홈페이가 돌아가고 있는 서버입니다..
설치한지 얼마되지는 않았구요
그래도 혹시나하고 chkrootkit을 돌려 봤습니다
# ./chkrootk > find2.txt
# more find2.txt를 했습니다
--중간생략--
Checking `z2'...Checking `wted'...Nothing deleted
Checking `sniffer'...
eth0 is not promisc
Checking `aliens'...No suspect files
Searching for sniffer's logs, please wait MANY minutes...Nothing found
Searching for t0rn's default files and dirs ...Nothing found
Checking `lkm'...You have 11 process hidden for readdir command
You have 11 process hidden for ps command
Warning: Possible LKM Trojan instaled
이렇게 나오네요
그래서 chkproc -v를 몇번 해봤는데요 나오는 내용은 같습니다
[root@www chkrootkit-0.17]# ./chkproc -v
You have 11 process hidden for readdir command
You have 11 process hidden for ps command
[root@www chkrootkit-0.17]#
이렇게 나옵니다
제 생각에는 lkm이 install이 된것 같은데요
어떤 프로세스가 lkm인지 모르겠습니다..
[root@www chkrootkit-0.17]# ps -aux |more
