Over 100 hacked websites use fake verification prompts to deliver infostealer malware

Security researchers identified more than 100 compromised websites injected with malicious scripts that display fraudulent Cloudflare verification checks. Visitors are tricked into downloading LunexStealer, an information-stealing malware designed to swipe stored passwords and corporate credentials. This puts businesses at risk of account takeovers if employees browse compromised sites during regular work activities.
