AN1838: Analytic 1838
Application vetting services could detect applications trying to modify files in protected parts of the operating system. Verified Boot can detect unauthorized modifications to the system partition.[1] Android’s SafetyNet API provides remote attestation capabilities, which could potentially be used to identify and respond to compromised devices. Samsung Knox provides a similar remote attestation capability on supported Samsung devices.
Analyst context for executives and security teams
This analytic is about confirming whether Android devices and applications show signs of tampering with protected operating system areas. For leaders, the decision value is not simply “detect modified files,” but whether mobile security processes can distinguish trusted devices from compromised or non-compliant ones before they access business data.
Executive priority
Prioritize this where Android devices are used for enterprise access, regulated data, field operations, or executive communications. The key business question is whether mobile access decisions are backed by verifiable device integrity evidence, such as application vetting, Verified Boot, or remote attestation capabilities, rather than user trust alone.
Technical view
For Android environments, validate whether application vetting services can identify apps attempting to modify protected OS file locations. Also confirm whether device integrity signals from Android Verified Boot and remote attestation mechanisms such as SafetyNet API or Samsung Knox on supported Samsung devices are available to SOC, mobile device management, or incident response workflows. ATT&CK provides no separate detection logic for this analytic, so local implementation details determine practical coverage.
Likely telemetry
- Android application vetting results
- Device integrity or boot-state signals from Android Verified Boot
- Remote attestation responses from SafetyNet API where used
- Samsung Knox remote attestation results on supported Samsung devices
- Mobile device compliance or enrollment status
Detection direction
- Validate that protected OS modification attempts are surfaced by app vetting or mobile security tooling, not only blocked silently.
- Correlate attestation failures or compromised-device indicators with device identity, user identity, application inventory, and business access decisions.
- Tune workflows to account for legitimate device states, unsupported Samsung Knox coverage, unavailable SafetyNet usage, or unmanaged Android devices.
- Treat lack of official ATT&CK detection text as a reason to test locally with approved validation methods and documented expected signals.
Mitigation priorities
- Establish policy requiring Android device integrity validation before access to sensitive enterprise resources.
- Use application vetting to reduce the likelihood of apps that attempt protected OS modification reaching managed devices.
- Where supported, incorporate Verified Boot and remote attestation outcomes into mobile compliance and response workflows.
- Define incident response actions for failed attestation or suspected OS tampering, such as access restriction, investigation, or device remediation according to enterprise policy.
Analyst notes and limits
This object is a mobile ATT&CK detection analytic for Android. It references application vetting, Android Verified Boot, SafetyNet API remote attestation, and Samsung Knox remote attestation. No ATT&CK tactics, relationships, or official detection procedure were supplied, so the practical recommendation is to validate whether these integrity signals are collected and operationalized in the local environment.
The supplied ATT&CK object does not provide tactics, relationship context, procedure examples, or detailed detection logic. It supports Android only. Coverage depends on device management state, supported hardware or vendor features, and whether attestation or vetting data is actually integrated into security operations.
