Exploit-Challenges

Here are a collection of vulnerable ARM binaries designed for beginner vulnerability researchers & exploit developers to play around with and test their skills!

These binaries are all built as ARMv7 Mach-O executables (unless specified otherwise) so it is recommended that you use a 32bit jailbroken iOS device with radare2 or another debugging utility installed to test them.

ARM 32-bit

roplevel1 - simple introduction to Return Oriented Programming with a simple objective

roplevel2 - same idea as level 1 but with a new objective

roplevel3 - more advanced use of ROP

roplevel4 - dealing with ASLR (infoleak)

roplevel5 - same as lvl4 but requires exploitation of format string vuln for the info leak

roplevel6 - execute ROP chain by making use of a stack pivot

roplevel7 - off-by-one vulnerability

heaplevel1 - simple heap based overflow example

heaplevel2 - Use-After-Free exploit

heaplevel3 - double free()

Xylex - real-world(ish) example system

ARM 64-bit

roplevel1-64 - 64-bit version of roplevel1

roplevel6-64 - 64-bit version of roplevel6

Help & Guidance

Write-ups/explanations on some of the binaries can be found on my YouTube channel here or in my book Beginner's Guide to Exploitation on ARM.
