Mal/Generic-L, Sus/CFNBehav-A and sdra64.exe

QC

I've seen several Mal/Generic-L detections reported lately. As they are infrequent and are dealt with by Sophos one way or the other I didn't think much about them. Today one has been detected on a co-workers machine right across the hall. Since the quarantine was empty (probably because of scan-on-write) I changed cleaning to "move", obtained the sample and sent it to Sophos. We first suspected something from a website (using Firefox) but as there were more detections (several minutes to more than half an hour apart) and also when Firefox was closed I started a scan (with HIPS scanning enabled). This time something turned up: sdra64.exe in the system32 directory detected (in the rootkit scan phase) as Sus/CFNBehav-A.

I've sent in this one too and am waiting for the results.

    Looks like more than flowers and leaves sprouts in spring. A "version" of sdra64.exe (not detected as any known threat) triggered HIPS/RegMod-001, HIPS/RegMod-014, HIPS/ProcInj-001. It was running from the user's Application Data folder and locked. Found the "original" in the Temporary Internet Files folder together with another rogue js and perhaps identified the site visited by the user (loads like molasses by the way). No signs of Mal/Dropper-AB mentioned in this article though.

    We'll see what Sophos Labs say.
