You might think the talk around artificial intelligence upending cybersecurity is just marketing noise. But the breach of over 600 FortiGate devices across 55 countries in early 2026 should convince you otherwise: the criminals are here, armed with AI, and they’re moving faster than your IT team wants to admit. This isn’t sci-fi. It’s happening while you finish your coffee.
FortiGate Owners, Meet Your New Automated Nightmare
The headlines say "Russian-speaking threat actor" but it's the AI angle that should really make you sit up. This wasn’t some genius-level operation exploiting some zero-day only three people understand. No, this was hype-free, brute practicality: scanning the open internet for management ports—443, 8443, 10443, 4443—on FortiGate devices dumb enough to expose them. Most of the work wasn't even clever. The criminals hammered away with common credentials, betting someone still hadn’t bothered to change that default admin password or set up anything beyond single-factor authentication.
Were you hoping that all this was out of your league? Sorry. These are the basics. And yet, basic security hygiene is missing at scale, everywhere from South Asia to Northern Europe and West Africa. That’s why the attack worked so well, with over 600 successful compromises. Forget about next-gen firewalls and AI-powered defense. If you’re leaving the front door unlocked, why bother with fancy new locks?
The Rise of AI as Cybercrime’s Partner in Crime
For years, we've been told that AI could help us spot threats, catch phishing attempts, and manage gigantic threat data lakes. That’s cute. Meanwhile, real-world hackers just started using commercial generative AI services to automate the boring (but effective) parts of their work. A threat actor with passable English and a pulse can now scale an attack far beyond what was possible even two years ago.
What did the AI do in this case? It built tools, spewed code, and planned attacks automatically. These weren't dazzling displays of software engineering, either. The code was full of redundant comments and looked like it had been churned out by someone new to development—or by an LLM faking it. But it didn’t matter. Simplicity is deadly when multiplied a few hundred times in a few weeks. The point is, AI didn’t need to simulate elite hackers. It just needed to speed up the grind: scanning, brute-forcing, moving laterally, pulling configuration data—rinse and repeat. More machines, less effort. That’s the automation story your vendors won’t stop selling you. Only now it’s on the other side.
From FortiGate to Total Network Exposure: The Domino Effect
Once attackers got in, the path was well-worn. They weren’t aiming for some arbitrary "lolz"; they wanted value. Here’s what they did:
- Harvested the entire device configuration. Conveniently, this meant grabbing admin credentials, all network blueprints, and whatever else the device coughs up. That’s free gold for any intruder.
- Hit Active Directory using DCSync, pulling full NTLM password hashes and effectively walking away with the corporate crown jewels.
- Used attack tactics like pass-the-hash and NTLM relays to bounce sideways across the network, scooping up access to more Windows hosts and, often, straight into backup systems.
- Targeted backup infrastructure—specifically Veeam servers—yanking credentials and exploiting old vulnerabilities, probably laying the groundwork for the kind of ransomware blast nobody wants to deal with on a Monday morning.
It’s a Swiss Army knife approach, enabled by simple, cheaply automated tools. There wasn’t even much sector selection; they grabbed whatever was easiest to reach. Some organizations got hit repeatedly, revealing that attackers do their homework once they spot a bigger payday, like a managed service provider looking after multiple networks.
Why Everyone Keeps Making the Same Dumb Mistakes
It's not that people haven't heard this stuff a hundred times: stop exposing management ports to the internet, change your default passwords, and use multi-factor authentication. Yet, here we are, years and hundreds of high-profile breaches later, still ignoring it. The breach didn’t require a genius. It required complacency. Ransomware gangs and financially motivated attackers know—most companies can't even get basic credential hygiene right.
Now add AI, and the equation doesn't get prettier. Attackers augmented with generative tools can target far more victims, more quickly, with less technical skill. This wave isn’t about brilliant new exploits; it's about scaling old exploits to a global level—automated scripts doing the drudgery attackers used to hate. You’re not being outsmarted, you’re being out-scaled.
Patching, Segmentation? Easy Advice, Hard Reality
If you've skimmed any security blog recently, the recommendations will sound familiar:
- Never expose management interfaces to the whole internet. This is security 101.
- Force everyone—yes, everyone—onto multi-factor authentication, especially admins and VPN users. Tired of hearing about it? Too bad, it works.
- Stop using those dumb default or reused passwords. Your attackers use lists in the millions and let AI do the guessing.
- Separate your backup servers so ransom-thirsty invaders can't trash your last lifeline easily.
- Keep all software patched. Stop pretending you’ll get to it “soon.” The bad guys don't wait for scheduled maintenance windows.
- Actually watch your networks for weird logins and unknown log sources. AI can help here, but apparently so can human laziness.
Organizations have the blueprint yet repeatedly trip on the first few steps. It’s almost impressive—if you squint and ignore the lost data, blackmailed companies, and endless insurance hikes.
The Harsh Reality of Today’s Hyper-Scale Cybercrime
AI-enhanced attacks are no longer theoretical. The FortiGate mass compromise incident is proof the barrier to entry has collapsed. From now on, expect more actors with less technical skill, wielding AI for everything from reconnaissance to scripting, pushing attacks into every corner of the internet. It won’t always be a nation-state with cutting-edge zero-days. Sometimes, it’ll be out-of-the-box AI tooling and a list of default passwords—and that’s all it’ll take to ruin your week.
The vigilance you need isn’t the sexy stuff peddled on conference stages. It starts with not being lazy about the basics. Because the other side? They’re not waiting for you to catch up.
