이름: Backdoor-W32/IRCBot.62976

바이러스 종류: Backdoor

실행환경: Windows

증상요약: Worm-W32/IRCBot 의 변형 중 하나이다. 이 Backdoor는 윈도우 취약점과 윈도우 사용자 계정의 취약한 암호를 통해 전파된다. 해당 Backdoor 가 실행되면 윈도우 시스템 폴더에 vmmon32.exe 파일을 생성하고 자신을 레지스트리에 등록하여 윈도우 시작시 자동으로 실행되게 만든다. 그리고 특정 IRC 서버의 채널에 접속하여 오퍼(방장)가 내리는 명령에 따라 여러가지 악의적인 일을 수행하게 된다.

위험등급: 위험

확산방법: 네트워크, 보안취약점

치료방법: 터보백신 제품군으로 진단/치료 가능합니다.
