Hackers have recently targeted a Bitcoin address holding approximately $8 billion, stolen from the Mt. Gox exchange, through a phishing attempt. The attackers sent a transaction using the OP_RETURN feature, which allows information to be stored on Bitcoin's blockchain, directing the wallet owner to a suspicious website. The URL claims to have taken possession of the wallet and is likely a scam designed to collect personal information. This wallet is notable as it belongs to a batch of Bitcoins where approximately 850,000 BTC were lost due to hacks and mismanagement at Mt. Gox, a once-prominent cryptocurrency exchange. Although a rehabilitation plan was proposed to reimburse affected customers, only a fraction of the total stolen Bitcoin has been recovered. The current phishing scheme seeks to exploit the remnants of this notorious incident by targeting old Bitcoin addresses still holding significant amounts of value.
