Ransomware is a malicious program. It can infect a single computer or a network of computers, encrypting the data, making it inaccessible. Upon infection, the cybercriminals communicate their demands, often a ransom that must be paid in order to decrypt the data.
According to one survey, 98% of attackers provided an encryption tool upon payment.3
Considering the costs, you want to avoid this situation entirely, which you can do with solid network and endpoint protection, employee training, and a well-defined disaster recovery plan.
