Hana Financial Group Joins Hands with Netmarble to Attract Digitally Savvy Youths to the Metaverse

South Korea’s GDAC Suffers $13M hackSouth Korean cryptocurrency exchange, GDAC, has suffered a significant hacking incident that has resulted in the loss of approximately 23% of its custodial digital assets.©Pexels/PixabayThe hack occurred on Sunday when some of the exchange’s hot wallets were breached, and the stolen assets were transferred to an unidentified wallet. GDAC reported the incident on Monday and disclosed that the exchange lost over $13.1 million in Bitcoin, Ether, Wemix, and USDT, with more than $10 million in Wemix.According to blockchain analytics firm Arkham Intelligence, the hacker has since swapped the USDT for ETH, sending 461 ETH to cryptocurrency tumbler, Tornado Cash. The hacker used three separate wallets to take funds from two of the exchange’s hot wallets. Arkham has labeled the wallets as follows:GDAC Hacker 1: 0x244615D99684175d31369332039b2D84ce925EC5GDAC Hacker 2: 0x62B5eb2cb925Ce2898f9327B235b3228e7Cac1C2GDAC Hacker 3: 0x87597bDB421482190e223aCa0A4DEAd75AB0a98DGDAC deposits/withdrawals suspendedGDAC has suspended its withdrawal and deposit services and reported the incident to the Korea Internet and Security Agency and the Financial Intelligence Unit. The exchange has also requested other cryptocurrency exchanges to block incoming transactions from suspicious addresses.In a notice posted on its website, GDAC CEO Seunghwan Han apologized for the suspension of deposits/withdrawals and concern relative to the hack, adding that the firm will be working towards investor protection and safe withdrawal of funds in due course. GDAC also posted the breakdown of the digital asset quantities lost in the hack, with the hacker stealing 60.80 BTC, 350.5 ETH, 10,000 WEMIX and 220,000 USDT.Crypto hacks increasingThis hacking incident comes at a time when cryptocurrency hacks have been on the rise. According to blockchain analytics firm Chainalysis, illicit actors stole $3.8 billion worth of assets last year, the largest one-year loss in crypto’s history. In addition, other crypto platforms have also suffered notable hacks and exploits in the past 15 to 18 months. Axie Infinity’s Ronin bridge, for example, suffered a $625 million hack last year, and decentralized-finance protocol Sushi was exploited for $3.3 million on Sunday.GDAC is not the only South Korean cryptocurrency exchange to suffer a significant hacking incident. In 2018, Coinrail was hacked, resulting in the loss of approximately $40 million worth of assets, and in 2021, Upbit suffered a $50 million hack.In response to these incidents, South Korea has taken steps to tighten regulations around cryptocurrency exchanges. In March 2021, the country’s Financial Services Commission issued a revised regulation that requires cryptocurrency exchanges to maintain stricter anti-money laundering measures and report suspicious transactions.The GDAC hack is a stark reminder of the risks associated with cryptocurrency investing and the importance of implementing robust security measures. Investors and cryptocurrency exchanges should take note of this incident and ensure that they have adequate security measures in place to protect against potential hacks and exploits.

Hitachi collaborates with Concordium on biometric crypto walletJapan’s Hitachi Solutions, a subsidiary company of the Hitachi multinational conglomerate, has joined forces with the Concordium Foundation, unveiling a collaboration that centers on a state-of-the-art biometric crypto wallet.Photo by Nuno Antunes on UnsplashAlternative approach to securing cryptoAnnounced on Tuesday by the Concordium Foundation, a Swiss-based development team behind the Concordium layer one blockchain, this “proof of technology” initiative has the potential to fundamentally change how users access and secure their cryptocurrency accounts.Breaking away from traditional methods, the proposed biometric crypto wallet leverages users’ fingerprints or facial scans to generate a set of seed words, eliminating the need for users to store or remember them. This novel approach simplifies the restoration process, allowing users to recover their accounts with a mere biometric scan.Improving UXIf crypto and Web3 are to be adopted by ordinary people en-masse, user experience has long been identified within the sector as an area that still requires development. Making users responsible for the storage of a private key is fraught with difficulty, given the likelihood of private keys being lost or compromised.Various approaches are being taken to solve this issue. Tangem Wallet is one such alternative that utilizes near-field communication (NFC) in combination with an app and a card with an inbuilt chip, negating the need for the user to memorize a private key.This biometric-centered approach from Hitachi and Concordium represents another user-friendly approach to the problem of user authentication, harnessing the power of Hitachi’s Public Biometric Infrastructure (PBI) and Concordium’s self-sovereign identity framework. The result is an account creation process based entirely on biometric data, enhancing both security and user convenience.Complementary technologyConcordium’s network, with its stringent ID process for account creation to combat malicious activities, stands to gain substantial benefits from this technology. The biometric wallet will fortify users’ access to their IDs, a critical aspect of network security. Moreover, the technology’s applicability extends beyond Concordium, offering potential integration with any blockchain network.Users of the biometric wallet will have the flexibility to unlock their accounts either by regenerating seed words through a biometric scan or by decrypting a copy of the seed words. This dual-layered approach ensures that access is granted solely through the user’s unique biometric data, enhancing security and mitigating the risk of loss or theft.Developing this cutting-edge technology poses challenges, particularly in handling the inherent “fuzziness” of biometric data, where no two scans produce identical results, even from the same individual. Hitachi’s team addressed this by employing fuzzy key generation and specialized error correction technology, effectively distinguishing between scans.Unlike traditional crypto wallets that necessitate secure storage of seed words, the biometric wallet by Hitachi and Concordium, alongside solutions like multiparty-computation wallets and magic links, aims to overcome this hurdle. The goal is to resolve the issue of lost backup, a significant barrier to wider crypto adoption.This is not Hitachi’s first foray into the crypto/blockchain space. In mid-November the company announced a collaboration with the Japan Exchange Group (JPX), banking giant Nomura and Nomura portfolio company BOOSTRY to launch a $69 million digital green bond on the blockchain. In October Hitachi joined a consortium of Japanese companies with a view towards developing decentralized identity technology.

Former Binance CEO, Changpeng Zhao (CZ), facing criminal charges and awaiting sentencing in the United States, has been denied his request to return to the United Arab Emirates (UAE) by a U.S. federal judge, according to Bloomberg. The decision, rendered by the U.S. District Judge Richard Jones, reinforces the restrictions on CZ's movements in the months leading up to his scheduled February sentencing. In a filing on Friday, Judge Jones rejected CZ's motion seeking permission to travel to the UAE, where his children reside with former talk-show host and Binance co-founder, Yi He. The specific grounds for the denial were sealed, providing limited insight into CZ's argument against the judge's repeated constraints. However, CZ's legal team hinted that the motion involved "medical information regarding Mr. Zhao’s child."Photo by Kai Pilger on UnsplashSecond travel request denialThis ruling, dated Dec. 29, marks the second time CZ's request to travel to the UAE has been turned down. Earlier in the month, Judge Jones sided with U.S. prosecutors, citing CZ's substantial wealth abroad and the absence of an extradition treaty between the U.S. and the UAE, making him a potential flight risk. CZ had previously pleaded guilty to violating the Bank Secrecy Act and resigned as CEO of Binance, the world's largest digital asset exchange. Binance, as an entity, reached a $4.3 billion settlement related to sanctions and money transmission violations. Singaporean Richard Teng, Binance’s former head of regional markets, has been installed as CEO in CZ’s place. Despite legal challenges, Zhao secured release on a $175 million personal recognizance bond after pleading guilty. The billionaire posted $15 million from a trust account and had three guarantors pledge over $5 million in collateral to secure the bond. The court order allows CZ to remain free, but he is prohibited from leaving the U.S. until his sentencing. 40 million new usersIt’s not all bad news for Zhao’s Binance. In a recent report titled "State of The Blockchain: Binance’s 2023 in Review," Binance highlighted its significant growth in 2023, welcoming over 40 million new users — a 30% increase from the previous year. The report emphasizes the company's commitment to user-centric principles, boasting 170 million registered users and 431 assets available for trading across 1,785 trading pairs by the year's end. Key achievements outlined in the report include robust growth in crypto payment services, P2P trading and earning platforms. Binance Pay and Card experienced a 54% surge in users and the P2P platform recorded an 18% increase in trades and a 39% rise in users. Binance Earn, a crucial component of Binance's product suite, saw a 35% increase in users and a 16.8% rise in the total value locked within its products. Higher net worth2023 hasn’t been all bad for CZ on a personal basis either. His wealth has seen a substantial increase of approximately $25 billion in 2023 despite the legal turmoil. His $37 billion net worth primarily stems from his controlling stake in Binance.Despite potential imprisonment, CZ stands atop the list of cryptocurrency entrepreneurs whose fortunes have witnessed substantial growth this year, ranking 35th in the Bloomberg Billionaires Index.
