# Shell Exploit
$ ./bin/badlang ../exploits/getshell/exploit.bad

• Reviewed community & research literature, added to README

• Started language specs
• Created 2 example exploits (pseudoscope, see BADLANG-drafting.md)
• More paper reading & discussion

• Created src/ directory with asmjit, basic makefile
• Add some debugging features to jit emitted code for ease of use
• Add examples/

• Refactored code and rewrote Makefile
• Created scanner and parser infrastructure for badlang
• Working "fizzbuzz" example

• Inserted "Dictionary" type into badlang, supporting "get", "set", and iteration through "forkey"
• Inserted "LeakJit" and "Jump" instructions
• Wrote several test programs, including one that leaks a pointer
• Made several quality-of-life improvements to the interpreter (ie the interpreter prints useful error messages instead of segfaulting)

• Made exploit script reliable by using internal AsmJit allocator instead of custom allocator.
• Began project writeup.
• Began project presentation.
