Massive data leak exposes 16 billion login credentials from Google, Facebook, and more

One of the largest-ever leaks of stolen login data has come to light, exposing more than 16 billion records across widely used services, including Facebook, Google, Telegram, and GitHub. The breach, uncovered by researchers at Cybernews, highlights a growing threat to individuals and organisations.

The exposed data reportedly originated from info stealer malware, previous leaks, and credential-stuffing tools. A total of 30 separate datasets were identified, some containing over 3.5 billion entries.

These were briefly available online due to unsecured cloud storage before being removed. Despite the swift takedown, the data had already been collected and analysed.

Experts have warned that the breach could lead to identity theft, phishing, and account takeovers. Smaller websites and users with poor cybersecurity practices are especially vulnerable. Many users continue to reuse passwords or minor variations of them, increasing the risk of exploitation.

While the leak is severe, users employing two-factor authentication (2FA), password managers, or passkeys are less likely to be affected.

Passkeys, increasingly adopted by companies like Google and Apple, offer a phishing-resistant login method that bypasses the need for passwords altogether.

Iran enforces crypto exchange curfew after Nobitex breach

Iran’s central bank has imposed strict operating hours on domestic crypto exchanges following a massive $100 million hack on Nobitex, the country’s largest digital asset platform. The move comes amid accusations that the incident was politically motivated.

According to blockchain analytics firm Chainalysis, exchanges in Iran are now required to operate between 10 am and 8 pm only. Analysts believe the curfew is aimed at improving monitoring capabilities and limiting capital flight during heightened Iran-Israel hostilities.

Andrew Fierman, head of national security intelligence at Chainalysis, suggested the decision was both a technical response to the hack and a strategic move to maintain tighter control over outflows.

The cyberattack, allegedly orchestrated by pro-Israel group Predatory Sparrow, targeted Nobitex’s internal systems, draining hot wallets of Bitcoin, Ether, Dogecoin, XRP, and Solana.

Cybersecurity experts say the stolen assets were transferred to burner wallets without access keys, effectively destroying them in a rare politically charged crypto burn. Nobitex stated it has isolated its systems and will compensate users using its reserve fund.

Nobitex plays a crucial role in Iran’s crypto economy, having processed over $11 billion in inflows, far outpacing all other domestic exchanges. Chainalysis notes the platform also has ties to sanctioned entities and terrorist-linked groups.

The incident is one in a series of recent cyberattacks on Iranian infrastructure, suggesting a growing digital front in the long-standing Iran-Israel conflict.

Ryuk ransomware hacker extradited to US after arrest in Ukraine

A key member of the infamous Ryuk ransomware gang has been extradited to the US after his arrest in Kyiv, Ukraine.

The 33-year-old man was detained in April 2025 at the request of the FBI and arrived in the US on 18 June to face multiple charges.

The suspect played a critical role within Ryuk by gaining initial access to corporate networks, which he then passed on to accomplices who stole data and launched ransomware attacks.

Ukrainian authorities identified him during a larger investigation into ransomware groups like LockerGoga, Dharma, Hive, and MegaCortex that targeted companies across Europe and North America.

According to Ukraine’s National Police, forensic analysis revealed the man’s responsibility for locating security flaws in enterprise networks.

Information gathered by the hacker allowed others in the gang to infiltrate systems, steal data, and deploy ransomware payloads that disrupted various industries, including healthcare, during the COVID pandemic.

Ryuk operated from 2018 until mid-2020 before rebranding as the notorious Conti gang, which later fractured into several smaller but still active groups. Researchers estimate that Ryuk alone collected over $150 million in ransom payments before shutting down.

Hacktivists target Iran’s Bank Sepah in major cyberattack

A cyberattack has reportedly hit Iran’s Bank Sepah by the hacktivist group Predatory Sparrow. The group announced on Tuesday that it had ‘destroyed all data’ at the bank, which is closely linked to the Islamic Revolutionary Guard Corps (IRGC) and Iran’s military.

Several Bank Sepah branches were closed, and customers reported being unable to access their accounts.
The attack coincided with broader banking disruptions in Iran, affecting services at Kosar and Ansar banks, both associated with military entities and subject to US sanctions.

Authorities in Iran have yet to publicly acknowledge the attack, though the IRGC-linked Fars news agency claimed the issues would be resolved in a few hours.

Predatory Sparrow said it targeted Bank Sepah for its alleged role in financing Iran’s missile and nuclear programmes and in helping the country circumvent international sanctions.

The group has previously claimed responsibility for attacks on Iranian steel plants and fuel stations and is widely believed by Tehran to receive foreign support, particularly from Israel.

Bank Sepah, one of the country’s oldest financial institutions, operates around 1,800 branches within Iran and maintains offices across Europe. The United States sanctioned the bank in 2019 following Iran’s withdrawal from the 2015 nuclear deal.

Indonesia’s cyber push faces capacity challenges in the provinces

Indonesia is decentralising its approach to cybersecurity, launching eight regional Cyber Crime Directorates within provincial police forces in September 2024.

These directorates, located in areas including Jakarta, East Java, Bali, and Papua, aim to boost local responses to increasingly complex cyber threats—from data breaches and financial fraud to hacktivism and disinformation.

The move marks a shift from Jakarta-led cybersecurity efforts toward a more distributed model, aligning with Indonesia’s broader decentralisation goals. It reflects the state’s recognition that digital threats are not only national in scope, but deeply rooted in local contexts.

However, experts warn that regionalising cyber governance comes with significant challenges. Provincial police commands often lack specialised personnel, digital forensics capabilities, and adaptive institutional structures.

Many still rely on rotations from central agencies or basic training programs—insufficient for dealing with fast-moving and technically advanced cyberattacks.

Moreover, the culture of rigid hierarchy and limited cross-agency collaboration may further hinder rapid response and innovation at the local level. Without reforms to increase flexibility, autonomy, and inter-agency cooperation, these new directorates risk becoming symbolic rather than operationally impactful.

The inclusion of provinces like Central Sulawesi and Papua also reveals a political dimension. These regions are historically security-sensitive, and the presence of cyber directorates could serve both policing and state surveillance functions, raising concerns over the balance between security and civil liberties.

To be effective, the initiative requires more than administrative expansion. It demands sustained investment in talent development, modern infrastructure, and trusted partnerships with local stakeholders—including the private sector and academia.

If these issues are not addressed, Indonesia’s push to regionalise cybersecurity may reinforce old hierarchies rather than build meaningful local capacity. Stronger, smarter institutions—not just new offices—will determine whether Indonesia can secure its digital future.

Graphite spyware used against European reporters, experts warn

A new surveillance scandal has emerged in Europe as forensic evidence confirms that an Israeli spyware firm Paragon used its Graphite tool to target journalists through zero-click attacks on iOS devices. The attacks, requiring no user interaction, exposed sensitive communications and location data.

Citizen Lab and reports from Schneier on Security identified the spyware on multiple journalists’ devices on April 29, 2025. The findings mark the first confirmed use of Paragon’s spyware against members of the press, raising alarms over digital privacy and press freedom.

Backed by US investors, Paragon has operated outside of Israel under claims of aiding national security. But its spyware is now at the center of a widening controversy, particularly in Italy, where the government recently ended its contract with the company after two journalists were targeted.

Experts warn that such attacks undermine the confidentiality crucial to journalism and could erode democratic safeguards. Even Apple’s secure devices proved vulnerable, according to Bleeping Computer, highlighting the advanced nature of Graphite.

The incident has sparked calls for tighter international regulation of spyware firms. Without oversight, critics argue, tools meant for fighting crime risk being used to silence dissent and target civil society.

The Paragon case underscores the urgent need for transparency, accountability, and stronger protections in an age of powerful, invisible surveillance tools.

Smart machines, dark intentions: UN urges global action on AI threats

The United Nations has warned that terrorists could seize control of AI-powered vehicles to launch devastating attacks in public spaces. A new report outlines how extremists might exploit autonomous cars and drones to bypass traditional defences.

AI is also feared to be a tool for facial recognition targeting and mass ‘swarm’ assaults using aerial devices. Experts suggest that key parts of modern infrastructure could be turned against the public if hacked.

Britain’s updated counter-terrorism strategy now reflects these growing concerns, including the risk of AI-generated propaganda and detailed attack planning. The UN has called for immediate global cooperation to limit how such technologies can be misused.

Security officials maintain that AI also offers valuable tools in the fight against extremism, enabling quicker intelligence processing and real-time threat identification. Nonetheless, authorities have been urged to prepare for worst-case scenarios involving AI-directed violence.

New cyberattack method poses major threat to smart grids, study finds

A new study published in ‘Engineering’ highlights a growing cybersecurity threat to smart grids as they become more complex due to increased integration of distributed energy sources.

The research, conducted by Zengji Liu, Mengge Liu, Qi Wang, and Yi Tang, focuses on a sophisticated form of cyberattack known as a false data injection attack (FDIA) that targets data-driven algorithms used in smart grid operations.

As modern power systems adopt technologies like battery storage and solar panels, they rely more heavily on algorithms to manage energy distribution and grid stability. However, these algorithms can be exploited.

The study introduces a novel black-box FDIA method that injects false data directly at the measurement modules of distributed power supplies, using generative adversarial networks (GANs) to produce stealthy attack vectors.

What makes this method particularly dangerous is that it doesn’t require detailed knowledge of the grid’s internal workings, making it more practical and harder to detect in real-world scenarios.

The researchers also proposed an approach to estimate controller and filter parameters in distributed energy systems, making it easier to launch these attacks.

To test the method, the team simulated attacks on the New England 39-bus system, specifically targeting a deep learning model used for transient stability prediction. Results showed a dramatic drop in accuracy—from 98.75% to 56%—after the attack.

The attack also proved effective across multiple neural network models and on larger grid systems, such as IEEE’s 118-bus and 145-bus networks.

These findings underscore the urgent need for better cybersecurity defenses in the evolving smart grid landscape. As systems grow more complex and reliant on AI-driven management, developing robust protection against FDIA threats will be critical.

Taiwan tightens rules on chip shipments to China

Taiwan has officially banned the export of chips and chiplets to China’s Huawei and SMIC, joining the US in tightening restrictions on advanced semiconductor transfers.

The decision follows reports that TSMC, the world’s largest contract chipmaker, was unknowingly misled into supplying chiplets used in Huawei’s Ascend 910B AI accelerator. The US Commerce Department had reportedly considered a fine of over $1 billion against TSMC for that incident.

Taiwan’s new rules aim to prevent further breaches by requiring export permits for any transactions with Huawei or SMIC.

The distinction between chips and chiplets is key to the case. Traditional chips are built as single-die monoliths using the same process node, while chiplets are modular and can combine various specialised components, such as CPU or AI cores.

Huawei allegedly used shell companies to acquire chiplets from TSMC, bypassing existing US restrictions. If TSMC had known the true customer, it likely would have withheld the order. Taiwan’s new export controls are designed to ensure stricter oversight of future transactions and prevent repeat deceptions.

The broader geopolitical stakes are clear. Taiwan views the transfer of advanced chips to China as a national security threat, given Beijing’s ambitions to reunify with Taiwan and the potential militarisation of high-end semiconductors.

With Huawei claiming its processors are nearly on par with Western chips—though analysts argue they lag two to three generations behind—the export ban could further isolate China’s chipmakers.

Speculation persists that Taiwan’s move was partly influenced by negotiations with the US to avoid the proposed fine on TSMC, bringing both countries into closer alignment on chip sanctions.

Turing Institute urges stronger AI research security

The Alan Turing Institute has warned that urgent action is needed to protect the UK’s AI research from espionage, intellectual property theft and risky international collaborations.

Its Centre for Emerging Technology and Security (CETaS) has published a report calling for a culture shift across academia to better recognise and mitigate these risks.

The report highlights inconsistencies in how security risks are understood within universities and a lack of incentives for researchers to follow government guidelines. Sensitive data, the dual-use potential of AI, and the risk of reverse engineering make the field particularly vulnerable to foreign interference.

Lead author Megan Hughes stressed the need for a coordinated response, urging government and academia to find the right balance between academic freedom and security.

The report outlines 13 recommendations, including expanding support for academic due diligence and issuing clearer guidance on high-risk international partnerships.

Further proposals call for compulsory research security training, better threat communication from national agencies, and standardised risk assessments before publishing AI research.

The aim is to build a more resilient research ecosystem as global interest in UK-led AI innovation continues to grow.
