Security researchers, aided by Anthropic's Mythos, claim to have breached macOS — 2026-05-15

## Short Segments Iceotope secures $26 million to tackle AI's cooling challenges. As AI hardware demands outpace traditional air cooling, Iceotope's precision liquid cooling technology is gaining traction. The British company has closed a Series B funding round led by Barclays Climate Ventures and Two Seas Capital, with existing investors also participating. This funding will help Iceotope expand its product line and patent portfolio, addressing the thermal bottlenecks in next-generation AI infrastructure. As AI systems grow more powerful, the need for efficient cooling solutions becomes critical. Iceotope's technology offers a promising alternative to air cooling, which struggles to keep up with the increasing rack power densities. This development highlights the growing importance of innovative cooling solutions in the AI hardware landscape. GitHub raises the bar for its bug bounty program. As the volume of submissions increases, GitHub is tightening its criteria for what constitutes a strong submission. The platform has seen a rise in reports that lack real security impact, prompting a shift towards more stringent evaluation standards. This move aims to ensure that only submissions with a working proof of concept and demonstrated security impact are considered. By refining its bug bounty program, GitHub seeks to maintain its commitment to collaboration with the security research community while addressing the challenges posed by the growing number of submissions. This change reflects a broader industry trend towards higher standards in bug bounty programs. The UK's tax authority turns to AI to combat fraud. His Majesty's Revenue and Customs (HMRC) is leveraging artificial intelligence to enhance its fraud detection capabilities. The AI system will analyze social media posts and tax return disclosures to identify potential tax evasion. While AI will play a significant role, human staff will still review the findings to ensure accuracy. This initiative is part of HMRC's broader strategy to modernize its operations and improve efficiency. By incorporating AI, HMRC aims to better target fraud and evasion, ultimately increasing revenue for public services. This development underscores the growing role of AI in government operations and its potential to transform traditional processes. Apple reportedly tests Intel's 18A-P process for future chips. In a move that could diversify its chip supply, Apple is exploring Intel's 18A-P process for iPhone, iPad, and Mac chips. This collaboration marks a potential shift from Apple's long-standing partnership with TSMC. While initial production trials are set for 2026, TSMC will continue to manufacture most of Apple's chips. By testing Intel's technology, Apple aims to ensure a more resilient supply chain for its devices. This development highlights the strategic importance of chip manufacturing partnerships in the tech industry. ## Feature Story Security researchers claim to have breached macOS using Anthropic's Mythos AI. This breakthrough has significant implications for Apple's security measures. Researchers from a Palo Alto-based security company used Mythos to uncover vulnerabilities in macOS, one of the most secure operating systems. The exploit, a privilege escalation attack, bypassed Apple's Memory Integrity Enforcement, a defense system designed to prevent memory corruption exploits. This discovery is notable as Apple has invested years in strengthening its Mac security. The researchers' success in breaching macOS highlights the potential of AI-assisted vulnerability research to expose deep-rooted security flaws. Anthropic's Mythos AI has already made waves in the tech and financial sectors by revealing widespread software vulnerabilities. Its application in this case demonstrates the model's capability to identify and exploit security weaknesses in even the most fortified systems. The use of AI in cybersecurity research is not new, but Mythos's success in breaching macOS underscores the evolving landscape of cybersecurity threats. As AI models become more sophisticated, they present both opportunities and challenges for security professionals. Apple is taking these claims seriously and is investigating the reported vulnerabilities. The company's response will likely involve patching the identified flaws and reinforcing its security measures. This incident serves as a reminder of the ongoing arms race between security researchers and software developers. As AI continues to advance, it will play an increasingly pivotal role in both identifying and defending against cyber threats. The implications of this breach extend beyond Apple, signaling a need for the tech industry to adapt to the growing capabilities of AI in cybersecurity.
