Ransomware is a type of malicious software, or malware, that tries to hold your computer files hostage. The ransomware gets into your computer without you knowing, usually through a link or attachment in an email or online. Once it’s inside, it encrypts all your important files like photos, documents, and other data. This means it locks and scrambles the files so you can’t open or access them anymore. Then, a message will pop up on your screen demanding money, often paid in bitcoin, in order to get the key to unlock your files again. The malware threatens that you’ll never get your files back if you don’t pay.
If ransomware infects your computer, it’s important to act fast. Don’t panic, and don’t pay the ransom right away. First, disconnect your computer from the internet and don’t use it until you get expert help. They may be able to help identify the ransomware and find a way to unlock your files without paying criminals. You should also contact your local police to file a report if they have any other advice. Most of all, don’t give in to the ransomware scammers, as there is no guarantee they will actually unlock your files even if you pay. The best defense is being very careful about what files and links you open to avoid this type of ransomware attack in the first place.
Understanding Ransomware
What is Ransomware?
Ransomware is a type of malicious software designed to block access to your computer system or files until a sum of money is paid. It works by encrypting your data, making it unreadable without a decryption key. The attackers then demand a ransom in exchange for this key.
You might encounter various types of ransomware, including:
- Crypto ransomware: Encrypts files on your device
- Locker ransomware: Locks you out of your entire system
- Scareware: Tricks you into thinking you’re infected and need to pay to remove the “threat”
- Doxware: Threatens to publish your personal information online
Understanding the type of ransomware you’re dealing with can help you respond more effectively to the attack.
