Axie Infinity co-founder suffers $9.5M loss in wallet hack

Web3 & Enterprise·February 24, 2024, 7:54 AM

Jeff “Jihoz” Zirlin, one of the co-founders of Sky Mavis, the Singapore-headquartered development firm behind both Axie Infinity and the Ronin Network, has faced a significant setback as some of his personal crypto wallets have fallen victim to a hack.

Funds drained through Tornado Cash

The hack has resulted in the loss of approximately $9.7 million worth of ether (ETH). The breach, which occurred on Feb. 23, saw two crypto wallet addresses associated with Zirlin compromised. The perpetrator managed to abscond with 3,248 ETH, funneling the stolen funds through Tornado Cash, a privacy-focused Ethereum mixer.

 

The alarm was raised by PeckShield, a blockchain investigation firm, which identified the compromise of a "whale wallet" through the Ronin Bridge. PeckShield attributed the breach to a "wallet compromise," which facilitated unauthorized outbound transfers of funds.

 

PeckShield's investigation revealed that the pilfered 3,248 ETH was initially dispersed across three different wallets before being funneled into Tornado Cash. This service, notorious for its use by hackers seeking to obfuscate the origin and traceability of illicit funds, served as a conduit for the stolen assets.

 

Confirming the attack and remarking on having had a “tough morning,” Zirkin outlined on social media that “the attack is limited to my personal accounts, and has nothing to do with validation or operations of the Ronin chain.”

 

He emphasized the implementation of stringent security protocols across all chain-related activities, seeking to reassure stakeholders of the company’s commitment to safeguarding user assets. Although specific details regarding the breach remain undisclosed, Zirlin's statement suggests a leakage of the private keys associated with his personal wallets, granting unauthorized access to the hacker.

 

Ronin Network secure

PeckShield’s revelation prompted Aleksander Larsen, co-founder of Ronin Network, to swiftly respond, affirming the robust security measures of the Ronin Bridge. The social media post that Larsen had responded to, which he claimed to have an “extremely misleading title,” was later deleted.

 

Larsen suspected that the breach stemmed from a wallet hack rather than a flaw within the bridge itself. Notably, Ronin had been targeted in a high-profile attack in March 2022, orchestrated by the North Korea-backed Lazarus Group, resulting in a $625 million loss.

In response to this previous breach Sky Mavis initiated a comprehensive overhaul of Ronin's core systems to bolster decentralization and mitigate future vulnerabilities.

 

$112M Ripple co-founder hack

In a separate incident, Binance intercepted $4.2 million worth of stolen XRP, part of the $112 million hack targeting Ripple co-founder Chris Larsen's personal wallet on Jan. 31. Unlike the Axie Infinity breach, the perpetrator behind Larsen's hack refrained from leveraging crypto mixer services or decentralized exchanges, enabling Binance to track and immobilize a portion of the illicitly obtained funds.

 

Axie Infinity, heralded as a pioneering "play-to-earn" Web3 game, has emerged as a lucrative platform, enabling players to earn cryptocurrency and trade in-game assets via blockchain technology. Since its inception in 2018, the game has amassed $1.3 billion in revenue, underscoring its prominence within the burgeoning blockchain gaming ecosystem.

China Furthers Efforts to Shape the Metaverse

China Furthers Efforts to Shape the MetaverseFindings by US political media outlet POLITICO suggest that Chinese authorities and state-owned companies are seeking to mold the metaverse in line with existing systems in China such as the country’s social credit scoring system.The concept of the metaverse entails a network of interconnected immersive virtual worlds powered by virtual reality, augmented reality, and simulations. Development in this area is centered around applications such as online gaming and virtual events.Photo by Hanson Lu on UnsplashDigital Identity SystemIn a report published on Sunday, POLITICO referenced recently drafted proposals put forward by China Mobile, a state-owned telecoms operator. The proposals outline a “Digital Identity System” for users within online virtual worlds and metaverses.These proposals recommend the use of “natural characteristics” and “social characteristics” within digital IDs, encompassing personal data such as occupation, “identifiable signs,” and other attributes. Moreover, they suggest storing this information “permanently” and sharing it with law enforcement to ensure order and safety within the virtual realm.Setting agreed benchmarks for emerging techThe proposals present a hypothetical scenario involving a disruptive user named Tom, who causes turmoil in the metaverse. The digital identity system, according to these proposals, would facilitate prompt identification and punishment by law enforcement.These discussions are occurring within the framework of the International Telecommunication Union (ITU), a United Nations (UN) agency responsible for establishing global technology standards. This strategy echoes China’s endeavor to set worldwide benchmarks for emerging technologies.The ITU, as a UN agency, holds significant sway in defining global telecommunications and technology infrastructure standards. Given that the US and China have quite different outlooks when it comes to technology governance, particularly the future development of the internet and related technologies, the ITU has become a means through which common ground can be found and differences resolved.Upcoming vote on proposalsChina Mobile’s proposals, presented during the ITU’s metaverse focus group meeting, are poised to be voted on during the next meeting in October in Geneva. The company is the largest mobile operator by subscriber base. Demonstrative of ongoing tensions that exist between the US and China, the company was delisted from the New York Stock Exchange in 2021 following a US executive order.Chinese organizations are reportedly submitting more proposals than their Western counterparts, demonstrating that China is very much taking a lead in metaverse development. It’s evident that there is a clear strategy for China to establish itself in furthering this technology.In May, Alibaba Cloud, a subsidiary of Chinese e-commerce giant Alibaba Group, entered into a partnership with layer one blockchain Avalanche to better enable businesses to deploy metaverses. Around the same time, an administrative body within China’s Henan Province established a $22 million dollar investment fund, focused on financing metaverse-related ventures.Later that month, the city of Zhengzhou announced a set of policy proposals designed to support the growth and development of metaverse companies in the region.Within the Chinese autonomous territory of Hong Kong too, there has been plenty of metaverse-related activity. Metaverse start-up Artifact Labs completed a funding round with a view towards expanding its operations. The city is home to Animoca Brands, a prominent player in metaverse-related development.

Japan Set to Tighten Crypto AML Rules

Japan Set to Tighten Crypto AML RulesJapan is working on tightening anti-money laundering (AML) rules relative to digital assets shortly. That’s according to a report by local media outlet Kyodo News.The stricter enforcement measures will take effect from June 1. The objective is to include the tracing of cryptocurrency asset transactions into the legal framework relative to AML, and in that way, bringing the application of AML in Japan into line with global standards.Photo by Louie Nicolo Nimor on UnsplashTravel ruleIn December of last year, the Financial Action Task Force (FATF), a global money laundering and terrorist financing watchdog based in Paris, France, deemed that the approach taken to crypto-related AML in Japan fell short of international requirements and best practice.Specifically, it’s the FATF’s “travel rule” that the Japanese are about to implement. Otherwise known as FATF Recommendation 16, the travel rule is a set of guidelines devised to prevent both terrorist financing and money laundering.The measure puts an onus on all crypto companies to screen all crypto transactions that exceed the value of $1,000 or a variance of this amount based on implementation by each FATF member state. As an example, in the United States, the FATF travel rule is being implemented with transaction monitoring being applied on transactions to the value of $3,000 and above.Once identified, the crypto firm must record details of the transaction and communicate that information, including both sender and recipient data, to the authorities. That would involve the sender and receiver’s legal names, their account numbers, and addresses. Relevant transaction activity includes exchanges between one or more forms of digital currency and the transfer of virtual assets.G7 alignmentThe move follows a decision taken at a Japanese cabinet meeting on Tuesday, as a direct response to FATFs recommendations. Following discussions earlier this month, the intergovernmental political forum of the G7 group of countries indicated its support for the FATF’s call for the establishment of the travel rule as a global standard. Japan is currently leading the group through its G7 presidency and likely wants to align with the views of its international peers.The country had been moving towards travel rule implementation in the past but in a less decisive way. Two years ago, Japan’s Financial Services Agency (FSA) requested virtual asset service providers (VASPs) to implement the travel rule. In a self-regulatory approach in 2022, the country’s Virtual Currency Exchange Association issued a recommendation for members to apply the rule.Those approaches lacked teeth, leading to a cabinet decision to amend existing legislation late last year and this more recent move to apply and enforce the rule.Regulatory frameworkWhile Japan may not be top of the class in terms of AML regulation relative to crypto, it is a forerunner in terms of crypto regulation generally. It was the first country in the world to suffer a serious crypto-related failure when the Mt.Gox cryptocurrency exchange collapsed in 2014.The fall-out from that collapse led to the Japanese introducing more stringent regulations although it took until 2017 to get them implemented. As a consequence, when the next major collapse occurred, the fall of FTX in November 2022, the Japanese have fared much better than investors located elsewhere. Regulation meant that a separate Japanese entity, FTX Japan, was established. It had to adhere to stricter conditions, meaning that FTX Japan customers have been allowed to withdraw their funds since February while their international counterparts must undergo a much longer process to recover their funds.

South Korea's ruling party forms task force to expedite stablecoin legislation

South Korea’s ruling Democratic Party has set up a new task force to accelerate the creation of a clear regulatory framework for stablecoins, aiming to unify competing legislative proposals ahead of government guidelines expected in October. According to Etoday, the nine-member group, chaired by Representative Lee Jung-moon of the National Policy Committee, is composed of lawmakers from three key parliamentary committees. Its primary objective is to consolidate the party's position on digital asset policy and coordinate with the Financial Services Commission (FSC) to establish a definitive rulebook for the burgeoning sector. Lee stated that the task force would work to harmonize multiple stablecoin bills already circulating within the party, noting that there was mounting pressure from both regulators and the private sector. He explained that government agencies had urged swift legislative action, while financial institutions and exchanges preparing to launch won-pegged stablecoins were waiting for regulatory certainty.Photo by SC Jang on UnsplashRegulatory debate over capital standardsA central point of contention for the task force will be establishing appropriate capital requirements for stablecoin issuers. Current proposals vary in scope, with suggested thresholds ranging from 500 million won (approximately $358,000), a figure intended to encourage fintech innovation, to as high as 5 billion won (about $3.58 million) to prioritize investor protection. The committee is tasked with striking a balance between fostering market growth and ensuring financial stability. Seoul's initiative reflects a broader global movement toward formal oversight of fiat-backed digital currencies. The U.S. passed its GENIUS Act for stablecoins in July, while the EU has implemented its Markets in Crypto-Assets (MiCA) regulation. Similarly, Japan amended its Payment Services Act in 2023 to restrict stablecoin issuance to licensed banks and registered financial firms. Former White House crypto advisor’s inputThe push for clear rules has drawn keen interest from industry leaders. Speaking at Korea Blockchain Week 2025 in Seoul, Bo Hines, chief executive of Tether USAT, stressed the regulatory clarity provided by the GENIUS Act in the U.S. According to ZDnet Korea, he noted that his company's new dollar-backed token, USAT, is designed for full compliance with U.S. law, featuring one-to-one reserves and audits by top-tier accounting firms to attract institutional investors. Hines, a former digital assets adviser at the White House, clarified that USAT is intended to serve the regulated U.S. market, complementing Tether’s flagship product, USDT, which has a global user base exceeding 500 million. He also discussed Tether’s view of South Korea as a key market, pointing to the significant USDT trading volumes there. Hines encouraged the country to adopt comparable stablecoin standards and expressed optimism that it would move toward a more open and efficient global financial network. With the FSC’s guidance approaching, the Democratic Party’s task force is working to reconcile differing legislative proposals. The resulting framework will shape the pace at which stablecoins move from pilot projects to an established part of South Korea’s financial system.
