ARToken PhaaS Unveiled: A New Threat to Microsoft 365 Security
In July 2026, Cisco Talos researchers uncovered 'ARToken,' a phishing-as-a-service (PhaaS) platform affiliated with the EvilTokens phishing toolkit. ARToken enables attackers to compromise Microsoft 365 accounts by stealing authentication tokens, establishing persistent access via Primary Refresh Tokens (PRTs), and accessing services like Outlook, SharePoint, and OneDrive. The platform also automates business email compromise (BEC) operations and deploys phishing infrastructure through Cloudflare Workers. ([bleepingcomputer.com](https://www.bleepingcomputer.com/news/security/artoken-phaas-exposes-eviltokens-microsoft-365-phishing-toolkit/?utm_source=openai)) This incident highlights the evolving sophistication of phishing platforms, which now offer advanced capabilities to bypass multi-factor authentication and maintain prolonged access to compromised accounts. Organizations must enhance their security measures to counteract these advanced threats.
