Thailand stock exchange halts trading after earthquake

The Stock Exchange of Thailand (SET) suspended all trading activities for the afternoon session on Friday after a powerful earthquake hit neighbouring Myanmar, sending tremors across Bangkok.

The exchange announced the immediate closure on its website, citing the impact of the seismic event.

The suspension affected all markets, including the SET, the Market for Alternative Investment (MAI), and the Thailand Futures Exchange (TFEX). The decision was made as a precautionary measure following the quake, which caused concern among investors and businesses in the region.

Before the halt, the benchmark SET index was trading 1.05% lower at 1,175.45 points, marking an over one-week low.

The market had already been under pressure earlier in the session due to concerns over new US auto tariffs, adding to the volatility triggered by the earthquake.

NHS contractor fined after ransomware attack

The tech firm Advanced, which provides services to the NHS, has been fined over £3 million by the UK data watchdog following a major ransomware attack in 2022.

The breach disrupted NHS systems and exposed personal data from tens of thousands across the country.

Originally facing a £6 million penalty, Advanced saw the fine halved after settling with the Information Commissioner’s Office.

Regulators said the firm failed to implement multi-factor authentication, allowing hackers to access systems using stolen login details.

The LockBit attack caused widespread outages, including access to UK patient data. While Advanced acknowledged the resolution, it declined to offer further comment or name a spokesperson when contacted.

WhatsApp wins support in EU fine appeal

WhatsApp has gained support from an adviser to the European Court of Justice in its fight against a higher fine imposed by the EU privacy watchdog.

The Irish Data Protection Authority fined WhatsApp 225 million euros ($242.2 million) in 2021 for privacy breaches.

The fine was increased after the European Data Protection Board (EDPB) intervened.

A lower tribunal had rejected WhatsApp’s challenge, saying the company lacked legal standing. However, WhatsApp appealed to the Court of Justice of the European Union (CJEU).

Advocate General Tamara Capeta disagreed with the tribunal, recommending that the case be referred back to the General Court for further review.

The CJEU usually follows the adviser’s recommendations, and a final ruling is expected soon. This case could have significant implications for the fine imposed on WhatsApp.

Trump weighs tariff cuts to secure TikTok deal

US President Donald Trump has indicated he is willing to reduce tariffs on China as part of a deal with ByteDance, TikTok’s Chinese parent company, to sell the popular short-video app.

ByteDance faces an April 5 deadline to divest TikTok’s US operations or risk a nationwide ban over national security concerns.

The law mandating the sale stems from fears in Washington that Beijing could exploit the app for influence operations and data collection on American users.

Trump suggested he may extend the deadline if negotiations require more time and acknowledged China’s role in the deal’s approval. Speaking to reporters, he hinted that tariff reductions could be used as leverage to finalise an agreement.

China’s commerce ministry responded by reaffirming its stance on trade discussions, stating that engagement with Washington should be based on mutual respect and benefit.

The White House has taken an active role in brokering a potential sale, with discussions centring on major non-Chinese investors increasing their stakes to acquire TikTok’s US operations. Vice President JD Vance has expressed confidence that a framework for the deal could be reached by the April deadline.

Free speech advocates, meanwhile, continue to challenge the law, arguing that banning TikTok could violate the First Amendment rights of American users.

Mobile coverage from space may soon be reality

Satellite-based mobile coverage could arrive in the UK by the end of 2025, with Ofcom launching a consultation on licensing direct-to-smartphone services.

The move would allow users to stay connected in areas without mast coverage using an ordinary mobile phone.

The proposal favours mobile networks teaming up with satellite operators to share frequencies in unserved regions, offering limited services like text messaging at first, with voice and data to follow.

Ofcom plans strict interference controls, and Vodafone is among those preparing to roll out such technology.

If approved, the service would be available across the UK mainland and surrounding seas, but not yet in places like the Channel Islands.

The public has until May to respond, as Ofcom seeks to modernise mobile access and help close the digital divide.

US tightens controls on China’s tech sector amid security fears

The United States has added six subsidiaries of China’s leading cloud computing firm, Inspur Group, along with dozens of other Chinese entities, to its export restriction list.

Washington accuses the companies of aiding China’s military by developing supercomputers and advanced AI technologies. The move is part of a broader strategy to curb China’s progress in high-performance computing, quantum technology, and hypersonic weapons development.

Other companies from Taiwan, Iran, Pakistan, South Africa, and the UAE were also included in the latest restrictions. China has strongly condemned the US decision, calling it an attempt to ‘weaponise trade and technology.’

The Chinese foreign ministry has vowed to take necessary measures to protect its firms, while the Beijing Academy of Artificial Intelligence, which was also targeted, called for the restrictions to be withdrawn.

Companies added to the US Entity List require special licences to access American technology, which are unlikely to be granted. The restrictions could impact major Chinese tech firms linked to AI and computing, such as Huawei and Sugon.

The United States Commerce Department argues that these measures are necessary to prevent China and other countries from using American technology for military applications. Officials insist they will not allow adversaries to strengthen their military capabilities with US-made components.

The latest crackdown follows a 2023 decision to blacklist Inspur Group, which led to scrutiny of its business ties with major US chipmakers such as Nvidia and AMD. Washington also aims to block Iran’s procurement of drone and missile technology as part of its broader national security efforts.

Lawmakers demand probe into Trump team’s Signal breach

​Top officials from the Trump administration inadvertently included a journalist in an encrypted Signal chat while discussing military plans, leading to concerns over a potential security breach.

The incident has prompted Democratic lawmakers to call for a congressional investigation into the mishandling of classified information. Although US law criminalises the misuse of such data, it remains uncertain if legal provisions were violated in this case. ​

Signal is a widely trusted encrypted messaging app known for strong privacy protections. The service, instead of storing user messages on its servers, keeps data solely on users’ devices, with an option to automatically delete conversations.

Unlike other platforms, Signal does not track user data, use ads, or affiliate with marketers. Its encryption is independent of any government, and cybersecurity experts consider it highly secure. However, if a device itself is compromised, messages within the app can still be accessed by hackers. ​

The app was co-founded by Moxie Marlinspike in 2012 and later supported by WhatsApp co-founder Brian Acton, who left WhatsApp over concerns regarding data privacy.

Signal is run by the non-profit Signal Foundation and has grown in popularity, especially among privacy advocates, journalists, and government agencies.

The European Commission and the US Senate have also endorsed its use. However, experts question whether it is appropriate for discussions involving national security matters, given the risk of mobile device vulnerabilities. ​

Signal saw a significant surge in users in 2021 after WhatsApp introduced a controversial privacy policy update.

Despite its reputation for security, the recent incident with Trump administration officials highlights concerns about the suitability of even the most encrypted platforms for handling sensitive government information.

AI powers Microsoft’s latest security upgrade

Microsoft has launched a new set of AI agents as part of its Security Copilot platform, aiming to automate key cybersecurity tasks like phishing detection, data protection, and identity management. The release includes six in-house agents and five developed with partners.

Among the tools is a phishing triage agent that can autonomously process routine alerts, freeing analysts to focus on advanced incidents.

Microsoft said its new AI-driven approach goes beyond traditional security platforms, using generative AI to prioritise threats, correlate data, and even recommend or execute responses.

The rollout also brings new capabilities to Microsoft Defender, Entra, and Purview, enhancing organisations’ ability to manage and secure AI systems.

While analysts welcome the move as a step forward in proactive cybersecurity, some warn that full reliance on one platform carries strategic risks like vendor lock-in and reduced flexibility.

Experts suggest a balanced approach that combines Microsoft’s core capabilities with specialised solutions for areas such as threat intelligence and cloud protection, helping organisations stay agile in a fast-evolving threat landscape.

Samsung loses Qualcomm chip deal

Qualcomm is reportedly passing over Samsung for its upcoming Snapdragon 8s Gen 4 chip, choosing instead to stick with Taiwan’s TSMC for manufacturing.

Despite Samsung’s proven 4nm process and efforts to regain market confidence, Qualcomm appears hesitant to return after earlier issues with Samsung’s 3nm technology.

The new chipset is said to feature a mix of high-performance Cortex-X4 and A720 cores, notably lacking Qualcomm’s custom Oryon designs. However, this time around the company is being left out despite recent improvements in yield and packaging capabilities.

Samsung has focused on enhancing its legacy chip processes, recently beginning mass production of its fourth-generation 4nm chips.

The persistent trust issues seem to outweigh the technical strides, with Qualcomm opting to play it safe and rely solely on Taiwan’s TSMC’s consistency for this release.

Cerebras IPO faces further delays

Cerebras Systems’ plans for a public listing remain in limbo as a national security review by the US government continues to delay the AI chipmaker’s IPO.

The review, conducted by the Committee on Foreign Investment in the United States (CFIUS), is assessing a $335 million investment from Abu Dhabi-based AI firm G42, which has faced scrutiny over its past ties to China.

While executives had hoped for a smoother process under President Trump, delays in filling key political positions have further complicated approval.

Without clarity on G42’s stake, investors remain cautious, making it difficult for Cerebras to move forward. The situation reflects a broader reality for Wall Street, as expectations of a more deal-friendly environment under Trump have yet to materialise.

Analysts suggest that instead of rolling back Biden-era policies, the administration is likely to maintain or even expand scrutiny on foreign investments, particularly those linked to China.

Instead of a setback, Cerebras remains optimistic that the deal will be approved, with plans to proceed with its IPO once clearance is granted.

The company, valued at $8 billion last year, has seen its worth nearly double since then. Meanwhile, G42 has distanced itself from Huawei and secured a national security agreement with the US in an effort to gain regulatory approval.
