The NSA just told companies to pull their websites offline if they can't patch them right away. The reason is a bug that's been sitting in the code behind 70% of websites for 14 years. Last Friday a guy found it in one evening by typing five words into an AI. Those five words

The one capture on the Oct 21 PHP flaw with a mechanism (the work of building an exploit used to be the protection, and AI made it cheap) plus numbers: unpatchable versus patchable servers and Microsoft's monthly fix count. The discovery timeline and the counts are his account; the PHP advisory and the Wiz write-up are not in the corpus. No source on file ties the cybersecurity stocks' Oct 21 move to this flaw.

Effective Immediately, all organizations using PHP for their systems are advised to be prepared for an update addressing two critical vulnerabilities. PHP is widely used for web applications. These vulnerabilities often provide a direct path to the server's file system or database. If an immediate update is not feasible, it is recommend that organizations take the system offline until it can be fully mitigated. NSA will follow up shortly with more specific guidance.
