API Security Assessment

Engagement Objectives

• Validate OAuth 2.0 and token handling
• Test object-level authorization on payment routes
• Assess rate limiting and abuse resistance

Approach

We began with a scoping workshop to align on in-scope assets, rules of engagement, and success criteria. Over the following weeks, our consultants applied a manual-first methodology aligned to API Security Testing, validating every finding before reporting and coordinating closely with the client's engineering team.

Outcome

We demonstrated unauthorized access to transaction history via a BOLA flaw and recommended schema enforcement and per-object checks. All findings were remediated within the sprint cycle.
