angrdbg

Abstract library to generate angr states from a debugger state

Install

pip install angrdbg

The library uses an abstract class, Debugger, to be agnostic from the debugger api.

The user must implement a derived class, see abstract_debugger.py to view the methods that must be implemented.

After this register an instance of the derived class with the register_debugger function.

To create an angr state from the current debugger state use StateShot.

Return an angr state from the current debug session state.

A wrapper around angr to simplify the symbolic values creation and to write the results back in the debugger when angr founds a valid path.

instance.sim(key, size) create a symbolic value on a register or on a memory address (size is optional)
instance[key] get a register or a memory value
instance.simulation_manager() create an angr simulation manager based on the state
instance.to_dbg(found_state) transfer to the debugger state the evaluated value of the symbolic value created before with sim

note: memory values are the same that are returned by state.mem[addr]

The memory type defines how angrdbg get the memory from the debugger and from the cle backer. Use get_memory_type to know what the active one.

You can change the memory type with set_memory_type.

SIMPROCS_FROM_CLE import only not-stubs simprocedures in the got from the cle backer (defaut)
ONLY_GOT_FROM_CLE import the entire got from the cle backer
USE_CLE_MEMORY import memory from the cle backer firstly
GET_ALL_DISCARD_CLE full debugger memory mode (the only avaiable for PE at the moment)
