Tech news November 2026: Binance, Nvidia, Revolut and more
The past few weeks have brought news that moved markets and also has lessons for any business: the largest cryptocurrency theft in history, an internal investigation at the world’s most valuable chipmaker, a record valuation in digital banking and urgent security patches. Here is a summary based on official sources and leading media.
Binance: the largest crypto theft in history
In late October 2026, Binance, the world’s largest cryptocurrency exchange, suffered a theft of around $6.3 billion. The FBI has attributed it to hackers from North Korea, specifically the group known as TraderTraitor, also blamed for the $1.5 billion Bybit theft. North Korea has denied involvement.
Binance suspended withdrawals and began reopening them in phases on 1 November, starting with the Bitcoin network. The FBI has published hundreds of addresses linked to the theft and asked exchanges to block them. The market felt it: bitcoin fell below $80,000 in the following days.
We explain it in more detail, with lessons for any business, in what happened at Binance and what your company can learn.
Nvidia: the board investigates its CEO
On 8 November, Nvidia’s board announced an independent investigation after press reports that CEO Jensen Huang may have been the target of a foreign intelligence operation through a personal relationship. Huang acknowledged the relationship in an email to staff, apologised and said he will cooperate fully. The stock fell more than 4 % on 9 November. The investigation is at an early stage and there are no findings. We analyse it in detail in Nvidia investigates Jensen Huang.
Revolut reaches a $115 billion valuation
On 4 November, Revolut confirmed it had completed a share sale at a valuation of $115 billion. It was a secondary sale: employees and investors sold existing shares, so no new money went into the company. The previous valuation, from late 2025, was $75 billion.
Revolut says it has more than 80 million retail customers and keeps adding banking licences: in the same days it announced its New Zealand licence and received a conditional licence from the Bank of Israel. According to the specialist press, an IPO would not come before 2028.
The takeaway for businesses: digital banking and mobile payments are now the norm for many customers. Making sure your checkout, online shop and invoicing accept and reconcile these payments without manual work matters more and more.
Cybersecurity: urgent patches for NAS and VPN
- Synology warned on 29 October of ransomware attacks (C3RB3R) against NAS devices running old versions of its DSM system.
- The US Cybersecurity and Infrastructure Security Agency (CISA) added a flaw in the SonicWall VPN to its catalogue of exploited vulnerabilities on 6 November. With SAML login enabled, it can allow attackers to bypass two-step verification.
What to do, step by step: ransomware against Synology NAS and the SonicWall VPN flaw.
AI in Spain: one in three companies already use it
Spain’s statistics office (INE) published its business technology survey on 22 October: 33.6 % of companies with 10 or more employees used artificial intelligence in the first quarter of 2026, up from 21.1 % a year earlier. We analyse it in this article (in Spanish).
Our takeaways
- The most serious attacks combine technology and social engineering: training your team matters as much as antivirus software.
- Patches must be applied in days, not months, especially on internet-facing devices such as NAS, VPNs and web servers.
- AI is no longer a bet on the future: companies that apply it with good judgement gain an edge. If you do not know where to start, our AI assessment is the first step.
