Re: Hysterical first technical alert from US-CERT



Hi!

I just got the alert below from US-CERT. It's one of the new lists they started. Some things about it bother me. First, it's dated 1/28, the day MyDoom.B was discovered, and the message sent field says that too; other dates in the headers disagree.

Yes, I got this report as well and I agree with you that MyDoom.B was not able to spread widely at all. It looks like a mistake to me -- maybe they wanted to warn for MyDoom.A instead of MyDoomB.?

At the time of the writing, Trend Micro's online scanner HouseCall has found and cleaned more than 900.000 MyDoom.A-infected machines:

However, they only found 7 (seven) MyDoom.B infected PCs world-wide:

At least one av company has send out a wrong alert for MyDoom.B as well (they wanted to update their MyDoom.A advisory, but they mixed-up both worms descriptions).

A German news about this possible false alert can be found here:
