What is business-logic abuse?¶

Business-logic abuse uses valid application functions in an unauthorised sequence or purpose to defeat the intended process. It may require no software vulnerability and can consist of individually valid requests.

Reconstruct expected and actual workflows¶

Document the normal rules, limits and ordering, then align the actual accounts, sessions, devices, requests and timing. Examples include repeated benefit claims, manipulated refunds, limit avoidance, recovery misuse and coordinated account creation.

The unauthorised result often appears only across the full sequence. Preserve account relationships and automation indicators rather than examining each transaction in isolation.

Connect technical method to business outcome¶

A valid request can be abusive, while an unusual transaction can be legitimate. Compare terms, authority, communications and normal use.

Where financial, entitlement or access impact is alleged, link the request sequence to transaction, account and loss records. Application evidence shows method; business records establish the actual gain, loss or control avoided.
