At least two prominent bitcoin exchanges were targeted by cyberattacks that interrupted normal operations and trading.
BTC-e and Bitfinex were targeted by distributed denial-of-service (“DDoS”) attacks, a form of cyberattack which typically uses multiple compromised systems to flood a target with message traffic that exceeds its processing capacity. The attacks temporarily disrupted service for both exchanges but reportedly did not cause a loss of funds or protected information. According to a CNBC report, service interruptions like those caused by the DDoS attacks could allow traders to “manipulate the bitcoin market.”
Both exchanges have resumed normal service.
