Problemas com rootkits
« Online: 25 de Agosto de 2010, 15:59 »
Eu instalei o rkhunter no meu ubuntu 10.4 e fiz uma verificação e apareceu isso:
Warning: Suspicious file types found in /dev:
         /dev/shm/pulse-shm-936414828: COM executable for DOS
         /dev/shm/pulse-shm-225158475: data
         /dev/shm/pulse-shm-3855249895: data
         /dev/shm/pulse-shm-2400955990: data
         /dev/shm/pulse-shm-1879171192: data
Warning: Hidden directory found: /etc/.java
Warning: Hidden directory found: /dev/.udev
Warning: Hidden directory found: /dev/.initramfs

One or more warnings have been found while checking the system.
Please check the log file (/var/log/rkhunter.log)
Então tentei abrir o log so que apareceu que eu nao tinha a permissão necessária para abrir aquele arquivo. Devo me preocupar? Como posso remover o possivel rootkit?
