It seems like there are two new unique observables identified in Black Energy used in Sandworm operation:
  • Bots started to receive "destr" command, which destroys hard disk by overwriting with random data (on application level and driver level) at a certain time.
  • Bots also use Google+ to check if botnet master changed IP address of the CnC server. The bots fetch profile image and decode it in search for the new IP using stenography algorithms.
