tmp.0ut Vol. 5: Inside a 57-byte x86-64 ELF and a 440-byte metamorphic virus

Tmp.0ut, Vol. 5

The fifth issue of the tmp.0ut zine is out, packed with low-level Linux and ELF hacking. Highlights include a 57-byte x86-64 ELF, a 440-byte metamorphic virus, and a deep dive into the Linux kernel's executable loader. Other pieces cover polyglot ELF files, syscall hook detection via side-channels, code virtualization, and a recap of BGGP6. An interview with Doug McIlroy offers historical perspective.
