RetoSwap said it paused trading after receiving a report at 2:02 AM (UTC+8) that the Haveno trading protocol was under attack.
According to ChainCatcher, RetoSwap said it raised the minimum client version to 2.0 using a filter function, halted trading, and banned the attacker’s onion address.
RetoSwap said its own team was not attacked and that the vulnerability was at the Haveno protocol layer. It added that losses appeared limited to large crypto-asset listings, while fiat traders were not affected.
The team said it is evaluating options to help affected traders recover and that trading will resume after the protocol is fixed.
On May 21, RetoSwap was previously reported to have lost about $2.7 million due to a Haveno protocol vulnerability.
