I”m curious about the email systems referred to in the TV4 program this evening. Would, in theory, the NSA have the CA self-destructing emails? It seems possible, maybe even probable, that the NSA was hoovering CA during this period, no? If CA assumed that they couldn”t/wouldn”t get caught, those emails might be interesting. “In one exchange Alexander Nix revealed the company used a secret self-destructing email system that leaves no trace. He said: “No-one knows we have it, and secondly we set our… emails with a self-destruct timer… So you send them and after they’ve been read, two hours later, they disappear. There’s no evidence, there’s no paper trail, there’s nothing.”
Interesting. I guess in theory you could have a retention policy to delete all emails after one day or even hours. I bet the users would love that.
