OKX maintains robust asset reserves with 103% BTC backing

South Korea’s largest crypto exchange, Upbit, suffered a security breach on Nov. 27 that resulted in the theft of 44.5 billion won ($30.4 million) in digital assets, all taken from the exchange’s hot wallets. The stolen tokens were all Solana-based, and Upbit CEO Oh Kyoung-suk said in a statement that no users will incur losses, as the company will cover the full amount with its own reserves.Photo by FlyD on UnsplashHot-wallet breach hits 24 tokensThe exchange said in a statement that the compromised tokens were transferred to an unknown external wallet at around 7:42 p.m. UTC on Nov. 26. In total, 24 cryptocurrencies were affected, all within the Solana ecosystem. The stolen assets ranged from infrastructure tokens such as Solana (SOL) to staking-related assets like Jito (JTO), along with the stablecoin USD Coin (USDC) and memecoins including Bonk (BONK), Moodeng (MOODENG), and Official Trump (TRUMP). According to Oh, the breach was followed by an emergency security review of the affected networks and wallets. He added that all remaining assets were moved to cold storage to prevent further unauthorized transfers. Oh also said the exchange is working to trace the stolen assets and block on-chain movements wherever possible, noting that Solayer (LAYER) tokens worth 2.3 billion won ($1.6 million) have already been frozen. Upbit is also reaching out to relevant projects and institutions for assistance. This marks Upbit’s second theft case. The first took place on Nov. 27, 2019, exactly six years ago to the day, according to News1. Authorities focus on Lazarus’ involvementFinancial authorities are investigating the incident, and North Korea’s Lazarus Group is being treated as the leading suspect, the Maeil Business Newspaper reported. Lazarus is also believed to have been behind the 58 billion won ($40 million) worth of Ethereum (ETH) stolen from Upbit in 2019. A government official told the paper that the latest breach did not appear to stem from a server intrusion but may have involved a stolen administrator account, allowing the attackers to impersonate internal staff and move assets—similar to the method used in the 2019 case. Security analysts echoed that assessment. One investigator said the stolen funds moved through exchange wallets before being mixed, a pattern often linked to Lazarus. He added that mixers, which are prohibited in Financial Action Task Force (FATF)-member jurisdictions, make tracing difficult and that attackers typically route assets through countries outside that framework, further pointing to North Korea. Following the incident, Upbit suspended deposits and withdrawals for all assets and said services will resume once security is fully verified. The halt has also affected trading dynamics on the exchange, with CryptoQuant CEO Ki Young Ju noting that retail investors are fueling altcoin spikes as arbitrage bots remain offline. Dunamu, Naver set $6.8B growth planThe security crisis struck at a particularly sensitive moment for Upbit’s operator, Dunamu, overshadowing what was intended to be a celebratory corporate milestone. On that same day, Dunamu, Naver, and Naver Financial held a joint press conference to outline their global expansion strategy. Dunamu brings its blockchain and crypto infrastructure, Naver contributes its position as Korea’s dominant search engine, and Naver Financial adds its payment platform serving 34 million users. The event came after reports that Naver Financial and Dunamu had approved a merger plan through a comprehensive share swap, with the ratio set at 2.54 to 1. The three companies said they will combine their respective strengths to invest 10 trillion won ($6.8 billion) over the next five years in building an ecosystem centered on Web3 and artificial intelligence (AI).During the press conference, Naver CEO Choi Soo-yeon said no decisions have been made on a Nasdaq listing for the newly combined Naver Financial–Dunamu entity or on whether it might eventually merge with Naver, according to TechM. She said dual listings remain a matter requiring national consensus. Choi also noted that while Naver Financial is a Naver subsidiary, Dunamu is the larger partner, and a later merger between the combined entity and Naver is unlikely.

Lambda256 and CryptoLab partner to pioneer privacy-enhanced blockchain technologyLambda256, the Blockchain-as-a-Service (Baas) arm of South Korea’s largest crypto exchange Upbit, has signed a business agreement with private AI technology developer CryptoLab to develop and commercialize technology that can enhance the privacy of data on blockchain networks, according to local news outlet Kyunghyang Games on Friday (KST).Photo by GuerrillaBuzz on UnsplashAdvanced privacy measuresThe two firms will work together to develop various blockchain-based service platforms, such as a token securities offering (STO) platform, that will be equipped with strengthened privacy protection technology for data stored on blockchains.Innovation unleashedLambda256 has been leveraging its Web3 developer platform Luniverse to work with a plethora of businesses, including those in the security token industry, to help them build, deploy and manage blockchain networks. Some of its solutions include DID, a blockchain-based identity management system; Trace, a blockchain verification and tracking system; and Point, a blockchain-based loyalty rewards solution.CryptoLab, on the other hand, has developed in-house homomorphic encryption technology that can encrypt data while allowing that data to still be operated on. The firm’s CEO, Chun Jeong-hee, who is also a professor at Seoul National University’s Department of Mathematical Science, was selected as a Fellow of the International Academy of Cryptography (IACR) this year in recognition of his contributions to the development of the field of cryptography.“By combining Lambda256’s blockchain platform with our homomorphic encryption technology, we look forward to exchanging our technology and capabilities,” said Shin Jun-bum, CTO of Cryptolab. Jason Lee, CISO of Lambda256, also reaffirmed the companies’ joint goal of solving data privacy issues that occur in the blockchain space. He added that they would take this opportunity to bring blockchain to fields like finance and healthcare that are sensitive to data privacy.

Top Korean Crypto Exchanges Witness Surge in Listings and Delistings During H1In the first half of this year, South Korea’s top five cryptocurrency exchanges experienced notable growth in the number of newly added cryptocurrencies to their platforms. However, they also observed a significant surge in the number of cryptocurrencies being delisted.Photo by Shubham Dhage on UnsplashDelisting and listingAccording to a report by local news outlet Etoday, the nation’s five leading exchanges Upbit, Bithumb, Coinone, Korbit, and Gopax ceased trading for a total of 51 cryptocurrencies during the first six months of this year. This marked an 88% increase compared to the 27 cryptocurrencies delisted in the previous six-month period. During the first half of last year, the number of delisted tokens was 48.Among the five exchanges, Coinone took the lead by delisting the highest number of cryptocurrencies, totaling 24. Bithumb followed with 14 delisted tokens, Gopax with six, Upbit with five, and Korbit with two. Notably, Coinone continued its delisting spree this month, removing an additional five cryptocurrencies from its platform. Most cryptos were delisted because their projects and services were not operating normally.The significant number of delisted tokens at Coinone appears to be linked to the involvement of its former employees in the unlawful listing of certain tokens. These individuals reportedly received bribes in exchange for listing a total of 46 cryptocurrencies on the trading platform. Among these tokens were PICA and PURE, which are no longer traded on the exchange.Only five cryptocurrencies were delisted according to the decision made by the Digital Asset eXchange Alliance (DAXA), a self-regulatory group consisting of the aforementioned five crypto exchanges. The delisted tokens were REP, BASIC, OMG, SRM, and PCI. This indicates that most of the affected cryptocurrencies were exclusively traded on one of the DAXA member exchanges, indicating that DAXA’s listing and delisting guidelines were largely ineffective.Meanwhile, there has been a notable surge in the number of newly added cryptocurrencies. Bithumb, for instance, took the lead by listing an impressive 63 new tokens, nearly three times the number listed by Upbit (22). In the same vein, Coinone added 14 tokens, while Korbit and Gopax followed with six and three new listings, respectively.Profit squeezeLast year, crypto trading platforms adopted a conservative approach when it came to listing and delisting procedures, prioritizing investor protection. However, their stance shifted as the global crypto market encountered a significant decline in trading volume amid crypto winter. This decrease in trading activity subsequently led to reduced operating profits, compelling the platforms to list more cryptocurrencies.With the exception of Upbit, which maintains a dominant market share in the nation, the outlook on crypto exchanges appears more or less grim. In particular, Coinone, Korbit, and Gopax are in the red. Bithumb, while still in profit, saw its operating profit last year falling 80% year-over-year to 163.5 billion KRW ($127.9 million). This trend continued this year, with Bithumb’s operating profit In the first quarter of this year recording 16.2 billion KRW, an 80% decrease compared to the same period last year.In light of this development, an industry insider, who wished to stay anonymous, told Etoday that while the market’s total trading volume is witnessing a considerable decline, Upbit’s dominance is still growing. This individual also noted that the decrease in trading volume and the resulting deficit are exerting pressure on exchanges to expand their cryptocurrency listings.
