Digital wallet D’CENT and Astar Network team up to bring scalable wallet services to users

Mixin Network Suspends Services Amid $200 Million HackOn Monday, Mixin Network, a decentralized peer-to-peer network whose project team is based in Hong Kong, officially confirmed a substantial security breach that resulted in the loss of approximately $200 million in crypto assets from its mainnet.Photo by GuerrillaBuzz on UnsplashSeptember 23 hackThis incident, disclosed via an X (formerly Twitter) post, prompted the immediate suspension of all deposit and withdrawal services on Mixin Network until further notice.The project team outlined that the hack occurred on September 23, exposing vulnerabilities that allowed malicious actors to compromise the database of a third-party cloud service provider. Mixin Network has taken action to address the situation, enlisting the expertise of Singapore-headquartered blockchain security investigator SlowMist and the support of Google to conduct a thorough investigation and formulate a recovery plan.At the time of the breach, Mixin Network’s holdings included $94.48 million in Ether, $23.55 million in Dai, and $23.3 million in Bitcoin, as reported in an independent investigation by PeckShield. The total value of assets affected amounted to $141.32 million.Cyvers, an Israeli Web3 security firm, has also been looking into the matter on Monday. In a social media post, the firm stated:”Our internal investigation has uncovered suspicious funding transactions involving @MixinKernel hacker addresses. Two of hacker addresses received 51 $ETH from 0x1795F0eBDa5A836aE63F28CE546E72de069A8bd2 who was interacted with @HuobiGlobal and @binance.”The firm goes on to call on Binance and its CEO Changpeng Zhao (CZ) and Huobi to help identify the wallet address in question.Halting withdrawalsIn response to the security breach, Mixin Network has temporarily halted all deposits and withdrawals on its platform. These services will only resume once the vulnerabilities have been identified and fully resolved. On X, the project stated:”Deposit and withdrawal services on Mixin Network have been temporarily suspended. After discussion and consensus among all nodes, these services will be reopened once the vulnerabilities are confirmed and fixed. During this period, transfers are not affected.”Details regarding the plans to recover the lost assets for affected users have yet to be announced.Despite initial promises that Mixin Network’s Founder, Feng Xiaodong, would address the incident in a public Mandarin live stream on September 25, links to the live stream were not provided on the official social media channels or the website mixin.network.The incident has garnered criticism on the basis of a lack of decentralization. One commentator stated:”Some of those blockchain protocols are so decentralized that when their cloud database is hacked, coins are also gone.”Ongoing hacksThis security breach on Mixin Network is the latest in a series of high-profile crypto-related incidents. Ethereum Co-Founder Vitalik Buterin recently fell victim to a SIM swap attack, which resulted in the compromise of his X (formerly Twitter) account.In a statement, Buterin revealed that the hackers had successfully executed a SIM swap, a type of attack that targets the victim’s mobile phone number to gain unauthorized access to various online accounts, including social media, banking, and cryptocurrency platforms.The repercussions of the Mixin Network hack underscore the ongoing challenges faced by the crypto industry in ensuring the security and protection of digital assets. As investigations continue, affected users await further developments and the eventual resumption of deposit and withdrawal services.

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 U.S. Securities and Exchange Commission (SEC) approved the spot bitcoin exchange-traded fund (ETF) last Tuesday, prompting South Korean investors to flock to cryptocurrency exchanges to make transactions. However, the revenues recorded by these exchanges showed a mixed performance in response to this development due to their differing transaction fee policies, according to local news outlet DealSite on Monday.Photo by Maxim Hopman on UnsplashTrading volumes surge and retreatAccording to crypto analytics platform CoinGecko, as of 9 a.m. on Jan. 12 (KST), Upbit's trading volume on Dec. 11 and 12 was approximately $5.1 billion and $6.1 billion, respectively, for a total of about $11 billion. During the same period, Bithumb recorded $2.6 billion and $2.4 billion, respectively, totaling nearly $5 billion. However, as of this writing at 11 a.m. on Jan. 15, Upbit’s 24-hour trading volume has dropped back down to $2.1 billion and Bithumb to $874 million. "After the SEC's approval, crypto exchanges were simultaneously flooded with transactions," an anonymous industry employee commented. "Bitcoin and Ethereum were mainly traded." Fee divergenceAlthough the ETF approval caused a general uptick in trading volumes, the amount of revenue that the exchanges earned from transaction fees varied. Upbit charges a fee of 0.05% for both buying and selling crypto, meaning the exchange made an estimated KRW 14.8 billion in revenue from the fees from Dec. 11 to 12. Bithumb, on the other hand, hasn't earned any revenue from trading fees since its zero-fee policy was implemented in October last year.  Bithumb had previously charged 0.25% for transactions and 0.04% with coupons. By implementing the former, the exchange lost about KRW 15.8 billion ($12 million) in revenue, and with the latter, it lost about KRW 2.5 billion. For crypto investors, Bithumb's zero-fee policy has made investing more accessible, but the exchange is unlikely to reap its own rewards. Significant investor interestMoreover, with trading for the spot bitcoin ETF beginning on the 11th, the influx of funds is expected to boost trading. "All told there were 700,000 individual trades today in and out of the 11 spot ETFs," Bloomberg ETF analyst Eric Balchunas told X (formerly Twitter). "For context, that is double the number of trades for $QQQ." $QQQ refers to the Invesco QQQ ETF. According to an image that accompanied Balchunas’ post, the total trading volume across all 11 spot ETFs was reportedly $4.3 billion. Grayscale's GBTC had the highest volume at $2.1 billion, followed by BlackRock’s IBIT at $1 billion and Fidelity’s FBTC at $673 million.
