#### DATE CHANGE ## 16-DEC 15-DEC An introduction to ARM64 Assembly and Shellcode An Introduction to ARM64 Assembly and Shellcode is a workshop for those interested in getting a quick start into the world of 64-bit ARM binary exploitation. ARM64 is in several ways vastly different than ARM32. Participants will get to learn the key differences between ARM32 and ARM64 from an assembly language perspective, get some hands-on introduction to writing simple ARM64 assembly code, working with a debugging environment and concluding with writing their own ARM64 shellcode. This workshop is a precursor to an all new training - The ARM64 Exploit Laboratory, which debuts at Ringzer0 RETUR23XPLOIT! #### PREREQUISITES * Linux system with Docker installed and running * Working comfortably with the Unix command line * Familiarity with GDB command line usage **AUDIENCE** Beginner to Intermediate **DURATION** 2 hours lecture/demo
