Case Study: 20-Year Automated Defense Meets Unprecedented Week-Long Blitz — Viking Telecom Leverages AI to Perfectly Resolve DDoS Attack for a 13-Year Partner
Date: 15-Jun-2026 ~ 20-Jun2-2026
個案背景與罕見挑戰 (The Unprecedented Challenge) 今次遭遇網絡安全考驗的，是我們一位老朋友 – 自 2013 年起便與我們團隊合作、至今攜手走過 13 個年頭的知名香港主機商。
一般情況下，市場上的 DDoS 攻擊通常只會維持短時間。然而這一次，黑客採取了極其罕見的「拉鋸戰」策略：該客戶同一 IP 段內有超過 10 個重要 IP，遭到持續長達約 1 星期的密集式惡意攻擊，峰值流量高達 40-50Gbps。連續整整一星期、多點同時轟炸，這在我們多年的網絡運維生涯中確實極其罕見，甚至可以說是第一次面對如此嚴峻的極端情況。
Generally, DDoS attacks in the market are short-lived. However, this time, hackers adopted an exceptionally rare, persistent “war of attrition” strategy: over 10 critical IPs within the same subnet of our client were bombarded by a relentless, week-long malicious attack, with peak traffic reaching 40-50 Gbps. Facing a multi-point barrage that lasted a full week was an extremely rare anomaly in our decades of network operations—in fact, it was our very first time encountering such an extreme scenario.
二十年累積的常規防禦：秒級 Blackhole 自動化機制 (Our 20-Year Standard Defense: Second-Level Automated Blackholing) 其實，維京電訊的核心團隊自 2000 年（i4hk 時代）起經營香港網絡服務，早在二十多年前就已經部署了非常成熟的 Blackhole（黑洞路由）防禦機制。
這套自動化系統非常高效：能在短短數秒內精準偵測到攻擊並自動執行黑洞；最重要的是，在檢測到攻擊停止後的數分鐘內，系統就會自動解除黑洞，確保客戶珍貴的 3C 頂級直連路由（CN2, CUG, CMI）保持不變與最佳體驗。在過往一般情況下，這套機制都能完美且輕鬆地緩解絕大多數的常規短時間攻擊。
The core engineering team behind Viking Telecom has been managing Hong Kong network services since 2000 (the i4hk era) and deployed a highly mature automated Blackhole (Null Route) defense mechanism over twenty years ago.
This automated system is exceptionally efficient: it detects attacks and triggers blackholing within mere seconds. Crucially, within minutes after detecting that the attack has subsided, the system automatically clears the blackhole, ensuring the client’s premium 3C direct routing (CN2, CUG, CMI) remains completely unchanged and optimized. Under normal circumstances, this time-tested automation has perfectly and effortlessly mitigated 99% of conventional, short-lived attacks.
關鍵決策：當常規失效，2026 年 AI 實現了過去的「不可能」 (The Turning Point: How AI Made the Impossible Possible in 2026) 但這一次，面對連續一星期對 10 多個 IP 的日夜狂轟，如果繼續沿用 Blackhole 機制，等同於要客戶的 10 多個核心業務跟著停頓一整星期，這對主機商而言是無法承受的災難。
在以往的傳統網絡架構中，要在不拉黑洞的情況下正面吞下 50G 洪水、同時保住 3C 路由與本地延遲，是一件幾乎不可能完美兼顧的難題。幸好踏入 2026 年 AI 年代，以往技術上很難實現的彈性路由調度，現在都能使用 AI 一一完美實現。面對這次史無前例的危機，我們迅速為客戶啟動了最新 AI 智能防禦系統：
-
香港本地流量・堅守 1ms 直連：AI 在毫秒間精準識別並分離本地合法流量，將其保留在本地直連線路，維持 1ms 的極速極低延遲，本地用戶訪問絲毫不受干擾。
-
3C 及國際流量・自動化動態繞道清洗：AI 系統自動將受襲 10 多個 IP 的跨境與 3C 流量，無縫動態引流至海外頂級高防清洗中心。50G 的龐大垃圾流量在海外被洗淨後，乾淨的合法流量實時回注。
However, with more than 10 IPs under heavy, continuous fire for a whole week, relying on traditional blackholing would mean forcing the client’s core hosting business into a week-long blackout—a catastrophic scenario for any hosting provider.
In the past, neutralizing a 50G multi-point flood without blackholing while maintaining 3C routing and local latency was an almost impossible engineering balance. Thankfully, entering the 2026 AI era, complex dynamic mitigations that were once technologically out of reach can now be flawlessly realized one by one through AI. In response to this unprecedented crisis, we deployed our latest AI-Powered Defense System:
-
Hong Kong Local Traffic (1ms Direct Link): AI precisely identified and isolated local legitimate traffic within milliseconds, keeping it on our local direct lines to maintain an ultra-low 1ms latency.
-
3C & International Traffic (Automated Dynamic Overseas Scrubbing): The AI system automatically and seamlessly rerouted the affected IPs’ cross-border traffic to global high-defense scrubbing centers (such as the US). 50G of malicious traffic was filtered in the cloud, returning only “clean” data to the servers in real-time, preserving business continuity.
處理結果 (The Results) 在我們二十多年累積的務實基建儲備，以及 2026 最新 AI 智能防禦的完美配合下，我們成功克服了這場歷史性的挑戰！

面對連續一星期、10 多個 IP 同時受襲的極端情況，客戶主機服務全程保持在線，業務零停頓！
-
完美守住了主機商 13 年來建立的優良商譽，旗下無數企業網站安然度過危機。
Backed by our two decades of pragmatic infrastructure and the perfect execution of the latest 2026 AI smart defense, we successfully conquered this historic challenge:
-
Despite a week of intense, multi-point bombardment across 10+ IPs, the client’s hosting platform remained completely online with zero business interruption.
-
Their hard-earned 13-year reputation was fully safeguarded, with countless downstream enterprise websites navigating the crisis unscathed.
