Hackers Target USB Devices in New Attacks, Researcher warns
USB devices such as keyboards, thumb-drives and mice can be used to hack into personal computers in a potential new class of attacks that evade all known security protections, a top computer researcher revealed yesterday.
Karsten Nohl, chief scientist with Berlin’s SR Labs, noted that hackers could load malicious software onto tiny, low-cost computer chips that control functions of USB devices but which have no built-in shields against tampering with their code.
“You cannot tell where the virus came from. It is almost like a magic trick,” said Nohl, whose research firm is known for uncovering major flaws in mobile phone technology.
The finding shows that bugs in software used to run tiny electronics components that are invisible to the average computer user can be extremely dangerous when hackers figure out how to exploit them. Security researchers have increasingly turned their attention to uncovering such flaws.
Nohl said his firm has performed attacks by writing malicious code onto USB control chips used in thumb drives and smartphones. Once the USB device is attached to a computer, the malicious software can log keystrokes, spy on communications and destroy data, he said.
Computers do not detect the infections when tainted devices are inserted because anti-virus programs are only designed to scan for software written onto memory and do not scan the “firmware” that controls the functioning of those devices, he said.
Nohl and Jakob Lell, a security researcher at SR Labs, will describe their attack method at next week’s Black Hat hacking conference in Las Vegas, in a presentation titled: “Bad USB – On Accessories that Turn Evil.”
Thousands of security professionals gather at the annual conference to hear about the latest hacking techniques, including ones that threaten the security of business computers, consumer electronics and critical infrastructure.
Nohl said he would not be surprised if intelligence agencies, like the National Security Agency, have already figured out how to launch attacks using this technique.
Last year, he presented research at Black Hat on breakthrough methods for remotely attacking SIM cards on mobile phones. In December, documents leaked by former NSA contractor Edward Snowden demonstrated that the U.S. spy agency was using a similar technique for surveillance, which it called “Monkey Calendar.”
SR Labs tested the technique by infecting controller chips made by major Taiwanese manufacturer, Phison Electronics Corp, and placing them in USB memory drives and smartphones running Google Inc’s Android operating system.
Alex Chiu, an attorney with Phison, told Reuters via email that Nohl had contacted the company about his research in May.
“Mr. Nohl did not offer detailed analysis together with work product to prove his finding,” Chiu said. “Phison does not have ground to comment (on) his allegation.”
Chiu said that “from Phison’s reasonable knowledge and belief, it is hardly possible to rewrite Phison’s controller firmware without accessing our confidential information.”
Similar chips are made by Silicon Motion Technology Corp and Alcor Micro Corp. Nohl said his firm did not test devices with chips from those manufacturers.
Google did not respond to requests for comment. Officials with Silicon Motion and Alcor Micro could not immediately be reached.
Nohl believed hackers would have a “high chance” of corrupting other kinds of controller chips besides those made by Phison, because their manufacturers are not required to secure software. He said those chips, once infected, could be used to infect mice, keyboards and other devices that connect via USB.
“The sky is the limit. You can do anything at all,” he said.
In his tests, Nohl said he was able to gain remote access to a computer by having the USB instruct the computer to download a malicious program with instructions that the PC believed were coming from a keyboard. He was also able to change what are known as DNS network settings on a computer, essentially instructing the machine to route Internet traffic through malicious servers.
Once a computer is infected, it could be programmed to infect all USB devices that are subsequently attached to it, which would then corrupt machines that they contact.
“Now all of your USB devices are infected. It becomes self-propagating and extremely persistent,” Nohl said. “You can never remove it.”
Christof Paar, a professor of electrical engineering at Germany’s University of Bochum who reviewed the findings, said he believed the new research would prompt others to take a closer look at USB technology, and potentially lead to the discovery of more bugs. He urged manufacturers to improve protection of their chips to thwart attacks.
“The manufacturer should make it much harder to change the software that runs on a USB stick,” Paar said.
Nigeria has taken a major step toward strengthening its digital governance framework as the National Information Technology Development Agency (NITDA) officially assumes control of the Nigeria Government Enterprise Architecture (NGEA) infrastructure.
The handover ceremony held in Abuja, marks the culmination of a high-level partnership with the Korea International Cooperation Agency (KOICA).
This transition signals a shift from fragmented IT projects to a unified, disciplined approach to national digital investment.
The NGEA initiative forms a core part of the e-Government Masterplan 2.0 (Ne-GMP 2.0), aimed at establishing a unified and structured approach to managing government IT investments and digital resources.
The framework is designed to ensure that technology deployment across public institutions aligns with national priorities while improving efficiency and accountability.
With the system now operational, government agencies are expected to adopt more integrated digital processes, allowing seamless data sharing and interoperability.
This is anticipated to reduce duplication, strengthen risk management, and translate policy objectives into measurable digital outcomes.
Over the past two and a half years, Nigerian technical experts worked closely with their Korean counterparts to develop the architecture framework, create reference models, and execute pilot programmes in key institutions.
These include the National Identity Management Commission, Nigeria Customs Service, Nigeria Immigration Service, and NITDA.
Officials say the NGEA represents a shift from fragmented digital efforts to a more coordinated, citizen-focused system.
The infrastructure is hosted by Galaxy Backbone Limited, providing a secure and reliable platform for nationwide deployment.
Looking ahead, NITDA is expected to work with government stakeholders to expand and sustain the system, while the Federal Ministry of Communications, Innovation and Digital Economy will provide policy guidance to ensure its adoption across the country.
Bosun Tijani, minister of Communications, Innovation and Digital Economy, has said the government is shifting focus from expanding access to ensuring “meaningful connectivity” that drives economic growth and inclusion.

The minister made the statement on Friday while addressing stakeholders at the inauguration of board members of the Universal Service Provision Fund (USPF) in Abuja.
He said that although Nigeria had made significant progress since the introduction of GSM services, millions of people, particularly in rural and underserved communities, remain either unconnected or unable to fully benefit from digital services.
Dr Tijani highlighted ongoing investments in digital infrastructure, including plans to deploy 90,000 kilometres of fibre optic network and nearly 4,000 telecom towers nationwide.
He said initiatives under the USPF had improved access through projects such as rural connectivity and digital facilities in schools but stressed that the next phase must prioritise effective usage.
“It is not enough to connect a community. We must ensure that schools can teach with digital tools and that small businesses can access market opportunities,” he said, citing a pilot project in the Kura community where connectivity has enhanced access to communication, education and healthcare.
Aminu Maida, executive vice chairman, Nigerian Communications Commission (NCC) also called for a shift towards meaningful connectivity, noting that while data usage had grown significantly, it remained concentrated in urban areas.
According to him, recent data shows that telecom usage has increased by about 160% over the past two years, largely driven by urban demand.
“When we drill down, we see that a lot of that growth is actually in urban centres. So, the gap between those who are not connected or not meaningfully connected is growing,” he said.
Dr Maida added that the trend underscored the need for the USPF board to intensify efforts to bridge both access and usage gaps across the country.
Both officials emphasised the importance of collaboration, sustainable investment models and improved digital literacy to ensure that connectivity translates into real economic benefits for Nigerians.
A jury in Los Angeles has found technology companies, Meta and Google liable for contributing to a young woman’s social media addiction, in a case being described as a landmark ruling.
The 20-year-old woman, identified only as Kaley, argued that she became addicted to Google’s YouTube and Meta’s Instagram from an early age due to their attention-driven design features.
According to her testimony, she began using YouTube at the age of six after downloading the app on her iPod Touch to watch videos about lip gloss and online games.
Kaley told the court that she joined Instagram at nine, bypassing parental restrictions put in place by her mother, and spent extended periods on social media.
The trial, which lasted about a month, with arguments and evidence from both sides.
Jurors also heard testimony from Mark Zuckerberg, chief executive, Meta and Adam Mosseri, Instagram head.
However, Neal Mohan, YouTube chief executive, did not testify.
The jury found that the companies were negligent in the design of their platforms and failed to adequately warn users about potential harms. Meta and Google were ordered to pay the woman $3 million in damages.
Jurors also recommended additional punitive damages, including $900,000 against YouTube and $2.1 million against Meta, according to company spokespersons.
The jury apportioned 70 per cent of the responsibility to Meta and 30 per cent to YouTube.
Kaley was present in the courtroom when the verdict was delivered, alongside parents of other teenagers who say they were harmed by social media use. Both companies said they plan to appeal the decision.
“We respectfully disagree with the verdict and will appeal. Teen mental health is profoundly complex and cannot be linked to a single app. We will continue to defend ourselves vigorously as every case is different, and we remain confident in our record of protecting teens online”, a Meta spokesperson said.
José Castañeda, Google spokesperson, said the case misunderstands YouTube, which is a responsibly built streaming platform, not a social media site.
