AT&T hit by alleged 31 million record breach

A hacker has allegedly leaked data from 31 million AT&T customers, raising fresh concerns over the security of one of America’s largest telecom providers. The data, posted on a major dark web forum in late May 2025, is said to contain 3.1GB of customer information in both JSON and CSV formats.

Instead of isolated details, the breach reportedly includes highly sensitive data: full names, dates of birth, tax IDs, physical and email addresses, device and cookie identifiers, phone numbers, and IP addresses.

Cybersecurity firm DarkEye flagged the leak, warning that the structured formats make the data easy for criminals to exploit.

If verified, the breach would mark yet another major incident for AT&T. In March 2024, the company confirmed that personal information from 73 million users had been leaked.

Just months later, a July breach exposed call records and location metadata for nearly 110 million customers, with blame directed at compromised Snowflake cloud accounts.

AT&T has yet to comment on the latest claims. Experts warn that the combination of tax numbers and device data could enable identity theft, financial scams, and advanced phishing attacks.

For a company already under scrutiny for past security lapses, the latest breach could further damage public trust.

Libra meme coin wallets frozen on Solana

Two wallets tied to the controversial Libra meme coin team have been frozen. Nearly $58 million in USDC stablecoins on the Solana blockchain are now locked.

The freeze on Solscan affects accounts holding $44.59 million and $13.06 million in USDC, a stablecoin issued by Circle. Major stablecoin issuers like Circle have the authority to blacklist addresses in cases of fraud or legal disputes.

The freeze follows a temporary restraining order from a US federal court, requested by Burwick Law amid ongoing litigation. Argentina’s justice department has also been linked to the legal action, connected to the Libra token promoted by Argentine President Javier Milei.

The token’s rapid rise and fall earlier this year sparked accusations of a pump-and-dump scheme.

Despite the legal troubles, Circle has recently filed for an initial public offering on the New York Stock Exchange, aiming for a $6.7 billion valuation. Meanwhile, Argentina’s task force investigating the scandal was disbanded last week.

Victoria’s Secret website hit by cyber attack

Victoria’s Secret’s website has remained offline for three days due to a security incident the company has yet to fully explain. A spokesperson confirmed steps are being taken to address the issue, saying external experts have been called in and some in-store systems were also taken down as a precaution.

Instead of revealing specific details, the retailer has left users with only a holding message on a pink background. It has declined to comment on whether ransomware is involved, when the disruption began, or if law enforcement has been contacted.

The firm’s physical stores continue operating as normal, and payment systems are unaffected, suggesting the breach has hit other digital infrastructure. Still, the shutdown has rattled investors—shares fell nearly seven percent on Wednesday.

With online sales accounting for a third of Victoria’s Secret’s $6 billion annual revenue, the pressure to resolve the situation is high.

The timing has raised eyebrows, as cybercriminals often strike during public holidays like Memorial Day, when IT teams are short-staffed. The attack follows a worrying trend among retailers.

UK giants such as Harrods, Marks & Spencer, and the Co-op have all suffered recent breaches. Experts warn that US chains are becoming the next major targets, with threat groups like Scattered Spider shifting their focus across the Atlantic.

UK and EU strengthen maritime and cyber security

The UK and the EU have agreed to step up cooperation on cybersecurity as part of a wider defence and security pact.

The new framework, signed on 19 May, marks a major shift towards joint efforts in countering digital threats and hybrid warfare.

Instead of managing these challenges separately, the UK and EU will hold structured dialogues to address cyberattacks, disinformation campaigns, and other forms of foreign interference.

The deal outlines regular exchanges between national security officials, supported by thematic discussions focused on crisis response, infrastructure protection, and online misinformation.

A key aim is to boost resilience against hostile cyber activity by working together on detection, defence, and prevention strategies. The agreement encourages joint efforts to safeguard communication networks, protect energy grids, and strengthen public awareness against information manipulation.

The cooperation is expected to extend into coordinated drills and real-time threat sharing.

While the UK remains outside the EU’s political structure, the agreement positions it as a close cyber security partner.

Future plans include exploring deeper collaboration through EU defence projects and potentially forming a formal link with the European Defence Agency, ensuring that both sides can respond more effectively to emerging digital threats.

ABCI-Q goes live as Japan ramps up quantum tech investment

Japan has officially launched the world’s most powerful supercomputer dedicated to quantum computing research. Known as ABCI-Q, the system is housed within the newly opened G-QuAT research centre in Tsukuba, operated by the National Institute of Advanced Industrial Science and Technology (AIST).

G-QuAT (Global Research and Development Centre for Business by Quantum-AI Technology) opened earlier this month with a mission to advance hybrid computing technologies that combine classical computing, such as AI, with quantum systems.

Its work is structured around three main goals: developing use cases for hybrid computing, supporting the quantum technology supply chain, and enabling large-scale qubit integration.

ABCI-Q runs on 2,020 Nvidia H100 GPUs, connected using Nvidia’s Quantum-2 InfiniBand architecture, and integrated with CUDA-Q, Nvidia’s hybrid orchestration platform.

It supports multiple quantum processors, including superconducting qubits from Fujitsu, a neutral atom system by QuEra, and a photonic processor by OptQC—enabling diverse hybrid workloads across different qubit technologies.

The machine’s infrastructure includes 18 cryogenic systems supplied by Bluefors, built to support quantum computers with 1,000+ qubits and thousands of signal paths. G-QuAT has also partnered with IonQ to access its quantum systems via the cloud, bolstering research access and global collaboration.

The launch of ABCI-Q underscores Japan’s ambition to lead in next-generation computing. The government of Japan has committed over ¥330 billion (£1.7 billion) to quantum initiatives between 2020 and 2024.

AIST says the project aims to boost national industrial competitiveness, expand scientific capabilities, and foster a skilled quantum workforce.

The EU probes porn sites over DSA violations

The European Commission has launched a formal investigation into four major pornographic websites—Pornhub, Stripchat, XNXX, and XVideos—over concerns they may be violating the EU’s Digital Services Act (DSA). The probe centres on whether these platforms provide adequate protection for minors, notably regarding age verification.

According to the Commission, all four currently use simple click-through age checks, which are suspected of failing to meet DSA requirements. Authorities primarily focus on assessing whether the platforms have conducted proper risk assessments and implemented safeguards to protect children’s mental and physical health.

The European Commission emphasised that the investigation is a priority and will include collaboration with the EU member states to monitor smaller adult sites that fall under the 45-million-user threshold. In its statement, the Commission reiterated plans to roll out a standardised EU-wide age verification system by the end of next year.

While Pornhub, XVideos, and Stripchat were previously designated as Very Large Online Platforms (VLOPs), the Commission announced on Tuesday that Stripchat will no longer hold that status moving forward.

EMSA given broader powers for digital maritime threats

The European Maritime Safety Agency (EMSA) is set to take on an expanded role in maritime security, following a provisional agreement between the European Parliament and the Council.

Instead of focusing solely on traditional safety tasks, EMSA will now help tackle modern challenges, including cyber attacks and hybrid threats that increasingly target critical maritime infrastructure across Europe.

The updated mandate enables EMSA to support EU member states and the European Commission with technical, operational and scientific assistance in areas such as cybersecurity, pollution response, maritime surveillance and decarbonisation.

Rather than remaining confined to its original scope, the agency may also adopt new responsibilities as risks evolve, provided such tasks are requested by the Commission or individual countries.

The move forms part of a broader EU legislative package aimed at reinforcing maritime safety rules, improving environmental protections and updating inspection procedures.

The reforms ensure EMSA is equipped with adequate human and financial resources to handle its wider remit and contribute to strategic resilience in an increasingly digital and geopolitically unstable world.

Created in 2002 and based in Lisbon, EMSA plays a central role in safeguarding maritime transport, which remains vital for Europe’s economy and trade.

With more than 2,000 marine incidents reported annually, the agency’s modernised mandate is expected to strengthen the EU’s ability to prevent disruptions at sea and support its broader green and security goals.

The EU lawmakers investigate Italian surveillance case

A delegation from the European Parliament’s Civil Liberties, Justice and Home Affairs Committee (LIBE) will visit Rome on 30 May to examine the unfolding controversy surrounding the use of Paragon’s spyware in Italy.

The mission will be led by Sandro Ruotolo, a member of the European Parliament, and will include meetings with surveillance victims, press representatives, and members of the parliamentary committee responsible for intelligence oversight, known as COPASIR.

The Israeli-developed surveillance software, Graphite, produced by Paragon, is at the centre of the investigation. Reports allege that the tool was used to monitor investigative journalists and NGO activists in Italy, sparking national concern and leading to the termination of Italy’s agreement with the company.

Despite public pressure for clarity, the Italian government has declined to release additional information, stating that any clarifications would be delivered exclusively to COPASIR, which is currently evaluating the claims.

Taiwan rebuffs China’s hacking claims as disinformation

Taiwan has rejected accusations from Beijing that its ruling party orchestrated cyberattacks against Chinese infrastructure. Authorities in Taipei instead accused China of spreading false claims in an effort to manipulate public perception and escalate tensions.

On Tuesday, Chinese officials alleged that a Taiwan-backed hacker group linked to the Democratic Progressive Party (DPP) had targeted a technology firm in Guangzhou.

They claimed more than 1,000 networks, including systems tied to the military, energy, and government sectors, had been compromised across ten provinces in recent years.

Taiwan’s National Security Bureau responded on Wednesday, stating that the Chinese Communist Party is manipulating false information to mislead the international community.

Rather than acknowledging its own cyber activities, Beijing is attempting to shift blame while undermining Taiwan’s credibility, the agency said.

Taipei further accused China of long-running cyberattacks aimed at stealing funds and destabilising critical infrastructure. Officials described such campaigns as part of cognitive warfare designed to widen social divides and erode public trust within Taiwan.
