An anonymous reader writes: "Attacks on WordPress sites using a vulnerability in the REST API, patched in WordPress version 4.7.2, have intensified over the past two days, as attackers have now defaced over 1.5 million pages, spread across 39,000 unique domains," reports BleepingComputer. "Initial attacks using the WordPress REST API flaw were reported on Monday by web security firm Sucuri, who said four groups of attackers defaced over 67,000 pages. The number grew to over 100,000 pages the next day, but according to a report from fellow web security firm WordFence, these numbers have skyrocketed today to over 1.5 million pages, as there are now 20 hacking groups involved in a defacement turf war." Making matters worse, over the weekend Google's Search Console service, formerly known as Google Webmaster, was sending out security alerts to people it shouldn't. Google attempted to send security alerts to all WordPress 4.7.0 and 4.7.1 website owners (vulnerable to the REST API flaw), but some emails reached WordPress 4.7.2 owners. Some of which misinterpreted the email and panicked, fearing their site might lose search engine ranking.
