Protect Your Site with Sucuri Firewall
If you are a Joomla user, check your logs right away. We recommend searching your logs for “JDatabaseDriverMysqli” or “O:” in the User Agent as it has been used in the exploits. If you find them, consider your Joomla site compromised and move to the remediation / incident response phase.
Note that clients behind the Sucuri.net Website Firewall were already protected against this threat and are safe. Yes, the virtual patching for the HTTP User Agent kept their users protected against this exploit.
