Second worst hack. The worst one was when the FBI and NSA worked together to install the backdoors that China uses today, and then exploited them for warrentless surveillance for years without any significant criticism.
The NSA does have a program to intercept traffic [2]. But that's not what got hacked here.
I do blame CISA and NSA though for not protecting the system well enough.
