The worm was covertly damaging Iran's nuclear weapons ambitions for at least a year before it was discovered in 2010. Pictorial Description Of How The Stuxnet Attack Worked In 2009, an earlier version of Stuxnet was manipulating the valves to increase the pressure inside centrifuges, damaging both the valve and the centrifuge, derailing the uranium enrichment process.Д«elow is an excellent depiction of how the Stuxnet virus attack was executed. Whilst the speed was being manipulated by the Stuxnet worm, it was relaying false data to the SCADA's and PLC's and therefore the Siemens Step 7 application, giving the impression that there was no issue to the instrument mechanics working at the facility.

Phase 3 of the code then execute the payload, which manipulated the controls that managed the speed and duration at which the centrifuges spun at, causing them to burn out. The Siemens's Step 7 application was used to control the SCADA and PLC's, which in turn controlled the centrifuges.

Phase 2 of the code then identified the specific Siemens's Step 7 Software running on the facilities Microsoft-based computers. Once the USB Pen's were plugged in to the nuclear facilities Windows-based computers, the Stuxnet worm replicated itself to all other available Microsoft Windows-based computers on the nuclear facilities networks. The engineers at these companies were cleared to work on the SCADA and PLC's, and anti-virus systems at the time could not have detected the malicious code. This was achieved by the intelligence agencies infiltrating five of the nuclear facilities suppliers and covertly adding the Stuxnet code to their systems.ДЄlthough the companies have never been formally identified, they are believed to include Fooland Technic, Bahpajooh, Neda and Control Gostar Jahed. Therefore, the worm's infiltration mechanism was by USB Pen. The nuclear facilities network was not connected to the wider Internet (known as air-gapped). Phase 1 targeted the computers used to manage the SCADA and PLC devices that controlled the centrifuges. The process of infection was remarkable, yet simple in its execution across three main phases. The privilege escalation exploits enabled the worm to covertly execute its code and cause the centrifuge damage.

The shared print spooler vulnerability was used to spread the worm on networks using shared printing facilities a common sharing mechanism at the time. The LNK file extension was used to enable the worm to spread using USB pens.

Two vulnerabilities related to privilege escalation.

The LNK file extension for creating shortcuts.

The four exploited vulnerabilities were:.

The Stuxnet worm was carefully crafted to exploit 4x Microsoft Windows operating system zero-day vulnerabilities that were known to the intelligence agencies, but were not publicly disclosed. It is estimated by Kaspersky security experts, some of whom were involved in the reverse engineering of the Stuxnet programming code, that it would have taken a team up to ten coders, two to three years to create this sophisticated worm.

I was following these discussions that the go ahead for Operation Olympic Games was given. government in the White House Situation Room. However, according to Kaspersky's Roel Schouwenberg, it is rumoured that the results of a prototype Stuxnet which destroyed a test centrifuge was shown to the U.S. Operation Olympic Games was therefore seen as a non-violent alternative to curtailing Iran's nuclear programme.ДЄt the time, there was uncertainly about whether such as cyber attack on hardware was even possible. President Mahmoud Ahmadinejad's Visit To The Natanz Nuclear Facility The Stuxnet program was likely triggered by the comments made by Iran's President Mahmoud Ahmadinejad about Israel being a 'disgraceful bot' that should be 'wiped off the face of the earth'. The Americans and Israelis were concerned about Iran's drive to develop their own nuclear weapons, and the consequences this would have on the stability of the middle-east, and the safety of Israel. Bush, and continued under the Presidency of Barack Obama. This program is suspected of starting in 2005, under President George W. and Israeli Intelligence agencies collaborated on developing the worm in a classified program, code named Operation Olympic Games National Security Agency (NSA), the Central Intelligence Agency (CIA), and the Israeli Intelligence Agency. The notoriety of this worm was confirm when it appears to have been created by nation-state intelligence agencies.ДЄlthough no one has claimed formal responsibility, it is highly suspected the culprits were the U.S. Satellite Image Of The Natanz Nuclear Facility In Iran
