Botnet: Cutwail Returns; Overall Spam Increasing
Cutwail had its heyday about five years ago, when it led the botnet activity list with 1.6 million infected computers. However, it lost its top position in the market after hackers intruded into the system and disclosed the names of customers and affiliates.
According to M86 Security, the volume of infected emails was 50 times higher between 23 and 25 January, and three further waves from 6 February were found to be as much as 200 times higher.
Infected emails had subject lines such as “FDIC Suspended Bank Account”, “End of August Statement” and “Scan from Xerox WorkCentre”.
