Summary

Hide ▲

The WordPress compromise campaign is turning site visits into a malware delivery path, redirecting users to ClickFix-style pages and fake Cloudflare verification screens. Attackers injected malicious JavaScript through functions.php and used remote loaders on brazilc[.]com and porsasystem[.]com to serve the payload. The activity matters because it reaches normal visitors through trusted websites and can hand them off to malware pages. It also hides behind legitimate-looking ads and browser-challenge branding to reduce suspicion.
