The cryptocurrency exchange eXch has been implicated in money laundering activities linked to North Korea's Lazarus Group, following a major hack of Bybit that resulted in the theft of approximately $1.4 billion. Bybit's request for cooperation with eXch was rejected, leading to accusations that eXch is laundering funds stolen from the hack. eXch has denied these allegations, asserting that all its funds are secure and operations remain unaffected. The platform has also criticized Bybit for allegedly damaging its reputation. Security experts have raised concerns about the implications of eXch's involvement, urging other exchanges to enhance their risk management protocols regarding funds linked to eXch. The situation is compounded by a spike in eXch's Ethereum reserves, which has drawn scrutiny following the Bybit hack. As the fallout continues, the cryptocurrency community is closely monitoring the developments surrounding both exchanges.
