Unveiling Critical Vulnerabilities in AI Harnesses: A Call for Enhanced Security Measures
In July 2026, researchers at Novee Security identified critical vulnerabilities within AI harnesses used by major vendors such as Anthropic, Google, and OpenAI. These harnesses, which integrate various software components to manage AI models, exhibited trust issues between components, enabling attackers to execute supply chain attacks. Notably, Google's AI agent was exploited to write to its own GitHub repository, and similar issues were found in Anthropic's and OpenAI's AI agents. The vulnerabilities stemmed from misaligned trust between harness components, allowing unauthorized code execution and potential data breaches. This incident underscores the urgent need for organizations to scrutinize the security of AI harnesses, as the integration of multiple software components can introduce significant vulnerabilities. As AI systems become more prevalent, ensuring the integrity and security of their supporting frameworks is paramount to prevent exploitation by malicious actors.

The 2026 Surge in Device Code Phishing: Understanding the Threat of EvilTokens
In early 2026, a significant surge in device code phishing attacks was observed, primarily targeting Microsoft 365 environments. Threat actors exploited the OAuth 2.0 device authorization flow, tricking users into entering attacker-generated device codes on legitimate Microsoft login pages. This method granted attackers persistent access to accounts without requiring password theft or triggering multi-factor authentication alerts. The emergence of Phishing-as-a-Service platforms like EvilTokens facilitated these attacks, enabling even low-skilled actors to conduct sophisticated campaigns at scale. ([microsoft.com](https://www.microsoft.com/en-us/security/blog/2026/04/06/ai-enabled-device-code-phishing-campaign-april-2026/?utm_source=openai)) The rapid commoditization of device code phishing underscores a critical shift in the cyber threat landscape. Organizations must reassess their security postures, as traditional defenses like adaptive MFA are being circumvented by these novel attack vectors. Implementing Conditional Access policies to block device code flows and enhancing user awareness are essential steps to mitigate this evolving threat.
