Scemu - X86 32bits Emulator, For Securely Emulating Shellcodes

http://4.bp.blogspot.com/-N71EhQnNmmU/Yd0IiZNfNrI/AAAAAAAA7rE/Nvnbcz3-2Jc6ood3LxnZkR8sqOKAN2AyACK4BGAYYCw/w640-h590/scemu_6_msgbox-792923.png x86 32bits emulator, for securely emulating shellcodes. Features*

rust safety, good for malware.
* All dependencies are in rust.
* zero unsafe{} blocks.

*
very fast emulation (much faster than unicorn)

* 3,000,000 instructions/second
* 100,000 instructions/second printing every instruction -vv.

* powered by iced-x86 rust dissasembler awesome library.
* iteration detector.
* memory and register tracking.
* colorized.
* stop at specific moment and explore the state or modify it.
* 105 instructions implemented.
* 112 winapi implemented of 5 dlls.
* all linux syscalls.
* SEH chains.
* vectored exception handler.
* PEB, TEB structures.
* memory allocator.
* react with int3.
* non debugged cpuid.
* tests with known payloads:
* metasploit shellcodes.
* metasploit encoders.
* cobalt strike.
* shellgen.
* guloader (not totally for now, but arrive further than the debugger) TODO- more fpu
