- The attack exploited discrepancies in Liminal’s multisig wallet interface.

In one of the most significant cyberattacks of the year, WazirX, an Indian cryptocurrency exchange, lost over $230 million from a multisig wallet. The attack targeted a wallet that used Liminal’s digital asset custody and wallet infrastructure since February 2023.
The wallet had six signatories: one from Liminal and five from WazirX, ensuring secure transactions through required multiple approvals. However, the breach occurred due to discrepancies between the data displayed on Liminal’s interface and the actual transaction contents. During the attack, the payload was replaced, allowing the hacker to gain control of the multisig wallet and steal funds.
Despite using security measures like the Gnosis Safe multisig smart contract platform and a whitelisting policy, the attack exploited these defenses. The Liminal Custody team confirmed that their platform was not breached and that its assets, wallets, and infrastructure remain safe.
India’s regulatory landscape for crypto remains underdeveloped, with no specific guidelines for security measures, risk management, and consumer protection. Joanna Cheng, associate general counsel at Fireblocks, highlighted the need for clear regulatory frameworks to hold exchanges accountable.
Following the attack, WazirX outlined the details of the breach in a post on X, assuring stakeholders that efforts are ongoing to retrieve the stolen assets. Describing the attack as a “force majeure event,” WazirX explained that despite taking “all necessary steps to protect customer assets,” the theft still occurred. They are currently working with cybersecurity teams to locate and recover the funds and have promised to keep the community updated.
