "non functioning" copy will
slightly differ from the "functioning" one) and you "reverse
engineer" your dead listing back to the protection scheme that
snapped the differences... pretty easy, isnt'it?

-------- digression: words inside targets ---------------------
If you are interested in another, COMPLETELY DIFFERENT cracking
door, here are the relevant messages [expir] inside our target...
I used  SR32exe to fetch them (a very nice fetcher, thanks
fravia! :=), which  is much better than my own old C scripts :=(
As a small "extra" for this lesson, crack the protection out of
this fetcher, a program that I'm sure you'll find VERY useful (I
did):

As I said... there are MANY doors you may trespass to crack this
target... let's continue with the simplest one in my opinion: 

1)   Let's run it... it runs, how nice!
2)   Let's move the OS date... say four months ahead. 
     It does not run anymore, this is sad! 
3)   WHAT HAS CHANGED IN THE FILE? That's the point my reader...
Let's compare the two files... the original and the copy after
the fatidic message "trial time is out, won't work any more", bye
sucker:*

FC /b mspub.ded mspub.exe 

(that's the DOS command FileCompare that you are giving, duh)

And this is the result you'll get:
          "Comparing files mspub.ded and mspub.exe"
          "000F3703: 75 EB"
          "000F370C: 75 EB"

MMMM! That's interesting! And what do we have there? Let's have
a look at our (huge) dead listing (do not forget: 2560 (256*10)
bytes difference between REAL AND Wdasm addressing... you just
add A00h to the DOS addresses to get your bearings inside the
dead listing files... F3703+A00= F4103... F370C+A00=F410C):

:004F4135 C20400           ret 0004

All this means for us only one thing... location [005C22D0]
decides a lot. But wait, let's see... What did  these assholes
do? They "patched" their own program in order to protect it...
how funny... time is out, so jmp anyway (instead of jump on not
equal) to the evil routines... they know that now we would like
to know WHO calls here... and there are (therefore, as
dissuasion) hundert of procedures calling this cram... no point
in checking all of them... you would sink in a sea of calls...
what will we do? Where is the real and only one PROTECTION call
to 4F40FC among this bunch of useless calls? We have only ONE way
to find it out without losing time... Let's zen a little... you
have read this lesson from the beginning... now STOP and think...
i.e. use your brain (supposed you have one): do not read any more
what follow: STOP NOW and answer this question BEFORE
proceeding... really... you are here to learn, NOT TO COPY
METHODS THAT OTHERS HAVE FOUND... once more... We know that
somebody modified this cram... but HOW DO WE GET BACK (how do we
reverse the flow) TO THE CORRECT CALLING ROUTINE AMONG HUNDERT
OF THEM calling here?
Ok, you did stop and think... you may go on reading (if you did
not... be ashamed... cracking is like watching a beautyful
picture... you must think a lot, else your watching is useless).
OK: We used the GetLocalTime routine as a bait inside my first
example... can we apply it here? Let's search for it... HEY! They
do not use it at all, there is NO GetLocalTime in this
application... how the hel do they know which time is it?
Let's search for "time", my friends... here the locations:

Line 1871 -  Addr:102387D0 hint(0423) Name: local[time]

     Ok, that's more than enough, thankyou... let's begin from
the beginning... what about a little GetFileTime pinpointing to
start with? Where are the GetFileTime routines inside our target?

:004CBC11 FF1594005D00   Call dword ptr [005D0094]
;KERNEL32.GetFileTime
:004CBD3A FF1594005D00   Call dword ptr [005D0094]
;KERNEL32.GetFileTime

Only TWO? Most rewarding... and where is the triggering call to
the first one (probably to both of them)?
Have a look at the dead listing of our target... these cracks are
so simple that I wonder at times why the hell they insist...
either they shoudl learn HOW TO PROTECT PROPERLY the shit they
program, or they should give it for free to everybody (like I'm
doing now... hope that EVERY student and every poor chap in
Africa and Asia will use Micro$oft publisher for free without
ever giving them a cent... this is european cracking at his best!
And besides, that's the minimum we owe the poor slaves that do
sweat and work hard in order to pay for our barbecues :=)...
this is the synthesis of the dead listing:

OK, that's enough dead listing for now... we know now that the
REAL protection may call :004CBA50 (the beginning of the huge
code snippet above with GetFileTime and other file opening and
closing goodies)... and wdasm gives us the caller (only one...
THE TARGET!... don't you feel it?)

:004C8843   ;This is the call that triggers everything
          ;I told you: DO NOT FORGET IT

:...                          ...and the rest of the huge snippet

LET'S CRACK MICROSOFT'S MONEY 97 and 95 NOW
Let's finish this lesson with another sound hit at Micro$oft.
This is the main part of the strainer to next year's +HCU, please
solve it (it's MUCH more easy than last year's strainer).
I'm cracking here Microsoft MONEY 97, 90 days trial version I
found on the cd-cover of a review called PC-PRO, issue 31, MAY
1997 (but I bought it in transit at Heathrow airport for three
pounds at the beginning of April and not in May, as usual in this
awful commerce oriented society even minutiae like the dates of
the issues of magazines are completely false :=(
This is another kind of program I personally would not touch with
a pole, nor would I use it, even if somebody would pay me for
it... but I know that a lotta suckers buy  these ridiculous
applications greedly... such kind of customers do pay a lot of
money to Micro$oft... and to the banks, and to the various
asinine "investor advisors", and to all the awful commercial
people that has given us this grey world of unhappiness, and
inequality, where only irrelevance and bad taste are valued,
where knowledge is "allowed" only and only if it helps them to
make more money (not happiness)... where poetry and feelings are
considered useless and obsolete by the "market forces"... My, how
I hate cheerfully this whole bunch of "market operators"! How I
hope that the people they have enslaved will one day hang the
whole lot of them, pinning the TV-news moderators to the
doors of the TV-studios by their tongue as a good collateral
measure... (the sooner this happens the better, give it a move
please, I would like to take some nice photos of the hanging
bodies),... ok, enough, let's crack first of all the programs
used by this outrageous people, hoping that my crackings will
spread enough to diminish Gates' cashflow a little...  a pebble
of sand is nothing less than a pebble of sand, after all, let's
never forget it :=)

Let's see what happens here... once more with GetLocalTime? Let's
see... here you have three calling "points" for GetLocalTime:
at 45804D, at 46A308 and at 5DA056, let's call them 45, 46 and
5D. Since the one at 46 is referenced by not less than 80 calls,
we will  deem it more important than the first one at 45 (three
calls) and the third one at 5D (two calls).... but wait...

WAIT, HISTORY IS IMPORTANT
     But wait...may be we should delve a little deeper in
Micro$oft's protection strategies, may be you should  have FIRST
a look at an OLDER copy of Micro$oft's Money... say version 
3.00p of February 1994... the file you have to crack is here
MNYDEMO.EXE, length 1.173.184 bytes, from 8/2/1994... I found it
on a old cd-rom: PCHOME n.8 from June 1994, as usual, quite a lot
of magazines will have had the "privilege" of burning this trial
version on their CD-ROMs during that summer... you should be able
to find a copy of it on the Web too, if you happen to know how
to search and, what's even more important, WHERE to search... as
I said elsewhere, on the Web you can find almost everything...
provided you already know where it is :=) 

THE STRAINER... FIRST OF ALL YOU'LL HAVE TO FIND IT!
     Anyway, since this lesson is intended as a "strainer" for
next years +HCU, a part of your duty is TO FIND the targets we
have to crack... this will be easy for MS MONEY 97, but (I hope)
not so easy for MS MONEY from 1994... believe me, this searching
is  a very important art... you may be just lucky, or already
have (like me) a huge collection of many CD-ROM that appeared on
magazines covers and that you bought at discount prices... or you
may have to beg or implore or exchange programs with some old guy
from New Zealand or a weird wannaby warez dude from Corea, which
happens to have the copy you are interested in... you may have
to examine old usenet discussion groups, to peruse old
PC-magazines... to delve inside a lot of useless pages...
searching for your nugget. But you'll gain a lot of knowledges
in this process...  ignorantia est carentia scientiae debitae.

OLD VERSION, SAME LIMITATIONS
     The "trial" old demo of MS-Money 94 has an analogous
protection scheme to  the very recent MONEY '97 trial version?
Please check... if it is so, that would be VERY important for
us... history and evolution of  a targets' protections IS  INDEED
very important. If you'll delve inside cracking as an art, as I
would like you to, you'll see that patterns and trends play (like
in  real life) a tremendous unproportionated role... protections
mirror our society (at times I believe that everything does, but
me): real knowledge and innovation plays almost no role, stupid
"trends" and repetitions of the same boring schemes do actually
make the 99% of the "reality". 
     In the meantime life keep worsening for the stupid slaves,
more and more useless stinking cars are polluting our cities and
the "new" programs we buy are slower  and by far not as good and
powerful as the old DOS programs of 1990... a proof? For the dead
listing of this target you'll NOT be able to use Word 7.0 ("file
is too huge"), but you'll still be able to use Word 2.0 from
1994... funny, isn't it?
     This old "trial" demo of MS-Money has THREE levels of
protection:
1)   The system date in your computer must be 1994 or 1995
2)   There is a Cinderella 60 days limit (Micro$oft was not yet
a "90 days" enterprise... we are watching here the BIRTH of this
MS-protection scheme :=) 
3)   Transactions (i.e. fields of this database) can only be
entered within a 60-days period (this is at the same part the
"tricky" part of this crack and a key to the crack :=)

HOW DO YOU BEGIN?
I'm writing this to teach you MANY cracking techniques, let's
pack this target from another direction, let's forget winice for
a while and use a bit of "dead listing", a program like winsight
and some of the brain we are supposed to have:

1)   Have a look at the messages i.e.:
 install our target...
run it as it should, changing the OS date to 1994
change OS date past the 60 days limit
look at the message ("The 60-days limit of this working model..."
2)   Fire Borland's Winsight (I'm using here version 1.30 from
an old cracked Delphi, but you'll find hundred of them on the
web) It will describe you EXACTLY the nagwindow you have on your
screen:
Popup 0610 {#32770:Dialog} mnydemo.exe (144,183)-(523,345)"Notice of Expiration"
You may even get details on this Popup 610, if you feel like it.
4)   You have the NAME (very important). Search it inside the
dead listing (you have previously made with WCB or with wdasm)
of MNYDEMO.EXE, you'll get the following:

Name: 
DialogID_0494, # of Controls=004, Caption:"Notice of Expiration"
001 - ControlID:02CE, Control Class:"" Control Text:"The 60-day
limit of this working model has expired." 

See what's important? ID_0494... that's important.

5) Now search ID_0494 in your dead listing... you'll find THREE
occurrences (i.e. they call three time the 60-days limit) let's
examine them (with context):
Block 6 at 263:
6.263 is called "cascade" (switch) from the beginning of block 6:

       no parent or error)

Ok, for block 6 what should we say?  Can we start our crack from
here?

Let's have a look at the next block:
Block 8 at 17D2:

:0008.17E5 9A34019911             call 000.0134 ;call KERNEL.MAKEPROCINSTANCE

  that's the check for all open windows (Useless with 32 bit)

And, please, what do we have at 28.154C?

A jump below followed by a switch tree... is it interesting for
us? You'll answer!
Finally, let's have a look at the THIRD and last occurrence of 
our "Notice of expirations" at block 52 at 2465:

Well, I think this is enough:
The crack for it is pretty obvious, is it?

Let's start with a simple substitution:
instead of
:0008.17D0 7246            jb 1818
let's have
:0008.17D0 55              push bp
:0008.17D0 5D              pop bp
(nooping it)

That's it, folk!...  but, wait... all this DOES NOT work
correctly... did I forgot something?
THAT's the Strainer! Solve it (you have time until SEPTEMBER 1997).

THE STRAINER: SOLVE IT!

You want to be a +HCUker? SOLVE the crack for MS-Money (old
version and new version), I want to get from you (directly to
na526164@anon.penet.fi if it still works or else through channel
you have to find yourself)
1)   The complete and WELL described crack to MSMONEY version 3 (1994)
     (60 days trial protection)
2)   The complete and WELL described crack to MSMONEY 97 (1997)
     (90 days trial protection)
3)   The reason for the crack I used for Winproject instead of
nooping the alternative location... which would have seen more
obvious at first glance.

     I would like you (since these cracks are alltogether much
more easy than the Instant access strainer we used last year) to
DELVE DEEP inside the date-encryption routines of these programs,
explaining them perfectly.
     Please use a language that newbyes can easily follow... I
do not intend to work in order to re-explain once more things you
should have explained well in the first time.
     Best protection busters (and best approaches) will enter the
+HCU. Lamers and people that have copied from other will be left
out.
     +HCU 1998 will begin on 1 Januar 1998. The above solutions
must be sent to me BEFORE september 1997. Should anon.penet die,
I'll reopen another anonymous channel end August.

Well, that's it for this lesson, reader. Not all lessons of my
tutorial are or will be on the Web.
     You'll obtain the missing lessons IF AND ONLY IF you mail
me back (via anon.penet.fi) with some tricks of the trade I may
not know that YOU discovered. Mostly I'll actually know them
already, but if they are really new you'll be given full credit,
and even if they are not, should I judge that you "rediscovered"
them with your work, or that you actually did good work on them,
I'll send you the remaining lessons nevertheless. Your
suggestions and critics on the whole crap I wrote are also
welcomed. Do not annoy me with requests for warez, everything is
on the Web, learn how to search, for Hiawatha sake.

     "If you give a man a crack he'll be hungry again
     tomorrow, but if you teach him how to crack, he'll
     never be hungry again"
