So, i started working for Cisco shortly after this went down, and it actually changed basically everything about their global supply chain. Anywhere that devices which would be provided to customers were at rest were blanketed by cameras and literally all procurement shipping was changed to overnight (or first overnight for anything near a warehouse) to try to make it functionally impossible to execute the same attack again.

Talk shit about their products all you want, but they were unironically angry about this issue and in classic Cisco fashion threw money at the problem until it went away.
