I was recently asked about the security risks that may be posed by using Folding@home. I read about the digital signing and restricted download servers, but I could not find any information on how the program transfers data. Such as what protocol does the program use? I also could not find any information on known vulnerabilities with the software. Does anyone know of any? Offhand I would think of an attacker finding a way to phish users or spoof the download server and then attempt to exploit a buffer overflow using the processes or services that Folding@home uses to transfer data. Any comments community?
