App Repackaging

Decompiling a legitimate app, modifying it (for example adding malware or removing checks), re-signing it and redistributing it.

Definition

Repackaged apps appear in third-party stores and phishing campaigns. Defenses include signature checks, attestation, anti-tampering and monitoring app stores for clones.

Example

A banking app clone with an added credential stealer is distributed through a third-party app store.

Exam tip

Re-signing changes the signing certificate, which integrity checks can detect.
