Bagle spreads new threat

Friday, 19 March 2004, 10:37 AM EST

Users no longer have to click on an attachment to spread the Bagle virus because the latest variants are exploiting an old flaw in Microsoft Outlook that allows the worm to spread even more quickly.

Until the appearance of Bagle variants Q, R and S, users had to click on an e-mailed attachment to be infected by the worm. However, these attachments were easily spotted by antivirus programs and eliminated. To fool antivirus software, the next batch of Bagles was sent with the attachment hidden insideinfected an encrypted Zip file, with the password to open the file contained in the e-mail's text. Antivirus companies dealt with this change within a few days, so in the next variant the password appeared in a small graphic file, making it more difficult to scan.
