Windows' original Secure Boot certificates expire in June—here's what you (may) need to do

Microsoft has warned that the original Secure Boot certificates used by Windows PCs will expire in June and October of this year. These certificates are crucial for verifying bootloaders to ensure that unverified software can’t be loaded at startup. PCs that do not update to the new certificates before the expiration date may face issues booting new operating systems and installing security patches. Microsoft and major PC manufacturers have been preparing for this transition, and most systems should update seamlessly through Windows Update. Users can check if their PCs have the new certificates using a PowerShell command. Microsoft encourages users who need help with the update to use its customer support services.

State actor targets 155 countries in “Shadow Campaigns”espionage op

A state-aligned cyberespionage threat group, tracked as TGR-STA-1030/UNC6619, has conducted a global-scale operation dubbed the 'Shadow Campaigns,' targeting government infrastructure in 155 countries. The group has been active since at least January 2024 and is believed to operate from Asia. The attacks focus on government ministries, law enforcement, border control, finance, trade, energy, mining, immigration, and diplomatic agencies. Unit 42 researchers confirmed compromises of at least 70 organizations across 37 countries, including entities in the Americas, Europe, Australia, and Taiwan. The threat group uses highly tailored phishing emails and exploits known vulnerabilities to gain initial access, employing a custom Linux kernel eBPF rootkit called 'ShadowGuard' to evade detection.
