Welcome to Tech Beat. Here's what's moving in technology today.
Mac users are being warned about a sophisticated malware campaign that hijacks OpenAI's reputation to steal passwords. Criminals used stolen Google ad accounts and fake Google Sites pages to lure victims into pasting malicious Terminal commands, deploying a nasty piece of software called the AMOS infostealer. The Windows download button on those pages was a decoy — only the Mac payload was ever real.
Shifting to a milestone worth marking, Linux turned thirty-five years old today. Back in August of nineteen ninety-one, a then-unknown Finnish computer science student named Linus Torvalds posted a casual note about a hobby operating system he'd been quietly building since April. That project started with roughly ten thousand lines of code. It now spans forty million, and quietly runs most of the world's servers, smartphones, and critical infrastructure.
And there's a sobering signal from the memory chip business. At the Hot Chips conference this week, Micron revealed that high-bandwidth memory — the kind powering AI systems — now requires three times the silicon of standard DDR five. That penalty grows with every new generation, meaning AI's appetite for memory is making an already expensive component even pricier.
