国家安全部近日披露了一种新型诈骗手段的运作机制：不法分子在接通电话后刻意保持沉默，促使受害者主动出声回应，借此采集短短数秒的语音样本1。这些极短的音频片段随后被用于AI声纹克隆技术，实现身份冒充和欺诈目的1。
国家安全部警示，AI技术正在将生物特征转化为可被采集和复制的数据，构成多重威胁1。仅需一张照片配合数秒语音，不法分子就能克隆出以假乱真的"数字分身"1。该部门指出，AI可从网络公开素材中批量提取生物特征，而某些应用程序存在过度采集面部与声纹数据的问题，加剧了这一风险1。国家安全部呼吁社会各界提高防范意识，并强调非法获取、出售或提供公民个人信息如人脸照片、视频等，情节严重时将构成侵犯公民个人信息罪1。
China's Ministry of State Security has disclosed a sophisticated fraud scheme in which criminals maintain silence after connecting calls to prompt victims to speak, thereby collecting brief voice samples for artificial intelligence-based voice cloning attacks.1 The agency revealed that just a few seconds of audio can be weaponized to impersonate individuals and perpetrate fraud.1
The ministry warned that AI technology is transforming biological characteristics into reproducible data, creating unprecedented security risks.1 Criminals can extract biometric features in bulk from publicly available online content, while certain applications engage in excessive collection of facial and voice data.1 According to the security agency, a single photograph combined with several seconds of voice recording is sufficient to create a convincing digital replica.1
The State Security Ministry identified multiple threats posed by the misuse of AI, including unauthorized data harvesting, deepfake creation, and illicit information aggregation.1 The agency emphasized the importance of heightened awareness and vigilance against these emerging threats.1 Under Chinese law, individuals who illegally obtain, sell, or provide citizens' personal information such as facial photographs and videos face criminal liability for violating privacy rights when circumstances are deemed serious.1
