Hackers are breaching WordPress sites by exploiting a vulnerability in outdated versions of the Popup Builder plugin, infecting over 3,300 websites with malicious code.
Sucuri says the exact actions of the code may vary, but the primary purpose of the injections appears to be redirecting visitors of infected sites to malicious destinations such as phishing pages and malware-dropping sites.
WordPress stats show that at least 80,000 active sites currently use Popup Builder 4.1 and older, so the attack surface remains significant.
