DET0655 Detection of Command and Scripting Interpreter

AN1741 Analytic 1741

For Android, detect Command and Scripting Interpreter from documented management, network, or vetting evidence; treat state queries as periodic observations rather than real-time events. Correlate Command Execution via Application Vetting / Instrumented Dynamic Analysis [Dynamic API/runtime trace: App spawns sh, bash, toybox, toolbox, or su child process with command arguments within $ShellActivityWindow$ of shell launch — child shell process with arguments is the script execution signal]; Process Creation via Application Vetting / Managed Device Telemetry [App invokes Runtime.exec(), ProcessBuilder.start(), or JNI-backed command execution framework to spawn shell or command interpreter process NOT IN $ApprovedShellApps$ — programmatic shell spawn is the interpreter invocation]. Alert on a sequence or state change inconsistent with the device/app baseline, approved management policy, or expected user workflow; do not infer unobserved API calls, file/process activity, or payload content from management state alone.

AN1742 Analytic 1742

For iOS, detect Command and Scripting Interpreter from documented management, network, or vetting evidence; treat state queries as periodic observations rather than real-time events. Correlate Command Execution via Application Vetting / Instrumented Dynamic Analysis [Dynamic API/runtime trace: Shell process (sh, bash) or command-executing child process spawned under app context on supervised iOS device — any shell spawn on stock iOS indicates jailbreak or kernel exploit]; Process Creation via Application Vetting / Managed Device Telemetry [Managed iOS app invokes lower-level process-launch behavior or command-execution-equivalent activity outside sandbox-permitted APIs on supervised device]. Alert on a sequence or state change inconsistent with the device/app baseline, approved management policy, or expected user workflow; do not infer unobserved API calls, file/process activity, or payload content from management state alone.
