Starting yesterday, our sensors picked up a small number of scans for "wordfence-waf.php". This particular script is used by Wordfence, a solution to protect WordPress sites. During the Wordfence install, the wordpress-waf.php file will be created in the site&#;x26;#;39;s root directory [1].
Keeping malware out
- Keep operating systems, browsers and plugins patched – most malware arrives through known holes.
- Block macros and scripts from the internet, and let only approved software run where you can.
- Watch endpoint alerts for new persistence: scheduled tasks, services and run keys.

- Expect exploitation to follow mass scanning of a product you run.
- Close ports and services you don't need on the internet.
- Feed scanner addresses from threat intelligence into your alerting.
