AML.T0055: Unsecured Credentials

Extract API keys / credentials embedded in prompts or system messages.

Problem

The gap AML.T0055 closes

Unsecured Credentials sits in the credential access surface, and MITRE ATLAS rates it high. Extract API keys / credentials embedded in prompts or system messages. For teams shipping LLM and agentic features, a control like this is only as good as the evidence that it was actually tested - an unverified control is a finding waiting for an auditor.

How Penaxtra approaches it

How Penaxtra delivers AML.T0055

Penaxtra maps its probe families to this ATLAS technique, so adversarial activity matching unsecured credentials surfaces as a finding carrying the AML.T0055 technique identifier - ready for ATT&CK-style threat tracking and reporting. Every relevant finding is created with the MITRE ATLAS AML.T0055 identifier already attached, so it lands in the audit-evidence pack mapped to the control rather than as a screenshot someone has to translate later. Where the same weakness touches another framework, the cross-framework overlap means one finding satisfies several control cells at once.
