McDonald’s AI Hiring Bot Exposed Millions of Applicants' Data to Hackers Using the Password ‘123456’

wired.com Andy Greenberg 2026-02-04 23:28:50

If you want a job at McDonald’s today, there’s a good chance you'll have to talk to Olivia. Olivia is not, in fact, a human being, but instead an AI chatbot that screens applicants, asks for their contact information and résumé, directs them to a personality test, and occasionally makes them “go insane” by repeatedly misunderstanding their most basic questions. Until last week, the platform that runs the Olivia chatbot, built by artificial intelligence software firm Paradox.ai, also suffered fr

The Petkit Purobox Ultra is $250 off for Prime Day

wired.com Molly Higgins 2026-02-04 23:47:17

This automatic litter box, the Petkit Purobot Ultra (8/10, WIRED Recommends) from pet tech leader Petkit, dares to ask the question: Have we gone too far (as a pet-obsessed society)? This automatic litter box uses a camera to monitor litter box usage, logging every time your pet has used it, and even shows your cat’s stool so you can closely monitor their health to more easily see when something seems amiss. It's normally $1,000—we've tracked it at that price for most of the last three months—

Samsung’s 7th-gen foldables slim down, may finally fit in your pocket

There's no denying annual smartphone releases have settled into a routine—flat glass slabs with slightly faster processors and better cameras. Foldable phones buck the trend, but these products come with plenty of drawbacks. They're big and heavy, and even with all that bulk, the battery life and cameras can be lacking. Samsung's new Galaxy Z Fold 7 and Z Flip 7 don't right all the wrongs, but they mark the most significant year-to-year upgrade since the company began making foldables. The new

A New Kind of AI Model Lets Data Owners Take Control

wired.com Will Knight 2026-02-05 03:59:23

A new kind of large language model, developed by researchers at the Allen Institute for AI (Ai2), makes it possible to control how training data is used even after a model has been built. The new model, called FlexOlmo, could challenge the current industry paradigm of big artificial intelligence companies slurping up data from the web, books, and other sources—often with little regard for ownership—and then owning the resulting models entirely.

This Linux distro makes openSUSE accessible to all - even newbies should take a look

Jack Wallen / Elyse Betters Picaro / ZDNET OpenSUSE is a powerful operating system, but I still haven't recommended it to new Linux users. Why? It's too powerful, and it doesn't include essential day-to-day software. That's a shame, because openSUSE is also very reliable, stable, and secure.

2025 Volvo EX90: A low-key luxury electric SUV

Volvo was among the very first of the global automakers to declare plans to build an all-electrified future. Note the choice of word—electrified, not electric, as it includes hybrids, both plug-in and mild. When it comes to pure electric vehicles, the Swedish automaker has something of a two-pronged strategy. At the low end, there's the diminutive EX30 and EX30 Cross Country, a pair of stripped-down crossovers whose value proposition might be entirely different in light of tariffs and the end of
