Crypto vulnerability uncovered with $1B in digital asset exposureSecurity vulnerabilities in the validator infrastructure of InfStones, an established infrastructure provider, have been disclosed by Tel Aviv-headquartered cybersecurity firm dWallet Labs.Photo by Brett Jordan on UnsplashBlockchain network validator vulnerabilityIn a detailed Medium blog post published on Tuesday, dWallet Labs shed light on a series of vulnerabilities that, when exploited, could potentially allow attackers to gain full control, execute code and extract private keys from numerous validators on major blockchain networks. Cryptocurrencies such as ETH, BNB, SUI, APT and others were identified as at risk, with potential direct losses estimated to exceed one billion dollars.The vulnerabilities discovered by dWallet Labs opened the door for attackers to compromise the private keys of validators across multiple blockchain networks, putting over one billion dollars of staked assets at risk. In response to the findings, InfStones, a Web3 infrastructure platform, also released a statement on Tuesday acknowledging the potential threat. However, its representative, Darko Radunovic, disputed the figures provided by dWallet Labs in a statement sent to Cointelegraph. Radunovic stated that the vulnerabilities identified in the production environment account for below 0.1% of their active nodes launched to date, emphasizing that the impact would be limited to a small fraction of their operational nodes.According to InfStones, “237 instances were in scope, of which 212 instances were deployed for our development and testing purposes, and 25 freshly deployed instances in the production environment.”Mitigating steps takenThe company detailed the immediate actions taken to mitigate the vulnerabilities, including shutting down the affected ports, as well as rotating all credentials and keys within their platform. An internal review conducted by InfStones revealed no additional adverse effects. Notwithstanding that, the company took the additional step of hiring an external security firm to audit its systems and policies.Meanwhile, dWallet Labs Founder and CEO Omer Sadika shared his thoughts on the X platform as to how he believes such events should be handled. Sadika wrote:”The worst way to handle a cybersecurity vulnerability is not taking responsibility and lying. We were super open and transparent with the goal of eliminating the risk to web3. My take: it’s not about whether you are fully secure or not, because no one is, it’s about how you handle it and maintain the trust with your partners and customers.”The collaboration between dWallet Labs and InfStones sheds light on the ongoing challenges faced by the cryptocurrency industry in maintaining the security and integrity of blockchain networks. While vulnerabilities were identified and addressed, the incident underscores the importance of proactive security measures to safeguard the assets and data within the rapidly evolving landscape of digital assets.

The South Korean government and the ruling party may postpone agreement on a unified proposal for the Digital Asset Basic Act, legislation that would include regulations on stablecoins. The bill represents the second phase of the country’s cryptocurrency regulatory framework, following the first phase that took effect in 2024 to strengthen investor protection.Photo by KS KYUNG on UnsplashAccording to Edaily, the two sides had planned a policy consultation on March 5 to finalize the draft. The meeting was later pushed back to this week but is now unlikely to take place, potentially delaying the government’s plan to complete stablecoin legislation by this month. The Digital Asset Basic Act is a comprehensive bill to regulate the crypto market, including issuance, distribution, disclosure, and listing of virtual assets. South Korea has more than 13 million crypto investors, and market participants see the legislation as a step toward reducing regulatory uncertainty. Meanwhile, the rapid rise of dollar-denominated stablecoins such as USDT and USDC has raised concerns that a slow regulatory response could undermine the country’s monetary sovereignty. Toss eyes dual role in KRW stablecoinsAmid ongoing debate over stablecoin regulation, Viva Republica, the operator of the payments app Toss, is preparing to move into the issuance and distribution of won-denominated stablecoins. At the 2026 Blockchain Meetup Conference last week, Seo Chang-whoon, corporate development director at Viva Republica, said Toss hopes to take on both roles in the stablecoin ecosystem, according to ZDNet Korea. “Toss would like to try serving both as a stablecoin issuer and as a distribution platform,” Seo said. The company is considering joining a consortium to issue a won-based stablecoin, which could include Toss, its financial affiliates, and traditional banks. Toss also plans to expand the token’s use through a dApp store, and indicated it may work with blockchain firms as it develops the business. Global firms are also studying the market potential for Korean won-backed stablecoins. DWF Ventures said in a report last week titled “South Korea’s KRW Stablecoin Opportunity” that a won-denominated stablecoin could offer meaningful benefits to domestic markets. The report argued that such a token could help reduce reliance on the U.S. dollar and curb capital outflows, while improving capital efficiency by allowing reserves to generate yield. With about 98% of South Koreans using digital payments, adoption could come quickly, the report said, adding that the system could also strengthen authorities’ ability to monitor and curb illegal activity. Survey finds modest optimism around BitcoinAmid growing expectations around stablecoin policy, a recent survey of South Korean crypto investors showed cautious optimism about Bitcoin’s price outlook this week. According to a weekly poll conducted last week by CoinNess and Cratos, 27.3% of respondents said they expect Bitcoin to rise or surge this week, up from 24% a week earlier. 32.2% predicted the price would move sideways, up from 28.1% the previous week, while 30.5% expected a decline or sharp drop, down from 47.9% a week earlier. When asked about market sentiment, 37% of respondents said they felt fear or extreme fear, while 32.2% described sentiment as neutral, and 30.8% said they were optimistic or extremely optimistic. Asked why they invest in cryptocurrencies, 33.9% of respondents said they see crypto as the only path to upward mobility. Another 32.5% cited confidence in the long-term value of Bitcoin and blockchain technology, while 25.5% pointed to its role as a hedge against instability in traditional finance. The remaining 8.1% cited volatility and 24/7 trading. According to CoinMarketCap data, Bitcoin was trading at $72,634.39 at the time of writing, up 9.34% over the past week. 

Overseas Crypto Holdings Declared to Korean Tax Agency Amount to $98BIn a recent press release from the South Korean National Tax Service (NTS), it was revealed that this year, a record 5,419 Koreans declared overseas financial assets amounting to KRW 186.4 trillion. This is a notable jump from the previous year, marking a 38.1% rise in the number of declarants and an impressive 191.3% increase in the declared amount.Photo by Traxer on UnsplashRecord-breaking declarationsThese are the most significant figures reported since the 2011 inception of the overseas financial account reporting system, which requires Korean individuals and entities to disclose their foreign financial holdings, like savings, stocks, collective investment schemes, and derivatives, if their balance exceeds KRW 500 million.The NTS attributed the record-breaking figures to foreign crypto accounts, a new addition to this year’s overseas account declaration.Crypto’s dominanceVirtual assets comprised a staggering 70.2% of the total declared amount, overshadowing all other assets. 1,432 individuals and corporate entities reported crypto holdings amounting to KRW 130.8 trillion (approximately $98 billion).Decline in non-virtual assetsFor non-virtual asset accounts, including deposits, savings, and stocks, the reported figure stood at KRW 55.6 trillion, marking a year-on-year drop of KRW 8.4 trillion, or a 13.1% decline.Call for complianceIn the future, the NTS plans to leverage data shared between countries to rigorously check for potential non-compliance in reporting overseas financial accounts. Those suspected of omissions can expect strict actions, including fines, criminal charges, public name disclosure, and the collection of related taxes.After the reporting deadline, filers may be eligible for a penalty reduction of up to 90%. Importantly, tax agencies worldwide, including the NTS, are gearing up to share information like cryptocurrency transaction details under the Crypto Asset Reporting Framework. In light of this, the NTS strongly encourages those who haven’t yet reported but are obligated to to promptly declare their overseas virtual asset accounts.
