Lounge of Tomorrow - Heads Up: Yahoo Mail Virus

Apparently this one can spread just by opening the email.

Yahoo email worm can infect without clicking attachments Print E-mail

Security vendor Symantec has identified a new JavaScript worm that exploits an unpatched vulnerability in Yahoo!'s web-based e-mail program. The worm can infect users' machines merely by opening a rogue email message - users do not even have to open an attachment for their system to get infected.

The worm - JS.Yamanner@m - spreads itself to the user's Yahoo! e-mail contacts when the user opens an e-mail infected by the worm. JS.Yamanner then sends these e-mail addresses to a remote server on the Internet. Only those using contacts with an e-mail address that is @yahoo.com or @yahoogroups.com are impacted by this worm. Users of Yahoo! Mail Beta do not appear to be vulnerable to JS.Yamanner.

Symantec has advised that as there is no patch at present, users should update antivirus definitions and firewall signatures and to block any e-mails sent from av3[at]yahoo.com.
