Subject: "New" Brazilian Home Banking Trojan

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.
