A Longitudinal Study of Cryptographic API: a Decade of Android Malware. (arXiv:2205.05573v3 [cs.CR] UPDATED)

Cryptography has been extensively used in Android applications to guarantee
secure communications, conceal critical data from reverse engineering, or
ensure mobile users' privacy. Various system-based and third-party libraries
for Android provide cryptographic functionalities, and previous works mainly
explored the misuse of cryptographic API in benign applications. However, the
role of cryptographic API has not yet been explored in Android malware. This
paper performs a comprehensive, longitudinal analysis of cryptographic API in
Android malware. In particular, we analyzed $603\,937$ Android applications …
