LdPinch…again.

Over the last few days new variants of Trojan-PSW.Win32.LdPinch have been spreading actively on the Russian internet. This Trojan has been mass mailed, and also spreads via ICQ. Email and ICQ messages may be from unknown users (usually a woman), or from users on your contact list.

There’s nothing really new here. New variants are included in the antivirus database updates we release every hour. So why are we writing about it?

The answer’s simple: lots of users have been careless enough to launch the attachment which contains the Trojan, or to click on the link in the ICQ message which leads to the Trojan. And then, as its name indicates, LdPinch steals passwords from the victim machine.

If you’re one of these users, to prevent any further damage you should:

  • Update your antivirus databases
  • Perform a full scan of your computer in order to remove the malicious code
  • Change all passwords for your email, ICQ, and other network applications

LdPinch…again.
