What Is Phishing and How to Prevent It
Ransomware Explained: How Hackers Hold Data Hostage
Ransomware is a type of malicious software (malware) that locks or encrypts your data and demands payment (a ransom) to restore access. It's one of the most dangerous and costly cyber threats today.
🧨 How Ransomware Works
-

It starts with a phishing email, fake attachment, or malicious link.
-
One click can download the ransomware onto your device.

-
Encryption
-
The malware encrypts files, folders, or entire systems.
-
You can’t open, read, or use your data.
-
-
Ransom Demand
-
A message appears demanding payment, often in cryptocurrency.
-
Hackers promise to provide a decryption key if you pay.
-
-
