Between May 29 and May 31, 2020, the Wordfence Firewall blocked over 130 million attacks intended to harvest database credentials from 1.3 million sites by downloading their configuration files.
The peak of this attack campaign occurred on May 30, 2020. At this point, attacks from this campaign accounted for 75% of all attempted exploits of plugin and theme vulnerabilities across the WordPress ecosystem.
We were able to link these attacks to the same threat actor previously targeting XSS vulnerabilities at a similar scale. All Wordfence users, including Wordfence Premium and those still using the free version of Wordfence, are protected by our firewall’s built-in directory traversal protection.
