Yes, there are documented cases and significant privacy concerns regarding the misuse of Mobile Device Management (MDM) software for spying on individuals' Android devices. While MDM is designed for legitimate enterprise use, its powerful features can be exploited by threat actors or used by employers in a way that infringes on personal privacy.
Documented cases and attack methods
Malicious enrollment and unauthorized access: In 2024, a user on a Google forum reported that their personal Samsung Galaxy Android phone was maliciously enrolled in an Enterprise Mobility Management (EMM/MDM) solution. This allowed a threat actor to take significant control of the device, reconfigure security settings, and potentially intercept data and verification codes.
Compromised MDM credentials: Cybersecurity firm Group-IB found over 1,500 pairs of stolen login and password credentials for local and public MDM services on the dark web. This type of compromised data, often obtained through malware attacks, could allow threat actors to gain unauthorized access to MDM systems and, consequently, all the devices managed by them.
Employer surveillance: In 2019, a system administrator revealed on Hacker News that it was possible to track employees' whereabouts by default using MDM. The administrator stated that after managing an MDM instance, they would never install it on their personal phone due to the extensive access it provided.
Man-in-the-Middle (MITM) attacks: Installing an MDM policy can enable administrators to perform MITM attacks on Android devices. By forcing SSL decryption through a VPN, an attacker could potentially see browsing history, banking details, and other private conversations.
How MDM can be used for spying on Android
MDM's legitimate administrative capabilities can be repurposed for surveillance. This is particularly concerning when individuals are required to install MDM on their personal phones (Bring Your Own Device, or BYOD). Once installed, the administrator may have the ability to:
Track location: Use the phone's GPS to track the user's location in real-time.
Read text messages: On Android, some setups can route text messages through an SMS gateway, allowing them to be read by an administrator.
Intercept private data: Forcing SSL decryption can enable the interception of encrypted cloud backups and other internet traffic, revealing private photos, videos, and browsing history.
List and manage apps: See a list of installed applications on the device.
Perform remote actions: Remotely lock or wipe the personal phone.
How to protect yourself
Avoid using MDM on a personal device: The most direct solution is to avoid installing MDM policies on your personal phone. If your employer requires it, consider requesting a company-owned device instead.
Use a separate work phone: Use a dedicated company phone for work-related activities. This prevents an employer's MDM from accessing data on your personal device.
Look for signs of compromise: Monitor your phone for suspicious behavior, such as:
Unexplained battery drain or excessive data usage.
Unfamiliar apps or settings.
The screen lighting up randomly.
The "developer options" setting being enabled without your action.
Use mobile security software: Regularly run a scan with a reputable mobile security app that can detect spyware and other malicious software.
Check app permissions: Regularly review the permissions of your apps under Settings > Privacy > Permissions Manager. Look for anything that seems suspicious, such as a seemingly harmless app having access to your microphone, camera, or location.
