Secret backdoor found in networking gear perfect for government espionage

That's quite a bug -- I expected to see obscure exploit deep in the networking code which masterfully bypasses all code hardening, but found a default credentials instead. This is the kind of mistake that a random IoT company would do, I would not expect this from Cisco.

I don't understand how this could happen in 2019. There were multiple people involved who coded, reviewed, tested the code, signed off on the release.

The other possible explanation is that it's intentional.
