Breaking AI & Tech News Analyzed

Revolut, the UK banking app, has reported a 57% increase in profits for 2025, but warned that its support for energy-intensive sectors such as crypto and AI could lead to a reputational risk. The fintech company, which can now launch as a fully fledged UK bank after a five-year wait for regulatory approval, offers crypto trading and has applied for a banking licence in the US.The company's annual report highlighted that cryptocurrency mining and AI datacentres demand large amounts of power, with competition for electricity supplies getting steeper since the US-Israel war on Iran sent energy prices soaring over the past month. Revolut's chief executive, Nik Storonsky, hailed another “landmark year” for the company, which has 68.3 million individual customers and 767,000 business customers.Revolut's growth has been rapid, with revenues climbing 46% to £4.5bn and a £1.7bn pre-tax profit for 2025. The company plans to offer a wider array of banking services in the future, such as lending and other products, and has launched mortgage refinancing in Lithuania. Despite the potential risks, Revolut believes its digital-first approach and emphasis on financial inclusion could lead to it being “relatively insulated and even benefit from an orderly energy transition, relative to traditional financial institutions”.

Rapid‑Action Spyware: The Darksword Campaign UnveiledResearchers at Google, iVerify and Lookout traced a fresh wave of iPhone attacks against Ukrainian users to a toolkit they named Darksword. The tool, linked to the threat actor UNC6353, infiltrates devices via compromised Ukrainian websites, siphons passwords, photos, messaging app data and wallet credentials, then vanishes within minutes.Technical Footprint and Quick‑Turnover MetricsInfection vector: malicious scripts on Ukrainian‑hosted sites, active only for visitors inside Ukraine.Data exfiltration window: minutes of dwell time, depending on volume of harvested information.Capabilities: extraction of WhatsApp, Telegram, SMS, browser history, and cryptocurrency wallet keys.Design: modular architecture allowing rapid addition of new functions, mirroring the earlier Coruna toolkit.Geopolitical and Security ImplicationsThe Darksword operation underscores a growing trend of state‑aligned actors deploying highly specialized mobile spyware for short‑term, high‑value “smash‑and‑grab” missions. While the campaign was geographically limited to Ukraine, its sophistication suggests that similar tools could be repurposed for broader espionage or financial theft, raising concerns for iPhone users worldwide and prompting a reassessment of mobile threat models.Future Outlook: Modular Spyware on the RiseAnalysts predict that the success of Darksword will encourage further development of modular iPhone exploits that prioritize rapid data theft over persistent surveillance. Defensive measures will likely focus on hardening web‑delivery chains, improving app‑store vetting, and enhancing on‑device anomaly detection to counter fleeting, high‑impact attacks.
