【研究揭示#热门应用滥用iPhone推送通知#】 安全研究人员 Tommy Mysk 近日揭露，部分热门 iPhone 应用正在利用推送通知功能秘密发送用户数据，绕过 iOS 系统对后台程序的限制，引发了用户隐私安全担忧。
Mysk 在一段视频中演示了这一做法，他指出，苹果在 iOS 10 中引入的一项推送通知自定义功能被部分开发者“别有用心”地利用了，该功能原本是为了让应用丰富通知内容或解密加密信息，但一些开发商却将其用于更隐蔽的数据传输。Mysk 发现，包括 TikTok、Facebook、Twitter、领英和必应等在内的多个热门应用，正在利用推送通知的短暂后台执行时间，发送用户分析信息。
