东北大学隐私与安全研究团队与《消费者报告》合作，开展了联网汽车生态系统的首个大规模隐私测量研究1。该研究测试了21款新型车辆及其30个配套移动应用，时间跨度从2024年10月至2025年8月1。研究已获同行评审，将在IMC '26发表1。
研究发现，联网汽车及其应用持续向制造商和第三方服务器发送消费者私人数据，且消费者对数据一旦离开设备后的流向无法进行有效控制1。这一发现尤其值得关注，因为全球销售的车辆中，超过75%已内置联网功能1。研究人员在法拉第笼中测试了11辆电动车的蜂窝网络阻断效果1。据《消费者报告》提供的测试车队造价计算，独立组建同等规模的车队成本将超过120万美元1。
Researchers from Northeastern University's privacy and security team partnered with Consumer Reports to conduct the first large-scale privacy measurement study of the connected car ecosystem.1 The investigation tested 21 recent vehicle models and 30 accompanying mobile applications, revealing that connected cars and their associated apps continuously transmit private consumer data to manufacturers and third-party servers, while consumers lack control over how their information is used once it leaves their devices.1
The study, which has undergone peer review and will be published at IMC '26, examined data flows across the automotive industry at a scale that would have required independent assembly of a test fleet costing over $1.2 million.1 The research spanned from October 2024 through August 2025 and included testing of 11 electric vehicles within a Faraday cage—an environment providing approximately 93 decibels of cellular signal attenuation—to assess network blocking effectiveness.1 These findings arrive at a time when over 75 percent of vehicles sold globally now include connected features, underscoring the widespread nature of the privacy challenges identified in the research.1
