Many of those user-agents listed are often faked. Look up which ASN owns their IP. If I block most VPS providers most of the faked bots vanish. There are still some running from residential and phones using hijacked code (readers that are not really just readers but really multipurpose proxies). On that note, do not trust the linked source code but rather decompile the live code your phone is running and have AI analyze it.

Someone is always running mass vulnerability scans. That's a "water is wet" state of the Internet.

Every server with port 80/443 open has thousands of hits a day from random boxes looking for wordpress login pages. The only new thing is that they're pretending to be a different type of annoying bot. There's a new layer of sophistication and subterfuge, but it's the same junk traffic we've always dealt with.
