And the Bagles keep on coming

In the past two days, we’ve detected seven new versions of Bagle! The new variants range from Bagle.ax to Bagle.ba. Variants from Bagle.ba onwards are currently detected as Bagle.ba.

All these new variants are basically the same file, but packed, and they are very slightly different from each other. The full description of Bagle.ay basically covers all the new versions.

We’re continuing to monitor the situation, and will post any further news about the new Bagles here.
