In case you missed it, this is an interesting paper how how to frustrate
a few free memory forensic tools using one-byte modifications to main
computer memory:

The paper examines potential single points of failure in 3 free memory
forensic tools:
1. Volatility
2. Memoryze
3. Responder Community Edition
The reliability of memory forensic tools (both acquisition and analysis)
is a topic which to date has received very little attention (except on
the part of the "bad guys"). Hence, this paper provides some welcome
relief. The paper is marred however by its focus exclusively on free
tools. The commercial tools which cost $10K or $100K also may have
defects and it would be interesting to know how they compare to the free
tools. As I remember it, at least one of the commercial tools has a
license provision which prevents you from telling anyone if you find a
defect. So perhaps the author limited his focus due to legal constraints.
