Coinrail, a cryptocurrency exchange based in South Korea, said on Sunday its platform has been hacked, with other sources suggesting it lost cryptocurrencies totaling as much as $40 million in the attack.
According to its website, the exchange has already suspended services after it suffered what it calls a "cyber intrusion," which resulted in a range of ERC-20 based tokens stolen from the platform.
However, Coinrail only provided the names of some of the tokens that were taken in the alleged breach without disclosing the exact amounts at stake. These included the NPXS token from the Pundi X project, ATC from Aston and the NPER project's NPER token.
However, a blog post published by Pundi X on Sunday suggested that the hacker may have stolen 1,927 ether, 2.6 billion NPXS, 93 million ATX and 831 million DENT coins, as well as significant amounts of six other tokens.
