惡意程式入侵手機App!偷你加密貨幣錢包!




發現Android和iOS應用程式開發工具包中的加密貨幣盜竊惡意軟件:卡巴斯基

卡巴斯基實驗室表示,Google和Apple手機應用程式的開發工具包中包含惡意軟件,該軟件可以掃描用戶的圖片以尋找加密貨幣錢包的恢復短語。

根據網絡安全公司卡巴斯基的報告,惡意軟件開發工具包被用於在Google Play商店和Apple應用商店上製作應用程式,並掃描用戶的圖片以尋找加密貨幣錢包的恢復短語,以便盜取其中的資金。

卡巴斯基的分析師謝爾蓋·普扎和德米特里·卡林在2月4日的報告中指出,一旦名為SparkCat的惡意軟件感染設備,它會通過光學字符識別(OCR)技術,使用不同語言的特定關鍵詞搜索圖片。

他們寫道:「入侵者竊取加密貨幣錢包的恢復短語,這足以完全控制受害者的錢包,進一步盜取資金。」

「需要注意的是,這種惡意軟件的靈活性使其不僅能竊取秘密短語,還能從相冊中竊取其他個人數據,例如消息內容或可能保留在截圖中的密碼。」

一位受害者在應用程式頁面上留下了Google評論。

卡巴斯基的分析師建議,不要將敏感信息存儲在截圖或手機的圖片相冊中,而應使用密碼管理器。他們還建議刪除任何可疑或感染的應用程式。

普扎和卡林表示,在Android應用中,這種惡意軟件使用一個名為Spark的Java組件,偽裝成分析模塊,並在GitLab上存儲一個加密配置文件,該文件提供命令和操作更新。

一個基於信任的網絡模塊使用Google ML Kit OCR從感染設備的圖片中提取文本,搜索可以在攻擊者的設備上加載加密貨幣錢包的恢復短語,而無需知道密碼。

卡巴斯基估計,自從該惡意軟件在大約三月開始活躍以來,已經下載了約242,000次,主要針對歐洲和亞洲的Android和iOS用戶。

卡巴斯基表示,該惡意軟件存在於Google和Apple應用商店中的數十個應用中,包括真實和假冒的應用,但它們都具備相同的特徵,例如使用Rust語言,這在移動應用中「很少見」,以及跨平台能力和使分析和檢測變得困難的混淆技術。

普扎和卡林表示,目前尚不清楚受影響的應用程序是「因供應鏈攻擊而感染,還是開發者故意將木馬嵌入其中」。

「一些應用程序,如食品配送服務,看起來是合法的,而其他應用則顯然是為了誘騙受害者而製作的——例如,我們看到幾個類似的『消息應用』,都是同一開發者製作的,並帶有AI功能。」他們補充道。

普扎和卡林表示,該惡意軟件的來源尚不清楚,無法歸因於任何已知團體,但它與ESET研究人員在2023年3月發現的一次活動類似。

然而,這對分析師在代碼中發現了用中文寫的評論和錯誤描述,讓他們「有理由相信,這個惡意模塊的開發者精通中文」。

谷歌和蘋果尚未立即對評論請求作出回應。

這一事件突顯了在數位時代,網絡安全的重要性與日俱增。隨著越來越多的人使用手機進行金融交易,這類針對加密貨幣的攻擊只會變得更加普遍。用戶必須提高警覺,並採取必要措施來保護自己的數據,尤其是在使用不明來源的應用時。這不僅是對個人資產的保護,更是對整個數字金融生態系統的負責。

​"Close-up, dramatic split lighting combined with linear shadows, black background, glossy lips and subtle skin texture, photorealistic digital art, professional portrait photography. 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.
