Bitcoin Hack Leaves Silk Road 2 Drained of All Funds

According to TechCruch, Silk Road 2 moderator Defcon said in a forum post that the perpetrators made use of the known transaction malleability exploit within the Bitcoin protocol to hack the marketplace. The exploit essentially lets a user request the same transaction over and over again, but it will only look like one has occurred – or none at all. So, it’s the perfect siphon. In this case, the hacker(s) made use of six vendor accounts to order from each other, and to find and exploit the vulnerability aggressively. The user names were narco93, ketama, riccola, germancoke, napolicoke and smokinglife.
