Thus far, these agent vulnerabilities are all demonstrating million-monkey intelligence, rather than "super" intelligence, in the sense of some swarm of robo-Neo super hackers.
That's consistent with my experience using them for coding, where even the best models mostly work by being persistently midwit (with infinite knowledge) more than individually brilliant.
One corollary of this is probably that any project that has had an army of actual monkeys pounding on it for years is likely more resistant to LLM attack than one that has not. Everyone is worrying about individual robot geniuses finding obscure vulnerabilities in Linux, PHP, Python, etc., but they should probably be more worried about the permutations of less-known software floating around their systems.
“LLM” may not literally stand for “Lots and Lots of Monkeys”, but this intuition can nevertheless take you pretty far!
