Trojan creates havoc

Trojan creates havoc using antivirus vendor's name.

A Trojan horse disguised as a spam message from an antivirus company is making its rounds, security vendor Sophos has warned. The e-mail, which carries an attachment, appears to be sent from Helsinki-based security vendor F-Secure, the company said in a statement on its Web site. It comes with various subject headers, such as "Firefox Browsing Problem," "Mozilla Browsing Problem," or "Website Browsing Problem."

Graham Cluley, senior technology consultant at Sophos, noted that F-Secure has "done nothing wrong" and were "the unfortunate victims of Internet criminals using their name as a disguise in an attempt to spread malware." According to Sophos, the Trojan will disable antivirus and other security software, as well as open a backdoor for hackers to gain access to infected systems. Cluley added that running the attachment will "allow hackers to gain access to spy, steal and cause havoc." Vivian Yeo reported for ZDNetAsia.
