Mobius Token Hacked, $2.15 Million Stolen on BNB Chain

A critical vulnerability in the Mobius Token (MBU) smart contract on BNB Smart Chain has led to a $2.15 million loss, adding to the growing list of crypto-related exploits in 2025. Mobius is a lesser-known project within the BNB ecosystem.

The attack, confirmed by Web3 security firm Cyvers on May 11, involved a malicious hacker who took advantage of a flaw in the MBU minting mechanism. The incident began at 07:31 UTC when a wallet (0xB32A5) deployed a rogue contract. Just two minutes later, another address (0x631adf) initiated a series of suspicious transactions.

Using only 0.001 BNB, the attacker minted 9.73 quadrillion MBU tokens and quickly exchanged them for stablecoins, netting $2.15 million. In the same process, the attacker also gained an additional 28.5 million MBU tokens. After the exploit, the stolen assets were moved to Tornado Cash, a popular protocol that anonymizes transactions. The method and speed of the exploit point to a calculated move to evade tracking and asset recovery. This incident further highlights the persistent vulnerabilities facing smart contract-based systems.

Meanwhile, this Mobius hack makes it the latest victim in a wave of blockchain exploits that have resulted in the loss of around $2 billion across various platforms, including Bybit. Despite isolated incidents like the Mobius breach, BNB Chain is witnessing a significant resurgence in user and developer activity. Over the past months, the network has reemerged as a top contender in the DeFi space.

BNB Chain also recently claimed the top spot in the decentralized exchange (DEX) sector, outpacing both Ethereum and Solana. Market observers noted that the network’s growth is fueled by fresh institutional interest, an increase in DeFi participation, and strong demand for on-chain assets. Moreover, the momentum can also be partly attributed to Binance’s continued influence and Changpeng Zhao’s renewed focus on the blockchain network.

This incident underscores the ongoing challenges in securing smart contracts and the need for robust security measures to protect against such exploits. The rapid response and anonymization of funds through Tornado Cash demonstrate the sophistication of the attack and the need for enhanced monitoring and security protocols within the blockchain ecosystem. As the BNB Chain continues to grow, it will be crucial for developers and users to remain vigilant against potential vulnerabilities and to implement best practices for securing smart contracts and digital assets.
