Small Business Ransomware Defense Guide: Heuristics, Immutable Backups, and Zero Trust
Contrary to popular belief, small and medium-sized businesses (SMBs) are primary targets for modern Ransomware gangs. Clinics, legal practices, and local retailers handle high-value records but often operate without dedicated cybersecurity teams.
1. Common Attack Vectors
Cybercriminals consistently exploit exposed RDP ports, weaponized invoice attachments via spear-phishing, and unpatched operating system vulnerabilities to pivot laterally across the local corporate network.
2. The 3-2-1 Immutable Backup Rule
