angr | populate int array with constraints - Reverse Engineering Stack . . . 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 symbolic variable and continuing
How to prevent angr from taking dozens of hours and GB of memory . . . 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
Proper workflow for x64dbg to Angr? - Reverse Engineering Stack Exchange 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
Basic `angr` framework question- is something wrong with my solver? I modified your script slightly to have a 20 character string, with every other byte null, ending in a newline, and angr successfully found the flag There are lots of other ways to do this with Angr, but this seemed close to how you were originally using it Modified Angr script:
Angr never finishes - Reverse Engineering Stack Exchange 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"
Start Symbolic Analysis at a Given Address with Angr 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
