content: "Hacking Team broke Bitcoin secrecy..." this is about stealing Bitcoin not "Secrecy" http://arstechnica.com/security/2015/07/hacking-team-broke-bitcoin-secrecy-by-targeting-crucial-wallet-file/ It is important to note: The wallet.dat file holds the private key, that is the key to "crypto" within the other key is public. most people will protect the wallet.dat with a paraphrase however as stated keyloggers and other malware find this. This means if you are using any crypto on a Wintel system with a single key verification you are vulnerable.
