Security vendors are warning users of a massive surge in the amount of e-mail spam containing an updated version of the Storm Trojan threat.

The malicious spam threat, which was discovered earlier this year but has now been repackaged, has leapt up threat rankings recently, according to security vendor Postini. It currently accounts for 87% of all malware being spread through e-mail, the firm said.

Symantec has also issued an advisory about the malware, also known as Trojan.Peacomm, which arrives as an attachment to an e-mail purporting to contain a security patch.

The e-mail arrives with a variety of subject headings, including "worm detected!", "virus activity detected!", "spyware alert!", and "Trojan alert!", Symantec said. "Users are encouraged not to open e-mails including similar subjects," Symantec advised.

The e-mail appears to warn users about a malicious threat, but in fact the attachment itself is the threat.

The attachment is a password-protected zip file containing a Trojan horse that installs itself on a system as a system driver and then downloads other malicious programs from the internet.
