Android botnet Kimwolf infects nearly two million smart devices

Cybersecurity researchers have identified a large Android-based botnet capable of more than distributed denial-of-service attacks, highlighting growing risks from compromised consumer devices. The botnet, dubbed Kimwolf, is estimated to control close to two million infected systems worldwide.

The findings come from QiAnXin XLab, which said Kimwolf has infected around 1.8 million devices, mainly smart TVs, set-top boxes and tablets. Most infections were observed in Brazil, India, the US, Argentina, South Africa and the Philippines.

XLab said the infection vector remains unclear, but affected devices were linked to low-cost Android-based brands used for media streaming. Researchers noted repeated attempts to disrupt the Kimwolf, with its command-and-control infrastructure taken down several times before re-emerging.

According to the report, Kimwolf has adapted by shifting to decentralised infrastructure, including the use of Ethereum Name Service domains. Analysts also identified overlaps in code and infrastructure with AISURU, a botnet linked to record-scale DDoS attacks.

Cloudflare recently described AISURU as one of the largest robot networks observed, capable of attacks exceeding 29 terabits per second. XLab said shared infrastructure suggests both botnets are operated by the same threat group.

EU moves to extend child abuse detection rules

The European Commission has proposed extending the Interim Regulation that allows online service providers to voluntarily detect and report child sexual abuse instead of facing a legal gap once the current rules expire.

These measures would preserve existing safeguards while negotiations on permanent legislation continue.

The Interim Regulation enables providers of certain communication services to identify and remove child sexual abuse material under a temporary exemption from e-Privacy rules.

Without an extension beyond April 2026, voluntary detection would have to stop, making it easier for offenders to share illegal material and groom children online.

According to the Commission, proactive reporting by platforms has played a critical role for more than fifteen years in identifying abuse and supporting criminal investigations. Extending the interim framework until April 2028 is intended to maintain these protections until long-term EU rules are agreed.

The proposal now moves to the European Parliament and the Council, with the Commission urging swift agreement to ensure continued protection for children across the Union.

UK plans ban on deepfake AI nudification apps

Britain plans to ban AI-nudification apps that digitally remove clothing from images. Creating or supplying these tools would become illegal under new proposals.

The offence would build on existing UK laws covering non-consensual sexual deepfakes and intimate image abuse. Technology Secretary Liz Kendall said developers and distributors would face harsh penalties.

Experts warn that nudification apps cause serious harm, mainly when used to create child sexual abuse material. Children’s Commissioner Dame Rachel de Souza has called for a total ban on the technology.

Child protection charities welcomed the move but want more decisive action from tech firms. The government said it would work with companies to stop children from creating or sharing nude images.

AI-generated video falsely claims US military to ‘take over’ Nigerian army

A video circulating online, purported to show a US military officer announcing that the United States would take control of the Nigerian Army, is false.

Independent analysis has revealed that the clip was likely generated or heavily manipulated using AI, and no official announcement or credible source supports this claim.

Fact-checkers used AI-detection tools and found high levels of manipulation, and investigations uncovered inconsistencies in uniform insignia and microphones linked to non-existent media outlets. No verified reports indicate that US military forces are intervening in Nigerian defence operations.

The false claim has spread on platforms including X (formerly Twitter), generating alarm and misinterpretation about foreign military involvement in Nigeria.

Experts warn that deepfakes and AI-generated misinformation are becoming harder to spot without specialised tools and verification.

UK Foreign Office hit by cyber-attack

The UK Foreign, Commonwealth and Development Office was hacked in October, according to minister Chris Bryant. Officials say there is a low risk to any individual from the breach.

Reports suggest that a Chinese group, Storm 1849, may have been involved, but Bryant cautioned that the perpetrator has not been confirmed. Tens of thousands of visa details could have been targeted, though the exact scope remains unclear.

The attack shares similarities with a 2024 campaign called ArcaneDoor, linked to state-sponsored actors. Cybersecurity experts warn that the incidents may be connected and highlight risks of large-scale data targeting.

Officials have quickly closed the vulnerability and continue to investigate the matter. Bryant emphasised that speculation is unhelpful and said the investigation could take some time to identify the responsible party.

Digital fraud declines in Russia after rollout of Cyberbez measures

Russia has reported a sharp decline in cyber fraud following the introduction of new regulatory measures in 2025. Officials say legislative action targeting telephone and online scams has begun to deliver measurable results.

State Secretary and Deputy Minister of Digital Development Ivan Lebedev told the State Duma that crimes covered by the first package of reforms, known as ‘Cyberbez 1.0’, have fallen by 40%, according to confirmed statistics.

Earlier this year, Lebedev said Russia records roughly 677,000 cases of phone and online fraud annually, with incidents rising by more than 35% since 2022, highlighting the scale of the challenge faced by authorities.

In April, President Vladimir Putin signed a law introducing a range of countermeasures, including a state information system to combat fraud, limits on unsolicited marketing calls, stricter SIM card issuance rules, and new compliance obligations for banks.

Further steps are now under discussion. Officials say a second package is being prepared, while a third set of initiatives was announced in December as Russia continues to strengthen its digital security framework.

New Kimwolf Android botnet linked to a record-breaking DDoS attacks

Cybersecurity researchers have uncovered a rapidly expanding Android botnet known as Kimwolf, which has already compromised approximately 1.8 million devices worldwide.

The malware primarily targets smart TVs, set-top boxes, and tablets connected to residential networks, with infections concentrated in countries including Brazil, India, the US, Argentina, South Africa, and the Philippines.

Analysis by QiAnXin XLab indicates that Kimwolf demonstrates a high degree of operational resilience.

Despite multiple disruptions to its command-and-control infrastructure, the botnet has repeatedly re-emerged with enhanced capabilities, including the adoption of Ethereum Name Service to harden its communications against takedown efforts.

Researchers also identified significant similarities between Kimwolf and AISURU, one of the most powerful botnets observed in recent years. Shared source code, infrastructure, and infection scripts suggest both botnets are operated by the same threat group and have coexisted on large numbers of infected devices.

AISURU has previously drawn attention for launching record-setting distributed denial-of-service attacks, including traffic peaks approaching 30 terabits per second.

The emergence of Kimwolf alongside such activity highlights the growing scale and sophistication of botnet-driven cyber threats targeting global internet infrastructure.

Crypto theft soars in 2025 with fewer but bigger attacks

Cryptocurrency theft intensified in 2025, with total stolen funds exceeding $3.4 billion despite fewer large-scale incidents. Losses became increasingly concentrated, with a few major breaches driving most of the annual damage and widening the gap between typical hacks and extreme outliers.

North Korea remained the dominant threat actor, stealing at least $2.02 billion in digital assets during the year, a 51% increase compared with 2024.

Larger thefts were achieved through fewer operations, often relying on insider access, executive impersonation, and long-term infiltration of crypto firms rather than frequent attacks.

Laundering activity linked to North Korean actors followed a distinctive and disciplined pattern. Stolen funds moved in smaller tranches through Chinese-language laundering networks, bridges, and mixing services, usually following a structured 45-day cycle.

Individual wallet attacks surged, impacting tens of thousands of victims, while the total value stolen from personal wallets fell. Decentralised finance remained resilient, with hack losses low despite rising locked capital, indicating stronger security practices.

Customer trust at risk as retail cyberattacks grow

Retailers face escalating cyber threats as hackers increasingly target customer data, eroding trust and damaging long-term brand value.

Deloitte warns that data breaches and ransomware attacks are becoming more frequent and costly, with some retailers facing losses reaching hundreds of millions, alongside declining consumer confidence.

The expansion of AI-driven personalisation has intensified privacy concerns, as customers weigh convenience against data protection.

While many shoppers accept sharing personal information in exchange for value, confidence depends on clear safeguards, transparent data use and credible security practices across digital channels.

Deloitte argues that leading retailers integrate cybersecurity into their core business strategy, rather than treating it as a compliance obligation.

Priorities include protecting critical digital assets, modernising security operations and building cyber-aware cultures capable of responding to AI-enabled fraud, preserving customer trust and sustaining revenue growth.
