For years, the manufacturing sector operated under the "security through obscurity" model—relying on air-gapped systems and proprietary protocols to stay off the radar of mainstream cybercriminals. According to the Huntress 2026 Cyber Threat Report, those days are officially over.
Manufacturing has emerged as one of the most targeted industries, not necessarily because its data is the most valuable, but because its tolerance for downtime is the lowest. In an industry where "minutes equal millions," attackers are shifting their tactics from simple data theft to sophisticated operational paralysis.
The report highlights a staggering shift: attackers have realized they don't need to find a zero-day exploit when they can simply steal a credential. In manufacturing, where remote access for vendors and technicians is a necessity, identity-based attacks have surged. And a recent blog post dives further into the woes manufacturers face from a cybersecurity standpoint.
What it means: CISOs must move beyond traditional MFA. Attackers are now using MFA fatigue and token theft to bypass legacy defenses. For a manufacturing firm, a single compromised service account used for equipment maintenance can provide an attacker with lateral access to the entire Production VLAN.
One of the most unsettling trends in the 2026 report is the heavy abuse of Remote Monitoring and Management (RMM) tools. Attackers are "living off the land," using the very software your IT team uses to manage the environment to instead deploy ransomware or exfiltrate IP.
What it means: Security teams can no longer assume that "authorized software" is performing "authorized actions." Detecting these threats requires behavioral analysis that can distinguish between a technician performing a routine update and an adversary using that same tool to disable security agents.
Ransomware remains the apex predator for manufacturing. However, the report notes a shift toward exfiltration-only attacks and lock-and-leak tactics. Attackers are increasingly targeting the "crown jewels" of manufacturing: proprietary CAD files, sensitive formulas, and supply chain contracts.
What it means: Even if your backups are "gold-plated" and you can restore systems in hours, the threat of data exposure remains a powerful lever for extortion. Defense strategies must prioritize Data Loss Prevention (DLP) and egress filtering just as much as rapid recovery.
From the blog post: "Threat actors have figured out that while you might be able to live without your data for a few days, you can't survive with a dead assembly line. They're moving past the office network to disrupt the operational technology (OT) systems that keep your machines running.
While the exact cost changes based on what you're making, the ripple effects are the same across the board:
-
Missed shipments: Late deliveries trigger contract penalties and upset your biggest partners.
-
Idle labor: You're still paying for staff and overhead, even if no one can do their job.
-
Restart pains: Getting an OT system back online safely takes much longer than a standard IT reboot.
-
Safety risks: Sudden shutdowns can damage sensitive equipment or create hazardous conditions for people on the floor or in the plants."
The 2026 landscape demands a transition from "security as a cost center" to "resilience as a business continuity strategy," the researchers urge. Some tips from the report and blog post:
-
Audit "shadow" integrations: Manufacturers often have a sprawling web of SaaS and cloud-native integrations that create an invisible attack surface. Securing these "fragmented identities" is now the mandate for survival.
-
Bridge the IT/OT gap: As digital convergence accelerates, the air gap is a myth. Security teams need unified visibility that covers both the corporate office and the PLC (Programmable Logic Controller) on the floor.
-
Prepare for AI-speed social engineering: The report warns of a 14x increase in AI-generated phishing. Manufacturing help desks—often the primary point for password resets and vendor onboarding—must be trained to identify synthetic audio and hyper-personalized impersonation attempts.
More from the blog post around control and governance:
-
"Between government programs and directives like CMMC 2.0 and NIS2, and big customers demanding proof of security before they sign a contract, the pressure is on."
-
"Governance is about making sure that cybersecurity programs are fit-for-purpose, well-managed, and compliant, so that if a threat actor does find a way in, you have a practical plan to stop them. Regulators and partners want to see that you aren't just guessing—they want to see that you have a handle on who has access to your systems, apps, and data, and what's running on your floor."
As the blog points out, Zero Trust has finally hit the factory floor.
"Zero Trust architecture can feel like a lot to ask of an organization and its employees," said Brian Milbier, Senior Director of Security and IT and Deputy CISO at Huntress. "But, what it's really about is ensuring that every system at every level is protected and that no one is able to gain unauthorized access."
