The Federal Bureau of Investigation (FBI) has issued a Public Service Announcement (PSA) warning U.S. smartphone users about potential data security risks posed by foreign-developed mobile applications. The announcement, released at the end of March 2026, highlights concerns over apps developed by companies headquartered outside the United States, particularly those that may collect personal data even when not in active use [1][2].
The FBI’s warning specifically points to apps that request access to contact lists and other personal information, with some potentially storing data on servers located in China for unspecified durations [1][3]. The agency advises users to take several precautions, including disabling unnecessary data sharing, downloading apps only from official app stores, regularly updating passwords, keeping device software current, and thoroughly reading terms of service or end-user license agreements before installing apps [1][2].
Additionally, the FBI has noted that some foreign-developed applications may contain malware capable of exploiting operating system vulnerabilities, installing backdoors, or collecting data beyond what is authorized by the user [1][4]. In response to these risks, the FBI recommends that users file a complaint with the Internet Crime Complaint Center (IC3) if they observe suspicious activity related to a foreign-developed app, such as unusual data usage, battery drain, or unauthorized access [2].
What Is Known
The FBI’s PSA underscores the potential risks associated with certain foreign-developed mobile applications, particularly those from China. The agency has provided specific guidance on how users can protect their data and devices from potential threats [1][2].
What Remains Unclear
While the FBI has highlighted general concerns about foreign-developed apps, it has not provided a specific list of applications to avoid. Some reports have mentioned apps such as CapCut, Temu, SHEIN, and Lemon8, but these claims have not been confirmed directly by the FBI [1].
