Which of the following were payload features of Stuxnet?

• Reprogrammed PLCs to change centrifuge rotation rates

• Deliver false information to control stations

• Change the temperature of centrifuges

• Demand bitcoin ransom to unlock files

• Encrypt hard drives of infected devices

Stuxnet was designed to attack

• Russian-built missile systems

• Iranian nuclear reactors

• An Iranian uranium enrichment facility

• An Israeli air defense operation

Operation ORCHARD was:

• The code name for the Stuxnet program

• An Israeli military operation against a Syrian nuclear facility

• A Russian air defense exercise

• An American plan to infect Apple computers

Stuxnet was unique because:

• It operated independently

• It fit on a flash drive

• It could jump an air gap

• It took 6 months to reverse engineer

As a result of the Stuxnet attack, the Iranians:

• sued the U.S. for millions of dollars

• gave up their plans to build nuclear weapons

• developed their own military cyber capabilities

• formally complained to the U.N. for the sneak attack

• they bribed Netanz employees to infect the computers

• the used social engineering tricks to pass along infected USB drives

• they used dial-up connections

Why are cyberweapons more difficult to monitor by treaty?

• they can be developed virtually anywhere using computers

• you can only track them on the web

• you can only track them using anti-virus software

• they all use zero-day exploits

What is a zero-day exploit?

• a programming flaw that has not been discovered by the producer

• a program loophole that allows access to source code after installation

• a recurring clock malfunction that resets each day

• the average time a new piece of malware is active before it is discovered

How many zero-day exploits were discovered in the Stuxnet code?

• 1

• 2
