A campaign targeting Windows users exploits WhatsApp attachments to execute a malicious .vbs script. Victims receive what appears to be a harmless attachment, which, when opened, duplicates legitimate Windows tools into a hidden folder and renames them to avoid detection. These tools are then used to download additional malware from reputable cloud services, disguising the malicious activity. The malware seeks administrator privileges by altering User Account Control settings and registry entries for persistence. It ultimately installs remote-access software and other payloads to maintain control over the compromised device. Malwarebytes recommends safety measures such as avoiding unsolicited attachments, enabling file extensions, using updated anti-malware tools, downloading software from official sites, being cautious of unexpected UAC prompts, and keeping systems updated.
