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。

Russians and Ukrainians are both prolific users of Telegram. They rely on the app for channels that act as newsfeeds, group chats (both public and private), and one-to-one communication. Since the Russian invasion of Ukraine, Telegram has remained an important lifeline for both Russians and Ukrainians, as a way of staying aware of the latest news and keeping in touch with loved ones. "There is a significant risk of insider threat or hacking of Telegram systems that could expose all of these chats to the Russian government," said Eva Galperin with the Electronic Frontier Foundation, which has called for Telegram to improve its privacy practices. "Like the bombing of the maternity ward in Mariupol," he said, "Even before it hits the news, you see the videos on the Telegram channels." Continuing its crackdown against entities allegedly involved in a front-running scam using messaging app Telegram, Sebi on Thursday carried out search and seizure operations at the premises of eight entities in multiple locations across the country. Groups are also not fully encrypted, end-to-end. This includes private groups. Private groups cannot be seen by other Telegram users, but Telegram itself can see the groups and all of the communications that you have in them. All of the same risks and warnings about channels can be applied to groups.
