Your ISP knows the Mac address of your router since it requests a public IP from them using DHCP. That’s why if you contact support they usually can confirm the brand of your router by doing an oui lookup.
Comment on Chinese malware removed from SOHO routers after FBI issues covert commands
shalafi@lemmy.world 5 months agoMy ISP has never had info on my router, for 20+ years. Was there something in the story I missed about these being ISP issued routers?

Do you work in networking? How did you learn the magicks of the computer tongue?
BakedCatboy@lemmy.ml 5 months ago
I only do web development, but my networking knowledge mostly comes from being the designated person to call the ISP for tech support and being in charge of setting up the WiFi in every place that I’ve lived, in addition to participating and running community scale mesh wifi tech meetups for many years (think NYCMesh except just 4 guys who never accomplished much aside from buying and flashing lots of routers with openwrt lmao)

Probably works the other way around - FBI detects the problem at various IP addresses, patches them, then contacts the iISP and asks them to contact the customer who had x.y.z IP address

I would imagine you are in the vast minority :)

The ISPs don’t need info on the routers…
The FBI has identified the routers; if they’re able to connect to them and issue commands, they clearly know the IPs of those routers and thus the ISP servicing that IP. The ISP knows which of their customers is/was assigned a particular IP.
