Harmony (ONE) Offers $1M Bounty for Return of Stolen Funds

Concord Protocol, which misplaced $100 million in a bridge assault earlier this week, has introduced a $1 million bounty for returning stolen funds and a proof for the breach.

As well as, the corporate, which makes a speciality of cross-chain bridges, introduced that it could foyer for no prison costs after the cash is returned.

It equipped an electronic mail ([email protected]) and an Ethereum pockets (0xd6ddd996b2d5b7db22306654fd548ba2a58693ac) tackle for the attacker to get in contact.

It stays to be seen whether or not the hacker will settle for the bounty, which is only one% of the stolen funds. They maintain $98 million of the stolen funds in an Ethereum pockets and about $1.79 million at a Binance Sensible Chain tackle.

Concord first reached out to the hacker on June 24, indicating that they had been excited about negotiations, even when executed anonymously.

Concord exploit used compromised personal keys

Concord, a proof-of-stake blockchain, misplaced $100 million after hackers focused the Horizon bridge used for transferring tokens between the Ethereum community and the Binance Sensible Chain. The exploit used compromised personal keys, in keeping with safety agency Peckshield.

Non-public data from two of 4 crypto wallets supporting the bridge was used to siphon $100 million in ether, Binance Coin, and three stablecoins, to an exterior pockets. In line with forensics agency Elliptic, these had been swapped for ether utilizing a decentralized alternate.

A Twitter person going by the pseudonym @_apedev identified the vulnerability to Concord in April.

Cross-chain bridge vulnerabilities

Blockchains have native tokens incompatible with different blockchains. For instance, ether can solely be used on the Ethereum blockchain, whereas bitcoin can be utilized on the Bitcoin community. Cross-chain bridges allow exchanges of tokens between totally different blockchains. Nevertheless, they’re advanced, with software program typically developed by an nameless group.

To make use of your forex of alternative on the Bitcoin community includes utilizing a bridge to transform your token to “wrapped bitcoin,” an alternate retailer of worth on the goal community just like a voucher. Sensible contracts deal with the conversion.

The wrapped bitcoin is underwritten by precise bitcoins on the bridge, which grow to be a goal for hackers since it’s typically unclear how the funds on the bridge are protected.

Bridges weren’t wanted within the early days of crypto circa 2009, because the Bitcoin community was the one blockchain. Quick ahead 13 years later, and you’ve got the explosion of decentralized finance demanding the chasm between blockchains be bridged.

To this point, one of many largest bridge hacks noticed over $600 million stolen from the Ronin bridge utilized by Sky Mavis for his or her play-to-earn sport Axie Infinity in March. This hack, which resulted from a personal key compromise, took the whole loss from bridge hacks to $1 billion.

Concord’s ONE token fell to a seven-day low on June 24, buying and selling at $0.0236. It recovered barely to $0.0244 at press time, in keeping with Coingecko.
