Hmmm, I also work at one of these unis and would be very surprised if it is how they day. All research considered potentially a risk to security is hosted and researchers vetted, and no way would explicit Iranian funding be permitted to research so open to being used.
I suspect either it's got in through the back door (ie source of funding being obscured, unlikely), or more likely the research was funded and carried out for a different purpose but has since been appropriated.
