APK modification to bypass premium/license checks is a core mobile security assessment skill. The goal is to identify how the app determines "premium" status and subvert that logic. Here's the full workflow, from decompilation to repackaging.

The USB Rubber Ducky is the device that invented keystroke injection as an attack vector. It's a USB device that looks exactly like a generic flash drive but presents to the target computer as a USB keyboard. It types pre-programmed keystroke sequences at superhuman speed — up to 1000 words per second. Because it's seen as a keyboard by the OS, no antivirus, no application allow-listing, no endpoint detection stops it. Keyboards are trusted by default. There have been two har

Here's the complete workflow from blank file to shell on target, covering syntax, common patterns, compilation, testing, and deployment across all current Hak5 implant platforms. This article / guide is on how to create DuckyScript payloads.

DuckyScript is the domain-specific language created by Hak5 for programming keystroke injection attacks. It's the engine behind the USB Rubber Ducky, and now runs on nearly every Hak5 implant — O.MG Cable, Key Croc, Packet Squirrel Mark II, WiFi Pineapple Pager, Bash Bunny, and the Shark Jack. Despite its simple appearance, the language has evolved through three major generations with dramatically different capabilities.
