Beware of Deceptive Windows Updates: New Malicious Ransomware Alert
A new ransomware called Big Head is disguising itself as fake Windows updates and Word installers as part of a malvertising campaign. The ransomware infects devices and encrypts files by displaying a fake Windows update alert. It can delete backups, disable Task Manager, and steal web browser history and other information. To protect against ransomware attacks, users should avoid opening sketchy-looking emails, have good antivirus software, regularly back up files on an external hard drive or cloud service, and keep software up to date.
