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。

Telegram | DID YOU KNOW?

Date: |

The regulator said it had received information that messages containing stock tips and other investment advice with respect to selected listed companies are being widely circulated through websites and social media platforms such as Telegram, Facebook, WhatsApp and Instagram. On February 27th, Durov posted that Channels were becoming a source of unverified information and that the company lacks the ability to check on their veracity. He urged users to be mistrustful of the things shared on Channels, and initially threatened to block the feature in the countries involved for the length of the war, saying that he didn’t want Telegram to be used to aggravate conflict or incite ethnic hatred. He did, however, walk back this plan when it became clear that they had also become a vital communications tool for Ukrainian officials and citizens to help coordinate their resistance and evacuations. "There are several million Russians who can lift their head up from propaganda and try to look for other sources, and I'd say that most look for it on Telegram," he said. I want a secure messaging app, should I use Telegram? Channels are not fully encrypted, end-to-end. All communications on a Telegram channel can be seen by anyone on the channel and are also visible to Telegram. Telegram may be asked by a government to hand over the communications from a channel. Telegram has a history of standing up to Russian government requests for data, but how comfortable you are relying on that history to predict future behavior is up to you. Because Telegram has this data, it may also be stolen by hackers or leaked by an internal employee.
