Technical Details



Instant Messenger trojans are usually standalone programs that are sent by hackers to their potential victims in e-mails or instant messages. IM trojans are most frequently used to steal user's IM account information. When such trojan is run, it tries to locate an IM client's user information and to send it to a hacker via e-mail or using the existing IM client. That way a hacker gets all data he needs to connect to an IM network using victim's credentials.

Most famous IM trojans: Ypager, Ikmet, Spy, ICQSteal.
