ZeroAccess / Sirefef Rootkit - 5 fresh samples


Stocking stuffers.
ZeroAccess rootkit is far from new and exciting but but this is a fresh lot with still active C2 servers.
Although the dropper is detected by at least half of AV engines, post infection detection is another story. I tried Kaspersky TDSS Killer, Avast Rootkit utility and RootRepeal without any success. I used Gmer and LordPE to carve out the hidden file from the memory. You can use Redline or Volatility too.
You can download 5 files below together with pcaps from one of the files and the file dumped from memory. It appears that free videos and apps names are used as the lure in this case.

    was wondering if you were aware that the pcaps have geo IP data that reveal lat/long coordinates of a residence, you should probably take them down if they are sensitive

      I am aware. It is not a residence. It is a proxy IP of the sandbox - if you go there, will probably find a large data center.
      Thanks for the notice but it is ok.
