美國對抗北韓大規模加密貨幣盜竊戰役揭秘




美國領頭圍堵北韓加密貨幣黑客 防範難過追討

北韓透過加密貨幣黑客活動已經搶劫接近50億美元,而單是今年就有超過20億美元被盜,當中包括一次針對ByBit交易所的15億美元大劫案。這個數字令人咋舌,但現實是,除了企業自己投資提升保安外,現階段可以預防未來攻擊的手段實在有限。

不過,值得安慰的是,北韓要將這些數碼戰利品兌換成現實可用的資金其實並不容易,這個過程通常需要經過「認識你的客戶」(KYC)驗證和銀行賬戶,對於一般人已經不易,更何況是北韓黑客。美國和其他國家正是針對這個環節加強打擊。

美國目前正建立一個更高階的追蹤和追回被盜加密資產的系統。據彭博報道,美國特勤局旗下的「全球調查行動中心」(GIOC)在過去十年已追回接近4億美元的被盜資產。雖然數字看似可觀,但相對北韓的搶劫規模,這只不過是滄海一粟。ByBit事件就反映出凍結加密資產的困難——黑客在事發兩星期內已成功提走數億美元。五個月過去,只凍結到5%,有62%已「無法追蹤」,換句話說,大約三分之一(約5億美元)仍有追回機會。

最近,部分ByBit被盜資產在希臘浮現出來,有關錢包已被凍結。不過,要徹底追討北韓這些資金,可能要花上數月甚至數年。正因如此,美國當局現正與業界和其他國家政府緊密合作,盡量追蹤資金流向。

這亦解釋了美國為何選擇起訴Tornado Cash的開發者——這是一個專門為用戶混合加密貨幣、增加匿名性的服務,原意是保障私隱,但卻深受網絡罪犯歡迎,用來掩飾資金流向。

美國同時亦嘗試主動出擊,但在加密貨幣世界要防範先於罪案發生,難度極高。最近,美國執法人員突擊搜查了16個州近30個「手提電腦農場」,針對北韓IT工人計劃,至今已拘捕一人、凍結29個賬戶及關閉32個網站。微軟亦已暫停約3,000個與北韓工人有關的Outlook及Hotmail(是的,還有人用Hotmail)電郵賬戶。

規模之大,並非全屬犯罪。著名鏈上追蹤者ZachXBT估計,北韓IT工人每月合共賺取至少276萬美元,這些工人大多以假文件遙距工作,部分單純做工寄錢回國,亦有可能被安插以探查公司漏洞。

美國要徹底遏止這種現象,除了提升大眾警覺,似乎別無他法。遺憾地,或許要等到更多駭客事件和慘痛教訓發生,才會引起真正重視。

更多中國芯片公司籌備上市

中國科技企業上市潮持續升溫。除了香港交易所因科技股上市而受關注,內地交易所亦動作頻頻。兩家GPU(圖像處理器)新貴——摩爾線程和沐曦——即將登陸上海科創板,分別計劃融資11億美元及5億美元。

有趣的是,兩家公司都將美國制裁列為產品開發的重大風險,但同時認為這也是中國本土市場的大機遇。雖然兩者沒有直接關聯,但去年都因研發投入而虧損約2億美元。對於摩爾線程、沐曦,以及上周提及的Reconova(AI視覺)、壁仞科技及澜起科技(兩家AI芯片公司)等企業來說,公開市場融資將是它們挑戰Nvidia等國際巨頭的關鍵。

中國對Nvidia替代品有明顯需求,但這些新創企業亦有意進軍海外。中國頂尖科技企業過去在電訊設備、智能手機、雲計算、電商及消費級AI領域,已成功拓展國際市場。

另一方面,蘋果主要供應商立訊精密據報正籌備今年在香港上市,集資額或超過10億美元。

不過,市場並非一片光明。科技巨頭騰訊和小米在香港股價於六月大幅回落,結束了早前的強勁升勢。

TikTok美國前途依然撲朔迷離

TikTok在美國的命運繼續懸而未決。雖然我們一般只在有新進展時報道,但上周確實有點「動作」。前總統特朗普聲稱,一班「非常有錢的人」準備收購TikTok美國業務,且中國國家主席習近平會批准。

這班人其實就是早前由甲骨文(Oracle)牽頭的財團,成員包括Andreessen Horowitz和黑石集團(Blackstone),但因地緣政治緊張而擱置收購。

實際情況如何?基本上還是沒甚麼新進展。對於中國或非美國科技企業來說,這種反覆拉鋸,可能就是在美國做生意的代價。

同時,TikTok因應特朗普關稅新政,繼續裁減美國電商部門人手,據彭博報道,這已是自四月以來的第三輪裁員。

數據:特朗普關稅新政重創Temu及Shein

我們早知美國新關稅措施重創中國電商平台,但現在有了量化數據。應用分析公司Sensor Tower的數據顯示,三月至六月間:

– Temu每月活躍用戶暴跌51%,降至4,020萬
– Shein跌幅則為12%,降至4,140萬

這並非完全因美國關稅新政所致,後者移除了800美元以下貨品免稅的漏洞。Temu、Shein、TikTok Shop等同時大幅削減廣告預算,這亦令用戶參與度下降。事實上,Temu在2023及2024年曾是美國下載量最高的應用程式,廣告推廣功不可沒。

Shein則希望藉與印度零售巨頭Reliance合作,重返被禁多年的印度市場。不過,Reliance本身去年EBITDA增長僅9%,更需要這次合作帶來新動力。

記者評論:亞洲科技博弈新格局——黑客、芯片、平台與國際規則的多重角力

這一輯亞洲科技新聞,表面上看是黑客、芯片上市、平台裁員與用戶下跌等個別事件,但背後其實勾勒出亞洲科技產業與國際規則、地緣政治、數碼主權和經濟模式的多重角力。

北韓黑客案最耐人尋味之處,是它不只是一宗網絡罪案,而是國家級「網絡戰」的現代版本。美國雖然在追討被盜資產上有些微成績,但面對去中心化、匿名化、全球流動的加密貨幣,傳統執法邏輯明顯力有不逮。這場攻防戰,實質上考驗的是國家之間在數碼主權、金融監管、跨境協作等全新領域的實力。當黑客不再只是個人或犯罪集團,而是國家行為體,這已經是現代戰爭的延伸——甚至可能是未來地緣政治衝突的主戰場。

而中國芯片企業上市潮,則反映出中國科技產業在「卡脖子」壓力下的自強決心。美國制裁一方面是壓力,另一方面卻變成推動本土芯片產業爆發的催化劑。這些企業的國際化野心,亦意味著未來全球芯片生態將更碎片化,技術標準、供應鏈分布、資金流向都會變得更複雜。而且,這種「科技民族主義」不單只發生在中國,印度、東南亞、甚至澳洲等地都有類似現象。

至於TikTok、Temu、Shein等平台的美國命運,則揭示了科技全球化的「逆流」——國家安全、數據主權、經濟保護主義等考量,已經成為國際市場進入門檻。平台企業不再只是簡單的商業競爭者,而是國家政策、民意、甚至國際談判的籌碼。這種局面下,企業需要的不只是創新和執行力,更要有地緣政治的敏感度和策略。

最後,這些新聞亦提醒香港——作為亞洲金融科技樞紐——必須及早思考:我們如何在全球科技規則重塑、數碼主權鬥爭、產業鏈重組中找到自己的定位?如何保護本地創新,並在國際博弈中保持靈活?這些問題,值得每一位關心香港未來的市民、企業與政策制定者深思。

Generate an ultra-realistic, highly ultra-detailed, 8k resolution with 1080x1080 pixel portrait of me using the uploaded image for reference (preserved the likeness and the original face for reference) of a striking, high-resolution portrait of a young woman with long, flowing wavy brunette hair, seated gracefully on a simple black wooden chair in a dimly lit studio. She wears an oversized, off-white knitted sweater that drapes loosely over her frame, slipping off one shoulder to reveal smooth skin and add a subtle touch of sensuality. Her pose is elegant and contemplative: one arm rests gently on the chair’s backrest while her hand delicately supports her chin, and her gaze is directed thoughtfully toward the side, creating an intimate and introspective mood. The lighting is expertly crafted with a single soft, directional light source positioned to the side, casting gentle shadows that sculpt her form and highlight the texture of the knitwear and the natural contours of her legs and arms. This chiaroscuro effect enhances the depth and dimensionality of the image, emphasizing the softness of her skin and the intricate weave of the sweater. The background is a smooth, muted dark gray, providing a minimalist and distraction-free backdrop that contrasts beautifully with her light-colored apparel and warm skin tones. *** The composition is a full-body vertical frame that captures the model’s seated posture with perfect balance, positioning her slightly off-center to create visual interest and harmony. The overall color palette is subdued and warm, featuring neutral tones that evoke a sense of calm and understated elegance. The image is impeccably sharp, showcasing fine details such as the delicate waves of her hair, the subtle folds in the fabric, and the natural texture of her skin. The style is classic and timeless, blending modern minimalism with emotive portraiture to convey quiet strength, beauty, and introspection.
