New UEFI Secure Boot flaw exposes systems to bootkits, patch now
A new UEFI Secure Boot bypass vulnerability tracked as CVE-2024-7344 that affects a Microsoft-signed application could be exploited to deploy bootkits even if Secure Boot protection is active. The vulnerable UEFI application is present in multiple real-time system recovery tools from several third-party software developers. Bootkits represent a critical security threat that is difficult to detect because […]
BIOS flaws expose iSeq DNA sequencers to bootkit attacks
BIOS/UEFI vulnerabilities in the iSeq 100 DNA sequencer from U.S. biotechnology company Illumina could let attackers disable devices used for detecting illnesses and developing vaccines. The Illumina iSeq 100 is advertised as a DNA sequencing system that medical and research labs can use to deliver “rapid and cost-effective genetic analysis.” Firmware security company Eclypsium analyzed […]
BootKitty UEFI malware exploits LogoFAIL to infect Linux systems
Update added below about this bootkit being created by students in Korea’s Best of the Best (BoB) cybersecurity training program. The recently uncovered ‘Bootkitty’ Linux UEFI bootkit exploits the LogoFAIL flaw, tracked as CVE-2023-40238, to target computers running on vulnerable firmware. This is confirmed by firmware security firm Binarly, which discovered LogoFAIL in November 2023 […]
PKfail Secure Boot bypass remains a significant risk two months later
Roughly nine percent of tested firmware images use non-production cryptographic keys that are publicly known or leaked in data breaches, leaving many Secure Boot devices vulnerable to UEFI bootkit malware attacks. Known as ‘PKfail,’ and now tracked as CVE-2024-8105, the supply chain attack is caused by test Secure Boot master key (Platform Key “PK”), which computer […]
PKfail Secure Boot bypass lets attackers install UEFI malware
Hundreds of UEFI products from 10 vendors are susceptible to compromise due to a critical firmware supply-chain issue known as PKfail, which allows attackers to bypass Secure Boot and install malware. As the Binarly Research Team found, affected devices use a test Secure Boot “master key”—also known as Platform Key (PK)—generated by American Megatrends International […]
