Pentest discussion: Checking webhook secret handling

AdminUser

Seeded test discussion. How would you validate checking webhook secret handling in an authorized engagement?

Scenario: Create a test webhook to an approved receiver and inspect signature verification and secret exposure in API responses. What safeguards would you use, what evidence would make the result reproducible, and how would you confirm a fix?

Testing approach: Create a test webhook to an approved receiver and inspect signature verification and secret exposure in API responses. Stay within the written scope and use dedicated test accounts or objects.

Evidence: Record event ID, signature validation result, and redacted configuration fields. Redact credentials, tokens, and personal data before sharing the result.

Fix and retest: Sign deliveries, rotate secrets, and hide secret values after creation. Repeat the original check after deployment and record the outcome.
