Ransomware and Small Business: What You Need to Know
Ransomware attacks on small businesses have surged. Here's what they are, how they happen, and what steps actually protect you.
Ransomware is malicious software that encrypts your files and demands payment for the decryption key. What was once a threat aimed primarily at large enterprises has become the dominant attack vector against small and medium businesses.
Why Small Businesses Are Prime Targets
Attackers have shifted focus to smaller organizations for three reasons: weaker security controls, faster payment decisions, and less law enforcement attention. A small business owner who depends on their systems to operate is far more likely to pay quickly than a large corporation with dedicated incident response teams.
How Ransomware Gets In
The vast majority of ransomware infections begin with one of three vectors:
- Phishing emails ... a malicious link or attachment that executes when clicked
- Compromised credentials ... password reuse or stolen login data gives attackers remote access
- Unpatched software ... known vulnerabilities in unupdated systems are exploited automatically
The Business Impact
The ransom payment is often the smallest cost. Add in: system downtime, recovery labor, potential data breach notification requirements, reputational damage, and the cost of hardening your systems afterward ... and a ransomware incident routinely costs 5-10x the ransom amount.
Protection That Actually Works
Three controls prevent the majority of ransomware incidents:
- Offline backups ... automated, tested, kept physically or logically separate from your main systems. Ransomware can't encrypt what it can't reach.
- Multi-factor authentication ... on every system with remote access. Stolen credentials can't open doors when a second factor is required.
- Email filtering and employee training ... block malicious attachments at the gateway and train staff to recognize phishing attempts.
None of these require enterprise budgets. They require consistent implementation and testing.
