Malware Running On Graphics Cards 103

An anonymous reader writes "Given the great potential of general-purpose computing on graphics processors, it is only natural to expect that malware authors will attempt to tap the powerful features of modern GPUs to their benefit. In this paper, the authors demonstrate the feasibility of implementing a malware that can utilize the GPU (PDF) to evade virus scanning applications. Moreover, the authors discuss the potential of more sophisticated attacks, like accessing the screen pixels periodically to harvest private data displayed on the user screen, or to trick the the user by displaying false, benign-looking information when visiting rogue web sites (e.g., overwriting suspicious URLs with benign-looking ones in the browser's address bar)."

Do not underestimate the value of print statements for debugging.
