Yudun hardens commercial Android and iOS apps with code obfuscation, Java2C, DEX/SO protection, and VMP. It focuses protection on core algorithms, authorization logic, and critical business paths, raises reverse-engineering and code-reuse costs, and verifies performance and compatibility on real candidate builds.
Focus protection on algorithms, authorization, protocols, and entitlements instead of applying the most expensive policy to the whole app.
Combine VMP, Java2C, DEX/SO protection, and obfuscation according to the project, with a clear job for each layer.
Test launch, critical flows, crashes, performance, and target systems on the actual deliverable, not on a configuration preview.
A four-level assessment of a Yudun Android candidate separated recoverable material from program structure, invocation relationships, and algorithmic equivalence.
Read the full assessmentScope: This is a redacted assessment of one candidate, not a universal result for every app, version, or attack condition.
Identify the algorithms, authorization, and protocol paths whose recovery would cause business loss.
Configure the scope in the real build chain and keep comparable, recoverable candidates.
Run performance, compatibility, and critical-flow regression on the same candidate before delivery.
Define the scope of VMP protection across five dimensions: business assets, attacker ROI, execution frequency, blast radius, and release candidate acceptance. Includes actionable configuration and regression strategies.
Usually not. Prioritize code with clear value to an attacker and a path that can be tested independently.
Obfuscation changes names, structure, or control-flow readability. VMP further changes the execution representation of selected code, with a different acceptance cost.
No. It raises analysis and reuse cost. Outcomes still depend on implementation, scope, runtime conditions, and server-side policy.
Prepare the candidate build, critical paths, performance baseline, compatibility range, and rollback version before selecting functions.
