Hackers are actively exploiting a critical WordPress plugin vulnerability that allows them to completely wipe all website databases and, in some cases, seize complete control of affected sites.
The flaw is in the ThemeGrill Demo Importer installed on some 100,000 sites, and it was disclosed over the weekend by Website security company WebARX. By Tuesday, WebArx reported that the flaw was under active exploit with almost 17,000 attacks blocked so far. Hanno Böck, a journalist who works for Golem.de, also spotted active attacks and reported them on Twitter.
