Guest guest Posted June 14, 2006 Report Share Posted June 14, 2006 This is the latest of what I've read: (I personally did as they suggested, blocking emails from av3@...) (And I will probably run a virus scan on my computer - just in case...) (Also, been trying to figure out how to " modify their settings to block the zero-day exploit " -- when/if I figure it out I'll post it.) Worm Attacks Yahoo E-Mail Kirk, IDG News Service Monday, June 12, 2006 A mass-mail worm that exploits a vulnerability in Yahoo's Web-based e- mail is making the rounds but the impact appears to be low, security vendor Symantec said today. The worm, which Symantec calls JS.Yamanner@m, is different from others in that a user merely has to open the e-mail to cause it to run, said Hogan, senior manager for Symantec Security Response. Mass-mail worms have usually been contained in an attachment with an e-mail note encouraging a user to open it. The worm, written in JavaScript, takes advantage of a vulnerability that allows scripts embedded in HTML e-mail to run in the users' browsers. Yahoo users should be able to modify their settings to block the zero-day exploit, Hogan said. Symantec rated the worm a Level 2 threat, one notch above its least harmful ranking. Hogan said the worm did not appear to be spreading widely, and he did not anticipate the threat level rising. How It Spreads When activated, the worms then sends itself to other users in the victim's address book who also use Yahoo e-mail with the suffixes of @yahoo.com or . The worm mimics a function within Yahoo's Web mail called " Quickbuilder, " which allows a user to add contacts in an address book from received e-mail, Hogan said. The process, however, is transparent to the victim, he said. The harvested e-mail addresses are sent to a remote server. Users of Yahoo Mail Beta do not appear to be affected, Symantec said. The worm also opens a browser that displays a Web page that does not appear to contain malicious content. Although Yahoo's Web e-mail has not been fixed, users are advised to update virus and firewall definitions and block any e-mail sent from av3@.... The subject line of the e-mail with the worm says " New Graphic Site, " and the body says " this is test. " Yahoo officials could not immediately be reached for comment. The foregoing news article was from the PC World web site ----- Yahoo Says E-Mail Worm Now Contained Yahoo Says E-Mail Worm 'Yamanner' Has Been Contained SUNNYVALE, Calif. Jun 13, 2006 (AP)— Yahoo Inc. said Tuesday it has contained a malicious program aimed at the millions of people who use its e-mail service, which ranks as the world's largest. The worm, dubbed " Yamanner, " infected a recipient's computer as soon as the toxic e-mail was opened. It then scanned contact lists for additional targets, according to security software maker Symantec Corp. Sunnyvale, Calif.-based Yahoo said " a very small fraction " of its more than 200 million e-mail accounts were infected Monday when the problem was first identified. The worm didn't affect the next version of Yahoo's e-mail service, which remains in its test, or " beta, " phase. " We have taken steps to resolve the issue and protect our users from further attacks of this worm, " Yahoo spokeswoman Kelley Podboy said. " The solution has been automatically distributed to all Yahoo Mail customers, and requires no additional action on the part of the user. " As a precaution against variations on the Yamanner worm, Yahoo advised its e-mail users to update their antivirus programs and block all incoming correspondence from av3(at)yahoo.com. The worm arrived in the form of an e-mail containing JavaScript and contains the words " New Graphic Site " in the subject field, according to Symantec, the maker of Norton antivirus software. Unlike many worms that require an attachment to be opened, the latest bug was unleashed as soon as the e-mail was opened. It burrowed into e-mail contact lists in search of addresses containing the domains yahoo.com and yahoogroups.com, according to Symantec. Copyright 2006 The Associated Press. All rights reserved.
