Medical group hit with £100,000 penalty after cyberattack exposes patient data

Emails containing sensitive health data were stolen from the Medical Specialist Group (MSG) in a 2021 cyberattack. The data has been later used in phishing campaigns, prompting the Office of the Data Protection Authority (ODPA) to fine MSG £100,000 for insufficiently safeguarding personal data and breaching data protection legislation.

Investigators found the clinic’s email server was compromised in August 2021 and went undetected for more than three months. Health data is sensitive information that requires stringent protection. However, the ODPA found MSG neglected to install routine security updates for thirteen months, and weaknesses in its threat-detection system led to multiple missed chances to identify unauthorised access to its email server.

The ODPA has ordered MSG to pay £75,000 within 60 days and a further £25,000 after 14 months, with the final amount being waived if it completes an agreed security action plan. MSG stated it has invested in new technology, system monitoring and staff training. The exact number of stolen emails remains unclear, though thousands were left exposed to unauthorised access.

The breach adds to a growing list of cyberattacks targeting the healthcare sector over the past year, including incidents like the Anne Arundel Dermatology cyberattack affecting nearly two million patients and the McLaren Health Care ransomware attack, affecting over 700,000 individuals.

AWS outage turned a mundane DNS slip into global chaos

Cloudflare’s boss summed up the mood after Monday’s chaos, relieved his firm wasn’t to blame as outages rippled across more than 1,000 companies. Snapchat, Reddit, Roblox, Fortnite, banks, and government portals faltered together, exposing how much of the web leans on Amazon Web Services.

AWS is the backbone for a vast slice of the internet, renting compute, storage, and databases so firms avoid running their own stacks. However, a mundane Domain Name System error in its Northern Virginia region scrambled routing, leaving services online yet unreachable as traffic lost its map.

Engineers call it a classic failure mode: ‘It’s always DNS.’ Misconfigurations, maintenance slips, or server faults can cascade quickly across shared platforms. AWS says teams moved to mitigate, but the episode showed how a small mistake at scale becomes a global headache in minutes.

Experts warned of concentration risk: when one hyperscaler stumbles, many fall. Yet few true alternatives exist at AWS’s scale beyond Microsoft Azure and Google Cloud, with smaller rivals from IBM to Alibaba, and fledgling European plays, far behind.

Calls for UK–EU cloud sovereignty are growing, but timelines and costs are steep. Monday’s outage is a reminder that resilience needs multi-region and multi-cloud designs, tested failovers, and clear incident comms, not just faith in a single provider.

AWS outage shows the cost of cloud concentration

A single fault can bring down the modern web. During the outage on Monday, 20 October 2025, millions woke to broken apps, games, banking, and tools after database errors at Amazon Web Services rippled outward. When a shared backbone stumbles, the blast radius engulfs everything from chat to commerce.

The outage underscored cloud concentration risk. Roblox, Fortnite, Pokémon Go, Snapchat, and workplace staples like Slack and Monday.com stumbled together because many depend on the same region and data layer. Failover, throttling, and retries help, but simultaneous strain can swamp safeguards.

On Friday, 19 July 2024, a faulty CrowdStrike update crashed Windows machines worldwide, triggering blue screens that grounded flights, delayed surgeries, and froze point-of-sale systems. The fix was simple; recovery wasn’t. Friday patches gained a new cautionary tale.

Earlier shocks foreshadowed today’s scale. In 1997, a Network Solutions glitch briefly hobbled .com and .net. In 2018, malware in Alaska’s Matanuska-Susitna knocked services offline, sending a community of 100,000 back to paper. Each incident showed how mundane errors cascade into civic life.

Resilience now means multi-region designs, cross-cloud failovers, tested runbooks, rate-limit backstops, and graceful read-only modes. Add regulatory stress tests, clear incident comms, and sector drills with hospitals, airlines, and banks. The internet will keep breaking; our job is to make it bend.

SMEs underinsured as Canada’s cyber landscape shifts

Canada’s cyber insurance market is stabilising, with stronger underwriting, steadier loss trends, and more product choice, the Insurance Bureau of Canada says. But the threat landscape is accelerating as attackers weaponise AI, leaving many small and medium-sized enterprises exposed and underinsured.

Rapid market growth brought painful losses during the ransomware surge: from 2019 to 2023, combined loss ratios averaged about 155%, forcing tighter pricing and coverage. Insurers have recalibrated, yet rising AI-enabled phishing and deepfake impersonations are lifting complexity and potential severity.

Policy is catching up unevenly. Bill C-8 in Canada would revive critical-infrastructure cybersecurity standards, stronger oversight, and baseline rules for risk management and incident reporting. Public–private programmes signal progress but need sustained execution.

SMEs remain the pressure point. Low uptake means minor breaches can cost tens or hundreds of thousands, while severe incidents can be fatal. Underinsurance shifts shock to the wider economy, challenging insurers to balance affordability with long-term viability.

The Bureau urges practical resilience: clearer governance, employee training, incident playbooks, and fit-for-purpose cover. Education campaigns and free guidance aim to demystify coverage, boost readiness, and help SMEs recover faster when attacks hit, supporting a more durable digital economy.

AWS glitch triggers widespread outages across major apps

A major internet outage hit some of the world’s biggest apps and sites from about 9 a.m. CET Monday, with issues traced to Amazon Web Services. Tracking sites reported widespread failures across the US and beyond, disrupting consumer and enterprise services.

AWS cited ‘significant error rates’ in DynamoDB requests in the US-EAST-1 region, impacting additional services in Northern Virginia. Engineers are mitigating while investigating root cause, and some customers couldn’t create or update Support Cases.

Outages clustered around Virginia’s dense data-centre corridor but rippled globally. Impacted brands included Amazon, Google, Snapchat, Roblox, Fortnite, Canva, Coinbase, Slack, Signal, Vodafone and the UK tax authority HMRC.

Coinbase told users ‘all funds are safe’ as platforms struggled to authenticate, fetch data and serve content tied to affected back-ends. Third-party monitors noted elevated failure rates across APIs and app logins.

The incident underscores heavy reliance on hyperscale infrastructure and the blast radius when core data services falter. Full restoration and a formal post-mortem are pending from AWS.

Microsoft warns of a surge in ransomware and extortion incidents

Financially motivated cybercrime now accounts for the majority of global digital threats, according to Microsoft’s latest Digital Defense Report.

The company’s analysts found that over half of all cyber incidents with known motives in the past year were driven by extortion or ransomware, while espionage represented only a small fraction.

Microsoft warns that automation and accessible off-the-shelf tools have allowed criminals with limited technical skills to launch widespread attacks, making cybercrime a constant global threat.

The report reveals that attackers increasingly target critical services such as hospitals and local governments, where weak security and urgent operational demands make them easy victims.

Cyberattacks on these sectors have already led to real-world harm, from disrupted emergency care to halted transport systems. Microsoft highlights that collaboration between governments and private industry is essential to protect vulnerable sectors and maintain vital services.

While profit-seeking criminals dominate by volume, nation-state actors are also expanding their reach. State-sponsored operations are growing more sophisticated and unpredictable, with espionage often intertwined with financial motives.

Some state actors even exploit the same cybercriminal networks, complicating attribution and increasing risks for global organisations.

Microsoft notes that AI is being used by both attackers and defenders. Criminals are employing AI to refine phishing campaigns, generate synthetic media and develop adaptive malware, while defenders rely on AI to detect threats faster and close security gaps.

The report urges leaders to prioritise cybersecurity as a strategic responsibility, adopt phishing-resistant multifactor authentication, and build strong defences across industries.

Security, Microsoft concludes, must now be treated as a shared societal duty rather than an isolated technical task.

Capita hit with £14 million fine after major data breach

The UK outsourcing firm Capita has been fined £14 million after a cyber-attack exposed the personal data of 6.6 million people. Sensitive information, including financial details, home addresses, passport images, and criminal records, was compromised.

Initially, the fine was £45 million, but it was reduced after Capita improved its cybersecurity, supported affected individuals, and engaged with regulators.

A breach that affected 325 of the 600 pension schemes Capita manages, highlighting risks for organisations handling large-scale sensitive data.

The Information Commissioner’s Office (ICO) criticised Capita for failing to secure personal information, emphasising that proper security measures could have prevented the incident.

Experts note that holding companies financially accountable reinforces the importance of data protection and sends a message to the market.

Capita’s CEO said the company has strengthened its cyber defences and remains vigilant to prevent future breaches.

The UK government has advised companies like Capita to prepare contingency plans following a rise in nationally significant cyberattacks, a trend also seen at Co-op, M&S, Harrods, and Jaguar Land Rover earlier in the year.

Microsoft finds 71% of UK workers use unapproved AI tools on the job

A new Microsoft survey has revealed that nearly three in four employees in the UK use AI tools at work without company approval.

A practice, referred to as ‘shadow AI’, that involves workers relying on unapproved systems such as ChatGPT to complete routine tasks. Microsoft warned that unauthorised AI use could expose businesses to data leaks, non-compliance risks, and cyber attacks.

The survey, carried out by Censuswide, questioned over 2,000 employees across different sectors. Seventy-one per cent admitted to using AI tools outside official policies, often because they were already familiar with them in their personal lives.

Many reported using such tools to respond to emails, prepare presentations, and perform financial or administrative tasks, saving almost eight hours of work each week.

Microsoft said only enterprise-grade AI systems can provide the privacy and security organisations require. Darren Hardman, Microsoft’s UK and Ireland chief executive, urged companies to ensure workplace AI tools are designed for professional use rather than consumer convenience.

He emphasised that secure integration can allow firms to benefit from AI’s productivity gains while protecting sensitive data.

The study estimated that AI technology saves 12.1 billion working hours annually across the UK, equivalent to about £208 billion in employee time. Workers reported using the time gained through AI to improve work-life balance, learn new skills, and focus on higher-value projects.

Teen content on Instagram now guided by PG-13 standards

Instagram is aligning its Teen Accounts with PG-13 movie standards, aiming to ensure that users under 18 only see age-appropriate material. Teens will automatically be placed in a 13+ setting and will need parental permission to change it.

Parents who want tighter supervision can activate a new ‘Limited Content’ mode that filters out even more material and restricts comments and AI interactions.

The company reviewed its policies to match familiar parental guidelines, further limiting exposure to content with strong language, risky stunts, or references to substances. Teens will also be blocked from following accounts that share inappropriate content or contain suggestive names and bios.

Searches for sensitive terms such as ‘gore’ or ‘alcohol’ will no longer return results, and the same restrictions will extend to Explore, Reels, and AI chat experiences.

Instagram worked with thousands of parents worldwide to shape these policies, collecting more than three million content ratings to refine its protections. Surveys show strong parental support, with most saying the PG-13 system makes it easier to understand what their teens are likely to see online.

The updates begin rolling out in the US, UK, Australia, and Canada and will expand globally by the end of the year.
