The Anarchist Cookbook had a recipe for this IIRC, called ANTI (Ammonia Nitrate TriIodide). My chemistry teacher was not pleased at the pits left in the classroom countertops.
Kids - do note that the Anarchist's Cookbook is absolutely verboten in the UK at least. My old man was an ATO so I didn't need a copy.
The original AC will be several elements in every wordlist that every intelligence service ever has. It is probably quite close to EICAR in that world.
I recall reading some story where the author was able to do a denial of service attack on a system by putting EICAR in it, causing a kind of autoimmune dysfunction.
If you skip forward to 16m 33s you'll be treated to a lively streak of invective from the passenger of a car whose driver has just confirmed that feeding EICAR to a parking system prevents it from letting any vehicle past the barrier.
Perhaps, I might read your formal critique?
