Worm Attacks Yahoo! Mail

Early Monday, June 12, 2006, it was discovered that the most popular Web based e-mail of Yahoo! was being exploited. The threat is a mass mailing worm that uses a vulnerability within av3@yahoo.com ^[1] into your Blocked Addresses List. This is easy and only takes a few seconds.

1. Open up and log into your Yahoo! e-mail account.
2. Go over the far right of the main interface and select Options.
3. From within the Options page, choose the option to Block Addresses.

4. This will take you to another page where you will see a blank field right under the heading “Block Addresses.” Simply type the e-mail address of any undesirable e-mail. In this case, we’ll use av3@yahoo.com ^[1]) in you Yahoo! account. If you do all of this, you should be fine. Until next week, stay safe out there.
