Last month, Foxconn had 8 terabytes of data stolen. West Pharmaceutical’s manufacturing operations went dark globally. Harvard University was breached. What do these attacks have in common?
In every case, attackers found a way in through a known, patchable vulnerability — not a clever phishing email, not a stolen password.
The Numbers Just Shifted — Dramatically
A new Verizon report confirms it: vulnerability exploitation is now the #1 way attackers breach organizations, surpassing stolen credentials for the first time in 19 years. Nearly a third of all breaches trace back to an unpatched or misconfigured system.
That’s a wake-up call. For years, the conventional wisdom was: “Worry about passwords. Phishing training. Good email hygiene.” All still matter. But the math has changed.
Why Now? AI Accelerates Everything — Including Attacks
Attackers are using AI to scan for vulnerabilities at scale, identify exposed systems in minutes, and exploit known flaws before patches are even applied. The window between vulnerability disclosure and active exploitation has shrunk from months to hours.
Meanwhile, most small and mid-sized businesses are still patching on a “when we get to it” schedule. That’s the gap threat actors are living in.
Your Vendors Are the Weakest Link — Again
Third-party breaches accounted for 48% of all breaches this year — up 60% from last year. If one of your software vendors has an exposed system, attackers will use that access to reach you. Supply chain risk isn’t abstract anymore. It’s on the evening news.
So What Actually Works?
- Patch management that runs automatically, not when someone remembers
- Continuous vulnerability scanning — not an annual audit
- Network segmentation so one exploited system doesn’t expose everything
- Backup and disaster recovery so you can survive an attack even when prevention fails
None of this is exotic. It’s disciplined IT management — the kind a managed IT partner handles while you focus on running your business.
