Browse our mini-guide to find out more about this cyber threat
Imagine waking up one day, turning on your computer and discovering that all your files are locked with a message demanding money to unlock them. This is not a scene from a film, but a very real threat called ransomware. Simply put, ransomware is a type of malicious software that prevents you from accessing your files and demands a ‘ransom’ to get them back. This mini-guide aims to explain the ransomware phenomenon in an easy-to-understand way, explaining what it is, how it works, and how you can protect yourself from it.
A digital kidnapper…
Ransomware is like a digital kidnapper. It sneaks onto your computer, locks your files, then demands money to release them. These attacks can be very damaging, resulting in the loss of important files and costing a lot of money. And just like in a real kidnapping, paying the ransom doesn’t always guarantee that you’ll get your files back.
Ransomware attacks can target anyone: from individuals at home, to large businesses, and even state organisations. The rise of digital money, such as Bitcoin, has made these attacks more common, as it allows hackers to pocket a ransom without betraying their identity.
The 3 main ransomware profiles
Ransomware comes in many forms, but the most common types are scareware, screen lockers and encryption ransomware.
- Scareware is like a digital swindler. It tricks you into thinking your computer is infected with viruses, then asks for money to fix the problem.
- Screen lockers act like digital sequestration. They lock your computer and display a message claiming you’ve done something illegal. To unlock your computer, you’ll be asked to pay a “fine”.
- Encryption ransomware is the most dangerous type. It’s like a digital safecracker. It locks your files in a digital safe, then demands money for the key to unlock the safe.
How does ransomware lock files?
Ransomware uses a method called encryption to lock your files. It’s like changing the language of your files to a secret code that only the ransomware knows. The most common method is symmetric encryption, where the same secret code is used to lock and unlock files. This secret code is created on your computer when the ransomware sneaks in, and then sent back to the cyber criminals’ computer.
