이거 백도어인가요?

find /dev -type f

위 명령어를 쳐봤는데 아래처럼 무쟈게 많이 나왔습니다.

위에 더 있는데 잘렸구요.

백도어가 의심되는데 조언 부탁드립니다.

제가 질문의 의미를 잘 이해하지 못하겠군요.
혹은 질문하신 분이 이해를 못하셧거나…

제가 알기로는
1.
find /dev -type f 명령은… /dev 디렉토리의 모든 일반 파일을 표시하는 명령일테고…

/dev 디렉토리는 유닉스 시절부터 내려오는 …역할 설명은 패스하고…어째튼 "파일이 아주아주 많기로 유명한" 디렉토리죠…

1번과 2번의 조합은…당연히 결과값이 많을 것이라고 생각되는데…
어째서 그게 백도어의 가능성을 내포하는지요?

dev 디렉토리에 있는 파일들은 가상 장치 드라이버 입니다. (block device, character device)
시스템 디바이스나 자원들을 엑세스하는 데 사용됩니다.

아마 예전 문서에서 백도어 검출 명령어를 보신 모양 입니다. :shock:

백도어 검사 프로그램으로는 chkrootkit 설치 하시고 검사 해보십시요

sudo apt-get install chkrootkit
sudo -i
chkrootkit
