Some shell scripts that are useful for exploitation, though you should really use pwntools instead.

Shellcoding:

• assemble: build shellcode, assemble shellcode.s or assemble "mov rax, 60; syscall"
• disassemble: disassemble shellcode, disassemble shellcode.raw or disassemble <(echo -ne '\xcc')
• analyze: analyzes shellcode, analyze shellcode.elf
• lookup-syscall: lookup syscall number, lookup-syscall -a i686 read
• lookup-constant: print the value of a constant (really, any C expression): lookup-constant "PROT_EXEC|PROT_READ|PROT_WRITE"

Misc:

• run-c: compile a C expression into main and run it, c-run 'puts(argv[1]);' test

Management:

• setup.sh: add the scripts/ dir to your PATH via .bashrc
• update-syscalls.sh: update the syscall tables
• test.sh: some testcases
