Olmarik, also known as Alureon, is a Windows rootkit family with variants associated with TDL4. Its rootkit functionality supports concealment of malicious activity on compromised systems. An updated variant detected as Win32/Olmarik.AIY and identified as TDL4 can elevate privileges by exploiting the Windows Task Scheduler vulnerability addressed by MS10-092.
