Antivirus company SecureWorks has published a
detailed analysis of the unique Trojan SpamThru , which experts have already dubbed
"the most sophisticated virus in history .
"Getting into the computer, the pest not only uses it as a host for sending spam, but also ensures that its work is not interfered with by competitors. SpamThru installs on an infected Kaspersky Anti-Virus machine (the pirated distribution is downloaded from a remote server) and ensures that no other viruses penetrate the system and do not claim resources.
In addition, the Trojan uses the AES cryptographic cipher, supports P2P protocols, and generates graphical spam, where each individual letter is slightly different from the other.
