Abstract
A mobile app is in a form of a package file. A structural feature digest is generated from contents of a manifest part, bytecode part, and resource part of the package file. A mobile device receives an unknown mobile app, generates a structural feature digest of the unknown mobile app, and sends the structural feature digests to a backend system over a computer network. In the backend system, the structural feature digest of the unknown mobile app is compared to structural feature digests of known malicious mobile apps. The unknown mobile app is detected to be malicious when its structural feature digest is similar to that of a known malicious mobile app.
