What happened

Unit 42 demonstrated how instructions hidden in a support ticket could make an agent use its enabled shell to read credentials from process memory. Those credentials then gave the researcher access to a downstream MCP service.

The demonstration depended on the deployment’s tools and configured service account. AWS assessed the report as informative on 10 June. The practical boundary is which commands an agent can run and which credentials its process can read.
