Ullrich<\/a>, Dean of Research at Sans Technology Insitute, describes two-stage attacks that start with probing SQL injection to confirm the vulnerability before delivering a PHP webshell to the server.<\/p>\n<p>The webshell was created under the \/wp-content\/cache\/ directory with a randomized filename that was also used as a password to access it via variable in an URL request; otherwise, the page returned a\u00a0fake 404 page.<\/p>\n<p>The webshell code that Ullrich published checked the availability of several PHP functions\u00a0&#8211; system(), passthru(), exec(), shell_exec(), popen(), or the backtick operator, in an attempt to execute commands.<\/p>\n<p>According to Ullrich, some attacks also involve creating rogue administrator accounts. As such, the researcher recommends checking the \/cache\/ directory and looking for newly created users.<\/p>\n<p>WordPress security firm Defiant has also published an <a href=\"https:\/\/www.wordfence.com\/blog\/2026\/07\/wp2shell-aftermath-the-first-critical-unauthenticated-wordpress-core-rce-in-nearly-a-decade\/\" rel=\"nofollow noopener\" target=\"_blank\">\u201caftermath\u201d post<\/a> stating that the first exploitation-related probing was observed at 23:29 UTC on July 17, followed by a clear SQL injection attempt just 13 minutes later.<\/p>\n<p>Administrators of WordPress sites should immediately update to the patched versions, review logs for wp2shell-related requests, inspect installed plugins, and check for rogue PHP file additions or newly created admin accounts.<\/p>\n<p>Macnica researcher Yutaka Sejiyama has <a href=\"https:\/\/wp2shell-global.nekono-nanomotoni.workers.dev\/wp2shell-global-public-dashboard#update\" rel=\"nofollow noopener\" target=\"_blank\">created a dashboard<\/a> that helps track the patch rate live.
