I'm proud to announce the release of Project Hijack 0.2. It's available as a shared library for easy integration with current and new projects. Libhijack 0.2 makes injecting arbitrary code incredibly easy. 32bit Linux systems are supported. 64bit Linux systems are mostly supported, with one known bug.
I've been working on this version for the past few months and am excited to see this project take off. I'll be working on fixing the 64bit bug (and will probably release 0.2.1 with the fix) then move on to injecting other shared objects, rather than just shellcode.
Head over to Project Hijack's home to download Project Hijack 0.2.
