+Handling code signing certificate reports
+-----------------------------------------
+
+Python signs binaries using Azure Trusted Signing and Apple Developer ID
+certificates. If a code signing certificate is reported as "compromised" or
+"malware signed with certificate", the Python Security Response Team must
+request the following information from the reporter:
+
+* Checksum(s) of binaries signed by certificate.
+* Signature(s) of binaries signed by certificate.
+
+To avoid unnecessary user confusion and churn around revoking code signing
+certificates, any reports **must be verifiable independently by the PSRT before
+taking destructive actions**, such as revoking certificates. With this
+information the PSRT can take investigative steps to verify the report, such as:
+
+* Downloading and checking artifacts from the associated Azure Pipelines
+  executions against the reported list of checksums.
+* Verifying the validity of the signatures. `Past reports
+  <https://discuss.python.org/t/103356/2>`__ have contained signatures that
+  purported to be from Python code signing certificates, but were not valid.
+* Checking the Azure Pipelines and Azure Trusted Signing audit logs for signs of
+  compromise.
+
+If any signs of compromise or incorrectly signed binaries are discovered by the
+PSRT, only then will certificates be revoked and an advisory published.
+If compromise is reported, the following non-destructive actions can be taken by
+the PSRT without verifying the reported information as a precaution, if
+relevant:
+
+* Rotating secrets associated with code signing (``TrustedSigningSecret`` for
+  Azure Trusted Publishing).
+* Resetting passwords for accounts with access to signing certificates.
