The largest Foxpt exchange was forced to stop its work for 72 hours because of a simple error that allowed to conduct a crypto-currency transaction twice. As a result, the exchange lost about 30BTC (270 000 $) because of dishonest users.
Officials commented this in such a way that the error was detected when users duplicated about 130 output operations. Immediately, the exchange was transferred to emergency services in order to stop withdrawal of funds. Some attackers have already returned the withdrawn funds, other warrants for withdrawal will be suspended until further investigation.
The exchange was not hacked. The amount of missing funds can not affect the activity of the exchange and users will not lose their balances.

Foxbit, Brazil’s largest cryptocurrency exchange, has been down for over 72 hours, reportedly because of a bug that allowed its users to withdraw their bitcoin balances twice. The problem saw the company lose a total of 30 Bitcoins, at press time worth roughly $270,000.
Through a livestream on YouTube, the company’s CEO João Canhada and COO Luís Augusto Schiavon, revealed the bug saw its users take advantage of the exchange’s withdrawal system to duplicate 130 withdrawals. After realizing what was going on, Foxbit immediately launched an emergency maintenance mode to halt withdrawals. The maintenance mode reportedly corrupted some of its service providers’ data.
Per the company’s executives, data is now being restored, and Foxbit should be back up by March 14. Through a blog post, the cryptocurrency exchange informed its users that it wasn’t hacked, and linked back to two cold wallets to show their funds were safe.
