[IDG] One of the world's most active spam botnets -- Grum -- was crippled after two of its command and control (CnC) servers hosted in the Netherlands were taken down, according to researchers from security firm FireEye.
"These two CnC servers were responsible for pumping spam instructions to their zombies," said FireEye senior staff scientist Atif Mushtaq in a blog post on Tuesday. "With these two servers offline, the spam template inside Grum's memory will soon time out and the zombies will try to fetch new instructions but will not able to find them."
