vps ssh weak password

Bonjour,
Alors j'ai décidé de prendre un vps chez un autre hébergeur, le vps prend 1 jour a s'activer etc mais normal on est en week-end rien de grave cependant n'ayant pas attendu, je viens tout juste de me connecter et voit que mon vps a un uptime de 15h et avec le port ssh standard et un mot de passe de 8 caractère [a-z] donc sans majuscule ni nombre que des minuscules qui prendrait moins de 2 minutes a bruteforce par un gros botnet maintenant je ne sais pas quoi faire je ne sais même pas si je peut vraiment me fier aux logs ssh du coup si le serveur serrait compromiser

Concernant les logs ssh tout a l'air d'être ok pas de tentative fructueuse, j'allais dire même pas assez de tentative de bruteforce a mon goût...

donc quoi faire ?

salut,

moi c'est un peu pareil, quand je vois mon verre rempli d'eau, je me rends assez vite compte que je pourrais me noyer rien qu'en le buvant, du coup je sais plus quoi faire, arrêter de boire me semble être la solution la plus safe

alors selon chez qui tu le prends ton VPS dans le réseau du fournisseur y'a des outils de détection en temps réel de DDoS, de bruteforce et de scans latéraux, et c'est vachement bien fait; ça marche aussi bien en entrée qu'en sortie, et en sortie tu te fais shutdown ta machine, donc tu peux en déduire que si ton VPS est toujours allumé c'est soit que le méchant botnet sait plus quoi faire une fois root, soit que ton VPS est pas à ce point le centre du monde, au choix.

par ailleurs un bruteforce sur 8 caractères, ça se fait rapidement en local, en réseau t'es limité par la bande passante au minimum, probablement par le login ssh également qui perd quelques fractions de secondes à chaque essai, et encore une fois un bruteforce réseau ça ne passe pas inaperçu, c'est *très* bruyant

enfin comme tout bon VPS, tu dois avoir la possibilité de réinstaller en quelques minutes, si le système est comme neuf et que t'as un doute suffit de réinstaller et on en parle plus

c'est très beau par contre aucune idée de ce que ça veut dire ça ne t’empêche pas de continuer, j'aime bien et moi aussi j'aimerais bien faire des phrases comme ça mais j'en suis incapable :(
non malheureusement pas de possibilité de réinstaller sinon j'aurais pas demander :)

ça veut dire arrête d'être parano, ton VPS s'est pas fait hacker, utilises-le et te prends pas la tête.

je compatis, si ça peut te consoler je me donne moi-même beaucoup de mal, même parfois trop, de la confiture pour les cochons :lol:

j'ai comme un très gros doute là dessus mais bon... faisons simple alors : mauvais hébergeur, changer hébergeur.

:applo:

Étant relativement paranoiaque voilà les logs du premier jour pour les autres je suis "relativement" confiant, pour moi tout à l'air d'être ok
