I recently bought a second hand Nvidia video card which runs in SLI mode with my default video card. Can it be infected with a malicious program added by the previous owner, steal data from the system (as PCIe has DMA) and send it through ethernet/wireless?

    Maybe, yes. But if you are not a spy/NSA agent/supervillain, very unlikely.

  • Yeah this would be a DMA attack.

  • If there was a malicious code, would it be located in the bios of the video card or can it reside in another place?
