What is Ransomware?
Ransomware is a type of malicious software (malware) that encrypts your files or locks your device, rendering it unusable until you pay a ransom—usually in cryptocurrency like Bitcoin. Cybercriminals use ransomware to extort money, often threatening to delete your data or leak sensitive information if you don’t comply. It’s like a digital hostage situation, and it can target anyone from individual users to large organizations. Common ransomware variants include WannaCry, Ryuk, and LockBit, each with its own tactics but the same goal: to exploit and profit.
How Ransomware Works
Ransomware typically spreads through phishing emails, malicious downloads, or vulnerabilities in outdated software. Once it infects a system, it encrypts files using complex algorithms, making them inaccessible without a decryption key. The attacker then demands payment, often providing a countdown timer to add pressure. Even if you pay, there’s no guarantee you’ll get your files back—some victims lose both their money and data. Understanding this process is key to preventing attacks, which is where our 10 tools come in.
