Doom Hacking

[amlwwalker]

This is cool. Used this to hack the Doom video game, youtube here: https://youtu.be/X5UHxr9TxvU

The code I used is:

#!/usr/bin/env python

import mach
import sys
if len(sys.argv) < 2:
  print "please specify a value to update the ammo to"
  sys.exit(1)

print "Writing " + sys.argv[1]
write=sys.argv[1].decode("hex")
task = mach.task_for_pid(int(5152))
value = mach.vm_read(task, 0xDD544, 2)#bytes
print "reading value: " + value.encode("hex")

write = mach.vm_write(task, 0xDD544, write)
print "successfully updated the ammo"
