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.

NIMC Says NIN Services Back Online

National Identity Management Commission (NIMC) has announced the restoration of its National Identification Number (NIN) verification services nationwide.
This, according to the commission, follows the completion of a system maintenance exercise.
In a statement issued on Friday, the NIMC confirmed that all previously disrupted services have resumed.
“NIMC wishes to inform the general public that the recent technical maintenance has been completed and all services have been restored,” the statement read.
The NIMC urged Nigerians seeking to enroll for NIN to visit the its official website to locate the nearest enrollment centers.
The agency also encouraged individuals to make use of its self-service portal for tasks such as data modification, including name changes.
To further ease the verification process, the Commission recommended downloading the NIMC NameAuth app (oath.app) from the Google Play Store or Apple App Store for quick and secure NIN authentication.
NIMC expressed appreciation for the public’s patience during the service disruption, which had impacted banks, telecom providers, and government agencies that rely on NIN verification for their operations.

Report Reveals African Organizations Dangerously Overestimating Cyber defences

Many businesses are overestimating their defence against cyber attacks, which creates a significant human risk blind spot. A new KnowBe4 report exposes a worrying disconnect between what leaders think about their cyber security readiness and what employees experience.
According to the KnowBe4 Africa Human Risk Management Report 2025, based on insights from cyber security decision-makers across 30 African countries, despite high awareness, a critical gap exists in turning that awareness into actual readiness and resilient behaviour.
Key findings from the KnowBe4 Africa Human Risk Management Report 2025:
Confidence vs awareness: While cyber security awareness is high, leaders express uncertainty about their workforce’s ability to act on that awareness. Many feel employees may overestimate their capabilities in recognising, reporting and mitigating threats.
The need for adaptive and personalised security awareness training: Many companies fail to personalise security awareness training to specific roles or risk exposures.
Widespread BYOD usage: A large percentage of employees (between 41% and 80%) use their personal devices for work.
AI policy development is lagging: Many companies (46%) are still in the process of developing policies for using AI tools in the workplace.
Regional variation: Southern Africa trains more, East Africa governs AI better and West/Central Africa sees the most human-related security incidents.
This gap is significant because Africa has become an attractive target to cyber criminals, especially those that launch AI-powered attacks. A LexisNexis Risk Solutions study found 60% of South African organisations have seen an increase in AI-facilitated financial crime – above the 56% global average.
Kehinde Popoola, regional manager and key representative for West and East Africa at Rubrik, said digital transformation is gaining momentum in Africa and companies are more exposed to cyber risk. The Rubrik executive adds that amid an increase in threats, it is crucial that organisations adopt an assumed breach mindset.
The KnowBe4 research shows that cyber security preparedness and the actual structures required to support secure behaviour seem misaligned.
The report highlights that just 10% of cyber security leaders are fully confident that staff would report a phishing attack or other cyber threat, despite rating employee security awareness of cyber threats at four out of five or higher.
There is also a significant perception gap between decision-makers and general employees in Africa regarding security awareness training, with 68% of leaders believing that training is tailored to roles, compared to only a third of employees feeling adequately trained.
KnowBe4 asserts that many organisations only conduct annual or biannual training that is too generic to effectively change behaviour, contributing to uncertainty about its effectiveness.
According to another report, the KnowBe4 African Cybersecurity and Awareness Report 2025, which focuses on end-user based responses, only 43% of African respondents felt confident in their ability to recognise a cyber threat, and just one in three believed their security awareness training was adequately tailored to their role. This comparison suggests the development of a dangerous perception gap in many organisations.
“There’s a disconnect here – between what leaders think is happening and what employees are actually experiencing,” says Anna Collard, SVP content strategy and evangelist at KnowBe4 Africa. “The data shows that without procedural and cultural follow-through, awareness simply doesn’t translate into readiness.”
“The continent’s cyber security posture may be more confident than it is truly resilient,” Collard adds.

Domain of Deception as Attackers Deploy Spyware Under Guise of Legal Threats

Kaspersky has detected a rapidly escalating malicious campaign that has targeted over 1,100 corporate users since June 2025. The attackers pose as a legal firm and in their emails threaten recipients with lawsuits over alleged domain name patent violations, aiming to deploy malware.
Victims who opened and launched the attached files – that mimicked legal documents – had a Trojan installed on their devices, and the attackers could spy on the content of their screens. Organisations across healthcare, finance, and education sectors have been targeted.
The campaign began with 95 emails on June 11 and has since continued to escalate. Apart from claiming that the recipient’s domain name violates patented combinations of a major brand and threatening litigation, in the email the fake legal bureau also expresses the patent holders’ interest in acquiring the domain and offers getting acquainted with the details of the alleged violations by opening the attached archive with “documents”.
It is worth noting that the attackers, likely to avoid detection, attach an archive that is not password protected, and inside it includes another archive that is password protected and a file containing the password along with it.
After the user entered the archive password and clicked on the alleged legal document inside, a Trojan was installed on the device. The user saw a message displayed that read, “This document cannot be opened on this device. Try opening it on another windows device,” and simultaneously the Tor Browser was covertly downloaded and installed in the background.
Through it, the malware regularly sent snapshots of the user’s screen to the attackers over the Tor network. The malware also autostarts whenever the computer is restarted.
“This campaign is a sophisticated blend of psychological manipulation and technical deception, leveraging fear of legal action to coerce businesses into executing harmful files hidden in attached archives. Its rapid growth since June 11 underscores the urgency for organisations to bolster defenses.
Victims face the risk of losing their private data. Robust email security, employee training, and swift incident reporting are essential to counter this evolving threat,” comments Anna Lazaricheva, spam analyst at Kaspersky.
