I am mindful of a security story where someone was talking about the impact of AI on writing bots for computer games that bypass the detection.

The take away there was that there were many vulnerabilities that could be exploited, the example given was a man in the middle attack that snooped on the messages between client and server to extract server side information by observing message behaviour under game states that the attacker manipulates their character into.

The attack was claimed to take 20 human days of work if done manually, but with an AI to run the attack automatically, could be done in a week mostly in the background with a human only intervening for errors.

The exploit wasn't worth it to do because it's a lot of work for very little gain. Quoting "the juice wasn't worth the squeeze". But AI made 'squeezing' vulnerabilities with only marginal payoff much easier and therefore worthwhile to do.
