- Here is what we know so far about the Liquid hack.
Liquid hack: what happened?
On August 19, Liquid, the Japanese crypto-fiat exchange platform announced on its Twitter account1 it suffered a hack and lost over $90 million in BTC, TRX, XRP, ETH, and ERC-20 tokens. According to the announcement, the exchange’s hot wallets were compromised and the Liquid team proceeded to move funds to cold storage.
The exchange also reported several crypto addresses linked to the hack and said it was investigating the funds’ movements. During the investigation process, deposits and withdrawals have been halted on the exchange platform.
The Japanese exchange worked with other crypto platforms to freeze and recover the funds. Kucoin’s CEO announced the exchange has blacklisted the hacker addresses2. Kucoin also suffered a hack in late 2020.
This hack just followed the massive Poly Network hack that took place earlier this month, siphoning more than $600 million; the largest DeFi hack to date. However, all the funds have been sent back to Poly Network. (Read more: Poly Network hack: the largest DeFi hack to date. How to monitor the funds?).
Analysis of the Liquid hack-related addresses
The first batch of addresses initially reported by Liquid included the following 4 crypto addresses:
- BTC: 1Fx1bhbCwp5LU2gHxfRNiSHi1QSHwZLf7q (received 107 BTC);
- ETH: 0x5578840aae68682a9779623fa9e8714802b59946 (received around $60 million in ETH and ERC-20);
- XRP: rfapBqj7rUkGju7oHTwBwhEyXgwkEM4yby (received more than 11 million XRP)
- TRX: TSpcue3bDfZNTP1CutrRrDxRPeEvWhuXbp
What’s interesting is that the hacker used centralized exchange platforms (CEXs) to deposit some of the stolen funds. The hacker could thus be identified if he/she passed KYC procedures when registering on the platforms.
For example, according to Liquid3, the hacker deposited the stolen XRP to centralized exchanges such as Huobi or Poloniex and then changed it to BTC sent on 2 identified addresses. For now, the funds are still sitting on the addresses:
- 12PKkwoFkXp6JtN7roWRA2gSitE6nVDds4 (92 BTC); and
- 1JW1tcBXp1vZ6KGEirFNSXb5RgZSaL63Av (100 BTC)
The hacker also used a mixing service and sent more than 9,000 ETH from the address 0x5578840aae68682a9779623fa9e8714802b59946 to Tornado Cash mixer. Mixers are used to obfuscate the origin of funds, and once coins reach a mixer, it is very difficult to trace them.
Besides, if we look at another Ethereum address reported by Liquid4 (0xff0f573bdf4c23e41ea3ecd82efa66828706b711), we can see that the hacker is using decentralized exchanges (DEXs) such as Uniswap to swap tokens to ETH as shown below.

Are crypto funds easy to launder?
Crypto funds related to hacks represent higher ML/TF risks. Hackers can use several methods to try to launder stolen crypto, such as mixers or DEXs. However, it’s getting difficult to launder the proceeds of crypto crimes as many countries are implementing crypto AML/CFT regulations.
This shows the importance of having AML/CFT processes and blockchain analytics tools in place. Such tools allow companies operating with cryptocurrencies to monitor funds and identify risks. This is how these companies can ensure they remain compliant with the evolving crypto regulations worldwide.
