In 2023, the average ransomware demand soared to $233,817. Businesses worldwide suffered over $20 billion in losses — a 225% increase from the previous year.
In 2021, a ransomware attack occurred every 11 seconds — and today that gap is even smaller.
Your files are locked, your screen displays a ransom note, and a ticking clock demands cryptocurrency payment. This is ransomware — and it’s one of the fastest-growing cyber threats.

Key characteristics of ransomware attacks:
-
Data encryption locks access to important files.
