Skullcode Disassembly Attempt

Notes

• initial.js is the initial javascript file referenced. It contains a large string of encrypted code and the code to decrypt it (and eval it).
• The decrypted code that is eval'ed by initial.js can be found in decrypted.js.
• The asm.js library code that is referenced in decrypted.js can be found in asm.js.
• Unfinished disassembly attempt of the code dumped from 0x400 to 0x65af can be found in disassembly.txt.
