Ransomware

What is ransomware?

Ransomware is a type of malware (harmful software) that locks you out of your device or scrambles your files so you can't open them. Then it demands money - usually in the form of cryptocurrency - in exchange for a decryption key to unlock everything.

How does ransomware work?

• It is often delivered through fake or malicious e-mail attachments, compromised websites or infected apps.
• Once inside (installed), it locks your files, making them unusable. 
• A ransom message pops us, tell you to pay to get access to your files. Even if you pay, there's no guarantee your files will be restored. And paying could make you a target for future attacks.

What to do if infected

• Disconnect the infected device from all networks immediately to prevent further spread. Report the attack to Unisa.
• Don't pay the ransom. Restore your files from backups (if available).

Important tip! Always back up your files to ensure you can recover from an attack without needing to pay.
