AI can help criminals write more effective phishing emails, identify weak spots faster, and create more convincing fake voices for urgent requests. Manufacturing plants can reduce this risk by strengthening identity controls, separating IT from factory systems, locking down vendor access, and practicing recovery.
When AI-powered phishing, ransomware, or vendor account attacks hit manufacturing plants, downtime stops production, and missed shipments hurt customer trust.
Intelligent Technical Solutions (ITS) has spent over 20 years helping organizations, including manufacturers, protect their networks without shutting down production. We help you prevent attacks that cause downtime and protect your reputation.
In this article, we've invited Sean Harris, ITS Chief Risk and Compliance Officer, to share practical steps manufacturers can take to defend against AI-powered attacks.
You will learn:
- How can manufacturing plants reduce the risk of AI-driven phishing and payment fraud?
- How can MSSPs help protect manufacturing plants from AI-powered attacks?
Why Are AI-Powered Attacks a Growing Threat to Manufacturing Plants?
Manufacturing plants run on equipment that often can't be patched easily. Production schedules don't allow lengthy security updates. Remote vendor access creates necessary but risky entry points. These realities make manufacturing targets attractive to criminals.
In some cases, AI and automation can cut the time from targeting to action from days to hours by finding weak spots faster and attacking more targets at once.
These capabilities create three specific problems for manufacturers:
AI-Powered Phishing
AI tools write emails that sound natural. Criminals scan your website and LinkedIn to learn vendor names and project details. These emails often match your plant's normal style.
Deepfake voice tools can imitate a person's voice from short recordings, making urgent fraud calls more believable.
Fewer Obvious Warning Signs
Traditional phishing emails had clear red flags, such as spelling errors, awkward phrasing, and requests that didn't align with normal business processes. However, AI-generated attacks look professional and sound natural, so these old warning signs no longer help.
Faster Network Attacks
Automated scanning tools can probe many organizations quickly for exposed remote access and known vulnerabilities. Once a vulnerability is found, humans would then work to exploit the found vulnerabilities. Some attackers are starting to use AI to exploit vulnerabilities without the need for any human interaction. This translates into more criminals gaining unauthorized access to networks.
Once criminals are inside your office network, they look for a path into factory equipment. If the two are connected with nothing in between, they'll find it.
Strengthen Identity Controls
Start with multi-factor authentication (MFA) on email, VPN, remote desktop, and admin tools. MFA blocks many account takeovers even when passwords get stolen.
Give people only the permissions they need for their specific job. For example, finance staff shouldn't have access to factory controls, and machine operators shouldn't access financial systems.
For service accounts, store credentials in a password vault, restrict access to them, and monitor their use.
Stop Payment and Vendor Scams With Process Controls
Call back to verify any request for new bank details or payment changes. The FBI recommends confirming payment changes using a trusted phone number you already have on file.
Use a number from your vendor records, not the one in the suspicious email. This simple step can block many business email compromise (BEC) attacks.
Next, require two-person approval for wire transfers, ACH changes, and gift card requests. Also, set a rule that high-dollar payments can’t be changed at the last minute without a verified callback and a second approval.
Train Teams on Real Threats
Short monthly training sessions are more effective than annual courses. Keep it practical with real phishing examples from your industry and use test emails to coach people.
Make it easy to report suspicious messages, ideally with a single click. Then tailor training by role, since executives face different scams than shop floor supervisors.
"For years, we taught people to watch for bad grammar and clumsy phrasing. That advice is basically dead,” Sean said. The con is the same one humans have always run on each other; the tools just got better.
He then points out, “So stop telling your team to hunt for typos. Teach them to ask whether the request actually makes sense. A real vendor doesn't change their bank details over email on a Friday afternoon.”

Attack methods change fast, and most plants can't staff 24/7 monitoring.
Managed Security Service Providers (MSSPs) fill this gap by providing expert security teams and continuous monitoring that manufacturing plants need but can't build internally.
Here are five ways MSSPs help:
Security Monitoring That Catches Threats Early
A strong MSSP can monitor your IT environment around the clock. With the right scope, they can also watch key factory network signals. This helps catch unusual logins, suspicious network traffic, and risky vendor connections sooner.
Their security tools can flag scanning activity and abnormal traffic patterns. The MSSP team then validates the alerts and responds quickly to reduce downtime risk.
Network Design That Limits Attack Spread
MSSPs help separate your office IT from factory systems. They design security zones and controlled paths so that problems in the office network are less likely to reach production systems.
They also set traffic rules that allow only the connections you actually need. For access to factory systems, jump boxes replace direct logins.
As Sean notes, "Most plants run flat networks where everything talks to everything, because that's how they grew. Nobody designed it that way.”
"Think of a building with no interior fire doors. A fire in the break room reaches the server room because there's nothing in between. Segmentation just adds the doors. And you can usually put them in without shutting the plant down for weeks, no matter what people assume," he explains.
Patch Management for Old Factory Equipment
An MSSP tracks firmware versions, vendor security notices, and equipment nearing the end of life. They prioritize systems based on safety risk and production impact before recommending changes.
When a patch can be applied without disrupting operations, they roll it out during planned windows. When updates carry too much downtime risk, they use compensating controls such as tighter network separation.
Changes are tested first on non-critical equipment before wider deployment.
Backup Testing and Recovery Planning
MSSPs set up offline or locked backups that ransomware can't reach. They test these backups regularly to confirm that restores work.
You get separate recovery plans for office IT and factory systems, with clear decision points on when to isolate, when to shut down, and who makes calls.
Sean explains, "A backup you've never restored is a hope, not a plan. Most plants learn that the hard way, on the day they're actually down. It's not if you get hit, it's when. So test your restores on a schedule. You wouldn't buy car insurance and just assume it pays out. Same idea. You want to know it works before the fire, not during it."

Vendor Access Controls That Don't Slow Work
MSSPs create time-limited vendor access that expires after maintenance. Every vendor user needs MFA and has access only to what their job requires. Sessions are logged and reviewed so you can verify what happened and spot risky behavior.
For higher-risk vendors, many plants also add security requirements to the agreement.
Keep Your Plant Protected as AI Threats Evolve
AI-powered attacks can move faster and look more convincing than older threats. Manufacturing plants cannot afford to wait for an incident before strengthening defenses.
Since 2003, ITS has helped organizations, including manufacturers, reduce cyber risk and avoid costly downtime. As an MSSP, we build practical defenses for production networks while keeping operations moving.
