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 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.

Circle and SBI Holdings join forces to propel USDC growth in Japan

Circle and SBI Holdings join forces to propel USDC growth in JapanIn a move aimed at advancing the adoption of the USD Coin (USDC) in the Japanese market, stablecoin issuer Circle and Japanese financial behemoth SBI Holdings have entered into a memorandum of understanding (MOU).Photo by Alex Knight on UnsplashBanking and distributionThe collaboration, outlined in a press release published on Monday, seeks to enhance the circulation of USDC, establish a robust banking relationship and broaden the footprint of Circle in the Asian nation.Key subsidiaries of SBI Holdings are set to play pivotal roles in this strategic partnership. SBI’s VC Trade Limited, among others, will actively engage by applying for licensing as an electronic payment instruments service, facilitating the distribution of USDC across Japan. Notably, this move aligns with efforts to propel the electronic payment ecosystem in the country.Further solidifying the collaboration, SBI’s Shinsei Bank will provide crucial banking services that empower access to USDC and enhance liquidity for businesses and users based in Japan. This initiative not only promotes the widespread usage of USDC but also establishes a secure financial infrastructure for its seamless integration into the Japanese market.Web3 service offeringAs part of this collaboration, the SBI Group plans to incorporate Circle’s Web3 Services solutions, encompassing programmable wallets, blockchain infrastructure and smart contract management tools.Circle has been busy in recent weeks, rolling out partnerships in the Asian region that will see greater use of its Web3 Services suite. In Taiwan, it partnered with a convenience store chain recently, in a move that will integrate its Web3 services into the Taiwan FamilyMart app. A similar deal was struck in September with Grab, a Southeast Asian multifaceted super-app.Jeremy Allaire, CEO of Circle, expressed the groundbreaking nature of this partnership, envisioning USDC as a stablecoin that can be extensively utilized in Japan’s burgeoning on-chain economy across various consumer-led Web3 product categories.Allaire had signaled an interest in delving further into the Japanese market back in July. Then, he suggested that the company might consider launching a stablecoin in Japan but that it was also interested in exploring partnerships in the East Asian country.Yoshitaka Kitao, CEO of SBI Holdings, commended Japanese authorities for creating a regulatory environment conducive to the adoption of stablecoins within the region. In June, Japan passed legislation mandating that stablecoins must be fully backed by highly liquid cash and cash-equivalent assets, preventing a recurrence of issues experienced by certain stablecoins.SBI’s digital asset involvementWhile Circle has very much been advancing its service offering in the Asian region in 2023, likewise SBI has been delving further into the realm of digital assets and Web3. In April it led a funding round into Standard Chartered subsidiary company Zodia Custody, a digital asset custodian. SBI has also invested in Zodia Markets, an exchange and brokerage platform which is also a Standard Chartered subsidiary company.SBI Holdings established the Osaka Digital Exchange (ODX) in 2021, a crypto exchange business which will commence security token trading next month. In a social media post on the X platform, Allaire highlighted SBI’s involvement in the digital assets space:“Importantly, Kitao-san is not a ‘johnny come lately’ to crypto and blockchain tech. He has understood it and invested in it for nearly a decade. SBI Holdings already operates digital asset trading, brokerage and cross-border payments solutions.”

Japan reclassifies crypto as financial products, paving way for lower taxes and ETFs

Japan's parliament passed landmark legislation on July 15 reclassifying cryptocurrencies as financial products under the Financial Instruments and Exchange Act, removing them from the Payment Services Act framework that had treated them as a means of settlement. According to CoinPost, the reform introduces insider-trading rules to the sector for the first time, raises penalties for unregistered dealing, and clears the way for domestic crypto ETFs. Under the changes, crypto exchange operators will be redesignated as "crypto asset trading businesses," and unregistered sales will carry prison terms of up to 10 years and fines of up to 10 million yen ($61,000), up from three years and 3 million yen. Gains will move from comprehensive taxation (where combined income and residence taxes can reach 55%) to a separate flat tax of around 20%, with losses eligible for a three-year carryforward, though those tax measures take effect only once the amended law is in force. If enforcement falls in fiscal 2027, the new rate would apply from Jan. 1, 2028.Photo by Kanchanara on UnsplashWeak yen drives crypto adoptionThe overhaul lands as Japanese companies increasingly turn to cryptocurrency as a treasury asset, with the yen's prolonged weakness pushing them to diversify their cash strategies, SBI VC Trade, the crypto exchange arm of financial conglomerate SBI Holdings, said. The exchange said it is seeing greater uptake of SBIVC for Prime, its service for corporate and large-lot clients, from companies looking to hold and use crypto. It is also fielding more business from listed firms that distribute Bitcoin (BTC) or XRP to shareholders through benefit programs, a practice the company said is spreading in Japan. The comments accompanied SBI VC Trade's announcement that its registered accounts topped 2 million as of July 6, double the 1 million it reported in 2025. The Tokyo-based firm attributed the growth in part to its April 2026 merger with fellow SBI Group exchange BitPoint Japan and to its stablecoin business. SBI VC Trade is Japan's only registered electronic payment instruments trading firm, the license category covering stablecoins. The company began offering USDC, the first U.S. dollar-denominated stablecoin available in Japan, in March 2025. In June 2026 it added JPYSC, which it describes as the country's first yen-denominated trust-type stablecoin, along with Ripple's dollar-pegged RLUSD, and launched a stablecoin lending service. The exchange plans to merge its two service brands around the end of December 2026. Separately, SBI Crypto, the group's mining unit, said it will shut down its mining pool on July 31. The pool will stop accepting mining shares at 7 a.m. Japan time, and the company urged customers to keep directing hashrate to the pool until the cutoff so that all eligible shares are included in the final payout. SBI Crypto said it has held discussions with other pool operators, some of which may offer preferential terms to migrating clients. Metaplanet expands into securitiesIn another sign of crypto's deepening ties with Japanese finance, Siiibo Securities, an online platform for privately placed corporate bonds, has changed its name to Metaplanet Securities after joining the Metaplanet group, the Tokyo-listed company known for its large BTC treasury. Siiibo, which holds a Type I financial instruments business license, said it plans to build a platform combining BTC and finance, developing products for retail investors that draw on its new parent's BTC management expertise while continuing to serve yield-seeking investors. Remixpoint discloses crypto yieldsListed energy and crypto firm Remixpoint, meanwhile, disclosed returns on its digital asset holdings as of the end of June. The company said it has earned a cumulative 9.95 BTC, worth roughly 108 million yen based on monthly average rates, from lending its BTC. Staking of altcoins has generated about 27.9 million yen in total, comprising roughly 10.1 million yen from ETH and 17.8 million yen from SOL, the company said, adding that it will continue building a financial structure that generates recurring income.
