Approximately US$100 million ($138 million) was stolen from US crypto firm Harmony’s “Horizon bridge”, which allows users to transfer crypto between different blockchains.
Harmony CEO Stephen Tse said the firm discovered evidence that private keys were compromised, leading to the breach of the Horizon bridge. The firm is currently working with national authorities and forensic specialists to identify the culprit and retrieve the stolen funds, on top of offering a US$1 million bounty for the return of the funds as well as sharing of exploit information.
