Somewhere in America, a driver convicted of a DUI offense walked to their car, blew into a court-mandated ignition interlock device, and got no response. Not because they’d been drinking. Because hackers had taken down the company that makes the device.
Draeger, the German manufacturer of safety and medical technology — including the breathalyzer-style interlock systems installed in vehicles of DUI offenders — suffered a cyberattack that disrupted its operations and left an unknown number of drivers unable to start their cars. The attack, first reported by Wired, underscores a deeply uncomfortable reality: critical components of the criminal justice system now depend on networked technology that can be knocked offline by a single well-placed intrusion.
The incident is not just a cybersecurity story. It’s a story about what happens when public safety obligations — the kind imposed by courts — are outsourced to private companies whose digital infrastructure can fail in ways nobody anticipated when the sentence was handed down.
Ignition interlock devices are straightforward in concept. A driver blows into a mouthpiece. The device measures blood alcohol content. If the reading is below a preset threshold, the car starts. If not, it doesn’t. Courts across the United States order their installation for DUI offenders as a condition of retaining or regaining driving privileges. Millions of Americans have used them. The devices require periodic calibration and data uploads to monitoring authorities, which means they are connected — directly or indirectly — to company servers.
That connectivity became a liability.
Draeger confirmed the cyberattack but provided limited details about its scope or the specific systems affected. The company, headquartered in Lübeck, Germany, operates globally and produces equipment ranging from hospital ventilators to gas detection systems for industrial use. Its interlock division is one part of a sprawling operation. But for the drivers who depend on these devices to legally operate their vehicles, the disruption was immediate and tangible. Reports surfaced of people stranded — unable to get to work, medical appointments, or childcare obligations — because the device in their car couldn’t communicate with Draeger’s servers.
And here’s the part that should unsettle anyone thinking about the intersection of technology and justice: these drivers had no recourse. They couldn’t call a judge. They couldn’t bypass the device without risking a violation of their court order. They were, in effect, punished a second time — not for any action of their own, but because a company in Germany got hacked.
The broader cybersecurity context makes this incident more alarming, not less. As Wired noted in its weekly security roundup, the Draeger attack arrived during a period of intensifying cyber threats against infrastructure providers of all kinds. Ransomware gangs and state-affiliated hacking groups have expanded their target lists well beyond traditional enterprise IT environments. Hospitals, water treatment plants, school districts, and now — apparently — court-ordered monitoring equipment.
The ignition interlock industry in the United States is dominated by a handful of companies, including Smart Start, Intoxalock, and LifeSafer, in addition to Draeger. The market exists because of legislation. Every U.S. state has some form of interlock law on the books, and many mandate the devices for first-time offenders. The National Highway Traffic Safety Administration has championed their use. A NHTSA study found that interlocks reduce repeat DUI offenses by approximately 70% while installed. That’s a compelling statistic. But it assumes the devices actually work.
What Draeger’s cyberattack exposed is a single point of failure that courts, legislatures, and regulators have largely ignored. When a judge orders a defendant to install an interlock device, the order doesn’t come with a service-level agreement. There’s no backup plan for server outages. No protocol for cyberattacks. The court assumes the technology will function. The defendant is responsible for ensuring compliance. If the device malfunctions due to a hack on the other side of the Atlantic, the defendant bears the consequences.
This is not a hypothetical concern anymore.
The legal implications are genuinely thorny. Probation officers and courts typically require regular data downloads from interlock devices to verify compliance. If a cyberattack prevents those downloads, does the driver get flagged for noncompliance? If someone misses work because their car won’t start due to a server outage, can they sue the interlock provider? Can they petition the court for relief? These questions don’t have clear answers, and the Draeger incident is likely to force the issue.
Defense attorneys have already begun raising concerns. Some have pointed out that interlock data — which can include GPS information, timestamps, and BAC readings — is transmitted to and stored on company servers. A cyberattack that compromises those servers could theoretically expose sensitive personal data, or worse, corrupt the evidentiary record used to monitor compliance. If a hacker can take down a server, can they also alter the data on it? The integrity of court-mandated monitoring depends on the answer being no. But cybersecurity professionals will tell you that once an attacker is inside a network, the question of what they accessed or modified is often impossible to answer with certainty.
Draeger has not disclosed whether any personal data was compromised in the attack. The company said it activated its incident response protocols and was working with cybersecurity experts to investigate. Standard language. Every breached company says roughly the same thing.
So what should change?
For starters, courts and state legislatures need to grapple with the dependency they’ve created. Mandating a technology without ensuring its resilience is a policy failure waiting to happen — and it just happened. Interlock providers should be required to meet minimum cybersecurity standards as a condition of state certification. Those standards should include redundancy planning: if the central server goes down, the device should have a fallback mode that allows the vehicle to start (after a clean breath sample) while logging data locally for later upload. Some devices already have limited offline functionality. But the specifics vary by manufacturer and model, and there’s no uniform requirement.
States should also establish clear legal protections for drivers affected by provider outages. A driver who can’t start their car because of a cyberattack shouldn’t face a probation violation. That seems obvious. But without explicit guidance, the response will vary from jurisdiction to jurisdiction and judge to judge.
The Draeger incident also raises questions about supply chain risk in criminal justice technology more broadly. Electronic monitoring ankle bracelets, GPS tracking devices for parolees, drug testing systems — all of these rely on networked infrastructure maintained by private companies. A successful cyberattack on any of these providers could disrupt monitoring for thousands of individuals simultaneously, creating both public safety risks (if dangerous offenders slip through the cracks) and civil liberties concerns (if compliant individuals are wrongly flagged).
The cybersecurity industry has spent years warning about attacks on critical infrastructure. The usual examples are power grids, pipelines, and financial systems. Nobody talks about breathalyzers. But when a piece of technology stands between a person and their ability to drive to work — technology mandated by a court of law — it’s critical infrastructure in every sense that matters to the person blowing into it.
Draeger will presumably restore its systems. The drivers who were stranded will eventually get their cars started. The news cycle will move on. But the structural vulnerability remains. Courts across the country continue to order the installation of networked devices in private vehicles, managed by companies whose cybersecurity posture is essentially unaudited by the justice system that depends on them.
That’s not a sustainable arrangement. It’s a ticking clock.
