According to ACE Spark, the website has been infected with the HTML:iframe-inf virus (AKA: W32/Virut). The virus affects the following:
Overview -
W32/Virut.h is a polymorphic, entry point obscuring (EPO) file infector with IRC bot functionality. It can accept commands to download other malware on the compromised machine.
It appends to the end of the last section of executable (PE) files an encrypted copy of its code. The decryptor is polymorphic and can be located either:
* Immediately before the encrypted code at the end of the last section
* At the end of the code section of the infected host in 'slack-space' (assuming there is any)
* At the original entry point of the host (overwriting the original host code)
The decryptor will either receive control directly or an API call within the host code body will be overwritten to point to it (EPO technique). In all cases where host code is overwritten by the virus the original bytes are stored within the encrypted virus body, and are restored before transfering control back to the host. This virus may also infect the files multiple times.
Aliases
* W32.Virut.R (Symantec)
Characteristics -
When W32/Virut.h is executed it injects its code into running processes.
W32/Virut.h opens up backdoor on the compromised machine at port 80 (HTTP) but uses it for IRC communication.
This virus tries to connect to IRC server located at :
* eircd.zief.pl
And joins the channel named: virtu
It can then receive commands to download and execute other malware on the infected machine. Though the download location in the commands can change, at the time of writing, the virus tried to download malware executables from:
*
http://85.114.[REMOVED]/~grander/[MALWARE].exe
Symptoms -
* Modified executable files (increase in the size of exe files)
* DNS queries to eircd.zief.pl and IRC related network traffic
Method of Infection -
W32/Virut.h is a file infecting virus. Infection starts with manual execution of the binary. Executables in network shares may also get infected if accessed by the compromised machine.
The virus has a number of bugs in its code, and as a result it may misinfect a proportion of executable files. In those cases of misinfection in which repair data is present within the virus body, and has not been miscalculated by it, the current DAT set will repair the virus as per the non-corrupted case. However, unfortunately, some W32/Virut.h infections are corrupted beyond repair.
ACE is currently working out the problem and should see a clean website by the end of next week.
(BTW, I know there's people on this board that don't give a hoot about SI, but this virus can infect this site as well.)
Marc, I recommend that all files be scanned with
this.
