Nvidia holds back on optical technology for GPUs

Nvidia’s CEO, Jensen Huang, has s tated that a promising new chip technology, co-packaged optics, is not yet reliable enough for use in the company’s flagship GPUs.

The technology, which uses laser beams to transfer data via fiber optic cables instead of traditional copper, is more energy-efficient and faster.

However, Huang emphasized that copper connections remain ‘orders of magnitude’ more reliable than today’s optical alternatives, making them the preferred choice for now.

Speaking at Nvidia’s annual developer conference in San Jose, Huang announced that the company will use co-packaged optics in two upcoming networking chips designed for server switches, increasing their energy efficiency by three and a half times.

These switch chips will be released later this year and into 2026, marking a gradual technological step forward. However, Huang clarified that Nvidia currently has no plans to implement optical connections between GPUs, as reliability remains a key priority for its AI-focused customers like OpenAI and Oracle.

Silicon Valley startups such as Ayar Labs, Lightmatter, and Celestial AI have invested heavily in co-packaged optics, seeing it as essential for building more powerful AI systems. Nvidia itself has backed some of these ventures, despite Huang’s cautious approach.

While optical connections could eventually help AI models process complex tasks more efficiently, Nvidia is prioritizing proven technology for its near-term roadmap, ensuring stability in an industry preparing to invest hundreds of billions in AI infrastructure.

Google acquires Wiz in $32 billion deal

Google has finalized a $32 billion acquisition of Israeli cybersecurity firm Wiz, sealing the deal just weeks after Donald Trump’s inauguration.

The agreement, a significant increase from Google’s initial $23 billion offer, was aided by the expectation of a friendlier antitrust review under the new administration, sources familiar with the negotiations said.

Wiz had considered an IPO before returning to the negotiating table, with new Chief Financial Officer Fazal Merchant playing a key role in shaping the deal alongside CEO Assaf Rappaport.

Google’s cloud chief, Thomas Kurian, was also instrumental in the agreement, which includes an unusually high $3.2 billion breakup fee should regulatory issues derail the transaction.

With Wiz boasting 70% annual revenue growth and over $700 million in annualized revenue, Google viewed the premium price as justified.

However, concerns remain over potential antitrust scrutiny, particularly given Google’s ongoing legal battles with the US Department of Justice over its dominance in search and ad technology.

Meta cracks down on misinformation in Australia

Meta Platforms has announced new measures to combat misinformation and deepfakes in Australia ahead of the country’s upcoming national election.

The company’s independent fact-checking program, supported by Agence France-Presse and the Australian Associated Press, will detect and limit misleading content, while also removing any material that could incite violence or interfere with voting.

Deepfakes, AI-generated media designed to appear real, will also face stricter scrutiny. Meta stated that any content violating its policies would be removed or labelled as ‘altered’ to reduce its visibility.

Users sharing AI-generated content will be encouraged to disclose its origin, aiming to improve transparency.

Meta’s Australian policy follows similar strategies used in elections across India, the UK and the US.

The company is also navigating regulatory challenges in the country, including a proposed levy on big tech firms profiting from local news content and new requirements to enforce a ban on users under 16 by the end of the year.

Samsung faces tough shareholder meeting over AI struggles

Samsung Electronics faces a challenging annual general meeting as shareholders express frustration over its failure to capitalise on the AI boom.

Despite being South Korea’s most valuable company, Samsung’s stock tumbled nearly a third last year, making it one of the worst-performing tech firms.

Executives, including Co-CEO Han Jong-hee, will address concerns over lagging innovation, competition in semiconductor technology, and strategies to counter US tariffs.

Internal discussions at Samsung have revealed concerns about losing its technological edge, particularly in high bandwidth memory (HBM) chips, where it trails rival SK Hynix.

Chairman Jay Y. Lee reportedly criticised the company for focusing on maintaining the status quo rather than driving major innovation.

A stagnation like this has contributed to Samsung losing market share to competitors like TSMC in chip manufacturing and Apple in smartphones.

Adding to its challenges, Samsung has warned of sluggish AI chip sales due to US export restrictions to China, its biggest market. This puts the company at greater risk from potential US tariffs on Chinese trade.

In an attempt to regain investor confidence, Samsung launched a $7.2 billion share buyback plan in November, which has helped its stock recover slightly. However, shareholders remain sceptical about its future growth strategy.

Spanish police dismantle Bitcoin-themed crypto scam

Spanish police have successfully dismantled a Bitcoin-themed pyramid scam, uncovering a fraudulent network that swindled around $32.6 million from unsuspecting victims.

According to the National Police Corps (CNP), eight individuals were arrested, including the mastermind, a computer programmer detained in Malaga. The scam targeted over 3,600 people, mostly in Spain, but extended its reach to 36 countries.

The group operated a seemingly legitimate platform offering various Bitcoin investment plans. Promoted through websites and social media, victims were promised significant returns, with some reportedly offered dividends of 40% in just a month.

However, once funds were invested, obstacles were fabricated to delay or prevent withdrawals.

The police first uncovered the operation in 2022, following a report from a victim in Murcia. Their investigation revealed the scam’s pyramid structure, where older investors were paid with funds from newer ones.

Some victims were even tricked into handing over control of their devices for crypto transfers.

In total, the fraudsters amassed approximately 400 Bitcoin and created a worthless token for investors. Authorities have since frozen 73 bank accounts, seized cars, and impounded various assets as part of the investigation.

Microsoft warns of new malware targeting cryptocurrency wallets

Microsoft has issued a warning about StilachiRAT, a newly discovered malware that steals cryptocurrency wallet data and sensitive browser information.

The trojan is designed to evade detection while extracting credentials from over 20 different wallets, including MetaMask, Trust Wallet, and Coinbase.

The malware actively scans for cryptocurrency wallet extensions in Google Chrome and monitors clipboard actions for copied keys and passwords.

Attackers can use the stolen data to drain victims’ funds. StilachiRAT also enables remote command execution, allowing cybercriminals to manipulate system settings and maintain control over infected devices.

Beyond stealing data, the malware gathers detailed information about the compromised system, including OS details and hardware identifiers.

It even monitors Remote Desktop Protocol sessions, enabling attackers to impersonate users and spread further across networks.

Microsoft has not yet linked StilachiRAT to a specific threat actor but emphasises the need for caution. Users are advised to download software only from official sources, enable Microsoft Defender real time protection, and use SmartScreen to block malicious websites.

US launches national security unit to combat cyberattacks on telecom sector

The Federal Communications Commission (FCC) has launched a national security unit in response to recent cyber incidents affecting US telecommunications firms.

These incidents, attributed to a group known as Salt Typhoon, involved unauthorised access to sensitive data and communications.

The newly formed unit will be led by Adam Chan, FCC’s national security counsel, and will include representatives from eight different bureaus and offices within the agency. The council’s objectives are to:

Reduce reliance on foreign entities in the US telecom and technology supply chains.
Address vulnerabilities related to cyber threats, espionage, and surveillance.
Support U.S. leadership in critical technologies, including 5G, satellites, quantum computing, IoT, and robotics.

Cybersecurity experts have emphasised the importance of securing digital infrastructure against advanced threats. The telecommunications sector, despite its established cybersecurity measures, continues to face persistent and evolving risks.

Recent reports indicate that Salt Typhoon has continued targeting US telecom networks, with activity observed as recently as February.

The FCC has taken several steps in recent months to enhance industry security, and the formation of this council represents a further effort to strengthen resilience.

ICC Office of the Prosecutor invites public input on draft policy for cyber-enabled crimes

The Office of the Prosecutor of the International Criminal Court invites public comments on its draft policy addressing cyber-enabled crimes under the Rome Statute.

The Office encourages participation from all relevant stakeholders, including States Parties, civil society organisations, private sector entities, and experts in the field.

Contributions will support the development of a final policy paper that will guide the Office’s approach to cyber-related conduct within its jurisdiction, including its investigative and prosecutorial activities.

The policy paper builds on the crimes outlined in the Rome Statute, assessed within the broader framework of international law.

It aims to enhance transparency regarding the Office’s work in this area and contribute to discussions on legal standards, best practices, and frameworks for cooperation, including those relevant to national authorities.

The draft policy clarifies that the Court does not have jurisdiction over common cybercrimes, such as fraud or unauthorised access to computer systems, which are typically addressed under national laws.

While some countries have international obligations to prosecute these crimes under specific treaties, they do not fall within the mandate of the Court. However, national efforts to combat such crimes may sometimes overlap with the Court’s work where they intersect with crimes under its jurisdiction.

To date, cyber-related issues have only been considered at the periphery of the Court’s work, and their legal and practical implications have yet to be fully explored.

Investigating and prosecuting cyber-enabled crimes presents new and complex challenges. This policy sets out the Office’s current position on these issues while recognising that certain matters may only be fully addressed as the Court’s practice in this area develops.

As with any crime under the Court’s jurisdiction, cyber-enabled crimes will be assessed based on their gravity—including their scale, nature, manner of commission, and impact.

The Court focuses on crimes of the most serious international concern, typically those causing widespread harm to large populations.

An exception applies to offences against the administration of justice, which are not subject to a gravity threshold but are considered serious due to their impact on the Court’s ability to function.

Pavel Durov granted temporary leave from France in legal case

French authorities have granted Pavel Durov, the Russian-born founder and CEO of Telegram, temporary permission to leave France.

Durov was placed under formal inve s tigation last August over alleged criminal activities on the messaging platform and had been barred from leaving the country. He departed for Dubai on Saturday after an investigating judge approved his temporary absence.

The legal probe has heightened tensions between France and Russia, particularly against the backdrop of the war in Ukraine.

Prosecutors suspect Durov of complicity in allowing illegal activities such as drug trafficking and money laundering on Telegram. As part of his legal obligations, he was required to post bail of 5 million euros ($5.4 million).

Being under formal investigation in France does not imply guilt but indicates that judges believe there is sufficient evidence to continue the case. The Paris prosecutor’s office has not commented on the latest developments.

EU delays ETIAS launch until late 2026

The European Union has announced that the ETIAS (European Travel Information and Authorisation System) will require visa-free travellers from non-EU countries, including the UK, to obtain authorisation before short stays in the Schengen Area.

Initially planned for 2026, the system has been delayed and is now set to launch in late 2026, with full implementation not expected until 2027. The ETIAS aims to improve border security and will apply to travellers from 60 non-EU countries who don’t need a visa.

To apply for the ETIAS, travellers will need to complete an online application, provide personal details, answer security questions, and pay a €7 fee.

However, this authorisation will be linked to the traveller’s passport and remain valid for three years, or until the passport expires. Also, children under 18 and adults over 70 will be exempt from the fee, though they still need to apply for authorisation.

The ETIAS will not become mandatory until six months after the EU’s Entry/Exit System (EES) is fully operational. The EES, which is set to launch in phases starting in October 2025, will be a registration system for non-EU travellers, including those from the UK and US.

However, due to delays in the installation of necessary technology at Schengen borders, the launch of the ETIAS has been pushed back to late 2026.
