Precisely. The list of attacks (?) described in the email is an assemblage of meaningless phrases (like "favicon XML injection" and "JS stochastic Templating") and unrelated occurrences ("Solarwinds Oct/2020").
That kind of gibberish is actually a symptom of psychosis (thought disorder).
I've interacted with a few people with psychotic illness over the years (both in-real-life and online) and the distinctive language style is rather hard to miss.
