Rootkits on a PCI Card?


rootkit2 A well-respected British security researcher has found a way to use a PCI device to plant an offensive rootkit on Windows machines. John Heasman, principal security consultant at NGSS (Next-Generation Security Software) released a research paper on the Daily Dave mailing list discussing a means of persisting a rootkit on a PCI device containing a flashable expansion ROM...

Abstract:

"In February 2006, [I] presented a means of persisting a rootkit in the system BIOS via the Advanced Configuration and Power Interface (ACPI). It was demonstrated that the ACPI tables within the BIOS could be modified to contain malicious ACPI Machine Language (AML) instructions that interacted with system memory and the I/O space, allowing the rootkit bootstrap code to overwrite kernel code and data structures as a means of deployment.
