Nouvelle infection découverte par UsbFix : Bondat

A l’instar de l’infection Houdini, Bondat ce propage sur les supports USB et se dissimule grâce à des raccourcis piégés.

Infection Bondat

On s’aperçoit alors que le processus wscript.exe (Fichier légitime Microsoft Windows) lance l’infection Bondat .Trashes\490\qcckslogd.js puis le fichier de l’utilisateur : .Trashes\tc30406400a.exe

Le sous dossier créé dans le dossier .Trashes (Légitime) .Trashes\490 est aléatoire, rendant la détection plus compliquée pour les outils de désinfection.
Une copie de l’infection est placée dans le dossier %Temp% et dans %AppData%

C:\Users\%userName%\AppData\Local\Temp\nnbly.js
C:\Users\%userName%\AppData\Roaming\hcnmie\jdvbsjqyl.js
