| contents | With the development of foundation AI technologies, task-executable voice assistants (VAs) have become more popular, enhancing user convenience and expanding device functionality. Android task-executable VAs are applications that are capable of understanding complex tasks and performing corresponding operations. Given their prevalence and great autonomy, there is no existing work examine the privacy risks within the voice assistants from the task-execution pattern in a holistic manner. To fill this research gap, this paper presents a user-centric comprehensive empirical study on privacy risks in Android task-executable VA applications. We collect ten mainstream VAs as our research target and analyze their operational characteristics. We then cross-check their privacy declarations across six sources, including privacy labels, policies, and manifest files, and our findings reveal widespread inconsistencies. Moreover, we uncover three significant privacy threat models: (1) privacy misdisclosure in mega apps, where integrated mini apps such as Alexa skills are inadequately represented; (2) privilege escalation via inter-application interactions, which exploit Android's communication mechanisms to bypass user consent; and (3) abuse of Google system applications, enabling apps to evade the declaration of dangerous permissions. Our study contributes actionable recommendations for practitioners and underscores broader relevance of these privacy risks to emerging autonomous AI agents. |
