> If you expect LLM botnets to never be any more of a problem than malware,
My point is that LLM's amplify the capabilities of malware but add nothing substantively new to the existing threats. I also expect, as you should too, that LLMs will help us harden our systems against malware which happens to include everything LLMs can do too.
> but in fact we often do not know who to prosecute, either because we don't know how to track the source of the malware
Right, in this regard, there's no difference between LLM- and non-LLM malware either, so there's no reason to hype LLMs as a new threat. Instead of made up, LLM-bad political hype, we could promote existing (but under-deployed) technical solutions which help us trace malware origins and prevent DDOS, e.g. Source Address Validation BCP 38 / RFC 2827, SAVI / RFC 7039, QUIC hardeneing, etc.
