Masquerade as Legitimate Application
An adversary could distribute developed malware by masquerading the malware as a legitimate application. This can be done in two different ways: by embedding the malware in a legitimate application, or by pretending to be a legitimate application. Embedding the malware in a legitimate application is done by downloading the application, disassembling it, adding the malicious code, and then re-assembling it. The app would appear to be the original app, but would contain additional malicious functionality. The adversary could then publish the malicious application to app stores or use another delivery method. Pretending to be a legitimate application relies heavily on lack of scrutinization by the user. Typically, a malicious app pretending to be a legitimate one will have many similar details as the legitimate one, such as name, icon, and description. Malicious applications may also masquerade as legitimate applications when requesting access to the accessibility service in order to appear as legitimate to the user, increasing the likelihood that the access will be granted.
