Berlin-based researcher Patrick Stewin says he has figured out a way to detect this tricky malware without taxing the CPU. Security software isn’t necessarily looking for malware lurking within peripherals. Instead, it takes advantage of the processing power already present in peripherals like graphics cards. Once infected, DMA attacks can do all sorts of damage, such as copying encryption keys or installing other types of malware for identity theft. Stewin’s work will be presented at the International Symposium on Research in Attacks in October.”]
