WazirX shared with Gadgets360 how the cyber attack happened on Thursday. They said one of their multisig wallets, managed by six signatories (five from WazirX and one from Liminal), was attacked. There was a mismatch between Liminal’s displayed data and the actual transaction, likely allowing the attacker to take control.
Despite using security features like the Gnosis Safe multi-sig platform and Liminal’s allowlisting policy, the incident occurred. WazirX has paused withdrawal and deposit services. Mudit Gupta, Polygon’s chief information security officer, told Gadgets360 there is an “80 percent” chance that North Korean hackers were involved.
The hacker is selling stolen tokens, including $100 million in Shiba Inu and $52 million in Ether, on the decentralized exchange Uniswap. WazirX has shared the affected wallet address: 0x27fD43BABfbe83a81d14665b1a6fB8030A60C9b4.
Blockchain data shows that attackers are trying to sell their assets on the decentralized exchange Uniswap. Risk-management platform Elliptic said the hackers might be linked to North Korea. Lookchain, a third-party blockchain explorer, reported that over 200 cryptocurrencies were stolen from the platform. This included 5.43 billion SHIB, 15,200 Ethereum, 20.5 million Matic, 640 billion Pepe, 5.79 million USDT, and 135 million Gala tokens.
