On February 24, crypto data analysis company Bitrace issued a warning that after Bybit was hit by $1.5 billion hacker attack, a large-scale freeze targeting OTC groups and crypto payment companies will soon appear in the next few months. Bitrace research shows that in addition to using unlicensed industry infrastructure to clean up funds, the hacker organization will also use a large number of centralized platforms for dumping, which directly leads to a large number of exchange user accounts that intentionally or unintentionally collect stolen money and are risk-controlled. The business addresses of merchants and payment institutions were frozen by TEDA. After the Japanese DMM exchange was hacked in 2024, the attacker transferred $600 million to payment agency HuionePay, causing $29 million in its hot wallet to be frozen. In 2023, Poloniex suffered losses of more than $100 million, and hackers cleaned funds through over-the-counter transactions led to a large number of OTC merchants' business blockage.
