Structural Memory Patterns (Part 8)

After almost a 6-year break we resume extending the catalog of structural memory patterns as a foundation of pattern-oriented memory forensics, root cause analysis, and software internals. The next pattern we add is borrowed from archaeology and is called Region Strata. When we have several memory snapshots we can analyze Memory Regions for their changes at different times:

For example, we got two memory dumps of the same process saved by WER with approx. one minute difference. We saved the raw stack region of the current thread using .writemem WinDbg command in text files (Strata1.txt and Strata2.txt) and then combined them into one Excel table (Strata.xlsx). In that table we can see memory region changes as shown in this picture (click to expand):
