MessageLabs Intelligence virus advisory: W32/Bagle.C-mm (HIGH LEVEL)

Feb 29, 2004 11:26PM PST

Warning - new Bagle variant in the wild

MessageLabs, the leading provider of managed email security services to businesses worldwide, is warning computer users against the W32/Bagle.C-mm worm, another variant of the Bagle worm family.

Name: W32/Bagle.C-mm
Number of copies intercepted so far: 14, 521
Time & Date first Captured: 27th Feb 2004, 21.44 GMT
Origin of first intercepted copy: Korea

W32/Bagle.C is a mass mailing worm that harvests email addresses from infected machines and uses its own SMTP engine to propagate. The sender field of the email is spoofed, making it difficult for computer users to identify the source of the message. This worm also incorporates a remote access Trojan capable of alerting a remote hacker of the compromised machine.

Similar to previous incarnations of the worm, W32/Bagle.C will check the date and if later than 14th March 2004 will delete itself without propagating.
