And the Bagles just keep on coming

A quick update: over the last twenty four hours, we had eleven new Bagle variants, from Bagle.bz to Bagle.cj. Some of them were new versions, and some were old variants which had been repacked.

All the new versions were either spammed, or placed on sites for download. They’re being used to ensure that the Bagle botnet survives.

A very old Bagle variant was also spammed; it had been repacked using a new version of the packing program.

The Bagle bakery is clearly still in business, but hasn’t come up with any new recipes for a while.
