THE RANSOM IS ONE NUMBER. EVERY DAY YOUR LINES SIT STILL IS ANOTHER.
It's 6 a.m. on a Monday. First shift is on the floor, but the MES won't load. Scheduling can't see today's orders. Shipping can't print a bill of lading, and two trucks are already backed up to the dock. By 6:30, someone from the front office walks out to find the plant manager. Every screen upstairs is showing the same message.
At a plant, ransomware shows up as a production problem first. And it gets more expensive every hour the lines don't run.
Most manufacturing leaders have some idea what a ransom demand looks like. Far fewer have ever put a number on what a day of downtime costs them. That second number is the one that decides how bad an attack gets.
Manufacturing is the most-targeted industry for ransomware, and attacks are climbing. Black Kite's 2026 Ransomware Report found manufacturing "held the top spot again, with 1,660 victims and 22.0% of all disclosures" between April 2025 and March 2026.
This year is running hotter. The same research group's 2026 Manufacturing & Distribution Ransomware Report counted 1,183 manufacturing incidents from January through July 2026, a 39.7% increase over the same stretch in 2025.
The victims aren't household names, either. Among manufacturers hit this year whose revenue was known, 70.2% brought in between $10 million and $100 million. The median victim made $42.9 million a year. That's a mid-size plant, the kind you'd find in any Iowa industrial park.
Anywhere from a few days to more than a month. In Sophos's survey of 332 manufacturers hit by ransomware, published in December 2025, 58% fully recovered within one week. That leaves 42% who needed longer.
Recent attacks show what "longer" looks like:
fairlife (dairy manufacturing), July 2026. Coca-Cola disclosed in an SEC filing on July 16 that fairlife's U.S. production was temporarily suspended after a ransomware event reached production-related systems. On July 27, eleven days later, the company announced the majority of production had resumed at its four facilities.
Boston Scientific (medical devices), August 2026. The company identified a cybersecurity incident on August 25 that its SEC filing described as "a global disruption" to its ability to process and ship customer orders. MD+DI reported on September 11 that manufacturing, order fulfillment, and shipping were fully restored.
Jaguar Land Rover (automotive), September 2025. An attack detected on September 1 halted production for about five weeks. According to City AM's reporting on the UK's Cyber Monitoring Centre, only partial operations resumed in October, and full recovery wasn't expected until January 2026.
The day the systems come back also isn't the day the cost stops. Backlogs, missed ship dates, and overtime to catch up keep running the bill for weeks after.
More than most plants have budgeted for. Sophos found that manufacturers spent an average of $1.3 million to recover from a ransomware attack, not counting any ransom paid. What downtime costs your plant depends on what an hour of lost production is worth to you, and a lot of manufacturers have never worked that out.
For a sense of scale, Siemens' True Cost of Downtime 2024 report puts an hour of unplanned downtime at $36,000 for the world's largest consumer goods manufacturers and $2.3 million for the largest automakers. A mid-size plant will usually land well below those numbers. It also has thinner margins and less cash to absorb a bad month.
The cost of an outage usually comes from four places:
Lost output. Every hour the line sits still is product you can't ship or bill for.
Idle labor. Crews still get paid while they wait for systems to come back.
Missed shipments. Late orders mean expedited freight, contract penalties, or a customer who starts calling your competitor.
Recovery. Incident response, rebuilding systems, and the overtime it takes to work through the backlog.
At the far end of the scale, the Cyber Monitoring Centre estimated the Jaguar Land Rover attack cost the UK economy £1.9 billion and affected roughly 5,000 organizations. Its chair, Ciaran Martin, called it "by some distance, the single most financially damaging cyber event ever to hit the UK."

Because a plant can't work around its systems for long. When the ERP, MES, scheduling, or shipping systems go down, production usually goes down with them. And many manufacturers run too lean on inventory to ride out a long outage.
fairlife is a good example of the difference inventory makes. Coca-Cola said retail availability stayed "largely unimpacted, due to the availability of existing inventory" during its eleven-day shutdown. Most plants running just-in-time don't have that cushion.
You also don't have to be the one attacked. When Jaguar Land Rover went down, suppliers across Europe had to scale back or pause their own production, and the UK government stepped in with a £1.5 billion loan guarantee to help ease the pressure on its supply chain. If a major customer of yours gets hit, their downtime can become yours.
More and more, they log in with stolen passwords. Black Kite found the share of manufacturing ransomware victims with stolen credentials in circulation at the time the attack was disclosed climbed from 25.0% in 2023 to 41.8% in 2026.
Those passwords usually come from infostealer malware on an employee or contractor laptop. In Black Kite's words, "credentials leak continuously through infostealer infections on employee and contractor devices, and no patch cycle drains that pool." Even among manufacturers with more than $1 billion in revenue, 69.1% have employee or system credentials circulating in those markets.
Industrial Cyber reported that the group behind the Jaguar Land Rover attack allegedly got in through social engineering and stolen credentials. And AI is making this kind of attack cheaper to run. We covered that side of the story in It Costs $4 to Attack Your Business. It Takes Weeks to Recover.
Decide ahead of time what "recovered" means for each system, then prove you can get there. The plants that come back fastest are usually the ones that planned the order of recovery before they needed it.
Put a dollar figure on an hour of downtime. It's much easier to justify backups, monitoring, and testing when everyone in the room knows what the alternative costs.
Rank your systems by how fast they need to come back. Your MES and shipping systems might need to be back in hours. Other systems can wait days. That ranking becomes your recovery plan.
Test your restores. Having a backup and restoring from one are two different things. Run the test on a quiet weekend, not the morning after an attack.
Keep the plant floor separate from the office network. Separating production systems from email and office traffic limits how far an attack can spread.
Close the easy doors. Multi-factor authentication on anything people log into from outside the building, dark web monitoring for stolen company credentials, and security awareness training so your team can spot the phishing emails that plant infostealers in the first place.
Have someone watching around the clock. Attacks don't wait for first shift. Through our partnership with Arctic Wolf, high and critical alerts trigger an immediate call to a Koltiv technician, day or night.
Yes. Among manufacturers hit by ransomware in 2026 whose revenue was known, 70.2% brought in between $10 million and $100 million, according to Black Kite. The median victim made $42.9 million a year.
It ranges from a few days to more than a month. Sophos found 58% of manufacturers hit by ransomware fully recovered within a week, while 42% needed longer. Recent attacks have shut down production for eleven days (fairlife) and about five weeks (Jaguar Land Rover).
Sophos found manufacturers spent an average of $1.3 million recovering from a ransomware attack, not counting any ransom. Lost production, idle labor, and missed shipments come on top of that, and they depend on what an hour of downtime is worth to your plant.
Start with what an hour of lost production is worth, then add idle labor, missed or expedited shipments, and recovery costs. Koltiv's Manufacturing Downtime Calculator walks through wages, headcount, revenue, and recovery costs to estimate your hourly loss. ⬅ LINK (downtime calculator landing page)
That's a decision for your leadership, legal counsel, cyber insurer, and law enforcement to make together. Sophos found 51% of manufacturers hit by ransomware paid, with a median payment of $1 million. Paying doesn't guarantee a clean recovery, and the stronger position is being able to restore without it.
You don't need to build a security department to cut your downtime risk. You need a clear picture of what an outage would cost, a recovery plan you've tested, and someone watching when your team isn't.
We work with manufacturers across Iowa and the Midwest on exactly that, from cybersecurity risk assessments and disaster recovery planning to 24/7 managed detection and response. Our ARMOR and FORTRESS managed IT packages include MDR, dark web monitoring, security awareness training, and data loss prevention for Microsoft 365.
You know your floor. We know what it takes to keep the systems behind it running. And if it turns out you're in better shape than you thought, we'll tell you that too.
Most plants know their cost per part. Far fewer know their cost per hour of downtime. Getting that number, and a plan to keep it small, is one of the most useful things a manufacturing leader can do this quarter.
October is Manufacturing Month in Iowa, which makes it a good time to ask the questions nobody enjoys: what happens if the MES goes dark on a Monday morning, how long could you ship without it, and who's watching the network at 2 a.m.? If you'd rather work through those answers with someone, give us a call. We've been helping Midwest manufacturers keep their lines running for a long time, and we're happy to help you get your number.
