Microsoft announced that most services for Outlook and Teams were restored late Monday after a widespread outage disrupted users throughout the day. While a small number of users continue to face issues with Outlook on the web, the company promised full restoration by Tuesday.
The disruption peaked with over 5,000 complaints logged on Downdetector, though Microsoft implemented fixes that restored functionality to 98% of affected environments by midday. Progress slowed in the afternoon, but by evening, reports of issues had significantly declined.
This outage, which impacted countless office workers ahead of the Thanksgiving holiday, is the latest in a year of major tech disruptions globally. Although significant, the scale of this incident was far smaller than the summer outage of CrowdStrike’s systems, which caused billions in losses across industries.
Aleksei Andriunin, the founder of cryptocurrency firm Gotbit, has been indicted in the US for alleged involvement in a conspiracy to manipulate cryptocurrency markets. The Justice Department claims that Andriunin and his firm provided market manipulation services to increase artificial trading volumes for various cryptocurrency companies from 2018 to 2024.
The superseding indictment also names Gotbit’s directors, Fedor Kedrov and Qawi Jalili, who were already charged earlier in October. Prosecutors allege that these actions aimed to distort the cryptocurrency markets, with several companies, including some in the United States, reportedly benefitting from these tactics.
If convicted, Andriunin faces significant penalties, with wire fraud charges carrying a potential 20-year prison sentence. He could also face an additional five years for conspiracy charges. The allegations form part of a larger crackdown on crypto market manipulation, which has already led to several arrests and asset seizures worth $25 million.
Recent moves by federal prosecutors highlight a more aggressive stance on crypto-related fraud. They have targeted multiple firms, including Gotbit, and several leaders have already agreed to plead guilty. The crackdown aims to strengthen transparency and curb malpractice in the cryptocurrency market.
China’s Ministry of State Security announced the discovery of foreign spying devices in its waters, including underwater ‘lighthouses’ that could potentially guide foreign submarines. The ministry revealed on its official WeChat account that it had retrieved several types of devices hidden on the ocean floor, gathering real-time data from within China’s claimed territorial waters.
This revelation comes amid rising tensions in the South China Sea, where China and the Philippines dispute territory, increasing the risk of a broader confrontation potentially involving the US. China’s recent military drills around Taiwan have also heightened concerns, as the US and Taiwan have condemned Beijing’s actions.
China claims nearly all of the South China Sea, overlapping areas claimed by other Southeast Asian nations, and has maintained it will not renounce using force over Taiwan. A new phase in the submarine arms race between China and the US and its allies is underway, with Beijing projected to field nuclear-armed submarines by the decade’s end. The ministry affirmed its commitment to defending China’s maritime sovereignty and addressing threats of foreign espionage in its waters.
A Londoner who had his phone stolen while walking near the Science Museum believes Google’s new AI security update would have made a big difference. Tyler, whose phone was snatched by a thief on a bike, struggled to lock it remotely as he couldn’t remember his password. The update, which uses AI and sensors to detect when a phone is stolen, would automatically lock the screen to prevent thieves from accessing data.
Google’s new feature allows users to remotely lock a stolen device using just their phone number, a measure welcomed by Tyler as he believes it would have helped him secure his device in moments of panic. The initiative is part of a broader effort to combat phone theft, with mobile phones now accounting for 69% of all thefts in London. Last year, over 11,800 robberies involved phone thefts.
Sadiq Khan, the Mayor of London, also supports the update, having previously lobbied phone companies to make their devices less attractive to criminals. Tech experts say the update’s AI-driven security, combined with the Offline Device Lock feature, will make it harder for thieves to access stolen phones.
Tyler hopes the new technology will deter criminals from stealing phones altogether, as the devices would become worthless once locked. Without resale value, he believes phone thefts will be a waste of time for criminals.
Chinese researchers from Shanghai University have claimed a significant breakthrough in quantum computing, asserting that they breached encryption algorithms commonly used in banking and cryptocurrency. Led by Wang Chao, the team employed a quantum computer from Canada’s D-Wave Systems to exploit vulnerabilities in the Present, Gift-64, and Rectangle algorithms, which form the backbone of the Substitution-Permutation Network (SPN) structure underpinning advanced encryption standards (AES) widely used for securing cryptocurrency wallets.
While AES-256 is regarded as one of the most secure encryption standards, the researchers warn that the advent of quantum computers could pose a serious threat to traditional password protection. Their technique, based on quantum annealing, operates similarly to artificial intelligence algorithms, allowing for more efficient searches by circumventing obstacles that traditional methods struggle to overcome.
Despite these advancements, the researchers noted that practical limitations remain, such as environmental factors and hardware constraints that prevent a full-scale quantum attack at this time. However, they emphasised that future developments could uncover new vulnerabilities in current cryptographic systems.
Ethereum co-founder Vitalik Buterin has proposed a potential solution to mitigate the risk posed by quantum computing, suggesting a hard fork of the Ethereum blockchain to implement new wallet software and enhance security. He indicated that the necessary infrastructure for such a move could be developed promptly, providing a proactive approach to safeguarding user funds.
Criminal networks in Southeast Asia are increasingly exploiting Telegram for large-scale illicit activities, according to a new report from the United Nations. The encrypted messaging app is used to trade hacked data, including credit card details and passwords, across sprawling, poorly-moderated channels. The report also notes that unlicensed cryptocurrency exchanges on the platform provide money laundering services.
Fraud tools, such as deepfake software and data-stealing malware, are widely sold, enabling organised crime syndicates to innovate and expand their operations. One vendor in Chinese reportedly claimed to move millions in stolen cryptocurrency daily. Southeast Asia has become a hub for these activities, where criminal groups target victims worldwide, generating up to $36.5 billion annually.
The controversy surrounding Telegram escalated when its founder, Pavel Durov, was arrested in Paris for allowing criminal activity on the platform. Durov, who is now out on bail, has since announced steps to cooperate with law enforcement by sharing users’ information when requested legally and removing certain features used for illegal purposes.
As the UNODC report warns, the widespread use of Telegram for underground markets places consumers’ data at heightened risk. Criminals are not only exploiting technology like artificial intelligence but are also leveraging the platform’s ease of use to target victims globally.
Russia has ordered Discord to delete nearly 1,000 posts that are deemed illegal. The communication regulator, Roskomnadzor, highlighted that the posts include content related to child pornography, extremism, drug abuse, and LGBT promotion.
Discord, a San Francisco-based platform, and the regulator have yet to respond to queries regarding the order. Previous actions have seen Discord fined 3.5 million roubles for failing to remove illegal material.
Russia’s demands follow a long-standing policy of controlling content on foreign technology platforms. Regular fines are issued for non-compliance, with social media platforms even facing bans in some instances.
President Vladimir Putin continues to emphasise traditional values, particularly with stricter rules on LGBT promotion. Moscow’s broader push aims to restrict content that contradicts the state’s values and regulations.
California has introduced a new law requiring schools to limit or ban the use of smartphones to combat rising concerns about their impact on mental health and education. Governor Gavin Newsom signed the bill following increasing evidence linking excessive phone use with anxiety, depression, and learning difficulties.
California is joining thirteen other states, including Florida, which introduced a similar ban last year. Los Angeles County schools, the state’s largest district, already prohibited phones for its 429,000 students earlier this year. The law, aimed at promoting student focus and social development, reflects a broader national movement to reduce smartphone use among young people.
Surgeon General Vivek Murthy has warned of the growing mental health crisis associated with social media, comparing it to the dangers of smoking. Studies in the US suggest that teenagers spending more than three hours a day on social media are at increased risk of mental illness, with average usage exceeding four hours daily.
School boards across California will be required to implement policies limiting phone use by July 2026, with updates every five years. Newsom stressed the importance of addressing the issue early to improve students’ wellbeing and academic focus.
Ukraine has banned the Telegram messaging app for government officials and critical workers due to concerns about Russian espionage. The National Security and Defence Council implemented these restrictions after Kyrylo Budanov, head of the military intelligence agency, presented evidence indicating that Russian special services could access Telegram messages, including deleted ones.
The ban only affects official devices, allowing government personnel to use personal phones without restriction. Despite its risks, Telegram has played a crucial role in communication and information sharing since the onset of the war in February 2022, with a significant portion of the Ukrainian population relying on the app for updates.
Pavel Durov, the founder of Telegram, has denied claims that the platform shares user data with any country, including Russia. He emphasised that deleted messages are permanently erased and cannot be recovered. However, Ukrainian security officials maintain that the national security implications necessitate this decision.
President Volodymyr Zelenskiy and various officials regularly use Telegram to communicate vital updates. With approximately 75% of people in Ukraine using the app, the restrictions mark a significant shift in the approach to information security amid ongoing conflict.
Microsoft is developing an alternative platform for cybersecurity companies that currently rely on deep access to its operating system’s kernel layer, following a global IT crisis caused by a faulty CrowdStrike update. In response to customer and partner demand, Microsoft announced plans to design a ‘new platform capability’ that would allow security vendors to operate without needing kernel-level access, which is the most critical layer of the OS.
This initiative aims to improve system reliability while maintaining strong security. The shift will require significant changes not only for Microsoft but also for external cybersecurity firms that use kernel access to detect threats. Microsoft explained that newer versions of Windows provide more ways for cybersecurity vendors to offer services outside of the kernel layer. However, some in the security industry believe kernel access is still essential for innovation and advanced threat detection.
Sophos’ Chief Research Officer, Simon Reed, emphasised that kernel access is vital for security products, describing it as fundamental to both Sophos’ offerings and Windows endpoint security in general. ESET echoed this sentiment, supporting changes to the Windows ecosystem as long as they do not weaken security or limit cybersecurity solution options. Both companies argue that restricting kernel access would hinder innovation and the detection of future threats.
The debate over kernel access is unlikely to result in major changes soon, as security companies fear it could give Microsoft’s own security products an unfair advantage. Given Microsoft’s antitrust history, this issue could end up in court, with government officials from the US and Europe closely monitoring developments.
