Nothing to contribute, bumping for educating other users. This sucks: I thought we'd have a little more time before people tried to pull this.
Honestly, I'm surprised it took this long. The only reason why it never happened before was because the value of the BTC was so low it wasn't worth the time to invest in creating the virus and spamming it. Now that 25,000 BTC is worth $500,000, it seemed it was only a matter of time and we're just getting started. Bitcoin needs some end-user encryption/protection to prevent unauthorized access.
