Wallets linked to the notorious “Blockchain Bandit” have resurfaced after years of dormancy, moving a staggering 51,000 ETH ($172M) into a secure multi-signature wallet.
-
The recent transfer from 10 inactive wallets, last utilized in 2018, marks a significant re-emergence of an infamous figure in cryptocurrency theft.

Experts warn that this consolidation could be a precursor to laundering efforts or planning new crypto exploits, raising alarm across the crypto community.
Recent activity from the “Blockchain Bandit” raises concerns about possible liquidation or funding of new exploits in the crypto space as they move $172 million in ETH.
Who Is the Blockchain Bandit Hacker?
The term “Blockchain Bandit” refers to a hacker who leveraged weaknesses in private key security on the Ethereum blockchain to steal substantial amounts of cryptocurrency. Recent analysis by crypto investigator ZachXBT revealed that all wallets involved in the transfer today were dormant since 2018, suggesting a potentially alarming intent behind this sudden activity.
The Blockchain Bandit made headlines for methodically targeting Ethereum wallets with poorly generated or weak private keys. Using automated scripts, the hacker scanned the blockchain for vulnerable addresses and executed thefts without alerting the victims until days later. Across more than 10,000 wallets, this individual is believed to have stolen over 50,000 ETH.
This attack method drew significant attention, particularly from security analysts like Adrian Bednarek, who documented how the Blockchain Bandit employed a pre-generated list of keys to automate scanning vulnerable wallets. As Bednarek suggested, some wallets were using incredibly simple keys, which made them easy targets.
“You see, on Ethereum, private keys are 256-bit numbers. Brute-forcing one is basically impossible. But some wallets were using terrible random number generators, creating weak private keys. His approach made him nearly unstoppable,” noted Web3 analyst Pix.
Why Is the Attacker Active Again After Five Years?
The reactivation of these wallets signifies a strategic move by the Blockchain Bandit, especially considering this was the first significant transaction since 2018. While some movements occurred in January 2023, today’s transfer to a multi-signature wallet is alarming, as it may indicate plans for either laundering or liquidating these assets.
Moving significant amounts of ETH into a multi-signature wallet often implies preparation for high-stakes transactions. Such activity could suggest that the hacker intends to use decentralized exchanges or mixing services to obscure the origins of the funds, effectively laundering stolen assets.
Alternatively, the consolidation of funds may precede liquidation, sparking concerns about potential impacts on Ethereum’s market price. Large-scale selling could inadvertently affect liquidity and investor sentiment within the cryptocurrency market.
Lastly, there’s the most troubling possibility that this consolidation of funds could enable more malicious activities. This includes funding transaction fees for future exploit attempts or scaling operations on various blockchain platforms.
The prospect of such a notorious hacker becoming active again raises significant concerns for the crypto ecosystem, particularly as 2023 has already seen $2.3 billion lost to cyber-attacks, a notable increase compared to previous years. Ethereum remains particularly vulnerable, being the most targeted network in this recent wave of security breaches.
Conclusion
The re-emergence of the Blockchain Bandit with a significant ETH transfer is a stark reminder of ongoing vulnerabilities in the crypto space. Stakeholders should remain vigilant about potential market impacts and the risk of increased cyber threats as the hacker’s intentions unfold. Monitoring such developments closely can help the cryptocurrency community mitigate risks and secure their assets more effectively.
