From Wired, in 2014:
From a distance, the world’s largest bitcoin exchange looked like a towering example of renegade entrepreneurism. But on the inside, according to some who were there, Mt. Gox was a messy combination of poor management, neglect, and raw inexperience.
Its collapse into bankruptcy last week – and the disappearance of $460 million, apparently stolen by hackers, and another $27.4 million missing from its bank accounts – came as little surprise to people who had knowledge of the Tokyo-based company’s inner workings.
…Last week, after a leaked corporate document said that hackers had raided the Mt. Gox exchange, Karpeles confirmed that a huge portion of the money controlled by the company was gone.
…This would be the second time the exchange was hacked. In June 2011, attackers lifted the equivalent of $8.75 million.
And now on July 27th from WizSec, the Bitcoin Security Specialists, who go into detail on the recon work they’ve been conducting for the past six years.
Earlier today news broke of an arrest in Greece of a Russian national suspected of running a large-scale money laundering operation focused on Bitcoin. The man has since been publicly identified as Alexander Vinnik, 38, and over $4 billion USD is said to have been trafficked through the operation since 2011.
We won’t beat around the bush with it: Vinnik is our chief suspect for involvement in the MtGox theft (or the laundering of the proceeds thereof).
