China accuses Taiwan of cyber attacks and offers a bounty

Authorities in Guangzhou have placed a secret bounty on more than 20 individuals suspected of launching cyber attacks on Chinese targets, according to state news agency Xinhua.

One named suspect, Ning Enwei, is reportedly linked to Taiwan’s government. While the size of the reward remains undisclosed, officials claim the accused hackers targeted sectors including defence, aerospace, energy, and science—alongside agencies in Hong Kong and Macau.

Xinhua stated that Taiwan’s ‘information, communication and digital army’ has coordinated with US forces to carry out cyber and cognitive warfare against China.

These accusations form part of a broader Chinese narrative suggesting Taiwan is seeking independence through foreign alliances, particularly with US intelligence agencies. State media also claimed the US has trained Taiwanese personnel and helped orchestrate cyber attacks on the mainland.

In response, a senior Taiwanese security official, speaking anonymously, dismissed the claims as fabricated. The official argued that Beijing is attempting to deflect criticism following allegations of Chinese cyber activities in Europe, especially in the Czech Republic.

‘It is typical of the Chinese Communist Party’s efforts to change the narrative,’ the official said, branding Beijing an international cyber threat instead of a victim.

Taiwan’s government has yet to issue an official statement.

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.

HMRC got targeted in a £47 million UK fraud

A phishing scheme run by organised crime groups cost the UK government £47 million, according to officials from His Majesty’s Revenue and Customs.

Criminals posed as taxpayers to claim payments using fake or hijacked credentials. Rather than a cyberattack, the operation relied on impersonation and did not involve the theft of taxpayer data.

Angela MacDonald, HMRC’s deputy chief executive, confirmed to Parliament’s Treasury Committee that the fraud took place in 2024. The stolen funds were taken through three separate payments, though HMRC managed to block an additional £1.9 million attempt.

Officials began a cross-border criminal investigation soon after discovering the scam, which has led to arrests.

Around 100,000 PAYE accounts — typically used by employers for employee tax and national insurance payments — were either created fraudulently or accessed illegally.

Banks were also targeted through the use of HMRC-linked identity information. Customers first flagged the issue when they noticed unusual activity.

HMRC has shut down the fake accounts and removed false data as part of its response. John-Paul Marks, HMRC’s chief executive, assured the committee that the incident is now under control and contained. ‘That is a lot of money and unacceptable,’ MacDonald told MPs.

Cyber attack hits Lee Enterprises staff data

Thousands of current and former employees at Lee Enterprises have had their data exposed following a cyberattack earlier this year.

Hackers accessed to the company’s systems in early February, compromising sensitive information such as names and Social Security numbers before the breach was contained the same day.

Although the media firm, which operates over 70 newspapers across 26 US states, swiftly secured its networks, a three-month investigation involving external cybersecurity experts revealed that attackers accessed databases containing employee details.

The breach potentially affects around 40,000 individuals — far more than the company’s 4,500 current staff — indicating that past employees were also impacted.

The stolen data could be used for identity theft, fraud or phishing attempts. Criminals may even impersonate affected employees to infiltrate deeper into company systems and extract more valuable information.

Lee Enterprises has notified those impacted and filed relevant disclosures with authorities, including the Maine Attorney General’s Office.

Headquartered in Iowa, Lee Enterprises draws over 200 million monthly online page views and generated over $611 million in revenue in 2024. The incident underscores the ongoing vulnerability of media organisations to cyber threats, especially when personal employee data is involved.

Vodafone fined €45 million in Germany over data privacy violations

German data protection authorities have imposed a €45 million ($51.2 million) fine on Vodafone for what they described as serious data privacy breaches involving both third-party sales practices and weak digital security systems. The Federal Commissioner for Data Protection (BfDI) cited ‘malicious behaviour’ by partner agencies and security flaws that allowed unauthorised access to customer accounts.

Investigators found that some of Vodafone’s partner agencies engaged in fraudulent conduct, including altering or forging contracts to the detriment of customers. Vodafone was fined €15 million for failing to properly supervise these partners, as required by the European Union’s General Data Protection Regulation (GDPR).

Additionally, a €30 million fine was levied due to vulnerabilities in Vodafone’s customer authentication systems, which potentially allowed outsiders to access sensitive services like eSIM profiles. Vodafone has acknowledged the issues, attributing them to inadequate data protection checks at the time.

The company expressed regret for the impact on customers and emphasized that under new management, it has overhauled its data protection protocols to prevent future breaches.

Louisa Specht-Riemenschneider, Germany’s federal data protection commissioner, underscored the importance of data security, stating that user trust in digital services depends on strong safeguards. She added that proper compliance can even be a competitive advantage, as EU regulators continue to crack down on companies that violate GDPR standards.

Cyber attacks and ransomware rise globally in early 2025

Cyber attacks have surged by 47% globally in the first quarter of 2025, with organisations facing an average of 1,925 attacks each week.

Check Point Software, a cybersecurity firm, warns that attackers are growing more sophisticated and persistent, targeting critical sectors like healthcare, finance, and technology with increasing intensity.

Ransomware activity alone has soared by 126% compared to last year. Attackers are no longer just encrypting files but now also threaten to leak sensitive data unless paid — a tactic known as dual extortion.

Instead of operating as large, centralised gangs, modern ransomware groups are smaller and more agile, often coordinating through dark web forums, making them harder to trace.

The report also notes that cybercriminals are using AI to automate phishing attacks and scan systems for vulnerabilities, allowing them to strike with greater accuracy. Emerging markets remain particularly vulnerable, as they often lack advanced cybersecurity infrastructure.

Check Point urges companies to act decisively by adopting proactive security measures, investing in threat detection and employee training, and implementing real-time monitoring. Waiting for an attack instead of preparing in advance could leave organisations dangerously exposed.

Customer data stolen in cyber attacks on Cartier and North Face

Fashion brand The North Face and luxury jeweller Cartier have confirmed recent cyber attacks that exposed customer data, including names and email addresses.

Neither company reported breaches of financial or password information.

North Face identified the attack as a credential stuffing attempt, where previously stolen passwords are used to break into other accounts.

Affected customers are being advised to change their login details, while the company’s owner, VF Corporation, continues recovering from an earlier incident.

Cartier said the breach allowed brief access to limited client data but insisted that it quickly secured its systems.

Retailers such as Adidas, Victoria’s Secret, Harrods, and M&S have all been hit in recent months, prompting warnings that the industry remains an attractive target for cyber criminals.

Microsoft and CrowdStrike align naming of threat actors

Microsoft and CrowdStrike have announced a joint initiative to align their threat actor taxonomies, aiming to improve clarity and coordination in the fight against cyberattacks.

While the two cybersecurity giants are not creating a unified naming standard, they are publishing a cross-referenced mapping that shows how threat actors tracked by both companies correspond under their respective naming systems.

The inconsistency in threat actor names across the cybersecurity industry has long created confusion, often slowing response times and complicating collaboration between teams.

A single actor might be known as Midnight Blizzard by Microsoft, Cozy Bear by another firm, and APT29 or UNC2452 by others — all referring to the same group. This fragmentation of identifiers has made tracking and defending against threats more difficult.

To address this, Microsoft and CrowdStrike have released a reference document that maps common threat actors across both organisations’ taxonomies and includes aliases from other vendors.

The goal is to provide security teams with a clearer understanding of which groups are being discussed, regardless of the terminology used.

Although the mapping effort currently involves only Microsoft and CrowdStrike, other major players in the cybersecurity industry — including Google’s Mandiant and Palo Alto Networks’ Unit 42 — are expected to contribute to the initiative in the future.

‘Security is a shared responsibility, requiring community-wide efforts to improve defensive measures,’ said Vasu Jakkal, Corporate Vice President of Microsoft Security. ‘We are excited to be teaming up with CrowdStrike and look forward to others joining us on this journey.’

As more companies adopt this collaborative approach, experts believe it will enhance collective defence by making threat intelligence easier to interpret and act upon across the security ecosystem.

WhatsApp fixes deleted message privacy gap

WhatsApp is rolling out a privacy improvement that ensures deleted messages no longer linger in quoted replies, addressing a long-standing issue that exposed partial content users had intended to remove.

The update applies automatically, with no toggle required, and has begun reaching iOS users through version 25.12.73, with wider availability expected soon.

Until now, deleting a message for everyone in a chat has not removed it from quoted replies. That allowed fragments of deleted content to remain visible, undermining the purpose of deletion.

WhatsApp removes the associated quoted message entirely instead of keeping it in conversation threads, even in group or community chats.

WABetaInfo, which first spotted the update, noted that users delete messages for privacy or personal reasons, and leave behind quoted traces conflicted with those intentions.

The change ensures conversations reflect user expectations by entirely erasing deleted content, not only from the original message but also from any references.

Meta continues to develop new features for WhatsApp. Recent additions include voice chat in groups and a native interface for iPad. The company is also testing tools like AI-generated wallpapers, message summaries, and more refined privacy settings to enhance user control and experience further.

NSO asks court to overturn WhatsApp verdict

Israeli spyware company NSO Group has requested a new trial after a US jury ordered it to pay $168 million in damages to WhatsApp.

The company, which has faced mounting legal and financial troubles, filed a motion in a California federal court last week seeking to reduce the verdict or secure a retrial.

The May verdict awarded WhatsApp $444,719 in compensatory damages and $167.25 million in punitive damages. Jurors found that NSO exploited vulnerabilities in the encrypted platform and sold the exploit to clients who allegedly used it to target journalists, activists and political rivals.

WhatsApp, owned by Meta, filed the lawsuit in 2019.

NSO claims the punitive award is unconstitutional, arguing it is over 376 times greater than the compensatory damages and far exceeds the US Supreme Court’s general guidance of a 4:1 ratio.

The firm also said it cannot afford the penalty, citing losses of $9 million in 2023 and $12 million in 2024. Its CEO testified that the company is ‘struggling to keep our heads above water’.

WhatsApp, responding to TechCrunch in a statement, said NSO was once again trying to evade accountability. The company vowed to continue its legal campaign, including efforts to secure a permanent injunction that would prevent NSO from ever targeting WhatsApp or its users again.
