People should not be fooled by a worm pretending to be a security patch, an antivirus company is warning.
According to Sophos, the Stration worm, which is =spreading via emails, poses as a security update message, playing on peoples' concerns about an unpatched vulnerability in Microsoft's software.
The email features the subject line: 'Mail server report' and says: Our firewall determined the e-mails containing worm copies are being sent from your computer. Because this is a new virus type (Network Worms)... Please install updates for worm elimination and your computer restoring' .
The Stration worm message arrives with the attached file Update-KB7859-x86.zip which contains Update-KB7859-x86.exe.
"It's possible that those behind the Stration worm are playing on the internet community's heightened concern over being left unprotected by Microsoft. As a result the perpetrators may be able to fool innocent users into rushing into running the malicious update," Graham Cluley, senior technology consultant for Sophos said.
Security experts advise computer users to not open any email coming from unknown sources as security patches can only be sent by the security company's official website, not from an unsolicited email.
