(Press-News.org) Portable genetic sequencers used around the world to sequence DNA have critical, previously unreported security vulnerabilities that could reveal or alter genetic information without detection, according to a new study.
Researchers from the University of Florida have, for the first time, exposed these security risks in devices from Oxford Nanopore Technologies, which produces nearly all the portable genetic sequencers in the world.
Alerted by the security researchers, Oxford Nanopore Technologies has rolled out updated software to patch the vulnerabilities. But out-of-date software, or unsecured internet systems, could still leave some DNA sequencers vulnerable to attack.
“No one in the world had looked at the security of these devices, which shocked me,” said Christina Boucher, Ph.D., a professor of computer and information science and engineering at UF, expert in bioinformatics, and co-author of the new report.
Boucher collaborated with Sara Rampazzi, Ph.D., also a professor of computer and information science and engineering, cybersecurity expert and project lead at UF, and students in the department to test Nanopore sequencers for security flaws. The study serves as a warning to the scientific community that new threats to genomic data urge a shift toward “secure-by-design” systems as portable DNA sequencers become increasingly common The team published their findings Nov.10 in Nature Communications.
The researchers uncovered three vulnerabilities in the Oxford Nanopore MinION portable sequencer and its associated software. Two of these flaws allow an unauthorized user to improperly access the device and potentially copy or alter the DNA data without the authorized user’s knowledge. A third flaw opens the sequencer to a denial-of-service attack, which would halt the sequencing operation and make the device appear broken.
The Cybersecurity and Infrastructure Security Agency, the federal government’s cyber defense coordinator, verified these vulnerabilities in a report released Oct. 21. The report also provides instructions from Oxford Nanopore Technologies on how users can update their sequencers to address the security flaws.
Versions with older software would remain open to attack. This is especially possible when the portable sequencers are connected to insecure Wi-Fi networks or remote control is activated.
Costing just a few thousand dollars and able to operate anywhere in the world, these palm-sized sequencers have transformed the previously cumbersome and expensive work of sequencing DNA. But that portability contributes to the security risks of these devices because the sequencers must be connected to a computer to work.
“You are connecting a very specialized device to a general-purpose device like a laptop, which is intrinsically assumed to be secure,” said Rampazzi. “Instead, that laptop could be connected to an unsecured network, or it could be infected with malware or ransomware, especially if used in the field outside controlled environments.”
These nanopore sequencers are marketed only for research use and not to be used for clinical diagnosis. Yet even when restricted to research, these devices can be used to sequence the DNA of people.
The U.S. National Institute of Standards and Technology, which focuses on defining genomic cybersecurity and privacy guidelines, has only started to consider research use cases in distinction to clinical use in their latest draft guidelines, highlighting the increased attention on the topic and the lack of a clear standard.
Revealing these previously undiscovered vulnerabilities was only possible due to the interdisciplinary collaboration between the Rampazzi and Boucher labs. Boucher develops algorithms to better analyze DNA, while Rampazzi researches security flaws in critical systems ranging from medical devices, and self-driving cars to underwater data centers. Combining their expertise helped alert the community to a significant privacy threat.
“In bioinformatics, we haven’t been working as closely with the security community as I think we should be,” Boucher said.

‘Roadmap’ shows the environmental impact of AI data center boom
2025-11-10
ITHACA, N.Y. - As the everyday use of AI has exploded in recent years, so have the energy demands of the computing infrastructure that supports it. But the environmental toll of these large data centers, which suck up gigawatts of power and require vast amounts of water for cooling, has been too diffuse and difficult to quantify.
Now, Cornell researchers have used advanced data analytics – and, naturally, some AI, too – to create a state-by-state look at that environmental impact. The team found that, by 2030, the current rate of AI growth would annually put 24 to 44 million metric tons of carbon dioxide into the ...
Scientists discover chameleon’s telephone-cord-like optic nerves once overlooked by Aristotle and Newton
2025-11-10
Chameleons’ wandering eyes have fascinated and puzzled scientists since the days of ancient Greece. Now, after millennia of study, modern imaging has revealed the secret of their nearly 360-degree view and uncanny ability to look in two different directions at once. Behind their bulging eyes lie two long, coiled optic nerves — a structure not seen in any other lizard.
“Chameleon eyes are like security cameras, moving in all directions,” explained Juan Daza, associate professor at Sam Houston State University and author of a new study describing the trait. “They ...
One enzyme could be behind alcohol addiction and liver disease
2025-11-10
AURORA, Colo. (November 10, 2025) – Scientists have uncovered a surprising connection between sugar metabolism and alcohol addiction, identifying a potential new therapeutic target for treating alcohol-associated liver disease (ALD) and alcohol use disorder (AUD).
In a new study, out today in Nature Metabolism, University of Colorado Anschutz researchers found that alcohol triggers a metabolic pathway in the body that leads to the internal production of fructose, the same type of sugar commonly ...
Neanderthal DNA helps explain how faces form
2025-11-10
Every human face is unique, allowing us to distinguish between individuals. We know little about how facial features are encoded in our DNA, but we may be able to learn more about how our faces develop by looking at our ancient relatives, the Neanderthals. Neanderthal faces were quite distinctive from our own, with large noses, pronounced brows and a robust lower jaw. Now, scientists from the MRC Human Genetics Unit in the Institute of Genetics and Cancer at the University of Edinburgh, UK, are using the DNA of our extinct ...

How plastics grip metals at the atomic scale
2025-11-10
What makes some plastics stick to metal without any glue? Osaka Metropolitan University scientists peered into the invisible adhesive zone that forms between certain plastics and metals — one atom at a time — to uncover how chemistry and molecular structure determine whether such bonds bend or break.
Their insights clarify metal–plastic bonding mechanisms and offer guidelines for designing durable, lightweight, and more sustainable hybrid materials for use in transportation.
Combining the strength of metal with the lightness and flexibility of plastic, polymer–metal hybrid structures are emerging as key elements for building lighter, more fuel-efficient vehicles. ...
Human impact on Amazon forests is transforming its ecological functions and evolutionary history
2025-11-10
A new study reveals that the impact humans are having on the Amazon rainforest is so profound it is even changing the evolutionary history and functionality of the forests.
As the world gathers at COP30 to discuss climate in the world’s largest rainforest, the focus is often on the carbon that these forests either store or sequester.
However, tropical forests are much more than just carbon: they are among the biggest reservoirs of biodiversity on the planet. For example, the Amazon holds up to 16,000 species of tree alone, with a single hectare frequently holding more than 300 species. In comparison, the UK has just 32 species of ...
Could a liquid biopsy test lead to earlier diagnoses for numerous cancer types?
2025-11-10
Routine screening is limited to only a few cancer types. New research indicates that routine liquid biopsy testing (multi-cancer early detection testing) could substantially reduce late-stage cancer diagnoses, allowing patients to receive treatment at earlier cancer stages, which are more likely to respond to interventions. The findings are published by Wiley online in CANCER, a peer-reviewed journal of the American Cancer Society.
Currently, routine screening is only recommended for four types of cancer, leaving approximately 70% of new cancer cases to be detected only after symptoms appear, often at an advanced stage when survival ...
Link found between chronic fatigue and abnormal breathing could lead to new treatments
2025-11-10
Chronic fatigue syndrome leaves patients exhausted and struggling with brain fog — and it typically gets worse after mental or physical exercise, a phenomenon called post-exertional malaise. Now scientists investigating shortness of breath in chronic fatigue patients have discovered that they are highly likely to experience dysfunctional breathing, which could be caused by dysautonomia, abnormal control of innervation to blood vessels and muscles. Targeting treatments towards these breathing problems ...
