安全公司 ESET 的研究人员报告了第一个杀不死的 Linux UEFI Bootkit。该恶意程序被攻击者命名为 Bootkitty,相比 Windows 平台上的类似恶意程序,Bootkitty 相对简陋,关键底层功能不完善,主要感染 Ubuntu,感染其它 Linux 发行版的手段缺乏。安全研究人员猜测它可能是一个概念验证版本,尚未观察到实际感染证据。Bootkit 是一种感染固件的恶意程序,此类恶意程序无法通过格式化硬盘等常规方法杀死。最新发现意味着 UEFI Bootkit 不再只针对 Windows 操作系统。

Telegram does offer end-to-end encrypted communications through Secret Chats, but this is not the default setting. Standard conversations use the MTProto method, enabling server-client encryption but with them stored on the server for ease-of-access. This makes using Telegram across multiple devices simple, but also means that the regular Telegram chats you’re having with folks are not as secure as you may believe. "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. The Russian invasion of Ukraine has been a driving force in markets for the past few weeks. The original Telegram channel has expanded into a web of accounts for different locations, including specific pages made for individual Russian cities. There's also an English-language website, which states it is owned by the people who run the Telegram channels. Individual messages can be fully encrypted. But the user has to turn on that function. It's not automatic, as it is on Signal and WhatsApp.
