Upbit suffers $30M breach, overshadowing Dunamu’s major merger announcement

Markets·November 28, 2025, 2:27 AM

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.

Hot-wallet breach hits 24 tokens

The 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’ involvement

Financial 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 plan

The 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 1 to 2.54. 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.

Arthur Hayes: Chinese monetary policy could ignite crypto market

Arthur Hayes: Chinese monetary policy could ignite crypto marketArthur Hayes, Co-Founder of Seychelles-incorporated crypto exchange and derivatives platform BitMEX, suggests that China could inject a substantial amount of credit into its economy, potentially giving a boost to Bitcoin and the broader crypto market.Photo by Eric Prouzet on UnsplashPotential flood of yuan creditThe firebrand crypto OG outlined his thoughts on the matter in a blog post which was published on Monday. Hayes discussed how, although China has currently made credit expensive in order to hold back credit growth and inspire confidence in the economy, its monetary authorities might be gearing up to flood the economy with yuan credit, creating a favorable environment for cryptocurrencies.He outlined a series of factors contributing to this potential surge in Chinese credit. He pointed to the interplay between U.S. monetary policy and the Chinese yuan, emphasizing how recent U.S. actions are laying the groundwork for China to issue substantial credit, particularly to its struggling property sector.Describing U.S. policy as “weakening the dollar by issuing more Treasury bills,” Hayes noted the consequent decline of the dollar index (DXY) throughout November. He argued that the weaker dollar gives China the flexibility to increase yuan credit without significant depreciation, possibly even leading to yuan appreciation.If the Federal Reserve at a minimum holds rates and better still, starts to cut rates, China will be in a position to pursue the stimulus needed for its property market and for infrastructure spending.Hong Kong as the gateway to capital marketsAccording to Hayes, the global monetary dynamics set in motion by these factors could be advantageous for Bitcoin and the broader cryptocurrency market. He explained that the bulk of the financing will trickle down into speculation within the financial markets. If China starts printing yuan, the capital is likely to flow into global markets, supporting the prices of various risk assets.But how can this happen, given that speculation and crypto trading are prohibited in China? Hayes’ view is that Hong Kong is now China’s gateway to the global capital markets. Wealthy Chinese individuals now bank via Hong Kong. As we have seen, the autonomous Chinese territory has a workable regulatory framework in place and is now actively licensing crypto exchanges and brokers. Consequently Bitcoin and crypto, generally, could be among the risk assets benefiting from an influx of capital.Furthermore, the BitMex co-founder believes that as yuan credit becomes abundant, the global demand for dollar credit and liquidity may decrease. Given that the dollar is a primary funding currency, a fall in the price of credit could lead to a rise in fixed-supply assets like Bitcoin and gold in dollar terms.Hayes concluded what is a long and detailed blog post by stating:“I will continue moving money out of T-bills and into crypto because I want to get in now before it becomes apparent through the data that China’s money printer is going brrrrr.”He suggested that Chinese New Year, which occurs in mid-February of next year, could be the time in which that extra credit materializes in China. Hayes’ latest assertion comes on the back of a bold claim he made last month when he suggested that bitcoin could reach a unit price of $1 million by 2026.

SafePal invests in & partners with Switzerland’s Fiat24

Singaporean crypto wallet provider SafePal has announced a strategic investment in Swiss bank Fiat24, together with the launch of a number of financial services. The partnership is a significant milestone in bridging the gap between the crypto world and real-world financial utilities.Photo by Henrique Ferreira on UnsplashVisa card and in-app bankingThe company outlined in a blog post on March 7 that the centerpiece of this collaboration is the introduction of a crypto-focused Visa card and in-app banking services, both designed to streamline the integration of digital assets into everyday transactions. The default deposit currency for these services is the dollar-pegged stablecoin USD Coin (USDC), providing users with a stable foundation for their financial activities. Through the SafePal mobile wallet app, users can convert their cryptocurrency holdings into USDC via Ethereum layer two scaling network Arbitrum, making for an efficient and reliable process. Once converted, the USDC can be stored in multiple fiat currencies, including USD, EUR and CHF, enabling seamless utilization in various transactions and expenses. Enabling Swiss bank account accessOne of the standout aspects of this initiative is the opportunity for users to establish individually owned, fully compliant bank accounts directly within the SafePal mobile wallet app. By completing the necessary know-your-customer (KYC) and onboarding procedures through Fiat24. Opening such bank accounts will be free, with no account creation or annual management fees being applied. However, transfer and deposit fees will be applied starting from a base rate of 0.6%. The project believes that the integration of NFT technology on Arbitrum will ensure the security and transparency of all related transactions. Veronica Wong, CEO and co-founder of SafePal, emphasized the importance of addressing the accessibility challenges faced by crypto users in a communication with CoinDesk. She highlighted the significance of providing a crypto-friendly banking experience that eliminates the hurdles imposed by traditional financial institutions. Additional payment platform partnershipsIn addition to the crypto Visa cards, SafePal has forged partnerships with leading payment platforms such as Paypal, Google Pay, Apple Pay and Samsung Pay, expanding the usability and convenience of its services. While the Visa card will initially be available in select European regions, plans are underway for its gradual expansion across the continent. Similarly, the in-app banking gateway will cater to users outside the United States and in non-U.S. sanctioned countries, fostering greater accessibility on a global scale. Working towards market growth through a partnership strategy is a route that SafePal has taken in the past. In May 2023 the company attempted to make further inroads into the Korean market by partnering with South Korean enterprise blockchain project Klaytn. In that instance, the wallet provider added support for digital assets that run on the Klaytn network via its mobile app, hardware wallet and browser extension-based wallet. In light of these developments, SafePal's SFP tokens have experienced a modest increase in value. At the time of writing, the token unit price stood at $0.8026, representing a 4.62% increase over the course of the past 24 hours.

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.
