AI Model Identifies Over 10,000 Critical Software Vulnerabilities in One Month
In April 2026, Anthropic launched Project Glasswing, utilizing its advanced AI model, Claude Mythos Preview, to autonomously identify vulnerabilities in critical software. Within a month, the initiative uncovered over 10,000 high- or critical-severity flaws across major operating systems and web browsers. Notably, the AI detected a 27-year-old bug in OpenBSD and a 16-year-old issue in FFmpeg, highlighting its unprecedented detection capabilities. This rapid discovery rate has effectively ended the traditional "patch window," as over 99% of the identified vulnerabilities remain unpatched, posing significant risks to global economies, public safety, and national security. The emergence of AI-driven vulnerability discovery tools like Claude Mythos Preview signifies a paradigm shift in cybersecurity. While these tools enhance defensive capabilities, they also compress the timeline between vulnerability discovery and potential exploitation. Organizations must adapt by implementing resilience-based security models, hardening binaries, and adopting runtime protections to mitigate the risks associated with this accelerated threat landscape.

FBI Issues Warning on Kali365 Phishing Platform Targeting Microsoft 365 Users
In April 2026, the FBI identified 'Kali365,' a Phishing-as-a-Service (PhaaS) platform that enables cybercriminals to hijack Microsoft 365 access tokens by exploiting OAuth device code authorizations. Distributed primarily via Telegram, Kali365 allows attackers to bypass multi-factor authentication (MFA) without intercepting user credentials. This method grants persistent access to Microsoft 365 services, including Outlook, Teams, and OneDrive, facilitating data theft, fraud, extortion, and potential ransomware attacks. ([ic3.gov](https://www.ic3.gov/PSA/2026/PSA260521?utm_source=openai))
The emergence of Kali365 underscores a significant shift in phishing tactics, with attackers increasingly leveraging device code phishing to circumvent traditional security measures. This trend highlights the urgent need for organizations to reassess and strengthen their authentication protocols and user education to mitigate evolving threats.
