Попробуй поискать suid-файлы
find / -perm +4000

Найти все файлы в системе с установлеными битами SUID и SGID, владельцем которых является root, можно командой:
find / -type f \( -perm -04000 -o -perm -02000 \) \-exec ls -lg {} \;

Для поиска всех файлов доступных на запись используйте команду
find / -type f \( -perm -2 -o -perm -20 \) -exec ls -lg {} \;

Для поиска всех каталогов доступных на запись - команда
find / -type d \( -perm -2 -o -perm -20 \) -exec ls -ldg {} \;

и
find / -name "pass"
find / -name ".htacces"
итд ....

Нашел, теперь нужно просматривать каждый файл с помощью cat?
