It seems odd to have a report with a 5G label and then find information in it about core routers. Yes they play a part but it strikes me as odd that there is no focus on mobile switching, gateways, HLRs, signaling vulnerabilites etc..

When looking at the boxes they compare:

Huawei: CloudEngine 12800 scales up to 2000 * 25GBit or 500 * 40GBit Juniper: EX4650 Ethernet Switch scales up 48*25GBit

With all due respect but this is comparing apples with orange seeds. A carrier class switch is more complex than an enterprise switch and has a much larger attack surface.
