These transactions are conducted within the embedded secure element (eSE) chip of Samsung Electronics’ mobile devices, which holds one of the highest levels of security certification, CC EAL 6+.The Evaluation Assurance Level (EAL) is a numeric grading system that measures the security level of tech products and systems according to the Common Criteria (CC) security standard. It ranges from EAL0 to EAL7, with EAL7 representing the highest level of security.Leveraging this technology, the BOK and Samsung will continue their joint research to enhance security in offline payments using Samsung Galaxy smartphones and watches. Additionally, they aim to provide support for stable payments in situations where network connectivity is disrupted, such as during disasters.Growing interest in CBDCsGiven the global interest in CBDCs, with central banks worldwide exploring their potential, the research collaboration between the BOK and Samsung assumes great significance. The results of this partnership will guide further cooperative efforts to develop the international CBDC ecosystem.BOK Senior Deputy Governor Lee Seung-heon emphasized the significance of the joint achievement, expressing optimism that the partnership would keep Korea at the forefront of offline CBDC technology.Samsung’s Executive Vice President Choi Won-joon underscored that the company’s collaboration with the Korean central bank allowed Samsung to utilize its advanced security technology in digital currency. He expected their combined efforts would considerably contribute to the global development of CBDC technology.

Major Korean Crypto Exchanges Strengthen on NFT Projects Despite Crypto WinterDespite crypto winter, major Korean cryptocurrency exchanges Upbit and Bithumb strengthened on staff and included new non-fungible token (NFT) projects.US Tightening Policy Effects on Crypto MarketAccording to the electronic disclosure system operated by the Financial Supervisory Service, Upbit’s operator Dunamu saw a net income of 130.8 billion won last year, down by 94% from 2.21 trillion won. Bithumb also experienced a decline of 85% from 648.4 billion won to 95.4 billion won. This downturn is reportedly attributed to the tightening monetary policy by the US and weaker market sentiment on risky assets.Insights on Korean NFT MarketBoth exchanges, Upbit and Bithumb, having seen meager profitability in crypto trading, recruited more talent to embark on NFT projects. However, the picture is not so rosy for these new endeavors, considering the tepid NFT trade volume. According to The Block, the NFT trade volume last month reached $983.4 billion, which is lower than $1.4 trillion, the previous month’s record.The NFT trade volume on Upbit last month also experienced year-on-year and month-on-month decreases of 48.6% and 14.5%, respectively.Last week, Dunamu CEO Sirgoo Lee said in a shareholders’ meeting that its NFT projects are underachieving and that he is reconsidering the new projects from scratch. He added that Dunamu will build a solid foundation in Korea while promoting global businesses starting from the US through Levvels, a blockchain-based platform jointly established by Dunamu and the entertainment company HYBE.Outlook on the Korean MarketBithumb, on the other hand, will bolster new projects through Bithumb Meta and Rotonda. Bithumb Meta recently launched the beta service of its original metaverse Naemo Market where users can use NFTs to decorate their own personal digital space. Rotonda released Burrito Wallet last February to allow waller holders to store NFTs, cryptocurrencies, and fiat currencies.Meanwhile, there was a mixed outlook on the Korean crypto market. One person said in an interview with Hankooki that greater workforces in the country’s leading crypto exchanges could suggest the market’s growth, but also pointed out that their bigger sizes might hinder them from maneuvering when faced with other unexpected risks.

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.
