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.

Korean Banks Impose Crypto Exchanges to Maintain a Reserve of at Least 3B KRW

Korean Banks Impose Crypto Exchanges to Maintain a Reserve of at Least 3B KRWIn a significant step towards regulating the cryptocurrency market and ensuring the safety of virtual asset users, South Korea’s Federation of Banks (KFB) has collaborated with financial authorities and virtual asset exchanges to establish the “Guidelines for the Operation of Real Name Accounts for Virtual Assets.” The KFB, as a group of banks and financial institutions, facilitates cooperation between its members and promotes the development of the financial industry.Photo by rc.xyz NFT gallery on UnsplashThe guidelines come as a response to the increasing need for stronger money laundering prevention measures and standardization in the crypto industry. The first step towards this was taken in 2018 when crypto exchanges became obliged to establish a real name account at a bank in order to provide Korean Won (KRW) deposit and withdrawal services to their customers. Currently, the exchanges that won such bank accounts are Upbit, Bithumb, Coinone, Korbit, and Gopax.However, this policy brought with it a set of challenges, including differing practices among various cryptocurrency exchanges, leading to inconveniences for users. Additionally, varying user protection measures, such as reserve requirements, caused confusion in the market.3 billion KRW in reservesTo address these issues, the new guidelines aim to clarify how banks operate cryptocurrency real-name accounts and bolster overall security. One of the key changes is the requirement for crypto exchanges to maintain a reserve of at least 3 billion KRW ($2.36 million). This reserve fund serves as a precautionary measure to address potential financial losses resulting from hacking incidents or system failures at crypto exchanges.Furthermore, the guidelines mandate banks to manage deposit and withdrawal limits by categorizing user accounts into limited and normal accounts. A limited account will not be converted to a normal account, which grants higher deposit and withdrawal limits, until the user’s transaction purpose and the source of funds are verified.Enhanced due diligenceIn addition, banks will perform annual enhanced due diligence (EDD) for individual account holders. This thorough review will encompass users’ identification, transaction purposes, and the origin of funds.User asset segregationTo safeguard users’ funds, crypto exchanges will be required to ensure that customer deposits are held separately or placed in trust. Regular due diligence at crypto exchanges will also be conducted by banks, with mandatory visits occurring at least once a month. Moreover, third-party services will be engaged to perform independent due diligence every quarter on crypto exchanges, providing an additional assessment of their operations.The official launch of these new guidelines is scheduled for January of next year. However, the requirement of depositing at least 3 billion KRW will come into effect earlier, starting in September of this year. Additionally, the implementation of guidelines for expanding deposit and withdrawal limits is anticipated in March of next year.

Institutional support expected to cushion crypto volatility, analyst says

Despite ongoing fluctuations in the cryptocurrency market, analysts suggest that sustained institutional activity is likely to underpin a near-term rebound. As Bitcoin recovered above $90,000 on Dec. 5, market observers began weighing potential risks against growing evidence of corporate and sovereign adoption.Photo by Austin Hervias on UnsplashStructural risks seen as limitedAccording to South Korean news outlet Etoday, Hong Sung-wook, a researcher at NH Investment & Securities, said that the recent slump in both Bitcoin and Strategy stock may weigh on shareholders but does not fundamentally threaten the company’s solvency. He noted that concerns that typically emerge during Bitcoin downturns seldom reflect new underlying risks. Addressing the potential removal of Strategy from the MSCI index, pending review results expected by Jan. 15, Hong indicated that the impact would likely be limited, as the firm has already exhausted its capacity to make additional Bitcoin purchases. However, he cautioned that prolonged share price weakness could force companies to reevaluate digital asset treasury (DAT) models. Such a shift, he warned, could trigger corporate sell-offs that would burden the broader market. Hong also addressed concerns related to stablecoins and future technology. Despite S&P Global Ratings assigning Tether its lowest grade of "weak," Hong observed that the issuer maintains reserves exceeding the USDT in circulation, rendering a mass withdrawal crisis unlikely. Regarding the threat of quantum computing, he argued that the timeline remains uncertain and that the Bitcoin network could mitigate future risks through consensus-driven protocol upgrades. Policy moves may offer market tailwindsLooking ahead, the analyst identified several constructive developments that could bolster the market, including the potential passage of a U.S. crypto market structure bill early next year. He also pointed to the anticipated nomination of Kevin Hassett as Federal Reserve Chair by President Trump. Hassett is expected to favor interest rate cuts, creating a potentially favorable macro environment. Additionally, Vanguard’s decision to permit the trading of select third-party crypto ETFs and mutual funds was cited as significant, given the asset manager’s historically conservative stance on digital assets. While the market has shifted into a broader risk-off mode, institutional demand for Bitcoin has continued to build, including activity that began well before the recent pullback. The Czech central bank recently established a $1 million test portfolio comprising Bitcoin, a USD stablecoin, and a tokenized deposit to research payment futures, though it clarified that it does not currently plan to add digital assets to its international reserves. In the academic sector, a Form 13F filing with the U.S. SEC revealed that Harvard Management Company, which oversees a $56.9 billion endowment, held 6.8 million shares of BlackRock’s iShares Bitcoin Trust ETF (IBIT) as of Sept. 30, a threefold increase from the previous quarter. Furthermore, BlackRock CEO Larry Fink reportedly stated at the New York Times DealBook Summit 2025 that multiple sovereign wealth funds have begun accumulating Bitcoin, according to Forbes. Korean banks advance crypto integrationThis shift toward institutional acceptance is also materializing within South Korea’s traditionally conservative banking sector. The Maeil Business Newspaper reported that Woori Bank recently became the first major South Korean lender to display real-time Bitcoin prices on its trading floor, allowing dealers to track the asset alongside equities and foreign exchange rates. Concurrently, Hana Financial Group announced a partnership with Dunamu, the operator of the Upbit exchange, to develop blockchain-based remittance services, according to The Korea Economic Daily. By leveraging Hana’s global network and Dunamu’s technology, the initiative aims to reduce settlement times and costs for cross-border payments. Hana intends to introduce the technology for transactions between its Korean offices and overseas branches as early as the first quarter of next year, with broader expansion planned as domestic regulations evolve. Hana intends to launch the service at overseas branches as early as the first quarter of next year, with gradual expansion planned as domestic regulations evolve.

Hang Seng Ponders Crypto Product Offering

Hang Seng Ponders Crypto Product OfferingHang Seng Investment Management Co., the largest exchange-traded fund (ETF) manager in Hong Kong, is considering entering the decentralized ecosystem.According to a report in local news media in Hong Kong on Wednesday, Li Peishan, the firm’s Director and Executive President, stated that Hang Seng is paying close attention to the development of digital assets. She clarified that the company is examining the possibility of including digital assets within its existing investment product offering.Photo by Jonathan Borba on UnsplashCrypto ETF expansionThis news comes shortly after HSBC, one of the largest banks in Hong Kong, introduced Bitcoin (BTC) and Ethereum (ETH) ETFs to its customers, becoming the first bank in the region to do so. This development has opened up possibilities for greater cryptocurrency adoption in the area.While most people in the space recognize that the authorities in the US have gone too far in their clampdown on the digital assets space, it’s interesting to note that recent weeks have seen a plethora of established TradFi players filing Bitcoin spot ETF applications. That list includes the world’s largest asset manager, BlackRock, multinational financial services firm Fidelity Investments, WisdomTree, VanEck, and others.Assessing potentialPeishan stated that while the company does not have a specific plan to develop a crypto ETF, Hang Seng is actively assessing the potential of incorporating digital assets into their existing investment products. She highlighted the remarkable growth in the average daily asset management scale, which has surged by 80% since December and has surpassed HK$12 billion.On June 24, Leung Fung Yee, the CEO of the Securities and Futures Commission of Hong Kong (SFC), emphasized the importance of crypto service providers embracing the next generation of the web and finance. He expressed Hong Kong’s ambition to establish itself as the central hub for crypto companies, fostering innovation within the region.Responding to Yee’s statement, the Hong Kong Virtual Assets Consortium (HKVAC) announced the inclusion of XRP, SHIB, and ADA in its newly developed HKVAC index. The creation of the HKVAC index aims to assist investors in analyzing the potential of cryptocurrencies and gaining insights into their prospects.The digital assets landscape in Hong Kong is evolving rapidly, driven by increasing interest in the asset class and the recognition of their transformative potential. Hang Seng Investment Management’s exploration of the decentralized ecosystem signifies the growing demand for exposure to cryptocurrencies among traditional financial institutions.TradFi IntegrationThe introduction of Bitcoin and Ethereum ETFs by HSBC represents a significant milestone in the adoption of cryptocurrencies within the traditional banking sector. This recent indicator from Hang Seng suggests that we are likely to see more developments unfold within the ETF space in Hong Kong in the not-too-distant future where digital assets are concerned. That view is further endorsed by the findings of a recent report produced by the Hong Kong Stock Exchange, pointing to the yet-to-be-realized potential of crypto ETFs.As the industry continues to mature, the integration of digital assets into traditional investment products is likely to become increasingly common, leading to a more diversified and inclusive financial ecosystem.
