Linux 安全工程师 Andrey Konovalov 在本月举行的 POC 2024 安全会议上介绍了如何秘密关闭 ThinkPad 摄像头 LED 指示灯的方法。他开发的概念验证程序通过重刷 ThinkPad X230 摄像头的固件去关闭 LED 指示灯,在用户不知情下悄悄摄录像。今天大部分笔记本电脑都提供了摄像头盖子,可以在不使用时盖住摄像头。他的 Lights Out 源代码发布在 GitHub 上。

But Kliuchnikov, the Ukranian now in France, said he will use Signal or WhatsApp for sensitive conversations, but questions around privacy on Telegram do not give him pause when it comes to sharing information about the war.
