alt Hacker NewsCool site. I was curious and dropped your 100k list into a reverse DNS lookup site [1]. They may still have some of the records cached. I recognized quite a few of the scanner nodes and some other usual suspects.

Yeah, that’s pretty interesting! You can also see a live view of the ASN/ISP leaderboard by going to https://knock-knock.net and choosing ISP from the carousel. That’s ordered by bot transaction count rather than IP count though.
It never ceases to amaze me that these ISPs don’t bother to shut down the botnets. They could do so very easily. For example, they could identify the IP address of every bot that hit this honeypot with their ASN with one API call: https://api.knock-knock.net/check-asn?asn=<asn number>. (See https://knock-knock.net/api). They just don’t care!
