Dongle protection reversing (HASP) - Pinit dongle testing
(Encyclopaedia Universalis: the French reference)
by The+Chineese
(29 November 1997)
Courtesy of fravia's page
of reverse engineering
Well, another interesting dongle essay... pinit tests and dongle verifications
programmed in visual basic... gosh! There is may be a little too much code in here, but
people that have to tackle dongles will appreciate this essay a lot.
Let hundred
archive sites blossom!Another important
lesson (once more): As +ORC always teached, to know the HISTORY OF SOFTWARE is of paramount importance for
our cracking endeavours... As many of you will probably know, in every decent
virus group there is
at least one guy that has the title (and function) of "keeper of the virii"... a very useful
'sofware' sort of archivist, that collects and keeps available past (rare) specimens for all
interested researchers...
Crackers should
in my opinion begin to find (or nominate :-) some 'keepers of the old targets'... people who have
somewhere
very stable
shell space and could gather, maintain, explain, update and keep
available for everybody (of course uncracked :-) for instance, the WHOLE collection
of all PAST versions of Hexedit.
Let hundred archive sites blossom... I bet, moreover, that
such "specialized" archive-sites would have MANY more visitors (and for ever!) that many
poor cracking/hacking "banal" pages have at the moment!
This said
here you have The+Chineese cracking 'the evolution' of a French dongle protected encyclopedia...
head his words: you don't need a dongle to crack a dongle protection! This is true, remember,
for MOST DONGLE PROTECTIONS! Yes, my readers, I actually don't know why +ORC speaks in his
tut of hardware dongle cracking... in my own experience I have seen that you
can crack (almost) all dongles without hardware... and without even having put your
hands on the dongle itself! (So much for "heavy hardware protection
enjoy!
DONGLE PROTECTION (HASP)
ENCYCLOPAEDIA UNIVERSALIS
(the french Reference of Encyclopaedia)
ENCYCLOPAEDIA UNIVERSALIS SAGA
---------------------------------
Let's study the History of they Protection Scheme.
(as +ORC wrote it's important to study the History of
software Protection scheme)
look at http://www.encyclopaedia-universalis.fr
there is no downloadable Version but some Friend told
me that for the UNIVERSALIS Version 3 (1997) the latest one,
they (Universalis Crew) make a "Marketing" offer:
they send you the Complete Version 3 (with the Dongle of Course)
and you try it for 15 Days.
If your are not satisfied you send them back the Dongle and CD-Rom !
(and don't forget to thanks them with a 'Merci Beaucoup')
UNIVERSALIS 1 (1995):
------------------------
(16 bit writen in VBasic and BC++ (VBRUN300.dll and use Hasp.386))
dongle Type: i don't know (HASP! BUT WHICH ONE ??)
the target : EU.DLL 103.424 Bits (16Bit writen in BC++)
the Weakness:
after launching the proggy
(cdu.exe (32000 Color) or cdul.exe (256 colors)
there is a messagebox (16bit) who tell you in a bad french
"Aucun serveur protection actif n'a pu etre trouve (IPX ou NETBIOS)"
the Difficulties:
the EU.DLL is moveable, it's not easy to put a breakpoint with S-ice
EU.DLL is called by VBRUN300.DLL
UNIVERSALIS 2 (1996):( addons : ATLAS , PHONETISEUR)
------------------------------------------------------
(16 bit writen in VBasic (VBRUN300.dll and use Hasp.vxd))
dongle Type : MEMOHASP 1 ((according the dongle it-self)
the target : EU.DLL 120.784 Bits (16bt writen in BC++)
the Weakness:
same as above with the error message: "La clé de protection est absente"
the Difficulties:
same a above and a Checksum on EU.DLL
and some other call to Error Routine
UNIVERSALIS 3 (1997): ( addons : ATLAS , PHONETISEUR, DICTIONNARY, PAINTING )
------------------------------------------------------------------------------
(pseudo 32bit bit writen in VBasic (VBRUN300.dll and use Hasp.vxd))
Dongle Type: HASP 3 (according the dongle it-self)
the target : EU.DLL 127.344 Bits (16bt writen in C++)
the Weakness: no more Messagebox (but we use kernel!openfile)
the Difficulties:
a little bit more difficult
cause in the previous version the proggy starts the interface an
via a messagebox tell us "erreur pas de dongle".
in this one it does nothing it just Crash .
( allways a Checksum on EU.DLL and some other call to Error Routine )
TOOLS:
-------------
-S-ice 3.21
-WDasm8.9 (or previous)
-Hworks32 (any Editor)
and ultraedit32 for writing this essay :-)
INTRODUCTION
---------------
as Fravia+ said Dongle protection is
the "bête noire" of all Crackers,
and i thanx him for the DONGLE PROJECT and Zafernon for his works on Hasp.
but This one is not so difficult !.
A) let's study UNIVERSALIS VERSION 1 (95):
-------------------------------------------
in the Universalis Case using bpio (-h) 378 (379/379 etc) doesnt Works
and if we look at the dea-listing of EU.DLL
we found suspicious function like PINIT, PTEST etc..

as you can see this dll is moveable so it's hard to bpx at this Function !
so it's easier to use bpx messagebox
then fire cdul.exe(or cdu.exe) and you 'll break at messagebox and after two F12 in Sice
you stand here (at 0014.39d ) in PTEST (in fact PTEST is called very often (in Background)
and is TESTING if you have not removed the Dongle )

So if we make the change the code at 0014.35e and 0014.36e we defeat the Dongle Test
But we notice that if there is no more messagebox warning us about "pas de Dongle"
the proggy doesnt works at all cause the search index is not initialised.
in fact We forgot the PINIT function ! (The PINIT function Test the Dongle
and if there is one it make the search index initialisation)
so bpx messagebox
fire the proggy (cdu.exe or cdul.exe)
and when you break into Messagox do 3 F12
and you stand in VBRUN300.DLL in a call Far Routine
in fact you are in the routine who call all the PINIT, PTEST function of EU.DLL
see this piece of code
in VBRUN300.DLL
2277:6488 call Far es:[bx] <-- Now we can bpx at this adress
call 6522
call 67D1
mov cl,FF
Add di,di
jmp cs:[DI+6498]
.
.
.
and in here we bpx 2277:6488 at the call Far es:[bx]
we quit universalis
and one more time we launch cdu.exe
and we Break into vbrun300.dll at 2277:6488
do F8
and we are at the begining of the PINIT function in EU.DLL

What we know ?:
-that the PINIT is call by VBUN300.DLL and if there is a dongle
it initialise the Search Index.
-that the PTEST is called very often and test
if we not remove the dongle (if we have one)
-and a messagebox warn us if we are Bad guys.
-and there is a checksum this Version 2
(i dont explain here the checksum scheme because it's not the more
important thing , we have just to remember how to recognize a checksum
i.e looking for _lread, _lseek, openfile etc...)
so looking at the PINIT function we found a
call for openfile and getmodulefilename
look at this

C) Let's work on UNIVERSALIS Version 3 (1997)
----------------------------------------------
The Protection scheme is Quasi The same as Version 2
the only change is that when launching cdu.exe (or cdul.exe)
nothing happens (if no dongle is on printer port)
it just crash. So if we ignore all the Precedent Work
The Messagebox trick doesn Works !
So we can try bpx kernel!openfile ,cause we know that it's make
a checksum with EU.DLL
So do BPX KERNEL!OPENFILE and after some F5 in s-ice
we are in EU.DLL at PINIT function .
(and the Work is the same as Version 2)

RESUME
--------------------
Encyclopaedia Universalis is really a good and complete
French Encyclopaedia.
But The Protection Scheme is not really good (not at all)!
Even if it use MEMOHASP Dongle ,its not a hard Crack,
cause u dont need The Dongle To crack it at 100%!
