# FooBar CTF 2022 - Matrix Master
## solution
this is slow and hard to solve it manually so we wrote a script using python and angr to solve it
```pythonimport angrimport claripyimport sys
proj = angr.Project("./matrix")state = proj.factory.entry_state()
simgr = proj.factory.simgr()simgr.run()
if simgr.deadended:    for s in simgr.deadended:        tmp = s.posix.dumps(0)        if b"glug" in tmp.lower():            print(tmp)
```
run it, we'll get the flag
```GLUG{EscaP3_7He_m@TRIx}```
