Interesting privacy vulnerability: javascript can be used to scan the ports and IP addresses of your local network.

can be mitigated by enabling the
>Block Outsider Intrusion into LAN
blocklist in ublock origin (it's off by default)
@billiam Bonus round:
yun-wuxin:[wisknort]:~/tinker/fedi/TheDesk/app$ curl -sI https://blog.nem.ec/2020/05/24/ebay-port-scanning/ | grep -i server
server: cloudflare
@Zerglingman it seems like the local network stuff can be blocked by ublock origin (although it's not blocked by default so 99.9% of internet users are vulnerable to it (I heard brave recently added some protections too, so there's that)).

Cloudflare MIMT is obviously more difficult to avoid.
@billiam They're both pretty straightforward to avoid, but cucks will cope and seethe when you tell them the solutions.
I haven't bothered to blacklist cuckflare's IPs because I want them to see traffic going to sites that shit on them.

@Zerglingman Most even have WebRTC enabled 🤷
