It's not the first time that malwares are using detours techniques. 
In case your malware is "Trojan.Anserin"
(http://securityresponse.symantec.com/avcenter/venc/data/trojan.anserin.html)

It tries to hooks several APIs of the common browsers for keylogging/password stealing purposes (IEXPLORE, FIREFOX, 
MOZILLA, OPERA).
It tries to steal bank accounts and other confindential information.

Some variants try also to patch NSPR4.DLL (Netscape lib) altering
the following functions: PR_Connect(), PR_Read(), PR_Write(), PR_Close()

Subject: [Full-disclosure] Detours and Trojans


Detours is being used on trojans.
Just got one *sighs* and detours was making sure the processes could not be
killed.

the files were:
c:\Program Files\Common Files\Microsoft Shared\Web Folders\ibm00002.dll
(around 48k)
c:\Program Files\Common Files\Microsoft Shared\Web Folders\ibm00003.dll
(around 48k)
c:\Program Files\Common Files\Microsoft Shared\Web Folders\ibm00003.exe -->
this file was 2k
c:\Program Files\Common Files\Microsoft Shared\Web Folders\ibm00004.dll
(around 48k)

current user "Run" was mapped to ibm00003.exe above.

Unfortunatelly I deleted the files (in case anyone was interested), because
google did not show much info on this and I didn't know much more of what to
do.
did some strings on the files above and showed http posts (uploads) of some
local files.
sorry I don't have any more information. don't remember.

anyone saw this already?
