Identifies unusual parent-child process relationships that can indicate malware execution or persistence mechanisms.
Malicious scripts often call on other applications and processes as part of their exploit payload. For example, when a
malicious Office document runs scripts as part of an exploit payload, Excel or Word may start a script interpreter
process, which, in turn, runs a script that downloads and executes malware. Another common scenario is Outlook running
an unusual process when malware is downloaded in an email. Monitoring and identifying anomalous process relationships is
a method of detecting new and emerging malware that is not yet recognized by anti-virus scanners.
