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.

Mt. Gox moves $9B in Bitcoin for first time in years

Wallets belonging to the defunct Japanese Bitcoin exchange Mt. Gox have transferred over 140,000 Bitcoin (BTC), valued at approximately $9 billion, to an unknown address.  Sell-off fearsThis significant movement began in the early hours of Tuesday morning in Asia, marking the first such transfer from Mt. Gox’s cold wallets in over five years. Julio Moreno, head of research at CryptoQuant, initially confirmed that 12,239 Bitcoin had been transferred from Mt. Gox over the course of an hour. A short time later, he provided an update on X, stating:"All coins have been transferred to a new address." Despite market disquiet, the prevailing view which subsequently emerged is that the transfer is believed to be part of a plan to distribute assets back to creditors before the October 31, 2024 deadline. Alex Thorn, head of research at Galaxy Digital, shared his perspective on X, suggesting that most of the transferred Bitcoin would likely be held by creditors rather than being sold on the open market. Despite these reassurances, the market reacted negatively for a time. Bitcoin's price dropped by 1.4% since the start of Asian trading hours, falling to a low of $67,680 from a Monday high of over $70,000.Photo by Kanchanara on UnsplashNo Bitcoin FiresaleTo quell fears of a massive Bitcoin sell-off, Mark Karpeles, the former CEO of Mt. Gox, addressed the situation on X. He stated: “As far as I know, everything is fine with MtGox. The trustee is moving coins to a different wallet in preparation for the distribution that will likely happen this year. There is no imminent sale of bitcoins happening." Rehabilitation trustee Nobuaki Kobayashi also issued a press release, clarifying that no sale of Bitcoin or Bitcoin Cash (BCH) had taken place. He assured that the group was "managing bitcoin and bitcoin cash in a secure manner." Wallet activity reveals that these movements were executed through thirteen transactions. A test transaction worth $3 was made on May 20, followed by another smaller transaction of $160 early Tuesday. The remaining transactions varied from $1.2 million to $2.2 billion worth of Bitcoin. Bitinfocharts data shows that all of Mt. Gox's Bitcoin has now been consolidated into a single wallet. A long road to repaymentIn September 2023, Mt. Gox’s trustee announced that the repayment deadline had been extended by 12 months to October 31, 2024. It looked like repayments were imminent in November. However, those communications referenced cash repayments rather than the distribution of Bitcoin and Bitcoin Cash. Some cash repayments had started in December 2023. Speculation in January that the bankruptcy estate would begin the distribution of Bitcoin led to market fears of the impact that would have on the Bitcoin unit price. The extension provided a longer timeframe for preparing the distribution of assets to creditors. Mt. Gox, launched in 2010, quickly rose to prominence, becoming the largest Bitcoin exchange by 2013, handling 70% of all Bitcoin trades worldwide. However, the exchange faced a dramatic downfall in early 2014.  It suspended trading and stopped all withdrawals after losing hundreds of thousands of Bitcoin in a hack. Subsequently, the site went offline, and the company filed for bankruptcy protection after losing over 800,000 Bitcoins. Creditors have been waiting for repayment ever since.
