 ===================
 
 A collection of PHP exploit scripts, found when investigating hacked servers. These are stored for educational purposes and to test fuzzers and vulnerability scanners. Feel free to contribute.

+Why do you put these online? They're dangerous!
+===============================================
+
+Yes, obviously. Don't copy them and store them on your own server. These are scripts found on hacked systems, so they're used to exploit the server and abuse some kind of vulnerability.
+
+They're not dangerous in themselves. If anyone exploit a server or CMS, they can upload far more dangerous tools than these PHP scripts.
