; <20>< Win32.Plexar ><3E>
; Designed by LiteSys in Venezuela, South America
;
; PE/DOC/XLS/OUTLOOK Multithreaded Polymorphic Direct Action infector.
;
; Welcome to Plexar, my latest code.
;
; It infects PE files by incrementing the last section, I don't overwrite
; .reloc section, it's preferible to let it alone. In fact, this virus
; avoids infecting some AV or Win32 files that should never be infected.
; This is done by CRC32 comparation.
;
; Infects Word and Excel documents by dropping (thru VBScript) a macro
; module-infectant virus in the normal template and personal.xls that is
; capable of dropping an infected PE file to the Windows directory and then
; running it.
;
; Distributes through Electronic Mail by dropping a VBS worm capable of
; sending infected droppers to every email address in the Outlook address
; book. Sorry but I didn't have any time to code a decent MAPI worm =(.
;
; The Poly engine is another lame table-driven engine written by me =), no
; anti-aver intentions were the reason to write that poly engine, just to
; conceal the code a little. So I think it doesn't desire an explanation
; because the garbage is very lame.
;
; It runs the different routines (word infection, vbs worm, direct action)
; in different threads. As I always said, I don't optimize my code too much.
;
; The payload is very funny and if you're from Venezuela I hope you
; appreciate it. Consists in dropping a simple com file that displays
; some silly stuff in spanish, it runs on autoexec.bat but won't display
; the message until the following rule is complied (this is a very
; kewl idea I learnt from Byway ;D):
;
; If Month <= 7: Day = Month^2 / 3 + 4
; If Month >= 8: Day = Month^2 / 5 - 4
;
; So the payload will run on every month (as a coincidence, the formula
; pointed to December 24th :P). It's not destructive so don't blame me.
;
; This virus has lots of bugs, i've corrected many but still there are a
; lot. It was tested under Win95 (4.10.1111), Win98 (4.10.1998), WinME and
; WinNT (4.0/SP4), the virus worked perfectly under those versions. I don't
; know about Win98 SE and Win2K, since I don't have them installed, I have
; the CDs here but i'm a lazy ass and my HD space is totally phuken.
;
; Virus Size = 12kb. Code not commented. Nor even AVP or Norton (with
; their "high heuristic" bloodhound shit) flagged the infected PE baits,
; except from Norton, which flagged the VBS worm.
;
; If you need to contact me you can use both mail addresses: litesys@monte.as
; or liteno2@softhome.net. Rembember, for decent stuff.
;
; Patria o Muerte: Venceremos.
