Ransomware is a type of malware that encrypts data and demands a ransom: crypto encrypts files, locker blocks systems, double extortion demands two payments, and Ransomware as a Service allows criminals to acquire malicious code for a fee. Ransomware often infiltrates organizations through phishing, credential abuse, and unpatched system vulnerabilities. Preventive measures include strong cybersecurity programs, employee education, regular system patching, and frequent backups. Once attacked, businesses must isolate the infected device, identify the ransomware type, remove the malware, and restore the system. Deciding whether to pay the ransom may depend on the speed of recovery, threat to business operations, cost of recovery, and data security.
