³ I-Worm.Energy ³
ÀÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÙ
ÚÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ¿
³ by Benny/29A ³
ÀÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÙ
hey all...
ÄÄÄÄÄÄÄÄÄÄÄ
it was one b0ring sunday, when I decided to code some small and kewl virus...
I was tired from coding large projectz (HIV, XTC)... I wanted to code one
worm with some nice ideaz, like the Win2k.Stream.
and here it is. after some meditationz, full of experiencez from psychedelics
I decided to call this worm "Energy"... it is very small worm, spreading via
RAR filez. it can parse all processes, hook there MAPISendMail API procedure
and infect all attached RAR filez in a message by dropping itself to there.
very similar technique of the process'es address space manipulationz is
described in my article "Multi-process residency" and Win32.HIV virus. surely
it can't work on Win95/98 systemz. it worx on Windows 2000 OS, and (perhaps)
also on earlier versionz of Windows NT - but I don't know, I haven't tested it.
it can stay resident in memory as a service, by standard API callz, valid only
in NT systemz. while infecting the RAR archivez it addz itself to there under
the "SETUP.EXE" filename, containing also the standard setup icon. I tried to
optimize the source a bit... I know the worm is not super-small, but I it is
resident heavilly armoured very effective tiny mail-spreading worm.
the scheme of execution:
ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ
after execution:
- anti-* stuff
- if initialized by SCM, run as a service process
- copy worm to system directory as "ENERGY.EXE"
- register worm as service process and run it everytime the OS will start
- enum processes, find MAPI32.dll there and hook MAPSendMail (using many
trics)
- wait one minute and again
hook_procedure:
- parse embedded filez and search for RAR filez.
- infect them by worm file: SETUP.EXE, mark as read-only (already-infected
mark).
the worm is encrypted/compressed by "tElock, version 0.51", one very nice
utility for armouring executable filez. this protector containz many nice
anti-* featurez. that's why I decided to use it. and also becoz I think guyz at
AVP can't handle this one.
it is possible that worm containz some bugz. yeah, but I don't care... I'm glad
I was able to finish it in 2 dayz and that it was not b0ring. I had a fun.
If you would like to consult anything with me, feel free to contact me...

;;; http://www.antivirus.com/vinfo/virusencyclo/default5.asp?VName=WORM_FBOUND.B&VSect=T
;;; Details:
;;;The details of the email this worm arrives with may be as follows:
;;;
;;;To: <recipient>
;;;Subject: <"Important" or random Japanese text(applicable on Japanese supported platforms)>
;;;Message Body: <blank>
;;;Attachment: patch.exe
;;;
;;;It uses its own SMTP engine and uses the following registry key to retrieve the default SMTP server of the infected system:
;;;HKEY_CURRENT_USER\Software\Microsoft\
;;;Internet Account Manager\Accounts\00000001
;;;
;;;It uses the following registry key to retrieve email addresses from the infected user's Windows Address Book (WAB):
;;;HKEY_CURRENT_USER\Software\Microsoft\WAB\
;;;WAB4Wab File Name = “<pathname of WAB file>”
;;;
;;;The email arrives with the attachment PATCH.EXE. If the email address of its target ;;;user ends with the extension .jp, the worm randomly selects a phrase, from a list of 17 possible Japanese phrases below, and uses one as the subject of the email:
;;;
;;;
;;;The English translation for the above Japanese text are as follows:
;;;Re: the issue that you mentioned
;;;Re: important
;;;Re: long time no see
;;;Re: top secret
;;;Re: Hello
;;;Re: important information
;;;Re: data
;;;the issue that you mentioned
;;;important
;;;long time no see
;;;top secret
;;;hello
;;;important information
;;;data
;;;frog
;;;shit
;;;shit
;;;
;;;Otherwise, it uses the subject “Important."
;;;
;;;This non-destructive worm does not drop files or create any registry entries. Its propagation depends on the execution of the file attachment in the email.
;;;
;;;The following text strings are found in the worm body:
;;;
;;;‘XXXXXXXXXXXXXXXXXXXXXXX’
;;;‘XXXXX I-Worm.Japanize XXXXX’
;;;‘XXXXXXXXXXXXXXXXXXXXXXX’

Name : I-Worm.Kevlar
Author : PetiK
Date : August 7th 2001 - August 16th 2001
Size : 5120 byte
Action : Copy itself to %System%\Kevlar32.exe hidden attribute
%System%\MScfg32.exe normal attribute
Add HKLM\Software\Microsoft\Windows\CurrentVersion\Run\Kevlar32 = %System%\Kevlar32.exe
* Infect %Windir%\C???????.exe file on writing as "PetiK" in the file
* Infect %Windir%\*.exe It add .htm and create a new file with ActiveX
* Create C:\__.vbs This filetake all address in th e Address Book at save them in the
%windir%\AddBook.txt. The worm scan this file to find the address and send a new mail :
Subject : Windows Protect !!
Body : The smallest software to stop your computer to bug in each time.
I have found this program on WWW.KEVLAR-PROTECT.COM
Take a look at the attchment.
Bye and have a nice day.
Attachment : MScfg32.exe
* It creates the %windir%\MSinfo32.txt. I look like this :
[File Infected] => Name of C???????.exe file infected
CLEANMGR.EXE=Infected by W32.Kevlar.PetiK
CVTAPLOG.EXE=Infected by W32.Kevlar.PetiK
[EMail saved] => Some address found in the address book
first@mail.com=Next victim
second@mail.com=Next victim
To build the worm:
tasm32 /M /ML Kevlar
tlink32 -Tpe -aa -x Kevlar,,,import32
upx -9 Kevlar.exe
To delete the worm:
@echo off
del %windir%\system\Kevlar32.exe
del %windir%\system\MScfg32.exe
del %windir%\*.exe.htm
del %windir%\MSinfo32.txt
del %windir%\AddBook.txt

Name : I-Worm.MaLoTeYa
Author : PetiK
Date : July 2nd - July 6th
Size : 12288 byte
Action: It copies itself to \WINDOWS\RUNW32.EXE and to \WINDOWS\SYSTEM\MSVA.EXE. It alters the
run= line and creates the VARegistered.htm file in the StartUp folder. This file send some
informations to petik@multimania.com and displays a fake message.
If the version of the platform is Windows 95/98, the file is a service process.
It infects all *.htm and *.html file while writing at the end a VB script. It checks after
if exist a internet connection and scans all *.htm* files in the "Temporary Internet Files"
to find some EMail addreses and send a copy of itself. The worms sends equally an email to
"petik@multimania.com" with the country of the user. When the user want to see the
system properties, the title of the window is changed by "PetiK always is with you :-)".
