Why 43% of Cyberattacks Target Small Businesses (And How to Protect Yourself in 2024)
Sarah’s 16-person marketing agency thought they were “too small” to be targeted by cybercriminals. That changed when ransomware encrypted all their client files, demanding $35,000 for the decryption key. The attack lasted 12 days, cost $127,000 in total damages, and nearly destroyed her business. Here’s why attackers chose her company—and how to make sure yours isn’t next.
TL;DR: Small businesses face 43% of all cyberattacks despite representing only 27% of the workforce because they’re seen as easy targets with valuable data and weak defenses. This guide explains exactly why attackers target SMBs, reveals the real-world tactics they use, and provides a practical protection plan that 94% of attacks can’t defeat.
The Shocking Reality: Small Businesses Are Prime Targets
The Numbers Don’t Lie
2024 Small Business Cyber Attack Statistics:
- 43% of cyberattacks specifically target small businesses
- 61% of SMBs were hit by cyberattacks in 2023
- Only 14% of small businesses feel prepared to defend against cyberattacks
- 60% of small companies go out of business within 6 months of a major cyberattack
- Average attack cost: $200,000 for small businesses
- Detection time: 287 days on average for small businesses vs. 207 days for enterprises
Why These Numbers Are Getting Worse

Why Criminals Target Small Businesses: The Perfect Storm
Reason 1: Lower Security Investment = Easier Access

Reason 2: Valuable Data, Weaker Protection
What Small Businesses Have That Criminals Want:
- Customer data: Names, addresses, phone numbers, email addresses
- Financial information: Bank accounts, credit card data, tax records
- Business intelligence: Customer lists, pricing, strategic plans
- Access credentials: Passwords, API keys, system access
- Network access: Gateway to larger business partners and customers

Industry-Specific Protection Strategies
Healthcare Practices: HIPAA + Security
# Healthcare-Specific Protection Priorities
## Critical Controls (Beyond Standard Stack)
1. **HIPAA Risk Assessment** - Annual requirement, identifies specific vulnerabilities
2. **Business Associate Agreements** - All vendors handling PHI must sign BAAs
3. **Audit Logging** - Detailed logs of all PHI access and modifications
4. **Encryption** - PHI must be encrypted at rest and in transit
5. **Access Controls** - Role-based access, minimum necessary principle
## Common Healthcare Attack Vectors
- **Medical IoT Devices** - Often unpatched and insecure
- **EHR Systems** - High-value targets for identity theft
- **Insurance Billing** - Financial fraud opportunities
- **Patient Communications** - PHI exposure via unsecured email
## Protection Cost: $18-35/employee/month additional for HIPAA compliance
Legal Firms: Ethics + Security
# Legal Practice Protection Priorities
## Attorney Ethics Considerations
1. **Client Confidentiality** - Technology must preserve attorney-client privilege
2. **Conflict Checking** - Systems to prevent conflicts of interest
3. **Document Retention** - Meet court-mandated retention requirements
4. **Secure Communications** - Privileged communications must be protected
## Legal-Specific Attack Vectors
- **Trust Account Fraud** - BEC attacks targeting IOLTA accounts
- **Document Theft** - Opposing parties seeking privileged information
- **Client Impersonation** - Attackers posing as clients to gather intel
- **Court System Integration** - e-filing system vulnerabilities
## Protection Cost: $15-28/employee/month additional for legal compliance
Financial Services: SOX + PCI + Security
# Financial Services Protection Priorities
## Regulatory Requirements
1. **SOX Compliance** - Financial reporting system controls
2. **PCI DSS** - Payment card data protection standards
3. **GLBA** - Customer financial information safeguards
4. **State Banking Laws** - Additional regulatory requirements
## Financial-Specific Attack Vectors
- **Wire Transfer Fraud** - BEC attacks on payment systems
- **Customer Data Theft** - High-value personal financial information
- **Trading System Attacks** - Market manipulation attempts
- **Regulatory Reporting** - Attacks on compliance systems
## Protection Cost: $25-45/employee/month additional for financial compliance
