Key Findings from Popular Crypto News
There’s now a widely reported targeted phishing campaign targeting a specific Bitcoin address associated with the Mt. This particular address is home to a huge pile of Bitcoin, and it hasn’t moved a dime in more than 10 years. Scammers consider it a low hanging fruit. The phishing campaign masquerades with a fancy scam email. Its goal is to dupe the owner into disclosing confidential data, which would allow the attacker to steal the owner’s money. This unfortunate event serves as a reminder of the persistent dangers of possessing cryptocurrency, especially in wallets that have been inactive for years. Finally, it serves as a potent reminder of the need for strong security standards and an ever-watchful eye for threats.
The Scam Targeting Mt. Gox Bitcoin Wallet
As such, a new targeted phishing campaign has begun. In detail, it mainly focuses on a well-known historic Bitcoin address that contains 79,956 BTC (approximately $8.7 billion). The targeted address, 1FeexV6bAHb8ybZjqQMjJrcCrHGW9sb6uF, hasn’t gone anywhere in over 10 years, yet continues to draw bad guys. The phishing attempt includes a very creative scam message. It even directs the unwitting owner to a website that duplicitously pretends to be related to Saloman Brothers, a former Wall Street investment bank that went bankrupt.
The hack has been associated with the Mt. Gox exchange, former one of the largest crypto bankruptcies in history. Law enforcement has recaptured just over 140,000 BTC. Nearly all of the stolen coins continue to languish in inactive wallets, unused for more than 10 years. The rehabilitation plan, which was confirmed in 2021, would allow creditors to recover as much as 90 percent of their lost money. The fact that dormant addresses are still an open invitation to bad actors.
How OP_RETURN is Facilitating Scams
Another scam running rampant now is a fake Mt. Gox Bitcoin wallet. It leverages bitcoin’s op_return message to provide misleading proof of ownership, all tucked away inside a dust transaction. The targeted wallet’s last received “dusting” was dated July 5, 2025. Since then, it has received further tracing transactions/messages. The con email looks a lot like previous efforts by Calvin Ayre to establish ownership of legacy wallets. Ayre’s efforts to take control of legacy wallets have been dubious at best, potentially even malicious. Moreover, as op_return messages have been used to assert ownership of wallets, the authenticity of those claims has come into question.
OP_RETURN is a Bitcoin script opcode which lets users embed arbitrary data into a Bitcoin transaction. This functionality is valuable for many reasons, such as notarizing documents and incorporating metadata. Scammers can easily turn its advantages to their own benefit. These same attackers behind the Mt. Gox phishing attack leveraged OP_RETURN messages making it appear that they owned the wallet in question. Their objective was to con the owner into believing their money was in danger. This emphasizes how harmful OP_RETURN messages can be and the importance of being careful when dealing with unknown transactions.
Implications for Investors and the Crypto Community
Beyond the risk it poses to individual investors, the Mt. Gox phishing attack raises serious questions about investor protection and the future of the crypto space. This is a reminder that even addresses that have remained dormant for many years can become targets for malicious actors. Phishing scams No one is immune to phishing scams! On one hand, the attack highlights the security of crypto holdings and the importance of strong security infrastructure.
Here are some actionable steps to protect your cryptocurrency wallets from similar scams:

- Enable multi-factor authentication: Multi-factor authentication adds an extra layer of security to your accounts, requiring you to provide multiple forms of verification before accessing your funds.
- Verify information: Always verify the legitimacy of any website or message before interacting with it. Be wary of suspicious links and never enter your private keys or other sensitive information on an unfamiliar website.
- Avoid interaction with suspicious links: Do not click on links from unknown sources.
- Stay informed: Keep up-to-date on the latest scams and security threats in the cryptocurrency world.
Taking these three simple steps will go a long way in protecting yourself. By following these simple steps, you can significantly lower your likelihood of becoming a phishing scam or cybercrime statistic.
Legal Controversies Surrounding Calvin Ayre
The continuing saga of Mt. Gox and criminal mastermind Calvin Ayre reminds us that even old, inactive cryptocurrency addresses are vulnerable. Scammers have recently been exploiting Mt. Gox legacy wallets to seduce clueless crypto investors. Only a few months ago, they sent their first incantational op_return message to a whale wallet that had already been drained. This innovative phishing effort is sophisticated and ambitious in its design and intent, attempting to dupe the owner into disclosing sensitive information. A fake website was set up as part of the phishing attempt, but that has since been removed.
Background on Calvin Ayre’s Legal Issues
Calvin Ayre, the founder of the online gambling company Bodog has been in legal hot water for quite some time. In 2012, the U.S. Attorney’s Office for the District of Maryland finally indicted him. …unlawful gambling and money laundering on a grand scale… He was convicted on these felony charges. In 2017, those charges were dropped against Ayre. His guilty plea to a misdemeanor charge of accessory after the fact had already settled everything except the punishment.
Ayre has made headlines for recent battles over the ownership of Bitcoin wallets. These wallets are largely associated with the early days of cryptocurrency. His hacks to take ownership of these wallets have been regarded as suspicious and bad faith. The Mt. Gox phishing attack adds another level of intrigue, leading to speculation that Ayre was actually behind the phishing scam.
The OP_RETURN Ownership Debate and Its Impact
OP_RETURN messages enable you to encode data directly into Bitcoin transactions. Unfortunately, these do not provide conclusive evidence of ownership. Anyone can create an OP_RETURN message claiming ownership of a wallet, regardless of whether they actually own the private keys.
Due to the widespread lack of understanding about OP_RETURN, it has provided fertile ground for scammers and malicious actors alike to take advantage of this feature. The Mt. Gox phishing attack is an example of just how malicious these OP_RETURN messages can be. It serves as a powerful example of how scammers exploit, trick, and coerce innocent cryptocurrency investors. Be wary about drawing conclusions based on OP_RETURN messages. Don’t assume that it’s their job just because they’re there.
