Backdoor.Sosork is a backdoor Trojan that opens a back door on the affected computer system. Backdoor.Sosork is usually downloaded by a malicious RTF document that exploits a vulnerability, such as the Microsoft Windows Common Controls ActiveX Control Remote Code Execution Vulnerability. Once executed, Backdoor.Sosork creates potentially malicious files on the infected computer. Backdoor.Sosork connects to a command-and-control (C&C) server. Backdoor.Sosork gathers the information including CPU, memory and computer name and transmits it to the C&C server.
