Harmony Horizon Bridge hack
Harmony's Horizon bridge was exploited for about $100M in June 2022 after attackers compromised multisig signing keys. The FBI later attributed the theft, along with the Ronin hack, to North Korea's Lazarus Group.
Also known as: Harmony, Horizon Bridge
Summary
The Horizon bridge, which connected the Harmony blockchain to Ethereum and other networks, was exploited in June 2022 for about $100 million. Analyses indicate the attackers compromised the private keys controlling a multisignature wallet that secured the bridge. [1][2]
Attribution
In January 2023 the FBI attributed the Harmony theft to the Lazarus Group (also tracked as APT38), the same North Korea-linked actor blamed for the Ronin hack, and described laundering of the proceeds. [2]
