A critical vulnerability in the Mobius Token (MBU) smart contract on the BNB Smart Chain led to a loss of $2.15 million, adding to the list of cryptocurrency attacks in 2025. Mobius is a lesser-known project in the BNB ecosystem.
The attack, confirmed by the Web3 security firm Cyvers on May 11, was carried out by a malicious actor who exploited a flaw in the MBU token issuance mechanism.
The malicious actor Mobius redirects funds through Tornado Cash
According to Cyvers, the incident began at 07:31 UTC when the wallet (0xB32A5) deployed a malicious contract. Two minutes later, another address (0x631adf) initiated a series of suspicious transactions.
By using only 0.001 BNB, the attacker issued 9.73 quadrillion MBU tokens and quickly exchanged them for stablecoins, obtaining $2.15 million. In the same process, the attacker also acquired an additional 28.5 million MBU tokens.
After the attack, the stolen assets were transferred to Tornado Cash, a popular protocol that anonymizes transactions. The method and speed of the attack indicate a carefully planned move aimed at avoiding tracking and recovering assets. This incident highlights the ongoing vulnerabilities of systems based on smart contracts.
At the same time, the hacker attack on Mobius makes it the latest victim of a wave of attacks on blockchains that have resulted in the loss of approximately $2 billion across various platforms, including Bybit.

Despite some incidents, such as the Mobius hack, the BNB Chain network is experiencing a significant revival in user and developer activity. In recent months, the network has once again become one of the leaders in the decentralized finance (DeFi) space.
According to DefiLlama, the total value locked (TVL) in the BNB Chain network has exceeded $10 billion, reaching a three-year high. However, this is still significantly below the all-time high of over $40 billion in 2021. BNB Chain also recently took first place in the decentralized exchange (DEX) sector, surpassing Ethereum and Solana.
Market analysts note that the growth of the network is driven by renewed interest from institutional investors, increased participation in DeFi, and high demand for blockchain assets.
Furthermore, this momentum is partly explained by the sustained influence of Binance and the renewed attention of Changpeng Zhao, the founder of Binance, to the development of the blockchain network.#BinanceSquare #Write2Earn #Binance #crypto #trading $ETH
