On Thursday, June 23, 2022, the Harmony Protocol team was notified of a malicious attack on our proprietary Horizon Ethereum Bridge. At 5:30 AM PST, multiple transactions occurred that compromised the bridge with 11 transactions that extracted tokens stored in the bridge. The estimated value at the time of the attack was approximately $100 million USD.

Immediately following the attack, multiple cyber security partners, exchange partners, and the FBI were notified and requested to assist with an investigation in identifying the culprit and methods to retrieve stolen assets. With those contacts established, Harmony announced the hack via Twitter (link below) with a description of what occurred and our next steps.

Further, the team has attempted communication with the hacker with an embedded message in a transaction to the culprit’s address (above) at approximately 5:30 PM PST.

A complete breakdown will be provided at the conclusion of this investigation.

Harmony believes that focusing on decentralized bridges is an essential step forward for Web3. This incident is a humbling and unfortunate reminder of how our work is paramount to the future of this space, and how much of our work remains ahead of us.

Ongoing investigations present a challenge of what information is allowed to be shared with the public, but we will continue to provide updates with the latest information as soon as we are able to share.

This article will be regularly updated with the latest information, and will be provided via our Twitter and other social platforms. The goal is to continue providing regular updates throughout this process to keep everyone informed.

We are working around the clock to ensure both the investigation and recovery of stolen funds are concluded in the most time efficient manner possible.

  2. Stupid banks, so easy to rob, zero points to trust them. Crypto is our future!

    Oh, wait

  3. If what people are saying that all the hacker had to do was corrupt two signatures to steal 100 Mio!! and that weakness had been pointed out to the Team responsible, cant help but feel this is gross negligence in their Part.

    Honestly i really cant wait to See some severe Regulation to ensure people take responsibility and dont just shrug Off such gaping holes in the security of the funds they Store.

    To be fair i obviously lack the understanding to judge if the links provided in reddit are true or not but if they are i really want to See a statement fast.

  4. Can someone tell me what happens to those holding those coins on the other side of the bridge (Ie the 1usdc, 1btc etc)

    Are they unable to convert back? Are specific coins locked up or does everyone have to share in the remaining pool in the bridge so it becomes a race? Does the value depeg?

  5. BRO THE PRICE ON SUSHISWAP IS 0.09 CENT….ITS SHOULD BE 0.03 if I sell my nft I get husstled
