43% of cyber attacks target small businesses. Only 14% are prepared to defend themselves. Here are the threats you need to know about and what to do about each one.
Attackers encrypt your files and demand payment to unlock them. Average ransom demand for SMBs: $150,000+. Average downtime: 22 days. Many businesses that pay never get their data back.
Defense: Maintain offline backups (3-2-1 rule), keep systems patched, train employees to recognize phishing, and segment your network.
Attackers impersonate executives or vendors to trick employees into sending money or sensitive data. BEC caused $2.9 billion in reported losses in 2024. These are targeted attacks, not mass spam.
Defense: Implement DMARC with reject policy, require verbal confirmation for financial transactions over a threshold, and use email authentication.
Attackers compromise your software vendors, MSPs, or business partners to gain access to your systems. One compromised vendor can expose thousands of businesses simultaneously.
Defense: Vet your vendors' security practices, limit third-party access to only what is necessary, and monitor for unusual activity from vendor accounts.
Attackers use stolen username/password combinations from data breaches to try logging into your business accounts. If your employees reuse passwords, this attack succeeds.
Defense: Enforce MFA on all business accounts, use a password manager, and monitor for compromised credentials on the dark web.
Current or former employees who misuse their access to steal data, sabotage systems, or sell credentials. Not always malicious, sometimes negligent employees accidentally expose data.
Defense: Implement least-privilege access, disable accounts immediately when employees leave, monitor for unusual data access patterns, and log all admin actions.
Smart devices (cameras, printers, thermostats) on your network often have weak security, default passwords, and no update mechanism. Attackers use them as entry points to your network.
Defense: Isolate IoT devices on a separate network segment, change default passwords, disable unnecessary features, and keep firmware updated.
Attackers use AI to create convincing phishing emails, deepfake voice calls, and automated vulnerability scanning. AI makes attacks faster, cheaper, and harder to detect.
Defense: Train employees on AI-generated content, implement email authentication to block spoofed messages, and use AI-powered security tools that fight fire with fire.
Misconfigured cloud storage (public S3 buckets, open databases, exposed APIs) is one of the leading causes of data breaches. Default settings in cloud platforms are often insecure.
Defense: Audit cloud configurations regularly, use cloud security posture management tools, follow the principle of least privilege for cloud access.
Known vulnerabilities in unpatched software are one of the easiest attack vectors. Attackers scan the internet for systems running outdated software and exploit known flaws automatically.
Defense: Implement automated patch management, maintain an inventory of all software, and prioritize patching internet-facing systems within 48 hours of critical patches.
Manipulating people into giving up information or access. Includes pretexting, vishing (voice phishing), SMS phishing, and physical social engineering. Technology alone cannot stop this.
Defense: Regular security awareness training, establish verification procedures for sensitive requests, create a culture where employees feel safe reporting suspicious activity.
