This hack was so simple that the hackers didn’t need to know the Merkle trees and solidity. They had to simply replace the existing transaction with their address and rebroadcast it to the blockchain. In the recent routine update, the Nomad Protocol Developers had made the zero hash a valid root, which enabled hackers to spoof messages and rebroadcast duplicate transactions with their addresses. 

How Did The Attack Take Place?

@samczun, a crypto researcher at Paradigm(A crypto investment firm) has tweeted the complete details about the attack. He went on to illustrate how easy it is for users to impersonate transactions in Nomad Smart contracts. A lot of users were easily able to withdraw the funds from the smart contract that they didn’t own. 

Different tokens were removed from the bridge, such as 100 Wrapped BTC worth approximately 2 Million USD. The complete list of tokens removed from the bridge is Wrapped Ether, USDC, CARDS(card Starter), HBOT( Hummingbird Governance Token), IAGON, FRAX, and much more. 

This was quite different from all the other bridge hacks that have happened recently. The exploiters have used an uncommon way to hack this bridge and made over 200 transactions for 202,440.725413 USD.

According to the defi source DefiLama, the total Value Locked has increased to USD 5,336 following the compromising of around 200 Million in money.

They aim to trace all the accounts used for stealing the funds. Nomad has further highlighted how impersonators provided the fraudulent address to steal funds.

For example, a liquidity pool recently, Crema finance, faced a loss of approximately USD 9 Million. After intense negotiations, the hacker returned the funds in return for a USD 1.6 Million Bounty. 

Also, Qubit FInance was compromised with a hack of 80 USD Million soon after hackers stole 320 Million USD from the Solana-Ethereum Bridge (Wormhole).

Recently in March 2022, approximately 700 Million USD worth of tokens ( USDC and Ethereum) were compromised from the Ronin Bridge
