October is Cybersecurity Awareness Month, and this year’s theme is simple: “Don’t Make It Easy for Them.”
Most business owners hear that and think of the usual suspects: weak passwords, missing MFA, out-of-date software. All still true. But right now, one of the easiest ways for your company’s data to end up in the wrong hands is something most leaders don’t even know is happening.
It’s called shadow AI. And it’s probably already in your business.
This Month’s Watchdog Warning: Shadow AI
Shadow AI is any AI tool your employees use that the business never approved. Think ChatGPT on a personal account, free AI browser extensions, AI note-takers that join meetings, and “summarize this PDF” websites.
These tools are fast, free, and genuinely useful. That’s exactly why they spread.
The problem is what goes into them. Every client list, contract, or financial report pasted into an unapproved AI tool leaves your control. You don’t know where it’s stored, who can see it, or whether it’s being used to train someone else’s model.
And the accounts themselves are often an open door. Personal logins tend to use weak or reused passwords with no MFA. Free browser extensions are rarely updated, and many request broad access to everything you see in your browser.
The numbers back it up. IBM’s 2026 Cost of a Data Breach Report found shadow AI was involved in 43% of the breaches studied, up from 20% a year earlier, at an average cost of $5.39 million per incident.
Why We’re at Threat Level 4: High
Three factors drive this month’s rating:
1. AI adoption is running far ahead of AI governance.
According to IBM, 68% of breached organizations had no AI governance policy. Among those hit by AI-related incidents, 92% lacked proper AI access controls.
2. Attackers are using AI too.
AI-driven attacks rose 56% last year, led by deepfakes, impersonation, and AI-written phishing. These messages are cleaner, more convincing, and harder to spot than the typo-filled scams employees were trained to catch.
3. The cost of getting it wrong keeps climbing.
The average U.S. data breach now costs $11.5 million. For a small or midsize business, even a fraction of that can be devastating.
So why not “Critical”? Because the basics still work. Strong passwords, MFA, staff awareness, and up-to-date software stop a huge share of these attacks. That’s the whole point of this year’s theme: don’t make it easy for them.
What We’re Hearing: “We Don’t Really Use It”
In almost every environment we walk into, AI is already in use. In most cases, no one has validated it or approved it, and leadership often doesn’t know it’s there.
When we ask business leaders how their team uses AI, the most common answer is “we don’t really use it.” Then we look, and it’s everywhere. Here’s what we typically find:
- Employees are self-deploying. Staff sign up for AI tools on their own using personal or work email. They install AI browser extensions, connect AI apps to company email, calendars, and file shares, and invite AI note-takers to meetings. IT is never involved.
- No one is validating it. Nobody has checked where the data goes, whether it’s stored or used for training, who the vendor is, or whether the account has MFA. Many of these tools get broad access to mailboxes and SharePoint with a single “Allow” click.
- Leadership doesn’t have visibility. Owners assume that if they didn’t buy it, it isn’t being used. There’s usually no AI policy, no approved tool list, and no one assigned to own it, so these decisions get made one employee at a time.
To be clear, this isn’t about bad intent. These are good employees trying to work faster. But the business is carrying risk it never agreed to take on, and it often can’t see that risk until something goes wrong.
Ears Up: Apply the Four Habits to AI
Cybersecurity Awareness Month is built around four core habits. This month, Bent Ear recommends taking each one and applying it directly to AI:
- Strong passwords & a password manager: AI tools get company-managed accounts, not personal logins.
- Turn on MFA: Every approved AI tool sits behind MFA and single sign-on.
- Recognize & report scams: Train staff on AI-powered phishing, voice cloning, and deepfake “CEO” requests.
- Update your software: Audit and remove unapproved AI browser extensions and apps.
Then put it all in writing. A one-page AI acceptable-use policy gives your team clear rules. Pair it with an approved AI tool so employees don’t go looking for their own.
Why not just ban AI?
Because banning AI doesn’t work. People just use it out of sight. Clear rules plus a safe, approved option turn hidden risk into managed productivity.
There’s a compliance angle, too. Cyber insurers and regulators, including NYDFS, FINRA, and HIPAA, are starting to ask about AI governance. Getting ahead of it now protects both your data and your coverage.
Cyber Health Check
Ask yourself:
Are you making it easy for them? Do you know which AI tools your employees used this week, and what company data went into them?
If you can’t answer that with confidence, you have a visibility gap worth closing now.
Mike’s Take
“Attackers love easy. An unapproved AI tool with a personal login and no MFA is about as easy as it gets. Your team is already using AI, so the real question is whether you’re managing it.”
The Myth: “We Don’t Use AI Here.”
Yes, you do. You just don’t know where.
AI is built into the browsers, meeting platforms, and productivity apps your team uses every day. Even if the business never bought a single AI tool, odds are your employees have already found their own.
The goal isn’t to stop AI. It’s to see it, approve it, and secure it, so you’re not handing attackers the easy way in.
How Exposed Is Your Business?
Shadow AI is just one place risk hides. Real cybersecurity is about how your people, devices, policies, and security controls work together when an attack actually reaches them.
Bent Ear’s Cyber Risk Score Assessment can help identify gaps across your current cybersecurity posture and give your business a clearer picture of where risk may be hiding, including the AI tools you didn’t know you had.
