Ransomware

Overview

Ransomware has evolved into one of the most profitable and damaging cybercrimes. Modern ransomware often combines encryption with data exfiltration, threatening to leak sensitive information if ransom isn't paid (double extortion). Attacks typically begin with phishing emails, exploited vulnerabilities, or compromised credentials. Ransomware gangs operate as businesses, offering 'customer support' and negotiation services. The impact extends beyond ransom payments - downtime, recovery costs, reputational damage, and regulatory penalties can be devastating. Prevention requires comprehensive security: email filtering, endpoint protection, network segmentation, backups, and employee training.
