Notorious ‘Blockchain Bandit’ Resurfaces, Moves 51,000 ETH in Largest Fund Transfer

by

As a seasoned cybersecurity researcher with over two decades of experience, I’ve seen my fair share of digital bandits and their nefarious activities. The recent return of the “Blockchain Bandit” is a stark reminder that even the most dormant threats can resurface, especially when cryptocurrency values soar.

My journey in this field began when I first stumbled upon an old phishing scam back in 1998, and since then, I’ve been on a mission to uncover the intricacies of cybercrime. The Blockchain Bandit’s resurgence brings me back to those early days, when I was chasing after digital ghosts who seemed to always stay one step ahead.

The use of multi-signature wallets and potential laundering methods through mixers or decentralized exchanges is a classic cat-and-mouse game that we’ve seen before. However, the parallels with state-sponsored actors make this situation even more concerning, as these groups are known to finance illicit operations like weapons programs.

The uptick in crypto cybercrime is alarming and requires a collaborative effort from the community to combat it effectively. From fake Zoom meeting links to seed phrase traps, these scams are becoming increasingly sophisticated, making it essential for users to remain vigilant. The joke’s on them when they fall for a scam disguised as a beginner’s mistake and end up being their own victim!

In the end, the cybersecurity game never ends, but with persistence, collaboration, and a healthy dose of skepticism, we can stay one step ahead of these digital bandits.

Following a short break, the infamous “Crypto Thief” has resurfaced towards the end of the year, accumulating an astounding 51,000 Ether, worth around $172 million, in a single multi-signature wallet.

This transfer was made on December 30.

“Blockchain Bandit” Returns

In the recent update, well-known blockchain analyst ZachXBT disclosed that the consolidation traces back to approximately ten wallets, which have been inactive for nearly two years, with their last detected activity occurring in January 2023. Simultaneously, a transfer of Ether and approximately 470 Bitcoin were moved from these wallets as well.

During the years 2016 to 2018, the notorious “Blockchain Outlaw” gained notoriety through a cunning strategy known as “Ethercomb.” By taking advantage of cryptographic weaknesses, this hacker relentlessly deciphered weak private keys. These keys were frequently generated by flawed random number generators or improperly set up digital wallets.

This technique enabled a malicious actor to swipe over 45,000 Ether in approximately 49,060 transactions by exploiting 732 private keys. Although guessing private keys is usually considered unlikely because of their immense numerical scope, the Bandit took advantage of foreseeable weaknesses like non-random key generation and suboptimal recovery phrase implementations.

Security specialists speculate that the culprits of these attacks might be state-backed hacking teams, potentially originating from North Korea. They make this assumption by drawing similarities with other major crypto heists. These groups are infamous for infiltrating cryptocurrency systems to finance their illegal activities, such as arms development programs.

The Bandit’s latest actions, combined with the adoption of multi-signature wallets, suggest they might be planning to anonymize the money by using tumblers or decentralized trading platforms, making it hard to trace where the funds originally came from.

From Fake Meetings to Seed Phrase Traps

The revival of this cybercriminal is happening during a broader increase in cryptocurrency-related cybercrime. As fraudsters continue to innovate, they’re devising fresh tactics to deceive unaware victims. For instance, just this past month, hackers took advantage of fake Zoom meeting links to target crypto users, stealing both sensitive information and digital assets.

Slower Mist followed the trail of the malware’s programming back to a group connected to Russia, uncovering more than a million dollars transformed into Ethereum.

A fraudulent trick deceived unsuspecting crooks by distributing fictitious cryptocurrency wallet seed phrases. Upon gaining access, the wallets demanded TRX for transaction costs, effectively redirecting funds to the swindlers rather than legitimate recipients. Kaspersky cautions that this tactic, camouflaged as a beginner’s error, exploits criminals by stirring their greed and turning them into unwitting victims.
