TECHNIQUES FOR TRACKING EXECUTABLE IMAGES ACROSS FORKING OPERATIONS

A creation of a first process is detected in a kernel space of the operating system executing on a computing device. An exec parent of the first process is determined. The exec parent identifies a second process within an ancestry of the first process that last performed an exec operation prior to the creation of the first process. A unique process identifier (UPID) associated with a process identifier (PID) of the first process is generated. The UPID is associated with the exec parent in a first mapping store that maps the PID to the UPID. Process activity of the first process executing in the operating system is tracked to generate process activity data that comprises the exec parent.
