Microsoft said it has detected a new variant of XCSSET, a powerful macOS malware family that has targeted developers and users since at least 2020. The variant, which Microsoft reported Monday, marked the first publicly known update to the malware since 2022. The malware first came to light in 2020, when security firm Trend Micro said it had targeted app developers after spreading through a publicly available project the attacker…

X, the social platform formerly known as Twitter, is seemingly blocking links to Signal, the encrypted messaging platform, according to journalist Matt Binder and other firsthand accounts. Binder wrote in his Disruptionist newsletter Sunday that links to Signal.me, a domain that offers a way to connect directly to Signal users, are blocked on public posts, direct messages, and profile pages. Error messages—including “Message not sent,” “Something went wrong,” and profiles…

Researchers have uncovered a sustained and ongoing campaign by Russian spies that uses a clever phishing technique to hijack Microsoft 365 accounts belonging to a wide range of targets, researchers warned. The technique is known as device code phishing. It exploits “device code flow,” a form of authentication formalized in the industry-wide OAuth standard. Authentication through device code flow is designed for logging printers, smart TVs, and similar devices into…

Working at the intersection of Apple’s newest hardware and Linux kernel development, for the benefit of a free distribution, was never going to be easy. But it’s been an especially hard couple of weeks for Hector Martin, project lead for Asahi Linux, capping off years of what he describes as burnout, user entitlement, and political battles within the Linux kernel community about Rust code. In a post on his site,…

The GeForce RTX 5090 and 5080 are both very fast graphics cards—if you can look past the possibility that we may have yet another power-connector-related overheating problem on our hands. But the vast majority of people (including you, discerning and tech-savvy Ars Technica reader) won’t be spending $1,000 or $2,000 (or $2,750 or whatever) on a new graphics card this generation. No, statistically, you (like most people) will probably end…

There was a time when it felt like you needed a streaming subscription in order to contribute to watercooler conversations. Without Netflix, you couldn’t react to House of Cards’ latest twist. Without Hulu, you couldn’t comment on how realistic The Handmaid’s Tale felt, and you needed Prime Video to prefer The Boys over the latest Marvel movies. In the earlier days of streaming, when streaming providers were still tasked with…

There’s a growing collaboration between hacking groups engaging in espionage on behalf of nation-states and those seeking financial gains through ransomware and other forms of cybercrime, researchers noted this week. There has always been some level of overlap between these two groups, but it has become more pronounced in recent years. On Tuesday, the Google-owned Mandiant security firm said the uptick comes amid tighter purse strings and as a means…

Last night, Apple posted a new support document about migrating purchases between accounts, something that Apple users with long online histories have been waiting on for years, if not decades. If you have movies, music, or apps orphaned on various iTools/.Mac/MobileMe/iTunes accounts that preceded what you’re using now, you can start the fairly involved process of moving them over. “You can choose to migrate apps, music, and other content you’ve…

Micro LED has become one of the most anticipated display technologies for consumer products in recent years. Using self-emissive LEDs as pixels, the backlight-free displays combine the contrast-rich capabilities of OLED with the brightness and durability potential of LCD-LED displays, and they avoid burn-in issues. We’re often asked about the future of Micro LED and when display enthusiasts can realistically expect to own a TV or monitor with the technology….
