Anti-tamper checks look for departures from an application's expected integrity. Producing an alert and protecting a critical function require separate verification.
Evaluation approach
Assess signature, code and resource checks against the package users actually receive. Document how store packaging relates to the files produced after protection.
Application example
For a controlled modification to an approved test package, capture the application event, server outcome and user-visible screen together.
Limits and considerations
A check performed only on first launch may not cover interference introduced later during execution.
At what level are you looking for a change?
Changing a package file, changing the installation signature and changing behavior in memory are distinct tests. A successful package check does not establish that the same function remains unaffected at runtime. State the scope alongside the test target.
A small test modification to a protected file can change several conditions at once. If both content and signature change, the triggering control may be unclear. Experiments that limit variables produce more explainable results and make product comparisons more useful.
Checks and decisions
- Separate file and memory coverage
- Verify the distributed signature
- Investigate untested flows
