CDN is like a global warehouse network, storing your website and application content on servers closest to users. When users visit your website or use your application, CDN will automatically connect them to the nearest server, significantly shortening the data transmission distance and improving access speed.&nbsp;<ad-banner-1></ad-banner-1>5 reasons to make your business embrace the magic of CDN:<ul><li>Speed engine, user experience instantly soars:</li></ul>CDN can distribute content to nodes closest to users, shortening the transmission distance and improving content transmission speed. This is essential for the user experience of websites and applications.According to Google research, for every 1 second a web page load time is reduced, conversion rate increases by 20%. This means that CDN can help businesses significantly improve conversion rates and keep users' hearts. Just imagine, who would be willing to wait for a slow-loading website?&nbsp;<ul><li>Cost killer, leapfrog improvement in operational efficiency:</li></ul>CDN can reduce bandwidth usage and lower operating costs. CDN will cache frequently used content to edge nodes, thereby reducing the load on the source server and reducing bandwidth usage. In addition, CDN can also improve server utilization and lower operating costs. According to Limelight Networks research, CDN can help businesses average up to 50% bandwidth cost reduction.&nbsp;<ul><li>An impregnable network fortress:</li></ul>DDoS attacks have always been a nightmare for businesses. DDoS attacks send a large amount of malicious traffic to the target server, causing the server to crash. CDN can use its distributed network architecture to resist DDoS attacks.CDN will distribute content to multiple nodes, thereby dispersing the impact of DDoS attacks. In addition, CDN can also use its intelligent scheduling technology to identify and block malicious traffic.&nbsp;<ul><li>SEO boost, darling of search engines:</li></ul>According to Google research, for every 1 second a web page load time is reduced, ranking increases by 5 places. And search engines, including Google, will prioritize fast-loading websites. Therefore, using CDN technology to accelerate can also improve your website's ranking in search results, and win the championship in the search engine arena!&nbsp;<ul><li>Crossing the network barrier, the Chinese market is no longer far away:</li></ul>For many businesses, the Chinese market is attractive, but strict internet censorship has also become an insurmountable barrier.

3 Steps to Safeguard Your Enterprise Network: A Guide to Tackling Cyber Vulnerabilities

企业网络漏洞攻略 定期做足安检3步曲

企業網絡漏洞攻略 定期做足安檢3步曲

Consultation on investment limit industry has counter-proposalsHong Kong is setting up a new regulatory regime for virtual asset retailing. The SFC earlier suggested that trading platform operators should assess the suitability of retail clients to participate in virtual asset trading, and set a cap on the investment amount for each client, which should be reviewed regularly. Some industry players and academics interviewed by Hong Kong Wen Wei Po worry that setting investment caps for retail investors will suppress the liquidity and scale of the market, which is not conducive to the development of the virtual asset industry, and that virtual assets can be graded according to the risk level by making reference to the investment grade of bonds, so that investors can invest according to their tolerance. Some countries such as Canada and Thailand have also imposed a certain degree of restriction on retail investors, reflecting the balanced attitude of global regulators towards virtual assets and their efforts to protect the safety of retail investors while developing the industry.As to whether there should be investment limits for retail investors in virtual assets, UD founder and veteran cryptocurrency investor Zhang Tao believes that this approach is not very meaningful, as the stricter the regulation, the more resistant investors will be, "The more money people have, the more options they want, and the better chance they have to invest elsewhere. He pointed out that traditional financial products have risk levels, the future of virtual asset products can be used in the current classification system, with trading platforms to KYC (know your customer), disclose the risk to customers, and assess their risk-taking ability, etc., sufficient to protect retail investors.Regulation focuses on education to increase investor knowledgeZhang Tao stressed that the focus of regulating the retail sale of foreign exchange is "education", "regulators cannot say on the one hand that foreign exchange is 'all evil' and on the other hand allow investors to participate. He believes that regulators should educate the public about blockchain, including related technologies and practices, as well as crypto assets and their risks, and so on. In the past few years, the government has been actively reminding the public about the risks of virtual assets. When the public is educated, only then will the availability of virtual funds become widespread, just like the development of the stock market in the 1970s and 1980s, when financial products and investments became widespread, can Hong Kong develop into an international financial center.Liu Jia, head of HashKey's legal department, believes that regulators should differentiate between retail and professional investors, and that investment categories can be different; however, she has a different view on whether the income percentage should be used as a cap. For example, it depends on whether the cryptocurrency is a "new" or "old" token, or whether it is a token that has been issued for months or even years and has a Track Record, so that the past performance of the token can be checked to see if it is stable. For example, whether the token has been issued for a long enough time, whether the price is stable, and how big the market capitalization is, etc. are all conditions that make the market or retail investors feel comfortable to invest.Liu Jia pointed out that usually assets with larger market capitalization and relatively stable operation are more suitable for retail customers. On the contrary, from the regulatory point of view, there will be more worries for newly issued tokens, and regulators may need to conduct more scrutiny and ask questions to the platforms offering such tokens for trading, or set additional thresholds for platforms to answer. However, she stressed that licensed exchanges certainly want to allow retail investors to participate in as many cryptocurrencies as possible in order to make a big push for the industry to thrive.Investment caps should not be one-size-fits-all and should depend on the nature of the investmentRather, it should depend on the nature of the cryptocurrency that retail investors are allowed to invest in, the nature and security of the asset, and the KYC of the exchange. In order to ensure that retail investors have sufficient net worth, sophisticated investment experience and knowledge, and are capable of taking risks, the "Eligible Crypto Investor" and "Accredited Crypto Investor", as well as the "Quoted Investment" and "Unquoted Investment" are established. Investment" and "Unquoted Investment" are the investment categories. &nbsp;<div class="raw-html-embed"><div style="text-align: center;">

谘询对投资设限额 业界有反建议香港正为虚拟资产零售建立全新监管制度，证监会早前建议，交易平台营运商应评估零售客户是否适合参与虚拟资产交易，并为每名客户设定投资金额上限，且定期检视。有业界人士和学者接受香港文汇报访问时担忧为散户设置投资上限会压抑市场流动性及规模，反而不利虚资行业发展，认为可参考债券的投资级别，按风险程度将虚拟资产分级，让投资者视承受能力进行投资。翻查资料，全球近年亦陆续推出全新法例和制度监管虚资交易，部分国家如加拿大和泰国亦对散户设立一定程度的限购，反映全球监管机构对虚拟资产的态度力求平衡，在发展行业同时，尽最大努力保障散户安全。就应否对虚资零售投资者设立投资限额，UD创办人及资深加密货币投资者章涛认为，这种做法意义不大，因为愈管得严，投资者愈抗拒，「钱愈多的人愈想多些选择，他们好大机会转到其他地方投资。」他指，现时传统金融产品都有风险级别，将来虚拟资产产品都可采用现时的分级制度，配合交易平台对客户进行KYC（认识你的客户）、向客户披露风险、并评估他们的风险承担能力等，足以保障散户投资者。监管重点是教育 增投资者知识章涛强调，监管虚资零售的重点是「教育」，「监管机构不能一方面说虚资是『万恶』，另一方面又容许投资者参与。」他认为，监管机构要教育公众认识区块链，包括相关技术和做法，以及认识加密资产和其风险等等，这些教育都要普及。过去几年，政府积极提醒公众有关虚资的风险，现时要发展香港成为国际虚拟资产中心，就应该平衡信息，教育公众虚资的本质是什么，让公众了解。当对公众的教育普及，虚资才能普及，正如七八十年代股市发展一样，金融产品和投资普及，香港才能发展成国际金融中心。HashKey法律部主管刘佳认为监管机构应该要区分零售和专业投资者，投资类别可以不同；但是否要以收入百分比做上限，她就对此就有不同看法。她认为，监管被纳入零售类别的虚拟资产时，应由资产本身出发，例如要视乎该加密货币是「新」抑或「旧」，是一个全新发行的代币；抑或是已经发行了好几个月甚至几年、拥有追踪纪录（Track Record）的代币，可以翻查到该代币的过往表现是否稳定。例如该代币的发行时间是否够长、价格是否稳定、市值有几大等等，都是令市场或散户可以放心投资的条件。刘佳指出，通常市值较大及相对运行较稳定的资产，都比较适合零售客户；反而从监管角度而言，全新发行的代币会有更多忧虑，监管机构可能需要向提供这类代币交易的平台进行更多审查和提问，或者设立额外门槛让平台解答。但她强调，持牌交易所当然希望可以让零售投资者参与的加密货币愈多愈好，以大力促进行业蓬勃发展。投资上限不应一刀切 应视乎性质DigiFinex Global首席财务官陈昱丞认为，投资高风险的加密货币，本身就需要敢于尝试，他认为政策不应「一刀切」，将所有加密货币的零售投资设上限或不设上限；而是要视乎允许散户投资的是哪种加密货币，根据该资产的性质和安全程度，再配合交易所对客户进行的KYC，以确保零售投资者拥有足够净资产、成熟的投资经验和知识，有足够能力承担风险，而制定「合格加密货币投资者（Eligible Crypto Investor）」和「认可加密货币投资者（Accredited Crypto Investor），以及「报价投资（Quoted Investment）」和「未报价投资（Unquoted Investment）等等投资类别。 &nbsp;<div class="raw-html-embed"><div style="text-align: center;">

</div> As blockchain technology becomes more ubiquitous in various industries, it is essential to ensure its security. Blockchain offers unparalleled transparency, decentralization, and immutability, making it a potent tool for securing sensitive data. However, like any technology, it is not immune to security threats. In this article, we will explore ten critical considerations for ensuring blockchain security.1. Encryption: Encryption is the foundation of blockchain security. All data stored on a blockchain network is encrypted using complex cryptographic algorithms, making it impossible for hackers to access and manipulate it. It is crucial to use the latest encryption protocols to prevent breaches.<ad-banner-1></ad-banner-1>2. Private keys: Private keys are critical to blockchain security. They are unique codes that allow users to access their blockchain accounts. Users must keep their private keys safe and secure, preferably in cold storage, to prevent theft or unauthorized access.3. Consensus protocols: Consensus protocols are essential for ensuring the integrity and security of the blockchain network. They prevent malicious actors from manipulating data and ensure that all transactions are valid. The most commonly used consensus protocols are Proof of Work (PoW), Proof of Stake (PoS), and Delegated Proof of Stake (DPoS).4. Immutable ledger: Blockchain's immutability makes it an excellent tool for securing sensitive data. Once data is stored on the blockchain, it cannot be altered, deleted, or tampered with. This feature makes it an ideal solution for storing financial data, medical records, and other sensitive information.5. Network security: Blockchain networks must be secured to prevent unauthorized access and manipulation. It is crucial to use firewalls, intrusion detection and prevention systems, and other security measures to protect the network from cyber threats.6. Smart contract security: Smart contracts are self-executing programs that run on the blockchain network. They are used to automate various processes and transactions. It is essential to ensure that smart contracts are secure and free from vulnerabilities, as they can lead to significant financial losses if exploited.7. Token security: Tokens are digital assets that are used to represent value on the blockchain network. They must be secured using encryption and other security measures to prevent theft or unauthorized access.8. Compliance: Compliance is essential for ensuring blockchain security. Blockchain networks must comply with relevant regulations, such as KYC (Know Your Customer) and AML (Anti-Money Laundering), to prevent fraudulent activities.9. Risk assessment: Risk assessment is crucial for identifying potential security threats and vulnerabilities. Conducting regular risk assessments and implementing appropriate security measures to mitigate risks is essential.10. Ongoing monitoring and testing: Blockchain security is an ongoing process. It is crucial to monitor the network continuously and conduct regular penetration testing to identify and fix security vulnerabilities.Blockchain's potential to transform industries is immense, but security is crucial. The ten tips we've shared for securing blockchains are just the start. As tech advances, so do risks, so stay updated on security protocols to keep data safe.As the famed cybersecurity expert, Bruce Schneier said, "Security is a process, not a product." By following these critical considerations and implementing appropriate security measures, we can ensure that blockchain technology remains a secure and trusted tool for securing sensitive data. &nbsp;<div class="raw-html-embed"><a href="https://www.ud.hk/blockchain-security-solutions" data-cta="UDHub" style="width: 320px;height: 50px;display: block; background: #2A3795; color: #ffffff; text-decoration:none; line-height:50px; text-align:center; font-family: Arial; font-weight:bold;border-radius: 3px;margin:20px auto">Explore Blockchain Security with UD</a></div><div class="raw-html-embed"><a href="https://www.ud.hk/enquiry?enquiryType=product&amp;productCategory=blockchainSecurity&amp;productName=Blockchain%20Security%20Solutions&amp;customSubject=%5BUD%20Blockchain%20Consultation%5D%20%5B%E7%AB%8B%E5%8D%B3%E8%AB%AE%E8%A9%A2%5D&amp;customTitle=UD%20Blockchain%20Security%20Solutions" data-cta="UDHub" style="width: 320px;height: 50px;display: block; background: #28AA2E; color: #ffffff; text-decoration:none; line-height:50px; text-align:center; font-family: Arial; font-weight:bold;border-radius: 3px;margin:20px auto">Enquiry Now</a></div> &nbsp;

</div>AbstractI. The rise and crisis of DEXs<ad-banner-1></ad-banner-1>II. Types of DEXs smart contract vulnerabilitiesIII. Importance of smart contract audits for DEXsIV. Hot to conduct a smart contract audit for a DEX &nbsp;The rise and crisis of DEXsDEXs are popular because they offer a decentralized and trustless way to trade digital assets without intermediaries. However, with popularity comes the risk of cyber attacks, resulting in significant financial losses for DEX operators and users. Smart contract audits can identify and mitigate vulnerabilities that hackers could exploit.<h2>Types of DEXs smart contract vulnerabilities</h2>Like any other technology, DEXs are not immune to vulnerabilities, especially in their smart contracts. Here are different types of DEX smart contract vulnerabilities that traders and developers should be aware of. &nbsp;Reentrancy Attacks One of the most common smart contract vulnerabilities is the reentrancy attack. This type of attack occurs when a malicious actor exploits a flaw in the smart contract code to call the same function repeatedly before the previous call has completed, thereby draining funds from the contract. Many DEXs have fallen prey to reentrancy attacks, resulting in significant losses for traders.Front-Running Attacks Front-running attacks are another type of DEX smart contract vulnerability. In this type of attack, a miner or validator observes a pending transaction and executes a similar transaction with a higher gas fee, allowing them to profit at the expense of the original trader. This type of attack is particularly prevalent in DEXs that use order books.Oracle Manipulation DEXs rely on oracles to obtain real-time pricing data for cryptocurrencies. However, if these oracles are manipulated or compromised, the entire DEX can be affected. Hackers can manipulate the oracle to provide false pricing data, leading to incorrect trades and losses for traders. Insufficient Input Validation Smart contracts that are not properly validated can be vulnerable to attacks. Hackers can exploit these vulnerabilities by injecting malicious code into the contract, which can lead to various types of attacks, including stealing funds or disrupting the DEX's functionality.Contract Upgradeability Some DEXs may include upgradeable smart contracts that allow developers to make changes to the code without requiring a hard fork. However, this feature can also be exploited by malicious actors to introduce vulnerabilities or steal funds from the contract. Importance of smart contract audits for DEXsSmart contracts are the backbone of DEXs, and any vulnerability in the code can potentially lead to severe consequences for users, including the loss of funds. That's why smart contract audits are essential for DEXs to ensure that their code is secure and free from any vulnerabilities.&nbsp;A smart contract audit is a process that involves a thorough review of the code by a third-party auditor who has expertise in smart contract development and security. The auditor examines the code for potential bugs, exploits, and vulnerabilities and provides recommendations for improving the code's security.Smart contract audits are crucial for DEXs for several reasons:Security: Smart contract audits can detect and prevent potential security vulnerabilities in DEXs. Auditors can identify any weaknesses in the code and provide recommendations for remediation, helping to protect users and assets from potential hacks.Compliance: Smart contract audits can help DEXs ensure that their code is compliant with regulatory requirements. Auditors can review the code to ensure that it meets legal standards and requirements, helping DEXs to avoid legal and financial penalties.Reputation: Smart contract audits can help DEXs build a reputation for trustworthiness and reliability. Audits provide assurance to users that the DEX is safe to use and that their funds are secure.Innovation: Smart contract audits can help DEXs innovate and improve their code. Auditors can provide recommendations for improving the code's efficiency, scalability, and functionality, enhancing the user experience and driving growth.<h2>How to conduct a smart contract audit for a DEX</h2>Step 1: Understand the DEX's smart contractThe first step in conducting a smart contract audit is to understand the DEX's smart contract. This involves analyzing the code to identify any potential vulnerabilities, such as coding errors, logical flaws, or security loopholes. You should also review the DEX's whitepaper to gain a deeper understanding of the platform's functionality and any security measures that have been implemented.Step 2: Identify potential attack vectorsOnce you have a good understanding of the DEX's smart contract, you should identify potential attack vectors. These are areas of the code that could be exploited by attackers to gain unauthorized access or control over the DEX's assets. Some common attack vectors for DEXs include front-running, flash loans, and price manipulation.Step 3: Review the DEX's security measuresAfter identifying potential attack vectors, you should review the DEX's security measures. This includes analyzing the smart contract's access control mechanisms, transaction validation procedures, and error handling processes. You should also review the DEX's security infrastructure, such as its use of encryption, firewalls, and other security measures.Step 4: Test the smart contractAfter conducting a thorough review of the DEX's smart contract and security measures, it's time to test the code. This involves running various scenarios and simulations to identify any vulnerabilities or weaknesses in the code. You should also test the smart contract's interactions with other smart contracts and external systems to ensure that they are secure.Step 5: Provide recommendations and remediationFinally, after completing the audit, you should provide recommendations and remediation to the DEX's development team. These recommendations should be based on the findings of the audit and should aim to address any vulnerabilities or weaknesses that were identified. You should also provide guidance on how to implement the recommended changes and ensure that the DEX's security measures are up to par. &nbsp;In conclusion, conducting a smart contract audit for a DEX is a critical step in ensuring the security and trustworthiness of the platform.&nbsp;UD Blockchain offers thorough smart contract audit services.

DEXs 智能合約漏洞的種類<ad-banner-1></ad-banner-1>III. 智能合約審計對於 DEXs 的重要性IV. 如何為 DEXs 進行智能合約審計？ &nbsp;<h2>DEXs 的興起及危機</h2>DEX 愈來愈受歡迎，因為它們提供一種去中心化和無需中介的方式來交易數字資產。然而，隨著其受歡迎程度增加，也帶來了遭受網絡攻擊的風險，這可能導致 DEX 經營者和用戶的巨大財務損失。智能合約審計可以發現和減輕黑客可能利用的漏洞。 &nbsp;DEXs 智能合約漏洞的種類和任何其他技術一樣，DEX 並不免於漏洞，特別是在其智能合約中。以下是交易者和開發人員應該注意的不同類型的 DEX 智能合約漏洞。重入攻擊（Reentrancy Attacks） 最常見的智能合約漏洞之一是重入攻擊。這種攻擊發生在惡意行為者利用智能合約代碼中的漏洞，在前次調用完成之前重複調用同一函數，從而從合約中提取資金。許多 DEX 都曾遭受過重入攻擊，導致交易者遭受巨大損失。搶先攻擊（Front-Running Attacks） 搶先攻擊是另一種 DEX 智能合約漏洞。在這種攻擊中，礦工或驗證人觀察到待定交易並執行一筆相似的交易，並支付更高的燃氣費，從而讓他們從原始交易者的損失中獲利。此類攻擊在使用訂單簿的 DEX 中特別普遍。Oracle 資料篡改（Oracle Manipulation） DEX 依賴 Oracle 獲取加密貨幣的實時定價數據。然而，如果這些 Oracle 受到篡改或被入侵，整個 DEX 可能受到影響。黑客可以操縱 Oracle 提供虛假的定價數據，導致交易錯誤和交易者的損失。 &nbsp; 輸入驗證不充分（Insufficient Input Validation） 未經充分驗證的智能合約可能容易受到攻擊。黑客可以利用這些漏洞注入惡意代碼到合約中，這可能導致各種類型的攻擊，包括盜取資金或破壞 DEX 的功能。合約升級性（Contract Upgradeability） 某些 DEX 可能包括可升級的智能合約，允許開發人員在不需要硬分叉的情況下對代碼進行更改。然而，這個功能也可能被惡意行為者利用，引入漏洞或從合約中盜取資金。 &nbsp;<h2>智能合約審計對於 DEXs 的重要性</h2>智能合約是 DEX 的基礎，代碼中的任何漏洞都可能對用戶產生嚴重後果，包括資金損失。這就是為什麼智能合約審計對於 DEX 非常重要，以確保其代碼安全且沒有任何漏洞。 智能合約審計是一個過程，其中第三方審計師對代碼進行全面審查，具有智能合約開發和安全方面的專業知識。審計師會檢查可能存在的錯誤、漏洞和弱點，並提供提高代碼安全性的建議。 智能合約審計對於 DEX 非常重要，原因如下：安全性：智能合約審計可以發現和防止 DEX 可能存在的安全漏洞。審計師可以識別代碼中的任何弱點，並提供修復建議，有助於保護用戶和資產免受潛在的黑客攻擊。合規性：智能合約審計可以幫助 DEX 確保其代碼符合監管要求。審計師可以檢查代碼是否符合法律標準和要求，幫助 DEX 避免法律和財務懲罰。聲譽：智能合約審計可以幫助 DEX 建立可信度和可靠性。審計提供了向用戶保證 DEX 安全可靠的保證。創新：智能合約審計可以幫助 DEX 創新和改進其代碼。審計師可以提供提高代碼效率、可擴展性和功能性的建議，增強用戶體驗並推動增長。 &nbsp;<h2>如何為 DEXs 進行智能合約審計？</h2>進行智能合約審計需要專業知識和經驗，因此尋找一家可靠的審計公司是至關重要的。以下是 DEX 進行智能合約審計的步驟：步驟1：選擇審計公司尋找一家具有豐富經驗和專業知識的審計公司。審計公司應該具有對智能合約開發和安全方面的深入了解。 步驟2：確定審計範圍與審計公司合作，確定要審計的範圍，包括代碼的哪些部分以及需要審計的時間範圍。步驟3：進行審計審計師將對代碼進行全面審查，檢查可能存在的錯誤、漏洞和弱點，並提供提高代碼安全性的建議。&nbsp;步驟4：提供報告審計公司將提供審計報告，詳細說明代碼的安全和4合規性狀況，並提供改進代碼的建議。&nbsp;步驟5：實施建議DEX 應根據審計報告中的建議進行修復和更新代碼，以提高其安全性和合規性。 &nbsp;總而言之，為 DEX 進行智能合約審計是確保平台安全可靠的關鍵步驟。UD Blockchain 提供全面的智能合約審計服務。請聯繫我們的區塊鏈安全專家，現在就保護您的 DEX 用戶和資產。 &nbsp;<div class="raw-html-embed"><a href="https://www.ud.hk/tc" data-cta="UDHub" style="width: 320px;height: 50px;display: block; background: #2A3795; color: #ffffff; text-decoration:none; line-height:50px; text-align:center; font-family: Arial; font-weight:bold;border-radius: 3px;margin:20px auto">UD智能合約審計服務</a></div><div class="raw-html-embed"><a href="https://www.ud.hk/tc/enquiry?enquiryType=product&amp;productCategory=blockchainSecurity&amp;productName=%E5%8D%80%E5%A1%8A%E9%8F%88%E7%B6%B2%E7%B5%A1%E5%AE%89%E5%85%A8%E6%96%B9%E6%A1%88&amp;customSubject=%5BUD%20Blockchain%20Consultation%5D%20%5B%E7%AB%8B%E5%8D%B3%E8%AB%AE%E8%A9%A2%5D&amp;customTitle=UD%20%E5%8D%80%E5%A1%8A%E9%8F%88%E7%B6%B2%E7%B5%A1%E5%AE%89%E5%85%A8%E6%96%B9%E6%A1%88" data-cta="UDHub" style="width: 320px;height: 50px;display: block; background: #28AA2E; color: #ffffff; text-decoration:none; line-height:50px; text-align:center; font-family: Arial; font-weight:bold;border-radius: 3px;margin:20px auto">服務查詢</a></div> &nbsp;&nbsp; &nbsp;

</div>&nbsp;Security incidents in Hong Kong are on the uptrend. According to the data of the Hong Kong Security Watch Report (second quarter) from HKCERT, single network security incidents reached a 94% quarter-on-quarter increase.<ad-banner-1></ad-banner-1><figure class="image"><img src="https://static-asst.8338.hk/udhk-cms/2EAtJIFaYlR4LGjzDpES.png"></figure><figure class="image"><img src="https://static-asst.8338.hk/udhk-cms/RPZ9Z0Li8KXDJdcLPaO1.png"></figure>(Source : HKCERT) &nbsp;&nbsp;The number of websites involved in phishing attacks increased by 524% in this quarter, from 806 (first quarter) to 5,033 (second quarter).<figure class="image"><img src="https://static-asst.8338.hk/udhk-cms/MCCQIeHctksKhheK7gBu.png"></figure><figure class="image"><img src="https://static-asst.8338.hk/udhk-cms/4aUl4K9Li2h4v4lCORx3.png"></figure>(Source : HKCERT)&nbsp;According to HKCERT, the phishing attacks of banks and the Consumption Voucher Scheme are rising, and most phishing websites are using similar websites. They were set up by automated tools to attack in a short time. The most popular trick used by hackers were phishing attacks through SMS, by spreading fake websites (including counterfeiting websites, such as cryptocurrency exchange, DEX) to get victims’ personal information. Encountering frequent phishing attacks, UD recommends users paying attention to the following points when receiving email, SMS or social media hyperlinks to avoid being hacked!&nbsp;Find out three ways below to avoid cyber threats!&nbsp;1.
