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. – Tom K. Apr 25 '18 at 13:46
  • Yeah this would be a DMA attack. – bigC5012 Apr 25 '18 at 19:22
  • If there was a malicious code, would it be located in the bios of the video card or can it reside in another place? – fstfn Apr 25 '18 at 20:13
