I got a direct hit to a pdf on my website from 185.162.118.81, no referrer. This is something called Global Connections Network, Dedicated Servers. It's a small ASN, only 2k IP's. Spur says the IP has been or is part of a call-back proxy network.

The UA was:

Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/102.0.5005.125 YaBrowser/22.7.1.675 (beta) Yowser/2.5 Safari/537.36

Request headers specify language as en-US.

I get nothing when searching for background info on Yabrowser and/or Yowser.

And - where is everyone? It's gotten too quiet around here...
