Phishing used to be easy to spot — awkward grammar, a suspicious link, a sender name that didn't quite match. That's changing fast. Attackers are now using generative AI to write flawless, personalized emails that reference real vendors, real coworkers, and real ongoing projects at your company. For small and mid-sized businesses in Columbus, this shift means the old "look for typos" training no longer cuts it.
Why AI Changed the Game
Generative AI tools let attackers scrape publicly available information — LinkedIn profiles, press releases, even your own website's staff page — and turn it into a convincing, context-aware email in seconds. A message that appears to come from your CFO asking accounting to rush a wire transfer, written in a tone that matches how your CFO actually writes, is no longer science fiction. It's a Tuesday.
What This Looks Like in Practice
- Vendor impersonation: An email mimicking a supplier you actually work with, requesting updated banking details.
- Executive impersonation: A message that sounds exactly like a request from ownership or leadership, pressuring urgency.
- Voice and video deepfakes: Increasingly used alongside email to "confirm" a fraudulent request over a call.
- Malicious AI chatbot links: Fake "internal tool" or "HR portal" links designed to harvest credentials.
The uncomfortable truth
Spam filters catch known threats. They don't reliably catch a brand-new, AI-generated email that has never been seen before — because there's no signature to match against yet.
How Columbus Businesses Can Defend Against This
You don't need a Fortune 500 security budget to close this gap. The businesses we work with across Columbus, Westerville, and the surrounding area see the biggest improvement from a layered approach:
- Modern email filtering that uses behavioral analysis, not just known-threat databases.
- Verification protocols for any request involving money or credentials — a callback to a known number, not a reply to the email itself.
- Ongoing employee training that reflects current AI-driven tactics, not a once-a-year slideshow.
- Multi-factor authentication everywhere it can go, so a stolen password alone isn't enough.
- An incident response plan your team actually knows, so the first 30 minutes after a click aren't spent panicking.
Where to Start
If it's been more than a year since your team's last security awareness training, or you're not sure whether your current email filtering can catch a well-written, targeted message, that's the place to start. An IT risk assessment gives you a clear, prioritized picture of where you're exposed — before an attacker finds it for you.
