According to Zhao, exchanges have reclaimed a total of 121 BTC, which is estimated to be worth around $2.5 million at the time of this writing.
Assets consolidated
In a recent post, on-chain crypto detective ZachXBT highlighted that the hackers behind the exploit moved 41,000 Ethereum (ETH) worth about $64 million last weekend, before Binance and Huobi froze and identified the funds.

According to the crypto detective, after the hackers moved the funds, they consolidated the digital assets and deposited them in three different crypto exchanges. However, the on-chain detective did not specify the names of the exchanges used by the exploiters.
Harmony team detected
On June 24, the Harmony team identified the exploit and reported that $100 million in funds had been compromised. Hack highlighted concerns previously expressed by community members about some mutisigers securing the Horizon bridge.
On June 30, Lazarus Group, a notorious North Korean hacking organization, was identified as the suspect behind the $100 million Harmony attack. Blockchain analytics firm Elliptic stated that the way the attack was carried out is similar to other Lazarus Group attacks.
Horizon bridge hack is one of the biggest exploits and hacks in 2022. Analysts believe Lazarus Group targeted employee login credentials to breach Harmony’s security system. The hackers then used laundering programs to move the stolen assets.
Harmony’s Horizon Bridge scammed $100M
The Horizon Bridge to the Harmony Layer-1 blockchain was exploited for $100 million in altcoins exchanged for Ether. The hack may justify previously raised community concerns about the robustness of two of the four multisigs reportedly protecting the bridge.
11 transactions were made through the bridge for various tokens. Since then, they have started sending tokens to a different wallet to exchange for ETH on the Uniswap decentralized exchange (DEX) and then sending ETH back to the original wallet.
As we mentioned as Kriptokoin.com, the Horizon bridge facilitates token transfers between Harmony and the Ethereum network, Binance Chain and Bitcoin. He said the BTC bridge and assets were not affected by the attack. The Harmony team also said it was working with “national authorities and forensic experts” to determine who was responsible.
