On Jun. 24, the Harmony team detected the exploit, reporting $100 million in funds compromised. The hack highlighted concerns previously brought up by community members around some of the mutisigs securing the Horizon bridge.
On Jun. 30, the Lazarus Group, an infamous North Korean hacking organization was identified as a suspect behind the $100 million Harmony hack. Blockchain analysis firm Elliptic noted that the manner in which the hack was conducted was similar to other Lazarus Group attacks.
The Horizon bridge hack is one of the largest exploits and hacks in 2022. Analysts believe that the Lazarus Group targeted the employee login credentials to breach Harmony’s security system. The hackers then deployed laundering programs to move the stolen assets.
