ZeroAccess (or Sirefef) is a piece of malware that is very adept at hiding its existence from users, and brings in huge sums of money to its masters by performing click-fraud and Bitcoin mining.
The ZeroAccess botnet is currently one of the largest one in existence, but its creators have recently received quite a blow when Symantec researchers managed to sinkhole nearly half a million of its bots.
In this podcast recorded at the Virus Bulletin 2013, Candid Wüest from Symantec shares details about their research into the malware, the sinkholing operation they executed, and the lessons they learned from it.
