A new e-mail worm masquerading as news headlines from CNN has the ability to log keystrokes and open backdoors for new threats, anti-virus vendor Sophos Inc. said in an advisory.

Researchers at Sophos said the worm, identified as W32/Crowt-A, takes its subject lines and message content from headlines gathered in real-time from Time Warner's CNN Web site. The worm's subject line and attachment share the same name, but continually change to mirror the front-page headline on the CNN site.
