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.

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.

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.

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.
