Ignoring The Bounty, Penpie Hacker Launders $27 Million In Ether – What’s The Endgame?

by

As a seasoned researcher with over two decades of experience in the realm of cybersecurity and cryptocurrencies, I find the Penpie hack and its aftermath deeply concerning. The swift laundering of $27 million in Ethereum through Tornado Cash highlights the ongoing weaknesses that persist within DeFi platforms, a matter that should not be taken lightly by developers, investors, or regulators.

A cybersecurity expert referred to as Penpie is accused of cleaning $27 million worth of Ethereum using the widely used mixing service Tornado Cash, following a cyberattack on September 4, 2024. This incident underscores some persistent vulnerabilities within Decentralized Finance (DeFi) systems. In reality, the swift transfer of funds by this hacker has raised concerns about the ability to trace stolen assets in the realm of cryptocurrency.

Swift Laundering Raises Concerns

In a matter of mere hours following the hack, the Penpie cybercriminal funneled approximately $7 million via Tornado Cash. Their activity was far from over; in fact, they proceeded to move substantial amounts at regular intervals for several days. By the end of this period, an impressive 11,261 ETH (valued around $26.7 million) had been transferred.

Working so swiftly is indeed astonishing, and given the security measures set up for DeFi protocols, many in the crypto community find it hard to believe such speed.

The firm attempted negotiations with the hacker, proposing a reward and full immunity from legal action if they assisted. Moreover, they suggested employing the hacker as an ethical hacker or ‘white-hat’ security tester, whose role is discovering software weaknesses to report back to the relevant firms.

In spite of the negotiations intended to limit damage and prevent lawsuits, the hacker disregarded the proposal and illicitly transferred the pilfered $27 million using Tornado Cash instead.

As a crypto investor, I’ve come to realize that the risks associated with decentralized platforms are significantly higher due to an increased focus by hackers on exploiting these systems for illicit activities, such as money laundering through privacy tools like Tornado Cash.

In the broader context, the Penpie hack incident involves at least four different hacking groups who have moved over 20,561 Ether (roughly equivalent to $49.3 million) using Tornado Cash since early September.

Penpie Hacker: The Bigger Picture

The impact of these occurrences extends far beyond mere monetary damages, raising significant concerns about the future of Decentralized Finance (DeFi) and the delicate equilibrium between privacy and safety. Tornado Cash, originally intended to grant anonymity to its users, now serves as a two-sided tool.

Essentially, the actions of the Penpie hacker underscore the inadequacy of the current security measures in the DeFi sector, as they cannot effectively prevent or mitigate such cyberattacks. The swift laundering of funds through services like Tornado Cash poses a significant risk to the overall integrity of the cryptocurrency market.

It’s crucial to tackle the gaps we see, and doing so necessitates collaboration among developers, investors, and regulatory bodies to control this escalating issue.

Simultaneously, to demonstrate his pride, the perpetrator behind a $195 million flash loan attack on Euler Finance in March 2023 sent a message on the blockchain to the hacker. He commended his counterpart thief, for not returning the funds, expressing approval by saying:

Excellent work, mate! Your tactic was something fresh I haven’t seen in a while. It’s great to see that you managed to keep all the earnings and not let them recover even a single cent. They lost, you won. Well done!
