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.
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
My 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?
The ISPs don’t need info on the routers…
