A large-scale campaign dubbed ShadowCaptcha has compromised more than 100 WordPress sites worldwide, redirecting visitors to fake CAPTCHA pages that employ the ClickFix tactic to deliver information stealers, ransomware, and cryptocurrency miners. Impacted industries include technology, healthcare, finance, hospitality, and real estate, with sites in Australia, Brazil, Italy, Canada, Colombia, and Israel most affected. Researchers warn that ShadowCaptcha demonstrates how social engineering has evolved into full-spectrum cyber operations, blending credential theft, persistence, and ransomware monetization.
There’s a really good rundown on this campaign here: ShadowCaptcha Campaig Targets WordPress Sites with Malware
Gunter Ollmann, CTO, Cobalt had this comment:
“ShadowCaptcha is a stark reminder that social engineering has matured into an industrialized cybercrime model. What begins with a simple CAPTCHA lure now escalates into credential theft, ransomware, or even crypto mining—all without exploiting a traditional software vulnerability. The use of LOLBins, obfuscation, and vulnerable drivers shows how attackers are increasingly weaponizing legitimate tools to maintain stealth and maximize profits. Defenders need to rethink their assumptions: hardening infrastructure alone is not enough, security strategies must also focus on disrupting attacker workflows and continuously validating user behavior to blunt the impact of these evolving campaigns.”
Since I host this blog via WordPress, this gets my attention. I do use MFA and I do updates as soon as they come out. Thus I believe that I am secure. But you have to wonder about the thousands of WordPress sites that are out there.
