Sparta.d

Sparta.d is a backdoor controlled through IRC channels. It gives the attacker unauthorized remote access to a compromised PC. The intruder can manage running processes, download and execute arbitrary files, collect computer information, scan hosts in a local network and reconfigure the backdoor. Sparta.d can also be used to record all user keystrokes and run a hidden FTP server. The threat hides its running components by injecting malicious code into legitimate computer processes such as winlogon.exe. Sparta.d runs on every Windows startup.
