> Hello,
> I'm receiving an homebanking trojan from Brazil. The email is 
> disguised as a patch for Orkut Bad Server and Errors.
> The download location is at 
> http://69.57.154.130/~arquivo/orkut-patch.exe .
> AVG detects it, Norton doesn't. Didn't had the opportunity to 
> test with other AV.
> 
> Some quick notes about this one:
> - It's packed with PECOMPACT 2.x. It can easily be unpacked 
> with Olly, using the PECOMPACT scripts (www.openrce.org for 
> example) and Ollydump.
> - You can extract a few Jpeg's from the unpacked binary. It 
> confirms it tries to attack homebanking accounts.
> - Strings reveals some 4 or 5 banks addresses.
> - Seems to be coded in Delphi.
> - It appears to email the stolen accounts to 2 accounts. At 
> least they are in the code.
> 
> I think it should be interesting for Malware Reverse 
> Engineering practice.
> No much spare time at the moment to give a look at it, so no 
> much details. 
> 
> It could be useful to AV vendors, since I'm not sure it's 
> being detected by all. I thought it was a new one in the 
> wild, until I tested with AVG :(
> 
> Best Regards,
> Pedro Hugo
> 
> P.S.: The first copy arrived 3 weeks ago, and today I have 
> received two more.
> If you want the original email, I can forward it.
