The "Janus" Android vulnerability (CVE-2017-13156) allows attackers to modify the code in applications without affecting their signatures. The root of the problem is that a file can be a valid APK file and a valid DEX file at the same time. The vulnerability allows attackers to inject malware into legitimate application and avoiding detection.
