SlowHTTPTest is a highly configurable tool that simulates some Application Layer Denial of Service attacks. It works on majority of Linux platforms, OSX and Cygwin – a Unix-like environment and command-line interface for Microsoft Windows. I managed to crank up 504 connections from a single IP in less than 85 seconds – This is more than enough to bring down a server (well most small servers and VPS’s for sure). To make it worse, you can do it from Windows, Linux and even a MAC… I am starting to wonder whether you can do it using a jailbroken iphone6 Plus OTA (4gplus is FAST) … or a Galaxy Note 4.. I can do it using my old Galaxy Nexus (rooted) and of course good old Raspberry Pi
