Stuxnet Wikipedia. Stuxnet is a maliciouscomputer worm, first uncovered in 2. Kaspersky Lab. Thought to have been in development since at least 2. SCADA systems and was responsible for causing substantial damage to Irans nuclear program. Although neither country has admitted responsibility, since 2. AmericanIsraelicyberweapon. Stuxnet specifically targets programmable logic controllers PLCs, which allow the automation of electromechanical processes such as those used to control machinery on factory assembly lines, amusement rides, or centrifuges for separating nuclear material. Exploiting four zero day flaws,3 Stuxnet functions by targeting machines using the Microsoft Windows operating system and networks, then seeking out Siemens Step. Stuxnet reportedly compromised Iranian PLCs, collecting information on industrial systems and causing the fast spinning centrifuges to tear themselves apart. Stuxnets design and architecture are not domain specific and it could be tailored as a platform for attacking modern supervisory control and data acquisition SCADA and PLC systems e. This activity helps students understand that science writing is organized in identifiable patterns called text structures. Understanding and using these different. Tech and Science topics phones, computers, gadgets, and the Internet, astronomy earth science, climate weather, environment green living and much more. Europe, Japan and the US. Stuxnet reportedly ruined almost one fifth of Irans nuclear centrifuges. Targeting industrial control systems, the worm infected over 2. Stuxnet has three modules a worm that executes all routines related to the main payload of the attack a link file that automatically executes the propagated copies of the worm and a rootkit component responsible for hiding all malicious files and processes, preventing detection of the presence of Stuxnet. It is typically introduced to the target environment via an infected USB flash drive. The worm then propagates across the network, scanning for Siemens Step. PLC. In the absence of either criterion, Stuxnet becomes dormant inside the computer. If both the conditions are fulfilled, Stuxnet introduces the infected rootkit onto the PLC and Step. PLC while returning a loop of normal operations system values feedback to the users. In 2. 01. 5, Kaspersky Labs noted that the Equation Group had used two of the same zero day attacks, prior to their use in Stuxnet, and commented that the similar type of usage of both exploits together in different computer worms, at around the same time, indicates that the Equation Group and the Stuxnet developers are either the same or working closely together. DiscoveryeditStuxnet, discovered by Sergey Ulasen, initially spread via Microsoft Windows, and targeted Siemens industrial control systems. While it is not the first time that hackers have targeted industrial systems,1. PLC rootkit. 1. 41. The worm initially spreads indiscriminately, but includes a highly specialized malware payload that is designed to target only Siemens supervisory control and data acquisition SCADA systems that are configured to control and monitor specific industrial processes. Stuxnet infects PLCs by subverting the Step 7 software application that is used to reprogram these devices. Different variants of Stuxnet targeted five Iranian organizations,2. Iran 1. 92. 12. Symantec noted in August 2. Iran. 2. 3 Siemens stated that the worm has not caused any damage to its customers,2. Iran nuclear program, which uses embargoed Siemens equipment procured secretly, has been damaged by Stuxnet. Kaspersky Lab concluded that the sophisticated attack could only have been conducted with nation state support. Iso Burner With Key Programs. This was further supported by the F Secures chief researcher Mikko Hyppnen who commented in a Stuxnet FAQ, Thats what it would look like, yes. In May 2. 01. 1, the PBS program Need To Know cited a statement by Gary Samore, White House Coordinator for Arms Control and Weapons of Mass Destruction, in which he said, were glad they the Iranians are having trouble with their centrifuge machine and that we the US and its allies are doing everything we can to make sure that we complicate matters for them, offering winking acknowledgement of US involvement in Stuxnet. According to The Daily Telegraph, a showreel that was played at a retirement party for the head of the Israel Defense Forces IDF, Gabi Ashkenazi, included references to Stuxnet as one of his operational successes as the IDF chief of staff. On 1 June 2. 01. 2, an article in The New York Times said that Stuxnet is part of a US and Israeli intelligence operation called Operation Olympic Games, started under President George W. Bush and expanded under President Barack Obama. On 2. 4 July 2. 01. Chris Matyszczyk from CNET3. Atomic Energy Organization of Iran e mailed F Secures chief research officer Mikko Hyppnen to report a new instance of malware. On 2. 5 December 2. Iranian semi official news agency announced there was a cyberattack by Stuxnet, this time on the industries in the southern area of the country. The virus targeted a power plant and some other industries in Hormozgan province in recent months. According to expert Eugene Kaspersky, the worm also infected a nuclear powerplant in Russia. Kaspersky noted, however, that since the powerplant is not connected to the public Internet, the system should remain safe. HistoryeditThe worm was at first identified by the security company Virus. Blok. Ada in mid June 2. Journalist Brian Krebss blog posting on 1. July 2. 01. 0 was the first widely read report on the worm. The original name given by Virus. Blok. Ada was Rootkit. Tmphider 3. 7 Symantec however called it W3. Temphid, later changing to W3. Stuxnet. 3. 8 Its current name is derived from a combination of some keywords in the software. The reason for the discovery at this time is attributed to the virus accidentally spreading beyond its intended target the Natanz plant due to a programming error introduced in an update this led to the worm spreading to an engineers computer that had been connected to the centrifuges, and spreading further when the engineer returned home and connected his computer to the internet. Kaspersky Lab experts at first estimated that Stuxnet started spreading around March or April 2. June 2. 00. 9. 1. On 1. 5 July 2. 01. This attack, from an unknown source but likely related to Stuxnet, disabled one of the lists and thereby interrupted an important source of information for power plants and factories. On the other hand, researchers at Symantec have uncovered a version of the Stuxnet computer virus that was used to attack Irans nuclear program in November 2. Iran was still setting up its uranium enrichment facility. The second variant, with substantial improvements, appeared in March 2. Stuxnet was not spreading fast enough a third, with minor improvements, appeared in April 2. The worm contains a component with a build time stamp from 3 February 2. In the United Kingdom on 2. Kostenlos Chat Deutsch. November 2. 01. 0, Sky News reported that it had received information from an anonymous source at an unidentified IT security organization that Stuxnet, or a variation of the worm, had been traded on the black market. Affected countrieseditA study of the spread of Stuxnet by Symantec showed that the main affected countries in the early days of the infection were Iran, Indonesia and India 4. Country.
