vbs scripts

VBS scripts remain a common vector in modern malware chains, as highlighted by a recent Microsoft warning about a WhatsApp-delivered campaign. Attackers use malicious VBS scripts to stage hidden folders, rename legitimate Windows tools like curl.exe and bitsadmin.exe, and fetch additional payloads from cloud services. The chain ultimately deploys unsigned MSI installers that grant remote access to the victim's machine. This technique blends into normal enterprise activity, making detection difficult. For Windows users, understanding how VBS scripts are abused in such attacks is key to recognizing and preventing similar threats.
