PHP2Shell Attacks Root Palo Alto Firewalls but Fail Against WordPress

By Ionut Arghire

AI Summary

PHP2Shell attacks are actively exploiting critical PHP vulnerabilities against Palo Alto firewall web interfaces, with over 22.6 million exposed instances potentially at risk across more than a week of sustained exploitation. The campaign has been less effective against WordPress targets despite attempts. Defenders managing Palo Alto devices with exposed management interfaces should apply PHP patches immediately and audit for indicators of compromise.
