Pym’s is an x86 disassembler packaged as a web application. It now includes a new feature, that I like to call “shellcode disassembly for really lazy dudes”. Just paste a C
char* in the textbox and let the magic occur.
For instance, try with this shellcode (chosen completely arbitrarily), and you should get something like this:
