The Top 5 Cybersecurity Threats Facing Small Businesses in 2025

Cyber threats are evolving faster than ever, and small businesses are no longer flying under the radar. In fact, according to Verizon’s 2024 Data Breach Investigations Report, 61% of data breaches now target businesses with fewer than 1,000 employees.

If you run or manage a small business, understanding where the threats are coming from in 2025 could save you from costly downtime, legal trouble, or worse—losing your customers' trust.

Here are the top five threats you should be paying attention to right now:

1. Phishing & Business Email Compromise (BEC)

Phishing is still the most common way hackers get in—and they’re getting smarter about it.

What’s new in 2025:

• AI-generated phishing emails are harder to detect, with personalized details and natural-sounding language.
• BEC attacks have surged, where attackers pose as executives to trick employees into wiring funds or sharing login info.

Stat: The FBI's IC3 reported $2.9 billion in BEC-related losses in 2023—up nearly 15% year-over-year.

Action tip: Train your team to recognize red flags, use email filters, and enable two-factor authentication on all business accounts.

2. Ransomware Targeting Supply Chains

Ransomware is no longer just about locking your files—it’s about disrupting entire business ecosystems.

What's happening:

• Hackers now target small vendors to get access to larger networks (a tactic known as island hopping).
• Ransom demands are growing, with attackers threatening to leak sensitive data if not paid.

Stat: According to Sophos’ 2024 report, 66% of SMBs hit by ransomware paid at least some portion of the ransom—but only 57% fully recovered their data.

Action tip: Back up your data regularly, offline and in the cloud. Run simulations to test your ransomware response plan.

3. Unsecured Remote Access and BYOD Devices

The rise of hybrid work means more devices, more access points, and more risk.

In 2025:

• Many businesses are still relying on personal devices (BYOD) and unsecured home networks.
• Remote desktop protocol (RDP) attacks are resurging, with brute-force attempts up 35% in Q1 2025 alone.

Stat: A 2025 Cisco report found that 54% of SMBs had no formal mobile device management policy in place.

Action tip: Use VPNs, require encrypted access, and invest in endpoint protection for all devices connecting to your network.

4. AI-Enhanced Social Engineering

AI isn't just helping the good guys. Hackers are now using AI to craft more believable scams, clone voices, and even deepfake video messages.

Real-world risk:

• A CEO's voice cloned from public webinars used to trick a CFO into transferring funds.
• Deepfakes used in internal Slack channels or Zoom meetings to impersonate staff.

Stat: Gartner predicts that by the end of 2025, 30% of all successful social engineering attacks will involve AI-generated content.

Action tip: Use internal verification protocols (e.g., call-back confirmations) for sensitive requests. Train staff to detect manipulated media.

5. Outdated Software and Weak Patch Management

Too many businesses still rely on outdated systems—making them a prime target for automated scanning bots.

The risk:

• Common platforms like WordPress, Shopify, and outdated CRMs often have unpatched vulnerabilities.
• Attackers now use AI tools to find and exploit these gaps faster than ever.

Stat: A recent report from Check Point Software found that 38% of attacks on small businesses in 2024 exploited known vulnerabilities with available patches.

Action tip: Automate your updates where possible. Run regular vulnerability scans and remove unused plugins and tools.

Small Businesses Are Big Targets

You don’t need to be a Fortune 500 company to be a target anymore. Hackers follow the path of least resistance—and unfortunately, small businesses are often that path.

The good news? Most cyberattacks are preventable with the right awareness and a proactive security plan.
