# 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
```python
import angr
import claripy
import 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}
```
