The United States Treasury Department is stepping up attempts to halt the flow of stolen cryptocurrency following an unprecedented $620 million hack.
A serving military captain and the operator of a cryptocurrency exchange were recently arrested in South Korea on suspicion of espionage for a North Korean hacker. The two South Koreans were allegedly paid a total of $637,789 in bitcoins in exchange for their espionage activities.
Three ethereum addresses have been added to the Office of Foreign Asset Control's (OFAC) Specially Designated Nationals and Blocked Persons List (SDN). The Lazarus Outfit, a cybercrime group linked to North Korea, is said to be in charge of the ether addresses, according to OFAC.
The operators of a cryptocurrency wallet that has been sanctioned by the United States continue to sell their cash.
The three new wallets join an Ethereum address that was put to the sanctions list just a few weeks ago.
It has been reported that an Ethereum wallet with more than 100,000 stolen cash has been blocked by US authorities.
The United States Treasury Department has sanctioned an ethereum (ETH) address that it says received coins stolen in the Ronin Validator hack – and the FBI has claimed that the North Korean Lazarus group of hackers was behind the security breach.
