釣魚攻擊的最新趨勢

釣魚攻擊一直是資安中最常見的威脅之一，隨著技術的進步令網路安全措施不斷加強，但釣魚攻擊的手段和策略也相對地不斷演變。了解這些最新趨勢和相應的防範策略對於保護個人和企業的資料安全至關重要。

首先，隨著智能設備的普及，攻擊者開始利用多個平台（如社交媒體、電子郵件、即時通訊應用等）進行協調攻擊。這種跨平台的釣魚攻擊可以在多個接觸點收集受害者的信息，增加誘餌的說服力。其次，利用AI生成的音頻或視頻模仿高層管理人員或親密關係者的語音、面貌，從而誘使受害者透露敏感信息或進行金融交易。再來是攻擊者常常利用時事新聞例如全球疫情、自然災害或政治事件作為釣魚的話題，這種時效性的話題使得釣魚郵件看起來更加真實，增加了攻擊的成功率。最後，攻擊者通過收集目標的個人信息（如工作、興趣、社交關係等），設計看似合理且高度個性化的訊息，使釣魚攻擊更難以識別。

面對各種最新的釣魚攻擊，企業或者個人都需要有相應的防範策略才能最大化降低攻擊的成功率或者損失。首先，定期對員工進行安全意識培訓，教育他們識別釣魚郵件的常見標誌，如拼寫錯誤、格式不一、非預期的附件或鏈接等。同時，定期舉辦模擬釣魚試驗，增強員工的實戰經驗。其次，強化登入過程，例如多因素認證，令攻擊者即使釣魚攻擊成功盜取了密碼，也因多重認證的存在而難以進一步侵入系統。再來是使用高級郵件過濾工具，郵件過濾工具可以大幅降低惡意郵件的到達率，進一步配置DMARC（Domain-based Message Authentication, Reporting & Conformance）協議可以幫助識別偽造的發件人。然後，確保所有系統和應用都是最新的，及時修補已知的安全漏洞，減少攻擊者可利用的入口。接著，使用安全擴展和插件來識別和阻止惡意網站。設置瀏覽器以阻止未經請求的彈出窗口和限制JavaScript的無限制執行，這些都能減少釣魚攻擊的成功率。然後，透過定期的安全審計來檢查和評估組織的安全措施和流程，確保它們能有效抵抗釣魚和其他類型的攻擊。最後，即使采取了所有預防措施，釣魚攻擊仍有可能成功。因此，企業應制定詳細的應急響應計劃，以便在資料泄露或其他安全事件發生時，能迅速反應並最小化損失。

釣魚攻擊的形式和技術持續進化，而這要求個人和企業必須不斷更新其安全措施和策略。通過教育培訓、技術防護和策略實施等多方面的努力，可以顯著減少這些攻擊的影響。正如俗語所說「知己知彼，百戰不殆」，在信息安全的世界中，持續的學習和適應是保護自己不受黑客攻擊的最好方式。

Leveraging OutSystems' rapid development strengths, our team achieves true Agile development, focusing intensely on user requirements. However, requirements are never fixed; they take time to refine within the project's cycle. If a developer simply builds projects based on the initial requirements, it leads to significant rework when those requirements are inevitably revised. This creates serious technical debt that can derail a project's schedule. To combat this, we strictly follow the OutSystems Canvas Design architecture to define each module's usage and content. We generalize logic into foundational modules, optimizing reusability and providing high adaptability when requirements change. This approach allows us to eliminate complicated dependencies—avoiding the deployment nightmares that plague monolithic systems. The Real-World Challenge: "The Spaghetti Monolith" We’ve all seen it. A project starts fast. The "Idea-to-App" time is record-breaking. But as sprints pass and requirements evolve, the "interest rate" on technical debt spikes. Suddenly, changing a simple UI element breaks a core business process because the logic was trapped inside the screen. Deployment becomes a "big bang" event where everything must go live at once because of circular dependencies. In our team, we don't just "code fast"; we architect for resilience. Our Solution: The 4 Layer Canvas Strategy We treat the 4 Layer Canvas not just as a suggestion, but as our structural imperative. Here is how we use it to handle volatile requirements:  Isolating Volatility (End-User Layer): We keep our User Interfaces (UI) and interaction logic in the End-User Layer. This layer is highly volatile—it changes constantly based on user feedback. By isolating it, we can redesign a "Customer Portal" without risking regressions in our core business rules.Stabilizing Business Logic (Core Layer): We abstract our entities and business rules into the Core Layer. This is the backbone of our factory. Whether the data is accessed by a Mobile App, a Web Portal, or a Timer, the validation rules remain consistent. This promotes the "Don't Repeat Yourself" (DRY) principle.Enabling Independent Deployments: By using Service Actions (Weak Dependencies) in our Core layer, we decouple our modules. This allows different squads to deploy changes independently without forcing a factory-wide refresh—a critical enabler for our CI/CD pipelines.The Governor: AI-Driven Architecture How do we ensure we stick to these rules when moving at Agile speeds? We don't just rely on manual code reviews; we use the AI Mentor System. This tool acts as our automated architect. It scans our entire factory to detect architectural violations that humans might miss, such as: Upward References: Preventing foundational libraries from depending on business logic.Side References: Ensuring our End-User apps don't tightly couple with one another.Circular Dependencies: Identifying the "deadly embrace" between modules that locks deployments.The AI Mentor System quantifies this debt, allowing us to pay it down proactively before it hinders our release velocity. Join a Team That Values Architecture In our Taiwan office, we believe that low-code doesn't mean "low-architecture." We are building resilient, composable enterprise ecosystems that can scale. If you are a developer who cares about structural integrity, clean code, and mastering the art of OutSystems architecture, we want to hear from you.

Does the following screenshot look familiar to you? Calendar invites that seem to appear out of nowhere in Microsoft Teams or Outlook, asking you to “review important information” or “resolve an account issue”?A phishing campaign has been found abusing Microsoft Teams calendar invites to deliver malicious links and files directly onto users’ calendars. These events often mimic Microsoft notifications, come from odd or external addresses, and include attachments such as .htm or .js files that, when opened, they can lead to credential theft, malware installation or even full remote access for the attacker.With phishing tactics evolving so quickly, ongoing awareness training remains critical and essential. Effective programs use realistic phishing simulations combined with targeted training to help employees recognize and report suspicious emails quickly, turning them into an active detection layer alongside your technical controls.At Ringus, we offer phishing simulation assessment services, with the following key features:💫Tailor-made realistic phishing templates💫Flexible campaign duration and cadence💫Comprehensive reporting and analytics with insights
