Binance said on Thursday that a security breach had affected an estimated $6.3 billion in assets, potentially making it the biggest cryptocurrency heist on record. The world's largest crypto exchange said it had recovered or frozen about $3 billion of the affected assets. The incident sent Bitcoin and other digital currencies lower, according to France 24. BBC World reported that two analytics firms have attributed the incident to a North Korean hacking unit called TraderTraitor. The attribution has not been detailed further in the available reporting, and Binance's own account of how the breach occurred had not been published in the sources reviewed. The scale of the losses and the recovery effort remain the central facts of the story.
