Revolut exposes customer passports and financial data via fake government request

Revolut disclosed that it inadvertently sent personal and financial data of some customers to a threat actor who impersonated a government agency using an authenticated domain. The leaked data reportedly includes identity documents, selfies, account statements, IBAN numbers, and transaction histories, including Bitcoin transactions. Revolut says the breach affects a limited but undisclosed number of accounts and that customer funds remain unaffected.

7.3 Million Chess.com Profiles Leaked, Likely From Data Scraping Not a Breach

A 15.5 GB file containing over 7.3 million Chess.com user records surfaced for free on two data-leak forums, with no ransom attached. Analysis of the archive found genuine, recent Chess.com data including emails, usernames, ratings, and subscription status, but no passwords or payment details, pointing toward large-scale scraping rather than a server intrusion.

Misconfigured Vietnam-linked APIS database exposed 220 million traveler records

Security researchers at Kinryu Labs found an unsecured Elasticsearch cluster in Viettel-assigned IP space in Hanoi containing over 220 million passenger and crew records dating from 2017 to 2026. The exposed data included passport numbers, nationalities, dates of birth, flight details, seat assignments and baggage information, accessible due to a chain of misconfigurations and default credentials. The database was secured after being reported, though it remains unknown whether the data was accessed or copied before that point.

YC's latest Demo Day batch leans deep tech, VCs spotlight nine startups

Y Combinator's newest Demo Day featured a batch skewed heavily toward deep tech, with startups like Atomarine pitching nuclear-powered floating data centers and Dipole Labs building optical networking hardware to cut power waste in AI clusters. TechCrunch surveyed early-stage investors who named nine companies that got flagged repeatedly as the standouts of the cohort. Investors noted the technology felt futuristic, but valuations across the batch were more restrained compared to recent quarters.

Zuckerberg Downplays Cambridge Analytica Scandal in Old Remarks Resurfacing

A widely circulated quote attributed to Mark Zuckerberg suggests he characterized Cambridge Analytica's data practices as nothing unusual, implying similar data harvesting was common industry practice rather than a unique violation. The remark, dated to 2017, has resurfaced without full context around the original scandal that saw millions of Facebook users' data improperly obtained.

AI Industry Faces Wave of Mutual Theft Accusations Amid Data Scraping Practices

Multiple AI companies are now accusing each other of stealing proprietary technology, models, or data, even as the broader industry itself has built its foundation on scraping internet content without explicit consent from original creators. This dynamic has created a contradictory landscape where firms decry theft while relying on similarly extractive practices for their own products.

External SSDs vs HDDs: speed and durability come at a higher cost per gigabyte

External SSDs use flash storage that speeds up file transfers and editing directly from the drive, while offering greater durability, quieter operation, and lower power draw thanks to having no moving parts. External hard drives remain the cheaper option per gigabyte, with examples like a 2TB Seagate HDD costing less than a 1TB Samsung T9 SSD.

Data center boom driven by AI agents, not chatbot queries

AI companies are pouring billions into massive data centers and power plants to support 'agents'—AI systems that autonomously execute multi-step tasks rather than simply answering questions. Unlike a single chatbot query, an agent can generate hundreds of self-prompts to complete complex jobs, such as building an entire website over several hours. OpenAI recently touted a swarm of over 10,000 agents exchanging 2.7 million messages to tackle a longstanding math problem, though mathematicians have disputed the significance of that result.

FTC penalty on GM exposes widespread auto industry data sales to brokers

The FTC banned General Motors for five years from selling customer driving data to consumer reporting agencies after finding the automaker had collected details like speeding and nighttime driving through its OnStar Smart Driver feature and passed them to data brokers LexisNexis and Verisk, which serve insurers. Many drivers say they didn't realize they had consented to this tracking, and some reported their insurance rates rose as a result. Research from the Mozilla Foundation found nearly every major automaker has similarly weak privacy protections and overlapping, confusing consent policies for vehicle data.

Deep dive exposes ThreadSanitizer's blind spots in detecting data races

An in-depth technical analysis examines how ThreadSanitizer, the race detector underlying Clang, GCC, Go, and Swift, actually works internally by walking through data race fundamentals and building a Python-based FastTrack-style vector clock simulation. The piece then demonstrates concrete scenarios where TSan's architecture causes it to miss genuine data races, including a documented failure once a program crosses 255 total threads.

Multiple Router Antennas Exist Because of MIMO Technology, Not Marketing

Modern Wi-Fi routers often ship with multiple antennas—sometimes up to eight—because of a technology called MIMO (multiple-input, multiple-output), which allows several data streams to be handled simultaneously rather than one at a time. This shift away from single-antenna designs was driven by the explosion of internet-connected devices in homes and the growing demand for faster, more reliable connections.

LG rebuts claims its smart TVs secretly record household conversations

LG issued a detailed statement pushing back on a Gamers Nexus investigation alleging its smart TVs capture audio and network data even while asleep or offline. The company said voice processing only activates via a wake word or remote button press, and that features like Automatic Content Recognition and ad targeting are opt-in, not default.
