The FBI has attributed a cryptocurrency heist valued at $6.3 billion to North Korea, Al Jazeera English reported. The outlet described the theft as a record-setting crypto heist. Binance says it has covered 90 percent of the losses from the hack. Both claims come from a single report and have not been independently verified. It is not known how the hack was carried out or when it took place. It is also not known which platforms or users were affected, or what evidence the FBI relies on to blame North Korea. How Binance is covering the losses, and what happens to the remaining 10 percent, is not known either.
