Microsoft has announced that it will release an update for the ANI vulnerability on Tuesday the 3rd of April. This is a week early as they usually release security patches on every second Tuesday of the month but as there is an increasing activity of sites and malware using the ANI vulnerability, they decided to release it early.
You might wonder how they were able to get the update out so quickly considering it was first used in exploits late last week. The issue of the ANI vulnerability was actually brought to Microsoft's attention back in December 2006 according to their their Security Response Blog and they've been investigating and working on a fix since then.
Until Microsoft has released the update, you can count on us to continue adding detection for known versions of the ANI exploit and worms.
