Zemra ,a new Distributed Denial of Service (DDoS) crimeware bot


A Distributed Denial of Service (DDoS) crimeware bot known as "Zemra" has been identified by Symantec Researchers. This threat has been observed performing denial-of-service attacks against organizations with the purpose of extortion.

Zemra first appeared on underground forums in May 2012 at a cost of €100($125).

This crimeware pack is similar to other crime packs, such as Zeus and SpyEye, in that is has a command-and-control panel hosted on a remote server. This allows it to issue commands to compromised computers and act as the gateway to record the number of infections and bots at the attacker's disposal.

Zemra uses 256-bit DES encryption/decryption for communication between server and client;and it can spread via USB devices.

Researchers revealed that the main functionality is the ability to perform a DDoS attack on a remote target computer of the user's choosing.
