This is wild:
Roger Ver... ...was contacted by a hacker who had seized control of his old Hotmail account and used it to nab his Social Security number, passport number, and other personal information. The hacker threatened to exploit this information unless Ver forked over about 37 bitcoins, the equivalent of $20,000. But then Ver used the same number of bitcoins to put out a bounty on the hacker, and this instantly transformed the brazen cyber criminal into a penitent stooge.
“Sir, I am sincerely sorry. I am just a middleman. I was being told what to tell you,” the hacker told Ver soon after the bounty was posted, before later asking: “Are you going to order a hitman to kill me now?”
Off to read the rest now...
Edit: Ver does not threaten to have the guy killed, but since BTC is used for the bounty, the thief assumes the worst. // good article.
