Query: A Blockchain-based Framework for Detecting Malicious Mobile Applications
  in App Stores   The dramatic growth in smartphone malware shows that malicious program
developers are shifting from traditional PC systems to smartphone devices.
Therefore, security researchers are also moving towards proposing novel
antimalware methods to provide adequate protection. This paper proposes a
Blockchain-Based Malware Detection Framework (B2MDF) for detecting malicious
mobile applications in mobile applications marketplaces (app stores). The
framework consists of two internal and external private blockchains forming a
dual private blockchain as well as a consortium blockchain for the final
decision. The internal private blockchain stores feature blocks extracted by
both static and dynamic feature extractors, while the external blockchain
stores detection results as blocks for current versions of applications. B2MDF
also shares feature blocks with third parties, and this helps antimalware
vendors to provide more accurate solutions.
