Barracuda warns about CypherLoc browser scareware campaign
Campaign Scope UpdateBarracuda said CypherLoc, a browser-based scareware campaign, had been seen in around 2.8 million attacks since the start of 2026, typically arriving through phishing email links or attachments that send users to malicious pages. The pages use hidden code, URL fragment and cryptographic integrity checks to avoid scanners and sandboxes, then force the browser into full-screen mode, hide controls, display fake warnings and a fraudulent support phone number, and route callers to human operators posing as Microsoft support staff.
