Harmony Bridge · 2022-06
In June 2022, Harmony’s Horizon Bridge lost about $100 million in virtual currency after attackers compromised bridge-validator private keys and moved assets including USDC, ETH, USDT, BNB, and other tokens through wallet hopping and Tornado Cash. Harmony described the event as a coordinated attack on internal infrastructure rather than a smart-contract exploit, and the FBI later attributed the theft to Lazarus Group/APT38.

Harmony · 2022-06-24
Description of the event: Harmony Horizon bridge was hacked. According to the analysis of SlowMist MistTrack, the attackers made more than 100 million US dollars, including 11 ERC20 tokens, 13,100 ETH, 5,000 BNB and 640,000 BUSD. On the 26th, Harmony founder Stephen Tse said on Twitter that Horizon was attacked not because of a smart contract vulnerability, but because of a private key leak. Although Harmony stored the private keys encrypted, the attacker decrypted some of them and signed some unauthorized transactions. At present, Harmony has migrated Horizon's verification authority on the Ethereum side to 4/5 multi-signature. It is reported that this incident is suspected to be related to the North Korean hacker group Lazarus Group. | Amount of loss: $ 100,000,000 | Reference: https://twitter.com/harmonyprotocol/status/1540110924400324608

Para 148: “According to numerous sources, the Horizon Bridge for the Harmony blockchain, which bridges Bitcoin, the ETH network and the Binance Chain, was compromised by a very similar cyberattack on 23 June 2022, in which multiple transactions were made to steal various types of Altcoins. ... The stolen assets were sent to different wallets in the Uniswap decentralized exchange for “coin swapping” into an assessed 85,800 ETH. ... On 29 June, based on the strong resemblance to previous cryptohacks by the group, including the Ronin hack, a blockchain analysis firm identified the Lazarus Group as the prime suspect. Investigations are ongoing.”

Para 165: “The hack of Harmony’s Horizon Bridge (June 2022) has been attributed to the Lazarus Group because of the methodologies used, which closely resemble those used in Axie Infinity’s Ronin network hack (March 2022). According to numerous sources, including several cybersecurity firms, on 13 January 2023 this group moved about half of the assets stolen in the Horizon Bridge hack, valued at $63.4 million in Ethereum [footnote 147: 41,000 ETH]. Railgun was used to deposit the funds in three different cryptocurrency exchanges. ... The exchanges involved blocked the transfers and froze the accounts, recovering 124 bitcoin in the process valued at $2.6 million at the time.”
