Ce qui confirme qu'il n'y a pas d'authentification.
D'urgence j'installerais chkrootkit et je lancerais la commande sudo chkrootkit.
Quelle est sa date de dernière modification ?
ls -lc /var/log/auth.log
Il faut analyser le processus de démarrage dmsg.
Rechercher d'éventuelles erreurs.
commencer par
dmesg |grep -i -A5 error
parcourir dmesg à la recherche d'anomalies...
dmesg|less
Ça me parait grave. Il vaut mieux éviter de faire des achats ou de te connecter à ta banque...
