Low Prevalence Process Launches and Connects to Low Prevalence Domain
This rule detects a suspicious sequence of events: a process launching with a low prevalence executable (meaning it's rarely seen in the environment) followed by that same process initiating an HTTP connection to a low prevalence domain (a domain rarely accessed in the environment) within a 10-minute window. This combination can indicate the execution of novel or custom malware attempting to establish command and control or exfiltrate data to an unusual destination.
