Elon Musk Loses His Lawsuit Against OpenAI

(4 newsletters)

A San Francisco jury unanimously dismissed Musk’s $100B+ lawsuit against OpenAI, Sam Altman, Greg Brockman, and Microsoft after a three-week trial packed with leaked texts and billionaire testimony. The jury found Musk waited too long to sue, ruling his claims fell outside the three-year statute of limitations since OpenAI began its for-profit conversion in 2019 and Musk did not file until 2024. OpenAI’s defense argued that Musk had been part of early discussions about going for-profit and only sued after founding his competing lab, xAI. Musk called the verdict a “calendar technicality” and says he will appeal. The clearest winner beyond Altman: the verdict removes a major legal cloud over OpenAI’s reported path to an IPO by 2027.

Claude Mythos Breaks Apple’s M5 Hardware Security in Five Days

(3 newsletters)

A small security research team at Calif used Anthropic’s still-unreleased Claude Mythos model to develop the first public kernel memory corruption exploit bypassing Memory Integrity Enforcement (MIE) on Apple’s M5 chips, completing the work in under a week. Apple built MIE as its strongest-ever defense against memory-based kernel attacks. The researchers were clear that human expertise was essential for the final bypass, but Mythos dramatically accelerated the bug-hunting phase. TLDR separately reported that Cloudflare pointed Mythos at 50+ of its own repositories in a project called Glasswing and found the model to be “a real step forward” that raises new questions about how security should be handled in the near future. The Calif team has hand-delivered a report to Apple and the two are working on a patch.
