AI Breaches macOS – How Anthropic Mythos Discovered Zero-Day Vulnerabilities

AI vs Apple – A New Era of Cyber Threats

Security researchers have officially confirmed the use of a specialized AI model from Anthropic, dubbed Mythos, to successfully breach the macOS kernel. This study marks the first documented case where a Large Language Model (LLM) was able to independently identify and exploit vulnerabilities within Apple’s closed ecosystem without prior knowledge of the source code.

How Mythos Operates in the macOS Environment

Unlike traditional fuzzing tools that rely on random inputs, Mythos employs semantic analysis of binary code. The AI is capable of understanding the logic of system calls and finding logical errors in memory management that typically escape automated scanners.

Comparison of macOS Security Analysis Methods
Analysis Method Discovery Speed Exploit Accuracy Closed-Source Analysis
Classic Fuzzing High Low Limited
Manual Reverse Engineering Very Low Very High Full
AI Mythos (Anthropic) High High Full (via binary code)

Technical Specifications of Identified Vulnerabilities

The researchers focused on the IOKit subsystem and graphics kernel drivers. Thanks to Mythos, three critical vulnerabilities were found, allowing the bypass of SIP (System Integrity Protection). This grants an attacker full access to the file system and personal user data.

  • ASLR Bypass: The AI discovered a way to predict kernel memory addresses with over 98% accuracy.
  • Privilege Escalation: Capability to execute code with root privileges via a use-after-free vulnerability.
  • macOS 15 Integration: The exploits successfully worked on the latest versions of the operating system.

Financial Implications and Risks

Experts estimate the cost of discovering such bugs on the dark market exceeds 500,000 USD. However, the use of AI lowers the entry barrier for cybercriminals, as the automation of complex reverse engineering processes becomes accessible to a wider audience.

Apple’s Response and the Future of Security

Apple has already initiated an internal investigation and is preparing emergency security patches. It is expected that future macOS updates will include additional layers of code integrity verification based on machine learning to counter AI-generated attacks. This confrontation marks the beginning of an arms race in cybersecurity, where both sides utilize intelligent algorithms.
