”We are aware of the incident involving the Nomad token bridge. We are currently investigating and will provide updates when we have them”

”We’re aware of impersonators posing as Nomad and providing fraudulent addresses to collect funds. We aren’t yet providing instructions to return bridge funds. Disregard comms from all channels other than Nomad’s official channel”

The Details of the Nomad Hack

The first illicit transaction is suspected of occurring at 9:32 UTC, Monday. It all started with a suspicious transaction removing 100 wrapped Bitcoin (WBTC) worth $2.3 million from the bridge. However, the incident has seen a number of tokens exploited from the bridge. This includes the likes of Wrapped Ether (WETH), Covalent Query Token (CQT), USD Coin (USDC), Frax (FRAX), IAGON (IAG), Hummingbird Governance Token (HBOT), Card Starter (CARDS), GeroWallet (GERO), Dai (DAI), and others.

Interestingly, this exploit has been quite different from other bridge exploits occurring in 2022. During the hacking event, hundreds of addresses received tokens directly from the bridge.

Furthermore, exploiters removed all of these tokens in an unusual pattern. They removed tokens from the bridge in equivalent denominations. The attackers executed over 200 transactions each with exactly 202,440.725413 USD.

Vitalik Buterin’s take on cross-chain Bridge?

Bridge exploits have been a very common form of exploit over the last years. Millions of dollars of investors’ funds have been lost in this. In the past, Ethereum co-founder Vitalik Buterin has expressed concern over the use of bridges for cross-chain transfer of funds.

THORChain suffered multiple exploits, and Poly Network was hit by the largest DeFi hack on record worth US$600 million (although the funds were eventually returned).

Vitalik emphasized the fundamental security limits of bridges and argues that blockchains can “maintain many of their guarantees even after a 51% attack,” contradicting popular perceptions that “everything breaks” for a network in the event of a successful 51% attack.
