Lazarus Moves More than $60 Million from Harmony Bridge Hack


North Korean state-owned threat actors Lazarus Group has stolen around 41,000 ETH or more than $60 million of Ethereum to the crypto exchanges Binance, Huobi and OKX. While Binance and Huobi both froze the funds, Binance declared that an asset of 124 BTC was also recovered in the process. 

According to internet sleuth ZachXBT, the funds were stolen from the Harmony blockchain bridge hack from last year, which led to a whopping $100 million crypto compromise. Apparently, the same hacker group utilized Tornado Cash, a now banned crypto mixer that conceals names of people involved in the transaction, in order to carry out the attack. 

As per the analysis, conducted by token movements, the ETH was routed through the anonymity system Railgun before being collected in wallets and sent to three significant crypto exchanges, possibly to be exchanged for fiat currency. 

“A very busy weekend” for Lazarus Group 

ZachXBT shared details of this week’s token movements on Twitter, claiming Lazarus Group has had “a very busy weekend” moving funds. 

In the follow-tweets, ZachXBT also linked to the website Chainabuse.com where he shared a list of approximately 350,000 unique wallet addresses that were involved in the Friday’s operation. 

Binance’s Say on the Issue 

On Monday, Binanace CEO Changpeng Zhao, better known as CZ too, commented on the situation. CZ claims that the hackers used Huobi, a competing exchange, rather than Binance this time as one of their exchanges. The hacker's accounts were subsequently frozen with Binance's assistance, he says. 

CZ also disclosed that 124 BTC ($2.6m) had been seized from the hackers, indicating at least some of their ETH has been converted to BTC. 

“We detected Harmony One hacker fund movement. They previously tried to launder through Binance and we froze his accounts. This time he used Huobi. We assisted Huobi team to freeze his accounts. Together, 124 BTC have been recovered,” he wrote. 

Although, Huobi did not comment on the matter other than retweeting an article claiming that the exchange had frozen accounts containing money connected to the hack. 

According to a report from South Korea's National Intelligence Service from December of last year, North Korean hackers have stolen more than $1 billion in digital assets since 2017. 

Moreover, the report claims that around $626 million, or more than half of that estimated tally, was taken in 2022. It also stated that it is suspected that the North Korean government uses the money obtained from the theft to advance Pyongyang’s nuclear weapons program.
