An additional reason to think there’s many attackers: I submitted this to Reddit and a Redditor says they use these sorts of ‘reverse proxy’ services regularly and that they’ve been discussed overtly on 4chan for at least a year: https://www.reddit.com/r/MediaSynthesis/comments/1fvd6tn/recent_wave_of_llm_cloud_api_hacks_motivated_by/lqb7lzf/ Obviously, if your attacker really was a newbie given their slipups, but these hackers providing reverse proxies have been operating for at least a year at sufficient scale as to generate regular discussions on 4chan alone, then there are probably quite a lot of them competing.
