TikTok launches new tools to manage AI-generated content

TikTok has announced new tools to help users shape and understand AI-generated content (AIGC) in their feeds. A new ‘Manage Topics’ control will let users adjust how much AI content appears in their For You feeds alongside keyword filters and the ‘not interested’ option.

The aim is to personalise content rather than remove it entirely.

To strengthen transparency, TikTok is testing ‘invisible watermarking’ for AI-generated content created with TikTok tools or uploaded using C2PA Content Credentials. Combined with creator labels and AI detection, these watermarks help track and identify content even if edited or re-uploaded.

The platform has launched a $2 million AI literacy fund to support global experts in creating educational content on responsible AI. TikTok collaborates with industry partners and non-profits like Partnership on AI to promote transparency, research, and best practices.

Investments in AI extend beyond moderation and labeling. TikTok is developing innovative features such as Smart Split and AI Outline to enhance creativity and discovery, while using AI to protect user safety and improve the well-being of its trust and safety teams.

Poll manipulation by AI threatens democratic accuracy, according to a new study

Public opinion surveys face a growing threat as AI becomes capable of producing highly convincing fake responses. New research from Dartmouth shows that AI-generated answers can pass every quality check, imitate real human behaviour and alter poll predictions without leaving evidence.

In several major polls conducted before the 2024 US election, inserting only a few dozen synthetic responses would have reversed expected outcomes.

The study reveals how easily malicious actors could influence democratic processes. AI models can operate in multiple languages yet deliver flawless English answers, allowing foreign groups to bypass detection.

An autonomous synthetic respondent that was created for the study passed nearly all attention tests, avoided errors in logic puzzles and adjusted its tone to match assigned demographic profiles instead of exposing its artificial nature.

The potential consequences extend far beyond electoral polling. Many scientific disciplines rely heavily on survey data to track public health risks, measure consumer behaviour or study mental wellbeing.

If AI-generated answers infiltrate such datasets, the reliability of thousands of studies could be compromised, weakening evidence used to shape policy and guide academic research.

Financial incentives further raise the risk. Human participants earn modest fees, while AI can produce survey responses at almost no cost. Existing detection methods failed to identify the synthetic respondent at any stage.

The researcher urges survey companies to adopt new verification systems that confirm the human identity of participants, arguing that stronger safeguards are essential to protect democratic accountability and the wider research ecosystem.

Cloudflare outage disrupts leading crypto platforms

Cloudflare experienced a significant network outage on Tuesday, which disrupted access to major cryptocurrency platforms, including Coinbase, Kraken, Etherscan, and several DeFi services, resulting in widespread ‘500 Internal Server Error’ messages.

The company acknowledged the issue as an internal service degradation across parts of its global network and began rolling out a fix. However, users continued to face elevated error rates during the process.

Major Bitcoin and Ethereum platforms, as well as Aave, DeFiLlama, and several blockchain explorers, were impacted. The disruption spread beyond crypto, affecting several major Web2 platforms, while services like BlueSky and Reddit stayed fully operational.

Cloudflare shares dropped 3.5% in pre-market trading as the company investigated whether scheduled maintenance at specific data centres played any role.

The incident marks the third significant Cloudflare disruption affecting crypto platforms since 2019, highlighting the industry’s ongoing reliance on centralised infrastructure providers despite its focus on decentralisation.

Industry experts pointed to recent outages from Cloudflare and Amazon Web Services as evidence that critical digital services cannot rely solely on a single vendor for reliability. Kraken restored access ahead of many peers, while Cloudflare stated that the issue was resolved and would continue to monitor for full stability.

Singapore’s HTX boosts Home Team AI capabilities with Mistral partnership

HTX has signed a new memorandum of understanding with France’s Mistral AI to accelerate joint research on large language and multimodal models for public safety. The partnership will expand into embodied AI, video analytics, cybersecurity, and automated fire safety systems.

The deal builds on earlier work co-developing Phoenix, HTX’s internal LLM series, and a Home Team safety benchmark for evaluating model behaviour. The organisations will now collaborate on specialised models for robots, surveillance platforms, and cyber defence tools.

Planned capabilities include natural-language control of robotic systems, autonomous navigation in unfamiliar environments, and object retrieval. Video AI tools will support predictive tracking and proactive crime alerts across multiple feeds.

Cybersecurity applications include automated architecture reviews and on-demand vulnerability testing. Fire safety tools will use multimodal comprehension to analyse architectural plans and flag compliance issues without manual checks.

The partnership forms part of the HTxAI movement, which aims to strengthen Home Team AI capacity through research collaborations with industry and academia. Mistral’s flagship models, Mistral Medium 3.1 and Magistral, are currently among the top performers in multilingual and multimodal benchmarks.

Outage at Cloudflare takes multiple websites offline worldwide

Cloudflare has suffered a major outage, disrupting access to multiple high-profile websites, including X and Letterboxd. Users encountered internal server error messages linked to Cloudflare’s network, prompting concerns of a broader infrastructure failure.

The problems began around 11.30 a.m. UK time, with some sites briefly loading after refreshes. Cloudflare issued an update minutes later, confirming that it was aware of an incident affecting multiple customers but did not identify a cause or timeline for resolution.

Outage tracker Down Detector was also intermittently unavailable, later showing a sharp rise in reports once restored. Affected sites displayed repeated error messages advising users to try again later, indicating partial service degradation rather than full shutdowns.

Cloudflare provides core internet infrastructure, including traffic routing and cyberattack protection, which means failures can cascade across unrelated services. Similar disruption followed an AWS incident last month, highlighting the systemic risk of centralised web infrastructure.

The company states that it is continuing to investigate the issue. No mitigation steps or source of failure have yet been disclosed, and Cloudflare has warned that further updates will follow once more information becomes available.

Eurofiber France confirms the major data breach

The French telecommunications company Eurofiber has acknowledged a breach of its ATE customer platform and digital ticket system after a hacker accessed the network through software used by the company.

Engineers detected the intrusion quickly and implemented containment measures, while the company stressed that services remained operational and banking data stayed secure. The incident affected only French operations and subsidiaries such as Netiwan, Eurafibre, Avelia, and FullSave, according to the firm.

Security researchers instead argue that the scale is far broader. International Cyber Digest reported that more than 3,600 organisations may be affected, including prominent French institutions such as Orange, Thales, the national rail operator, and major energy companies.

The outlet linked the intrusion to the ransomware group ByteToBreach, which allegedly stole Eurofiber’s entire GLPI database and accessed API keys, internal messages, passwords and client records.

A known dark web actor has now listed the stolen dataset for sale, reinforcing concerns about the growing trade in exposed corporate information. The contents reportedly range from files and personal data to cloud configurations and privileged credentials.

Eurofiber did not clarify which elements belonged to its systems and which originated from external sources.

The company has notified the French privacy regulator CNIL and continues to investigate while assuring Dutch customers that their data remains safe.

A breach that underlines the vulnerability of essential infrastructure providers across Europe, echoing recent incidents in Sweden, where a compromised IT supplier exposed data belonging to over a million people.

Eurofiber says it aims to strengthen its defences instead of allowing similar compromises in future.

Report calls for new regulations as AI deepfakes threaten legal evidence

US courtrooms increasingly depend on video evidence, yet researchers warn that the legal system is unprepared for an era in which AI can fabricate convincing scenes.

A new report led by the University of Colorado Boulder argues that national standards are urgently needed to guide how courts assess footage generated or enhanced by emerging technologies.

The authors note that judges and jurors receive little training on evaluating altered clips, despite more than 80 percent of cases involving some form of video.

Concerns have grown as deepfakes become easier to produce. A civil case in California collapsed in September after a judge ruled that a witness video was fabricated, and researchers believe such incidents will rise as tools like Sora 2 allow users to create persuasive simulations in moments.

Experts also warn about the spread of the so-called deepfake defence, where lawyers attempt to cast doubt on genuine recordings instead of accepting what is shown.

AI is also increasingly used to clean up real footage and to match surveillance clips with suspects. Such techniques can improve clarity, yet they also risk deepening inequalities when only some parties can afford to use them.

High-profile errors linked to facial recognition have already led to wrongful arrests, reinforcing the need for more explicit courtroom rules.

The report calls for specialised judicial training, new systems for storing and retrieving video evidence and stronger safeguards that help viewers identify manipulated content without compromising whistleblowers.

Researchers hope the findings prompt legal reforms that place scientific rigour at the centre of how courts treat digital evidence as it shifts further into an AI-driven era.

Deepfakes surge as scammers exploit AI video tools

Experts warn online video is entering a perilous new phase as AI deepfakes spread. Analysts say totals climbed from roughly 500,000 in 2023 to eight million in 2025.

Security researchers say deepfake scams have risen by more than 3,000 percent recently. Studies also indicate humans correctly spot high-quality fakes only around one in four times. People are urged to question surprising clips, verify stories elsewhere and trust their instincts.

Video apps such as Sora 2 create lifelike clips that fraudsters reuse for scams. Sora passed one million downloads and later tightened rules after racist deepfakes of Martin Luther King Jr.

Specialists at Outplayed suggest checking eye blinks, mouth movements and hands for subtle distortions. Inconsistent lighting, unnaturally smooth skin or glitching backgrounds can reveal manipulated or AI-generated video.

US states weigh VPN restrictions to protect minors online

US legislators in Wisconsin and Michigan are weighing proposals that would restrict the use of VPNs to access sites deemed harmful to minors. The bills build on age-verification rules for websites hosting sexual content, which lawmakers say are too easy to bypass when users connect via VPNs.

In Wisconsin, a bill that has already passed the State Assembly would require adult sites to both verify age and block visitors using VPNs, potentially making the state the first in the US to outlaw VPN use for accessing such content if the Senate approves it.

In Michigan, similar legislation would go further by obliging internet providers to monitor and block VPN connections, though that proposal has yet to advance.

The Digital Rights Group and the Electronic Frontier Foundation argue that the approach would erode privacy for everyone, not just minors.

It warns that blanket restrictions would affect businesses, students, journalists and abuse survivors who rely on VPNs for security, calling the measures ‘surveillance dressed up as safety’ and urging lawmakers instead to improve education, parental tools and support for safer online environments.

The debate comes as several European countries, including France, Italy and the UK, have introduced age-verification rules for pornography sites, but none have proposed banning VPNs.

New report warns retailers are unprepared for AI-powered attacks

Retailers are entering the peak shopping season amid warnings that AI-driven cyber threats will accelerate. LevelBlue’s latest Spotlight Report says nearly half of retail executives are already seeing significantly higher attack volumes, while one-third have suffered a breach in the past year.

The sector is under pressure to roll out AI-driven personalisation and new digital channels, yet only a quarter feel ready to defend against AI attacks. Readiness gaps also cover deepfakes and synthetic identity fraud, even though most expect these threats to arrive soon.

Supply chain visibility remains weak, with almost half of executives reporting limited insight into software suppliers. Few list supplier security as a near-term priority, fuelling concern that vulnerabilities could cascade across retail ecosystems.

High-profile breaches have pushed cybersecurity into the boardroom, and most retailers now integrate security teams with business operations. Leadership performance metrics and risk appetite frameworks are increasingly aligned with cyber resilience goals.

Planned investment is focused on application security, business-wide resilience processes, and AI-enabled defensive tools. LevelBlue argues that sustained spending and cultural change are required if retailers hope to secure consumer trust amid rapidly evolving threats.
