Cyberattacks Against Small and Medium Businesses Nearly Double: What Chicago Business Owners Need to Know (September 2025 Update)

The numbers are in, and they're not good. A new report from cybersecurity company Guardz reveals that small and medium businesses faced nearly twice as many cyberattacks in the first half of 2025 compared to the same period in 2024. For Chicago business owners, this isn't just another scary headline: it's a wake-up call that demands immediate action.

If you've been thinking your Chicago-based business is "too small" to be a target, it's time to think again. The reality is that hackers don't care about your company size anymore. They care about easy targets, and unfortunately, many small and medium businesses fit that description perfectly.

What's Driving This Massive Surge in Attacks?

The explosion in cyberattacks isn't happening by accident. Three major factors are creating a perfect storm for small and medium businesses:

Attack-as-a-Service is booming. Cybercriminals can now rent sophisticated attack tools on the dark web, making it easier than ever for amateur hackers to launch professional-grade attacks. Think of it like Uber for cybercrime: you don't need to own the car (or know how to hack) to get where you want to go.

AI is making attacks smarter. Generative AI is helping criminals create more convincing phishing emails, fake websites, and social engineering campaigns. What used to take weeks of preparation can now be done in hours.

Remote work expanded the attack surface. With more Chicago businesses operating hybrid or remote models, there are simply more entry points for hackers to exploit. Every home office is a potential weak link in your security chain.

The Specific Threats Hitting Chicago Small and Medium Businesses Hard

Let's break down what Chicago business owners are actually facing right now:

Ransomware is the biggest threat. A staggering 82% of ransomware attacks target companies with fewer than 1,000 employees. Even more alarming? 37% of victims have fewer than 100 employees. This means your 20-person accounting firm or 50-employee manufacturing company is squarely in the crosshairs.

Password breaches are everywhere. Weak passwords and credential theft are behind most successful attacks. When one employee's password gets compromised, it can open the door to your entire network.

Phishing emails are getting scary good. Small and medium businesses receive the highest rate of targeted malicious emails: 1 in 323 emails is malicious. Your employees face 350% more social engineering attacks than workers at larger companies.

Cloud exploits are rising fast. As Chicago businesses move more operations to the cloud, hackers are following. Cloud misconfigurations and weak access controls are creating new vulnerabilities.

The Numbers That Should Keep Chicago Business Owners Awake at Night

Here are the statistics that matter most to your bottom line:

• 43% of all cyberattacks target small businesses

• 60% of small businesses that suffer a cyberattack shut down within six months

• 95% of cybersecurity incidents involve human error

• Small businesses typically spend between $826 and $653,587 per incident

• 87% of small businesses have customer data that could be compromised

That last stat is particularly important for Chicago businesses. Whether you're a law firm in the Loop, a medical practice in Lincoln Park, or a retail shop in Wicker Park, you likely have customer data that hackers want: and that you're legally required to protect.

Why Small and Medium Businesses Are Perfect Targets

From a hacker's perspective, small and medium businesses offer the perfect combination of valuable data and weak defenses. Here's their thinking:

You have money and data worth stealing. Contrary to popular belief, small businesses often have bank accounts worth targeting and customer databases worth selling.

You don't have enterprise-level security. While Fortune 500 companies have dedicated security teams, most small and medium businesses are making do with basic antivirus software and hoping for the best.

You're less likely to report attacks. Many small business owners worry that publicizing a breach will hurt their reputation, so attacks often go unreported.

You'll pay ransoms. When faced with losing everything, many small business owners choose to pay rather than risk permanent closure.

What Chicago Business Owners Must Do Right Now

The good news? You're not powerless against these threats. Here's what every Chicago small and medium business should implement immediately:

Start with the basics that actually work:

• Enable multi-factor authentication on everything: email, banking, cloud services, everything

• Use a business-grade password manager for your entire team

• Keep all software and systems updated (remember our recent Windows 11 warning?)

• Train your employees to spot phishing attempts

Think beyond the basics:

• Implement automated backups that are tested regularly

• Segment your network so one breach doesn't compromise everything

• Monitor your systems 24/7 (or partner with someone who does)

• Have an incident response plan ready before you need it

Get serious about employee training. Since 95% of incidents involve human error, your people are both your biggest risk and your best defense. Regular, practical training makes a huge difference.

The Chicago Advantage: Why Location Matters

Chicago's diverse business ecosystem creates unique opportunities and challenges. From healthcare practices dealing with HIPAA compliance to manufacturing companies protecting intellectual property, different industries face different risks.

The city's position as a transportation and financial hub also means Chicago businesses are increasingly attractive targets. Hackers know that disrupting Chicago commerce can have ripple effects across the entire Midwest economy.
