| Threat Actors | Unknown “foreign-based threat-actor group” operating a hacking-as-a-service scheme called the Azure Abuse Enterprise. |
| Campaign Overview | • Exploited stolen Azure API keys and customer Entra ID credentials. • Used Microsoft’s Azure OpenAI Service to bypass safeguards and generate harmful content. • Monetized access by selling tools to other malicious actors. |
| Target Regions (or Victims) | • U.S.-based companies, including those in Pennsylvania and New Jersey. • Other global AI service providers were also targeted. |
| Methodology | • Systematic API key theft. • Use of de3u and oai reverse proxy to interact with Azure OpenAI Service. • Abuse of Cloudflare tunnels to funnel requests through reverse proxy services. |
| Products Targeted | • Microsoft Azure OpenAI Service. • Other AI platforms like Anthropic, AWS Bedrock, Google Cloud Vertex AI, and OpenAI. |
| Malware Reference | Not explicitly mentioned, but tools like de3u and oai reverse proxy facilitated abuse of stolen credentials. |
| Tools Used | • de3u tool – DALL-E 3 frontend with reverse proxy. • oai reverse proxy service – Enables unauthorized access to Azure APIs. • GitHub repositories and Rentry.org pages for distribution of tools. |
| Vulnerabilities Exploited | • Compromised customer credentials (API keys, Entra ID authentication). • Lack of protections against reverse proxy abuse and API misuse. |
| TTPs | • API key scraping and theft. • Reverse proxy abuse to mimic legitimate Azure API calls. • Deletion of malicious infrastructure post-detection. • Selling unauthorized AI access to other actors. |
| Attribution | Threat actor group linked to broader attacks on Microsoft and other AI providers, leveraging a coordinated infrastructure for malicious activities. |
| Recommendations | • Implement stricter API key management and monitoring. • Harden safeguards against reverse proxy misuse. • Regularly audit systems for unauthorized API calls and stolen credentials. • Collaborate across industries to share threat intelligence. |
