Azure DevOps App Secret

Detects Azure DevOps application secret patterns. This pattern is based on a Microsoft Purview built-in sensitive information type. Users already running Purview may prefer to enable the built-in SIT directly, or use this version as a starting point for customisation.

Type

Engine

universal

Confidence

high

Confidence justification

High confidence: structurally constrained pattern with DevOps-specific context keywords reduces false positive rates significantly. Added context gating and exclusion rules improve precision and reduce incidental matches.

Pattern

(?i)(?:devops[._-]?app[._-]?secret|vsts[._-]?secret|ado[._-]?secret|client[._-]?secret)\s*[:=]\s*"?[A-Za-z0-9_.\-]{20,50}"?

Corroborative evidence keywords

Azure DevOps, DevOps, VSTS, app secret, client secret, OAuth, service connection, app registration, api key, api_key, apikey, access key, access token, auth token, authorization, bearer, conn str, connection string, connectionstring, cookie (+45 more)

Proximity: 300 characters

Should match

• devops_app_secret=AAAA0000BBBB1111CCCC2222DDDD3333EEEE — Azure DevOps app secret
• client_secret: "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdef" — DevOps OAuth client secret
• ado_secret="00000000000000000000000000000000" — ADO secret with placeholder value

Should not match

• devops_app_secret="" — Empty secret value
• organization=my-org — Organization name, not a secret
• template example placeholder record identifier — Template/sample context should be excluded even when anchor words are present

Known false positives

• Azure DevOps documentation and pipeline templates with placeholder application secrets. Mitigation: Check for common placeholder patterns and template indicators.
• Generic client secrets for non-DevOps applications. Mitigation: Require proximity to DevOps-specific keywords like VSTS, ADO, or Azure DevOps.
