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.

Bitcoin wallet vulnerability exposes thousands of private keys

A flaw in the widely used Libbitcoin Explorer (bx) 3.x series has exposed over 120,000 Bitcoin private keys, according to crypto wallet provider OneKey. The flaw arose from a weak random number generator that used system time, making wallet keys predictable.

Attackers aware of wallet creation times could reconstruct private keys and access funds.

Several wallets were affected, including versions of Trust Wallet Extension and Trust Wallet Core prior to patched releases. Researchers said the Mersenne Twister-32’s limited seed space let hackers automate attacks and recreate private keys, possibly causing past fund losses like the ‘Milk Sad’ cases.

OneKey confirmed its own wallets remain secure, using cryptographically strong random number generation and hardware Secure Elements certified to global security standards.

OneKey also examined its software wallets, ensuring that desktop, browser, Android, and iOS versions rely on secure system-level entropy sources. The firm urged long-term crypto holders to use hardware wallets and avoid importing software-generated mnemonics to reduce risk.

The company emphasised that wallet security depends on the integrity of the device and operating environment.

UK government urges awareness as £106m lost to romance fraud in one year

Romance fraud has surged across the United Kingdom, with new figures showing that victims lost a combined £106 million in the past financial year. Action Fraud, the UK’s national reporting centre for cybercrime, described the crime as one that causes severe financial, emotional, and social damage.

Among the victims is London banker Varun Yadav, who lost £40,000 to a scammer posing as a romantic partner on a dating app. After months of chatting online, the fraudster persuaded him to invest in a cryptocurrency platform.

When his funds became inaccessible, Yadav realised he had been deceived. ‘You see all the signs, but you are so emotionally attached,’ he said. ‘You are willing to lose the money, but not the connection.’

The Financial Conduct Authority (FCA) said banks should play a stronger role in disrupting romance scams, calling for improved detection systems and better staff training to identify vulnerable customers. It urged firms to adopt what it called ‘compassionate aftercare’ for those affected.

Romance fraud typically involves criminals creating fake online profiles to build emotional connections before manipulating victims into transferring money.

The National Cyber Security Centre (NCSC) and UK police recommend maintaining privacy on social media, avoiding financial transfers to online contacts, and speaking openly with friends or family before sending money.

The Metropolitan Police recently launched an awareness campaign featuring victim testimonies and guidance on spotting red flags. The initiative also promotes collaboration with dating apps, banks, and social platforms to identify fraud networks.

Detective Superintendent Kerry Wood, head of economic crime for the Met Police, said that romance scams remain ‘one of the most devastating’ forms of fraud. ‘It’s an abuse of trust which undermines people’s confidence and sense of self-worth. Awareness is the most powerful defence against fraud,’ she said.

Although Yadav never recovered his savings, he said sharing his story helped him rebuild his life. He urged others facing similar scams to speak up: ‘Do not isolate yourself. There is hope.’

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.

UK and US freeze assets of Southeast Asian online scam network

The UK and US governments have jointly sanctioned a transnational network operating illegal scam centres across Southeast Asia. These centres use sophisticated methods, including fake romantic relationships, to defraud victims worldwide.

Many of the individuals forced to conduct these scams are trafficked foreign nationals, coerced under threat of torture. Authorities have frozen a £12 million North London mansion, along with a £100 million City office and several London flats.

Network leader Chen Zhi and his associates used corporate proxies and overseas companies to launder proceeds from their scams through London’s property market.

The sanctioned entities include the Prince Group, Jin Bei Group, Golden Fortune Resorts World Ltd., and Byex Exchange. Scam operations trap foreign nationals with fake job adverts, forcing them to commit online fraud, often through fake cryptocurrency schemes.

Proceeds are then laundered through a complex system of front businesses and gambling platforms.

Foreign Secretary Yvette Cooper and Fraud Minister Lord Hanson said the action protects human rights, UK citizens, and blocks criminals from storing illicit funds. Coordination with the US ensures these sanctions disrupt the network’s international operations and financial access.

US seizes $15 billion crypto from Cambodia fraud ring

US federal prosecutors have seized $15 billion in cryptocurrency tied to a large-scale ‘pig butchering’ investment scam linked to forced labour compounds in Cambodia. Officials said it marks the biggest crypto forfeiture in Justice Department history.

Authorities charged Chinese-born businessman Chen Zhi, founder of the Prince Group, with money laundering and wire fraud. Chen allegedly used the conglomerate as cover for criminal operations that laundered billions through fake crypto investments. He remains at large.

Investigators say Chen and his associates operated at least ten forced labour sites in Cambodia where victims, many coerced workers, managed thousands of fake social media accounts to lure targets into fraudulent investment schemes.

The US Treasury also imposed sanctions on dozens of Prince Group affiliates, calling them transnational criminal organisations. FBI officials said the scam is part of a wider wave of crypto fraud across Southeast Asia, urging anyone targeted by online investment offers to contact authorities immediately.
