What Is Stuxnet Virus And How Does It Work?

What Is Stuxnet Virus?

Stuxnet Virus is a rootkit exploit that targets supervisory control and data acquisition (SCADA) systems. SCADA systems are used widely for industrial control systems, such as power, water and sewage plants, as well as in telecommunications and oil and gas refining.
When Stuxnet Virus was first discovered, its purpose wasn’t fully understood. However, it was clear it had a complex design. Many believe that a team of expert programmers working over a period of several months created it.

How Does It Work?

Stuxnet Virus spreads via the internet and on USB sticks, just like most other viruses. And the way it does this is not particularly clever or well hidden. To reach its target, Stuxnet Virus needs to spread via USB sticks.
USB sticks allow it to penetrate industrial systems disconnected from the Internet and thought to be safe from malware. However, apparent mistakes mean it also spreads via the Internet.
Once Stuxnet infects a computer, the worm copies itself to any flash drives subsequently connected to the computer. It then spreads from those flash drives to other computers.

What Is So Special About Stuxnet Virus?

Like the Zeus banking Trojan, Stuxnet code covered its tracks using stolen digital certificates to trick the operating system into letting Stuxnet Virus install a rootkit. The malware could also avoid detection by traditional intrusion detection systems (IDS).
Many believe that programmers did not design Stuxnet for espionage, but rather to wipe out a large portion of Iran’s nuclear centrifuges.
It was designed to limit the acceleration of its spread by infecting a maximum of three computers from a single flash drive. Additionally, Stuxnet was very good at hiding on systems.

Who Was Stuxnet Aimed At?

Even though the Stuxnet makers included measures to limit its spread, something went wrong.
Stuxnet was aimed at a specific target list – experts designed it to infiltrate heavy-duty industrial control programs that monitor and manage factories, oil pipelines, power plants and other critical installations.
Somehow, it spread to thousands of PCs outside Iran, in countries such as China and Germany, Kazakhstan and Indonesia.
