警惕!AI詐騙假冒警察聲音

Ai




小心「警察」騙局

警方警告,AI騙子利用技術模仿警察聲音,令人感到「恐怖」和「真實」。

AI技術讓騙子更容易冒充警察。最近,鹽湖城警察局警告,一宗電郵騙案使用AI技術成功模仿警察局長Mike Brown的聲音。

一名市民收到一封可疑電郵,內附一段影片,顯示警察局長聲稱他們「欠聯邦政府近十萬美元」。

為了騙取目標,騙子將Brown以往電視訪問的真實片段與AI生成的音訊剪輯在一起。鹽湖城警察局表示,這些音訊「清晰且非常接近Brown局長的聲音,可能令社區成員相信信息的真實性。」

多年來,聯邦調查局一直警告騙子試圖冒充警察或政府官員進行勒索。隨著AI聲音克隆技術的進步,這些騙局可能變得更難識破,甚至像OpenAI這樣的前瞻性公司也因擔心潛在濫用而猶豫不決是否發布最新技術。

鹽湖城警察局指出,技術精通的市民可能在模仿警察局長的電郵中發現一些線索。仔細聆聽會發現「消息有不自然的語音模式,某些單詞有奇怪的重音,語調不一致」,以及「從一句到下一句有可檢測的聲音編輯。」最明顯的是,該騙局電郵來自「一個Google帳戶,電郵中有鹽湖城警察局的名字後加上數字」,而非警察局的官方電郵域名「slc.gov」。

鹽湖城警察局並非唯一面對AI警察冒充者的警局。今年夏天,塔爾薩也遇到類似問題,當時騙子開始打電話給居民,用一個設計得像塔爾薩警官Eric Spradlin的假聲音。據塔爾薩公共電台報導,一名收到電話的軟件開發者Myles David表示,儘管了解AI風險,但他仍「措手不及」,不得不致電警方確認電話不真實。

David說:「那聽起來就像是一次非常隨意的對話,就好像這個人真的期望與我交談一樣。他使用了我的名字和姓氏,談話非常隨意。這就是為什麼聽起來那麼真實,最終也那麼可怕。」

與鹽湖城明顯假的電郵地址不同,一名遭塔爾薩騙局針對的網絡安全教授Tyler Moore告訴塔爾薩公共電台,騙子相對容易讓詐騙電話看似來自塔爾薩警察線路。

警方建議對假警察報警

這種新興的AI濫用不限於美國。今年三月,一名名為Kaveri的用戶在X平台上發帖,警告一名騙子假裝是印度警察,威脅如果她不照做,就會帶走她的小女兒。

該騙子模仿了她女兒的聲音,這是去年被標記為令人擔憂的趨勢之一,壞人通過使用AI冒充陷入困境的親人來騙取成千上萬美元。

對於Kaveri來說,最終在詢問一些具體問題後,她意識到女兒並不在所謂的警察那裡。但據《印度快報》報導,其他被類似騙局針對的人被騙,最終損失金錢。

全球警方希望提高對AI聲音騙局的風險意識,以減少傷害,建議市民核實來自警察的電話,並詢問騙子可能無法回答的具體問題。

編輯評論

這篇文章揭示了AI技術在詐騙中被濫用的危險性。隨著科技的進步,騙子不再需要依賴傳統手法,而是能夠利用先進的AI技術來模仿權威人士的聲音,這對公眾的信任構成了重大威脅。這種技術的濫用不僅僅是騙取金錢,更可能對社會秩序造成嚴重影響。未來,我們需要加強對AI技術的監管,並提高公眾對這類新型騙局的警覺性。此外,技術公司也應該承擔起更多的社會責任,在開發過程中考慮可能的濫用情況,並設計出更有效的防範措施。這是一場技術與道德的博弈,我們必須謹慎應對。

A low-angle, wide-lens street shot in a bustling cityscape (similar to Shibuya, Tokyo). A young woman crouches confidently beside a modified, glossy purple sports car with a Japanese license plate. She wears a black graphic tee, cargo pants, white sneakers, and silver jewelry. The background features tall glass skyscrapers, colorful billboards, neon signage, and warm late-afternoon lighting. Strong perspective distortion emphasizes the height of the buildings and the car’s aggressive stance. The mood is stylish, bold, and modern, capturing urban automotive culture with a cinematic, hyper-real aesthetic. High detail, high contrast, crisp reflections, editorial fashion vibe, dynamic street energy. Create a hyper-realistic 8K close-up body portrait of a male model, using the uploaded photo as the exact facial reference. Maintain 100% accuracy of the facial features — do not alter or modify any aspect of the face. Render the skin texture, lighting, and overall composition with photo-realistic detail, ensuring lifelike color tones and natural depth of field. A man with his original hairstyle, he is standing confidently, hands in his pockets, looking directly at the camera. He is wearing a simple, light beige crew-neck sweater and dark trousers.
He is positioned between two decorated Christmas trees. The tree to his left is adorned with gold and white ornaments and warm lights, with wrapped red and gold gifts visible at its base. The tree to his right is decorated with red and gold ornaments. The background shows a warm, indoor setting, likely a home, with soft lighting, creating a festive and inviting atmosphere. The overall impression is one of relaxed holiday cheer. An ultra realistic portrait of a young man (facial detail 100% matches with the reference photo) relaxing on a wooden balcony with a scenic view of green mountains in the background. Golden-hour sunlight from the left side creates a warm glow, soft highlights on his hair and shoulders, and a subtle sun flare. He is wearing a black t-shirt in a white shirt with long sleeve, a black ripped jeans and black white sport shoes. his short straight hair is blowing by the morning wind. He sits with his body slightly angled, shoulders turned to the right side of the frame, one leg casually folded up onto the chair.

He holds a white cup emitting light steam, suggesting a freshly made hot drink. His face turns gently to the right with a subtle, relaxed smile, giving a calm and peaceful expression. The environment is an outdoor highland area with silhouettes of hills and trees in the distance, softly darkened by the backlit sunlight.

Camera angle is low angle level but slightly from the left side, creating a natural and intimate framing. Background is softly blurred with shallow depth of field, using a wide-aperture lens. Warm, earthy, soft color tones
