Hackers that targeted crypto wallet Atomic Wallet in a $35 million heist earlier this month have used cross-chain liquidity protocol THORChain to conceal their ill-gotten gains, according to blockchain sleuth MistTrack.

MistTrack states that 503.08 ether (ETH), or around $870,000, connected to the hack was transferred to THORChain in the last two days before being swapped for bitcoin (BTC).

Some of the stolen ether was also bridged to multiple bitcoin addresses using the Swft blockchain, MistTrack said.

Last week, the hackers moved a portion of stolen funds to crypto exchange Garantex, which was sanctioned by the Office of Foreign Assets Control (OFAC) of the U.S. Treasury last April.

Blockchain security firm Elliptic said that it believes North Korean hacking group Lazarus are behind the attack.

THORChain's native token (RUNE) remains stable following the string of hack-related transactions, it trades at 84 cents having risen slightly in the past 24-hours, according to CoinMarketCap.
