Ransomware Defined: How Does It Work & How to Prevent It

Ransomware is malware that encrypts your data. A private (and closely guarded) key can make your files readable once more. But hackers typically won't give you that key unless you give them something in return.

A ransomware attack is always serious, and some companies are prepared to pay anything to get their files back again. But you can close vulnerabilities that leave you open to attack. And if you are hacked, you'll need to take quick action to restore normalcy. 

What Is Ransomware?

You click and click and click, but you can't see your files. Instead, you see a threatening message that demands money.

What's happening?

You could be dealing with ransomware.

To execute an attack, hackers install malicious software into your system. All you'll see is a demand for money. Pay the fee, and you'll gain access again. 

Ransomware might involve:

  • A dark screen. You're tapping away on your files, and everything fades to black. All you can see is a demand for money or a set of instructions. 
  • Endless popups. Your device is flooded with windows containing messages, video, or pornography.Â
