Although it hasn't been seen in the wild yet A new ransomware strain dubbed HybridPetya was able to exploit a patched vulnerability to bypass Unified Extensible Firmware Interface (UEFI) Secure Boot on unrevoked Windows systems, making it the fourth publicly known bootkit capable of punching through the feature and hijacking a PC before the operating system loads.…

Cybersecurity researchers have discovered a new ransomware strain dubbed HybridPetya that resembles the notorious Petya/NotPetya malware, while also incorporating the ability to bypass the Secure Boot mechanism in Unified Extensible Firmware Interface (UEFI) systems using a now-patched vulnerability disclosed earlier this year

The now-patched vulnerabilities exist at the firmware level and enable deep persistence on compromised systems.

Cybersecurity researchers have disclosed now-patched critical security flaws in the firmware of Dahua smart cameras that, if left unaddressed, could allow attackers to hijack control of susceptible devices

UEFI Vulnerability Threatens Systems with Silent CompromiseHackers could circumvent the protections of Secure Boot by silently disabling it through an attack that potentially affects a wide swath of Windows laptops and servers. Microsoft issued a patch this month and hackers would already need admin access and physical access to a target machine.

Persistent Attack Grants Remote SSH Access via ExploitSomeone - possibly nation-state hackers - appears to be constructing a botnet from thousands of Asus routers in hacking that survives a firmware patch and reboots. Nearly 9,000 routers have been compromised and the number is growing, say researchers.

​AMD has released mitigation and firmware updates to address a high-severity vulnerability that can be exploited to load malicious CPU microcode on unpatched devices. [...]
