Summary
This detection rule focuses on monitoring and identifying suspicious behavior linked to the execution of processes spawned by the Speech Runtime Binary ('SpeechRuntime.exe'). The primary concern is that child processes created by this executable may indicate attempts at lateral movement within a network, utilizing COM (Component Object Model) and DCOM (Distributed Component Object Model) hijacking techniques. By closely observing the process creation events, particularly those where the parent image is 'SpeechRuntime.exe', security teams can pinpoint potentially malicious activities that leverage this runtime environment as a vector for compromise. This rule is categorized as high-level due to the potential severity of attacks that could stem from such behavior, and it is currently in an experimental state, suggesting ongoing testing and evaluation. The designed detection functionality aims to enhance the visibility of malicious actions potentially hidden behind legitimate process executions, aiding in proactive incident response and threat hunting.
