One of the leaders in the cryptomat market, General Bytes, reported a hacker attack on its bitcoin ATMs around the world.
The attackers successfully carried out a zero-day attack on General Bytes servers, taking advantage of a vulnerability in CAS hardware management software. They managed to create a fake administrator account and modify the settings for buying and selling cryptocurrency so that users of devices send digital assets to a wallet owned by criminals.
General Bytes employees asked customers to stop using bitcoin ATMs until specialists make a patch to the software installed on 18 servers.
