Massive leak exposes data of millions in China

Cybersecurity researchers have uncovered a brief but significant leak of over 600 gigabytes of data, exposing information on millions of Chinese citizens.

The haul, containing WeChat, Alipay, banking, and residential records, is part of a centralised system, possibly aimed at large-scale surveillance instead of a random data breach.

According to research from Cybernews and cybersecurity consultant Bob Diachenko, the data was likely used to build individuals’ detailed behavioural, social and economic profiles.

They warned the information could be exploited for phishing, fraud, blackmail or even disinformation campaigns instead of remaining dormant. Although only 16 datasets were reviewed before the database vanished, they indicated a highly organised and purposeful collection effort.

The source of the leak remains unknown, but the scale and nature of the data suggest it may involve government-linked or state-backed entities rather than lone hackers.

The exposed information could allow malicious actors to track residence locations, financial activity and personal identifiers, placing millions at risk instead of keeping their lives private and secure.

Digital Social Security cards coming this summer

The US Social Security Administration is launching digital access to Social Security numbers in the summer of 2025 through its ‘My Social Security’ portal. The initiative aims to improve convenience, reduce physical card replacement delays, and protect against identity theft.

The digital rollout responds to the challenges of outdated paper cards, rising fraud risks, and growing demand for remote access to US government services. Cybersecurity experts also recommend using VPNs, antivirus software, and identity monitoring services to guard against phishing scams and data breaches.

While it promises faster and more secure access, experts urge users to bolster account protection through strong passwords, two-factor authentication, and avoidance of public Wi-Fi when accessing sensitive data.

Users should regularly check their credit reports and SSA records and consider requesting an IRS PIN to prevent tax-related fraud. The SSA says this move will make Social Security more efficient without compromising safety.

Trump Executive Order revises US cyber policy and sanctions scope

US President Donald J. Trump signed a new Executive Order (EO) aimed at amending existing federal cybersecurity policies. The EO modifies selected provisions of previous executive orders signed by former Presidents Barack Obama and Joe Biden, introducing updates to sanctions policy, digital identity initiatives, and secure technology practices.

One of the main changes involves narrowing the scope of sanctions related to malicious cyber activity. The new EO limits the applicability of such sanctions to foreign individuals or entities involved in cyberattacks against US critical infrastructure. It also states that sanctions do not apply to election-related activities, though this clarification is included in a White House fact sheet rather than the EO text itself.

The order revokes provisions from the Biden-era EO that proposed expanding the use of federal digital identity documents, including mobile driver’s licenses. According to the fact sheet, this revocation is based on concerns regarding implementation and potential for misuse. Some analysts have expressed concerns about the implications of this reversal on broader digital identity strategies.

In addition to these policy revisions, the EO outlines technical measures to strengthen cybersecurity capabilities across federal agencies. These include:

  • Developing new encryption standards to prepare for advances in quantum computing, with implementation targets set for 2030.
  • Directing the National Security Agency (NSA) and Office of Management and Budget (OMB) to issue updated federal encryption requirements.
  • Refocusing artificial intelligence (AI) and cybersecurity initiatives on identifying and mitigating vulnerabilities.
  • Assigning the National Institute of Standards and Technology (NIST) responsibility for updating and guiding secure software development practices. This includes the establishment of an industry consortium and a preliminary update to its secure software development framework.

The EO also includes provisions for improving vulnerability tracking and mitigation in AI systems, with coordination required among the Department of Defence, the Department of Homeland Security, and the Office of the Director of National Intelligence.

Cybersecurity alarm after 184 million credentials exposed

A vast unprotected database containing over 184 million credentials from major platforms and sectors has highlighted severe weaknesses in data security worldwide.

The leaked credentials, harvested by infostealer malware and stored in plain text, pose significant risks to consumers and businesses, underscoring an urgent need for stronger cybersecurity and better data governance.

Cybersecurity researcher Jeremiah Fowler discovered the 47 GB database exposing emails, passwords, and authorisation URLs from tech giants like Google, Microsoft, Apple, Facebook, and Snapchat, as well as banking, healthcare, and government accounts.

The data was left accessible without any encryption or authentication, making it vulnerable to anyone with the link.

The credentials were reportedly collected by infostealer malware such as Lumma Stealer, which silently steals sensitive information from infected devices. The stolen data fuels a thriving underground economy involving identity theft, fraud, and ransomware.

The breach’s scope extends beyond tech, affecting critical infrastructure like healthcare and government services, raising concerns over personal privacy and national security. With recurring data breaches becoming the norm, industries must urgently reinforce security measures.

Chief Data Officers and IT risk leaders face mounting pressure as regulatory scrutiny intensifies. The leak highlights the need for proactive data stewardship through encryption, access controls, and real-time threat detection.

Many organisations struggle with legacy systems, decentralised data, and cloud adoption, complicating governance efforts.

Enterprise leaders must treat data as a strategic asset and liability, embedding cybersecurity into business processes and supply chains. Beyond technology, cultivating a culture of accountability and vigilance is essential to prevent costly breaches and protect brand trust.

The massive leak signals a new era in data governance where transparency and relentless improvement are critical. The message is clear: there is no room for complacency in safeguarding the digital world’s most valuable assets.

FBI warns BADBOX 2.0 malware is infecting millions

The FBI has issued a warning about the resurgence of BADBOX 2.0, a dangerous form of malware infecting millions of consumer electronics globally.

Often preloaded onto low-cost smart TVs, streaming boxes, and IoT devices, primarily from China, the malware grants cyber criminals backdoor access, enabling theft, surveillance, and fraud while remaining essentially undetectable.

BADBOX 2.0 forms part of a massive botnet and can also infect devices through malicious apps and drive-by downloads, especially from unofficial Android stores.

Once activated, the malware enables a range of attacks, including click fraud, fake account creation, DDoS attacks, and the theft of one-time passwords and personal data.

Removing the malware is extremely difficult, as it typically requires flashing new firmware, an option unavailable for most of the affected devices.

Users are urged to check their hardware against a published list of compromised models and to avoid sideloading apps or purchasing unverified connected tech.

M&S CEO targeted by hackers in abusive ransom email

Marks & Spencer has been directly targeted by a ransomware group calling itself DragonForce, which sent a vulgar and abusive ransom email to CEO Stuart Machin using a compromised employee email address.

The message, laced with offensive language and racist terms, demanded that Machin engage via a darknet portal to negotiate payment. It also claimed that the hackers had encrypted the company’s servers and stolen customer data, a claim M&S eventually acknowledged weeks later.

The email, dated 23 April, appears to have been sent from the account of an Indian IT worker employed by Tata Consultancy Services (TCS), a long-standing M&S tech partner.

TCS has denied involvement and stated that its systems were not the source of the breach. M&S has remained silent publicly, neither confirming the full scope of the attack nor disclosing whether a ransom was paid.

The cyber attack has caused major disruption, costing M&S an estimated £300 million and halting online orders for over six weeks.

DragonForce has also claimed responsibility for a simultaneous attack on the Co-op, which left some shelves empty for days. While nothing has yet appeared on DragonForce’s leak site, the group claims it will publish stolen information soon.

Investigators believe DragonForce operates as a ransomware-as-a-service collective, offering tools and platforms to cybercriminals in exchange for a 20% share of any ransom.

Some experts suspect the real perpetrators may be young hackers from the West, linked to a loosely organised online community called Scattered Spider. The UK’s National Crime Agency has confirmed it is focusing on the group as part of its inquiry into the recent retail hacks.

Google warns users to switch to passkeys after new phishing attacks

Google is once again urging users to upgrade their account security by moving away from password-only access, as cyber scams grow increasingly sophisticated.

The warning follows an attempted phishing attack on Instagram boss Adam Mosseri, who revealed he had been targeted by a convincing scam involving a fake Google phone call and a seemingly legitimate email prompting him to change his password.

Though Google quickly traced and suspended the accounts involved, the incident highlights the evolving nature of online threats. The company has reiterated that it never contacts users by phone or email about password changes or account issues. Any such message should be considered a scam.

In response, Google is encouraging users to adopt stronger security methods, such as Passkeys—a login system that replaces passwords with biometric authentication via a trusted device like a smartphone. This can include fingerprint recognition, facial scan, or the phone’s screen lock.

The tech giant also recommends using two-factor authentication (2FA), but advises against relying on SMS codes or email-based verification, which can be intercepted. Instead, users should opt for an authentication app or use Passkeys for greater protection.

With scams becoming more difficult to detect, Google’s message is clear: take proactive steps to secure your account. Users who receive suspicious communication claiming to be from Google are advised to avoid engaging and verify concerns through Google’s official support channels.

Gmail accounts at risk as attacks rise

Google has urged Gmail users to upgrade their account security after revealing that over 60% have been targeted by cyberattacks. Despite the increasing threat, most people still rely on outdated protections like passwords and SMS-based two-factor authentication.

Google is now pushing users to adopt passkeys and social sign-ins to improve their defences. Passkeys offer phishing-resistant access and use biometric methods such as fingerprint or facial recognition tied to a user’s device, removing the need for traditional passwords.

While digitally savvy Gen Z users are more likely to adopt these new methods, but many still reuse passwords, leaving their accounts exposed to breaches and scams. Google emphasised that passwords are both insecure and inconvenient and called on users to switch to tools that offer stronger protection.

Microsoft, meanwhile, has gone even further by encouraging users to eliminate passwords entirely. Google’s long-term goal is to simplify sign-ins while increasing security across its platforms.

Europe gets new cybersecurity support from Microsoft

Microsoft has launched a free cybersecurity initiative for European governments aimed at countering increasingly sophisticated cyber threats powered by AI. Company President Brad Smith said Europe would benefit from tools already developed and deployed in the US.

The programme is designed to identify and disrupt AI-driven threats, including deepfakes and disinformation campaigns, which have previously been used to target elections and undermine public trust.

Smith acknowledged that AI is a double-edged sword, with malicious actors exploiting it for attacks, while defenders increasingly use it to stay ahead. Microsoft continues to monitor how its AI products are used, blocking known cybercriminals and working to ensure AI serves as a stronger shield than weapon.

Salt Typhoon and Silk Typhoon reveal weaknesses

Recent revelations about Salt Typhoon and Silk Typhoon have exposed severe weaknesses in how organisations secure their networks.

These state-affiliated hacking groups have demonstrated that modern cyber threats come from well-resourced and coordinated actors instead of isolated individuals.

Salt Typhoon, responsible for one of the largest cyber intrusions into US infrastructure, exploited cloud network vulnerabilities targeting telecom giants like AT&T and Verizon, forcing companies to reassess their reliance on traditional private circuits.

Many firms continue to believe private circuits offer better protection simply because they are off the public internet. Some even add MACsec encryption for extra defence. However, MACsec’s ‘hop-by-hop’ design introduces new risks—data is repeatedly decrypted and re-encrypted at each routing point.

Every one of these hops becomes a possible target for attackers, who can intercept, manipulate, or exfiltrate data without detection, especially when third-party infrastructure is involved.

Beyond its security limitations, MACsec presents high operational complexity and cost, making it unsuitable for today’s cloud-first environments. In contrast, solutions like Internet Protocol Security (IPSec) offer simpler, end-to-end encryption.

Although not perfect in cloud settings, IPSec can be enhanced through parallel connections or expert guidance. The Cybersecurity and Infrastructure Security Agency (CISA) urges organisations to prioritise complete encryption of all data in transit, regardless of the underlying network.

Silk Typhoon has further amplified concerns by exploiting privileged credentials and cloud APIs to infiltrate both on-premise and cloud systems. These actors use covert networks to maintain long-term access while remaining hidden.

As threats evolve, companies must adopt Zero Trust principles, strengthen identity controls, and closely monitor their cloud environments instead of relying on outdated security models.

Collaborating with cloud security experts can help shut down exposure risks and protect sensitive data from sophisticated and persistent threats.
