New TONTOU CPU attack bypasses Spectre v2 fixes, leaks Linux password hashes

Successfully exploiting the issue requires overcoming several obstacles, including redirecting kernel control flow, precisely aligning interrupts with the post-neutralization window, and using the interrupt handler to poison the branch predictor entry associated with the target indirect branch. The researchers address these challenges through installing ‘timers’ to trigger hardware interrupts, frequent injection of interrupts, and via […]

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 […]
