Hackers Target Mt. Gox Victim After Reimbursement: Here is How to Stay Safe

Victims of the long-defunct Mt. Gox exchange are facing new threats even as they await long-promised repayments. Cybercriminals are reportedly targeting old Bitcoin addresses linked to the infamous hack, attempting to trick owners into revealing sensitive information. 

This renewed wave of scams underscores the persistent risks in the cryptocurrency world and highlights the need for careful security practices, particularly for those receiving reimbursements from the Mt. Gox bankruptcy process.

A New Twist in the Mt. Gox Saga

More than a decade has passed since Mt. Gox collapsed following devastating hacks that drained 850,000 Bitcoin, a sum now worth over $92 billion. 

While creditors have fought for years to recover even a portion of their losses, scammers are exploiting this long-running saga in new ways.

According to research by BitMEX, hackers have targeted an old Bitcoin address known for holding around 80,000 BTC stolen from Mt. Gox. This address, famous in the crypto community, now appears to be the focus of a sophisticated phishing attempt. 

Attackers sent a small transaction with an OP_RETURN message, which allows text to be stored on the blockchain. This message contained a website link designed to lure the wallet owner into visiting the page.

How the Scam Works

The tactic is simple but effective. The OP_RETURN message includes a web address claiming the wallet is "lost or abandoned" and suggests the visitor might reclaim it. 

The linked site purports to represent Saloman Brothers, an old Wall Street firm that has long been closed, making the claim immediately suspect.

BitMEX Research described the site as illegitimate and warned that it is part of an "ongoing Bitcoin scam" seeking personal information from unsuspecting victims. 

Researchers also noted that other Bitcoin addresses dating back to 2011 have received similar phishing messages, suggesting that this is a broader, coordinated effort by scammers to exploit early Bitcoin users.

The Background on Mt. Gox Repayments

The collapse of Mt. Gox remains one of the most significant events in Bitcoin’s history. Once the world’s largest Bitcoin exchange, the Japanese platform went bankrupt in 2014 after multiple hacks. 

The company lost a total of 850,000 BTC, sparking years of legal battles and a lengthy rehabilitation process.

In 2021, a proposal was approved to reimburse creditors with around 90% of the assets owed to them. Law enforcement efforts managed to recover about 140,000 Bitcoin, which are now being distributed to creditors. 

These repayments have drawn renewed attention to old Bitcoin addresses associated with Mt. Gox, making them prime targets for fraudsters looking to exploit unsuspecting claimants.

Why These Attacks Matter

These scams highlight the evolving tactics of cybercriminals. Even after years of inactivity, addresses linked to high-profile hacks attract attention not just from blockchain analysts but also from hackers hoping to find owners who might let down their guard.

With billions of dollars at stake, phishing campaigns using blockchain messaging features such as OP_RETURN can be a powerful lure. 

The ability to embed text directly in the blockchain makes it difficult to block such messages entirely, leaving wallet owners responsible for recognizing and avoiding these schemes.
