Bagle variants floods inboxes worldwide

Iain Thomson writes in vnunet.com:

Businesses are being urged to update their antivirus protection after the author of a new Bagle variant launched two mass spamming campaigns to spread the malware.

[One of the variants...] The BagleDL-U Trojan is enclosed in an email with no header. The message reads 'new price' and contains a zipped attachment.

Once installed it allows the computer to be used as part of a botnet of slave PCs controlled via IRC. It also shuts down any antivirus and anti-spam software and blocks access to security websites.

"This is the second massive email attack phase from this hacker in two days. He is intent on infecting as many people as possible," said Carole Theriault, senior security consultant at Sophos.

"All computer users must avoid opening unsolicited email attachments, and ensure that their antivirus protection is up to date.
