Code Signature Fields

edit

These fields contain information about binary code signatures.

Code Signature Field Details

edit

Field	Description	Level
code_signature.exists	Boolean to capture if a signature is present. type: boolean example: `true`	core
code_signature.status	Additional information about the certificate status. This is useful for logging cryptographic errors with the certificate validity or trust status. Leave unpopulated if the validity or trust of the certificate was unchecked. type: keyword example: `ERROR_UNTRUSTED_ROOT`	extended
code_signature.subject_name	Subject name of the code signer type: keyword example: `Microsoft Corporation`	core
code_signature.trusted	Stores the trust status of the certificate chain. Validating the trust of the certificate chain may be complicated, and this field should only be populated by tools that actively check the status. type: boolean example: `true`	extended
code_signature.valid	Boolean to capture if the digital signature is verified against the binary content. Leave unpopulated if a certificate was unchecked. type: boolean example: `true`	extended

Field Reuse

edit

The code_signature fields are expected to be nested at: dll.code_signature, file.code_signature, process.code_signature.

Note also that the code_signature fields are not expected to be used directly at the root of the events.
