There is a weakness common to any software letting you protect a piece of data with a password: how does that password translate into an encryption key? If that conversion is a fast one, then you better don’t expect the encryption to hold. Somebody who gets hold of that encrypted data will try to guess the password…

“Never answer an anonymous letter” —Yogi Berra Did you ever wonder why doctor offices ask for your social security number?

Its tools are no different from what we have in our world, it’s just better-funded. X-KEYSCORE is Bro plus memory. FOXACID is Metasploit with a budget. QUANTUM is AirPwn with a seriously…
