If I were the CIO, CTO or the IT management type responsible for American banks, financial institutions, energy companies, or major (and not-so-major) corporations, I would call in my network administrators and system administrators and have them write firewall rules blocking everything from Iran. If there is an economic embargo, there should be an internet embargo as well.
As a public service, here is a list of IP addresses to write the firewall wall rules preventing any access at all from Iran.

Come to think of it, I should do this with China too. It is ironic that the minute that I deploy a new server, I start getting clever scripted hack attacks from institutions in China, like the meteorological institute. I think that firewall blocking from unfriendlies, should be the first step in protecting your digital assets.
