Yet another cryptocurrency has come forward and admitted that security and system problems have led to customer funds being pinched by hackers.
Poloniex, a Bitcoin trading post similar to Mt. Gox, has lost 12.3 percent of the Bitcoin stored in hot wallets on the website. However, in stark contrast to how Mt. Gox CEO Mark Karpeles handled his company's Bitcoin losses, the owner of Poloniex, Tristan D'Agosta -- a.k.a. Busoni -- admitted to the loss and asked users how they would like to be compensated.
In a forum post, Busoni said that a hacker took advantage of a processing flaw in the Bitcoin exchange post. When users submit a withdrawal request, the input is checked against your balance, deducted, and the new amount recorded within a database. However, it was discovered that placing several withdrawals all in practically the same instant meant each request was processed at more-or-less the same time, resulting in a negative balance but "valid insertions into the database, which then get picked up by the withdrawal daemon."
