It is being loaded with a base address of 0x400000. WARNING | angr.state_plugins.symbolic_memory | The program is accessing memory or registers with an unspecified value. This could indicate unwanted behavior. WARNING | angr.state_plugins.symbolic_memory | angr will cope with this by generating an unconstrained …

Jan 24, 2022 · I would like to do the same thing under angr. I don't need any symbolic execution, I don't need any Symbion: Just simply use angr as an emulator (which it's more than capable of). How can I tell angr to run everything concretely, but still continue to hook the libs and replace them with angr's sims? Surprisingly, this turns out to not be simple.

Most angr solutions I have seen are based on a path that is taken if a certain condition is met. Given the address of that path, it is possible to solve the constraints required to get to the address of that path.

Apr 10, 2020 · In angr, there are multiple ways to print out what you want. You can reference functions or basic blocks. All you need to print out disassembly is an address:

Feb 26, 2021 · Using the call stack info, I want Angr's entry point to be a couple of levels up, still inside the plugin DLL (instead of starting at the default entry point of the main application, which I assume will generate way too many paths for Angr). I want Angr to find a path from there to the breakpoint. Here is where I become a bit confused.

Apr 5, 2022 · A simple problem I see in your code is. state.regs.rax = 0x100000 if you need to set constraint on a function argument - you 'll need to follow the calling convention.

Jan 15, 2019 · p = angr.Project("target_binary") state = p.factory.blank_state(addr=0x400770) I strongly recommend reading the State Presets section of the docs for more information. Crucially, all of the state preset constructors can take the addr argument; depending what you're doing, there may be a better preset to use than blank_state .

By the way, angr's CFG class is more than just the .graph member (which is a networkx.DiGraph instance). You might find it easier sometimes to directly work on CFG, instead of manually traversing the graph. In addition, once a CFG is generated, you can access all functions by accessing CFG.functions.

Angr will load PIE enabled elf at a base address of 0x400000, add this to your FIND address so that angr is able to resolve this. I have made a couple of changes to your script to make it detect the "password".

The constants used are different for each basic block. So, it seemed like a great target for angr! Attempts (using call_state): 1) Uses SimulationManager.explore; Drops avoid and deadended states after each step (using step_func) Runs of out memory after ~10 minutes (8GB) 2) Uses SimulationManager.step
