• Did you pay money as a victim of an attack?

Cybersecurity experts have warned businesses against meeting hackers' demands for money in the wake of the "unprecedented" attack on hundreds of thousands of computer systems around the world.

Ransomware is a type of malicious software that blocks access to a computer or its data and demands money to release it. The worm used in Friday's attack, dubbed WannaCry or WanaCrypt0r, encrypted more than 200,000 computers in more than 150 countries for ransoms of $300 to $600 to restore access.
