also all[improper synthesis?] Most uranium that occurs in nature is the isotope U-238; however, the fissile material used in a nuclear power plant or weapon needs to be made from the slightly lighter U-235. Fereydoon Abbasi, a high-ranking official at the Ministry of Defense was seriously wounded. Stuxnet was designed to destroy the centrifuges Iran was using to enrich uranium as part of its nuclear program. While neither government has ever officially acknowledged developing Stuxnet, a 2011 video created to celebrate the retirement of Israeli Defense Forces head Gabi Ashkenazi listed Stuxnet as one of the successes under his watch. With more than 30,000 IP addresses affected in Iran, an official said that the infection was fast spreading in Iran and the problem had been compounded by the ability of Stuxnet to mutate. Stuxnet To get to the bottom of Israel's cyberwarfare on Iran, we spoke to a computer science engineer who frequents open source intelligence groups. [161], The United Kingdom has denied involvement in the worm's creation. In addition, in 2010, a malicious code called Stuxnet damaged the Natanz nuclear power facility in Iran . In the same report, Sean McGurk, a former cybersecurity official at the Department of Homeland Security noted that the Stuxnet source code could now be downloaded online and modified to be directed at new target systems. According to the computer scientist, he received a message a few years ago from a friend who worked at a Russian nuclear power plant in which the source claimed "their internet network [was] badly infected by Stuxnet. The Bush and Obama administrations believed that if Iran were on the verge of developing atomic weapons, Israel would launch airstrikes against Iranian nuclear facilities in a move that could have set off a regional war. This is a much higher frequency than motors operate in most industrial applications, with the notable exception of gas centrifuges. It was designed to specifically to sabotage centrifuges in the Iranian nuclear facility of Natanz. Stuxnet is the first worm of its type capable of attacking critical infrastructure like power stations and electricity grids: those in the know have been expecting it for years. recommend starting with a risk analysis and a control system security assessment. 2012 . The on-site security expert, unable to figure out the cause, contacted a friend of his, a Belarusian named Sergey Ulasen who was working for the antivirus vendor VirusBlokAda. [77] Stuxnet installs malware into memory block DB890 of the PLC that monitors the Profibus messaging bus of the system. LEU quantities could have certainly been greater, and Stuxnet could be an important part of the reason why they did not increase significantly. The first outsiders to notice the effects of the worm were inspectors from the International Atomic Energy Agency (IAEA), who were permitted access to the Natanz facility. Joint effort and other states and targets, Targeting military command, control, communications and intelligence. [114] And, in late 2010 Borg stated, "Israel certainly has the ability to create Stuxnet and there is little downside to such an attack because it would be virtually impossible to prove who did it. It was a marksman's job. Iran had set up its own systems to clean up infections and had advised against using the Siemens SCADA antivirus since it is suspected that the antivirus contains embedded code which updates Stuxnet instead of removing it. Unlike Stuxnet, to which it seems to be related, it was designed to gather information rather than to interfere with industrial operations. The standards and best practices[who?] "[41] Its current name is derived from a combination of some keywords in the software (".stub" and "mrxnet.sys"). U.S. Air Force designates six cybertools as weapons Stuxnet quickly propagated throughout Natanz -- knocking that facility offline and at least temporarily crippling Iran's nuclear program --. By the fall of 2010, the consensus was that Iran's top secret uranium enrichment plant at Natanz was the target and that Stuxnet was a carefully constructed weapon designed to be carried into the . Majid Shahriari, a quantum physicist was killed. However, he explained that a lot about code could be understood from examining the binary in action and reverse-engineering it. [127], Given the growth in Iranian enrichment ability in 2010, the country may have intentionally put out misinformation to cause Stuxnet's creators to believe that the worm was more successful in disabling the Iranian nuclear program than it actually was. [39] The worm contains a component with a build time-stamp from 3 February 2010. [1] Next, the machine infiltrated the Windows-based [142] Also, the number 19790509 appears once in the code and may refer to the date 1979 May 09, the day Habib Elghanian, a Persian Jew, was executed in Tehran. [108], The Institute for Science and International Security (ISIS) report further notes that Iranian authorities have attempted to conceal the breakdown by installing new centrifuges on a large scale. Stuxnet was designed and sent into the area around Iran's Natanz nuclear power plant -- just how may never be known -- to infect a number of computers on the assumption that someone working in the . [22][158] In 2019, it was reported that an Iranian mole working for the Dutch intelligence at the behest of Israel and the CIA inserted the Stuxnet virus with a USB flash drive or convinced another person working at the Natanz facility to do so. In 2020, researcher Facundo Muoz found evidence suggesting that Equation Group collaborated with Stuxnet developers in 2009 by lending them at least one zero-day exploit,[57] and one exploit from 2008[58] that was being actively used in-the-wild by the Conficker computer worm and Chinese hackers. In that piece, Kim Zetter claimed that Stuxnet's "costbenefit ratio is still in question. The exfiltrated data may be used to enable a future Stuxnet-like attack. ], Perry and Collina also noted that a nuclear war by accident is much more likely than Russia launching a first strike on the United States. The Stuxnet computer virus, discovered in 2010 and widely believed to be a joint U.S.-Israeli creation, once disrupted and destroyed Iranian centrifuges at Natanz during an earlier period of .

[3][4][5] The program, started during the Bush administration, was rapidly expanded within the first months of Barack Obama's presidency. [135] American presidential advisor Gary Samore also smiled when Stuxnet was mentioned,[62] although American officials have suggested that the virus originated abroad. This computer worm is designed to transfer data about production lines from our industrial plants to locations outside Iran. The West fears Iran's ultimate goal is to. [68][143][144] Another date that appears in the code is "24 September 2007", the day that Iran's president Mahmoud Ahmadinejad spoke at Columbia University and made comments questioning the validity of the Holocaust. "We could see in the code that it was looking for eight or ten arrays of 168 frequency converters each," says O'Murchu. Two websites in Denmark and Malaysia were configured as command and control servers for the malware, allowing it to be updated, and for industrial espionage to be conducted by uploading information. [91][39] The Guardian, the BBC and The New York Times all claimed that (unnamed) experts studying Stuxnet believe the complexity of the code indicates that only a nation-state would have the abilities to produce it. But if the goal was to destroy a more limited number of centrifuges and set back Irans progress in operating the FEP, while making detection difficult, it may have succeeded, at least temporarily. [21] On 15 July 2010, the day the worm's existence became widely known, a distributed denial-of-service attack was made on the servers for two leading mailing lists on industrial-systems security. "[182] While that may be the case, the media coverage has also increased awareness of cyber security threats. Visiting cyber-sleuths around the globe, Michael Joseph Gross investigates the impact of the Stuxnet worm's . Is the power plant the target of the malware Stuxnet? Many in the U.S. believed the spread was the result of code modifications made by the Israelis; then-Vice President Biden was said to be particularly upset about this. Stuxnet is without a doubt the granddaddy of nation-state viruses. [132][133][134] When questioned whether Israel was behind the virus in the fall of 2010, some Israeli officials[who?] Modern nuclear power plants (NPPs) use a variety of digital technologies, with new technologies such as wireless sensor networks also under active consideration. In fact, while Stuxnet grabbed a lot of headlines due to its dramatic capabilities and cloak-and-dagger origins, it was never much of a threat to anybody other than the Natanz facility that was its original target. Once in control of the PLCs, Stuxnet varied the rotation speeds of the centrifuges while they were in operation in a way that damaged them and left them inoperable in short order. Stuxnet exploited multiple previously unknown Windows zero days. Experts believe that Israel also somehow acquired P-1s and tested Stuxnet on the centrifuges, installed at the Dimona facility that is part of its own nuclear program. [46][66] The driver signing helped it install kernel mode rootkit drivers successfully without users being notified, and thus it remained undetected for a relatively long period of time. A centrifuge is used to spin uranium fast enough to separate the different isotopes by weight via to centrifugal force. It only attacks those PLC systems with variable-frequency drives from two specific vendors: Vacon based in Finland and Fararo Paya based in Iran. It's also possible that it escaped thanks to poor security practices on the part of the Iranians at Natanzit could've been something as simple as someone taking a work laptop home and connecting it to the internet. On 1 September 2011, a new worm was found, thought to be related to Stuxnet. And it was a thorough analysis of the code that eventually revealed the purpose of the malware. It targets the computer systems used to. Prevention of control system security incidents,[82] such as from viral infections like Stuxnet, is a topic that is being addressed in both the public and the private sector. As we noted above, there are other malware families that seem to have functionality derived from Stuxnet; these may be from the same intelligence agency shop, or they might represent freelance hackers who have managed to reverse-engineer some of Stuxnet's power. While this is happening, the PLCs tell the controller computer (incorrectly) that everything is working fine, making it difficult to detect or diagnose what's going wrong until it's too late. The. Stuxnet is a malicious computer worm first uncovered in 2010 and thought to have been in development since at least 2005. The Stuxnet worm is detected. [39], Israel, through Unit 8200,[128][129] has been speculated to be the country behind Stuxnet in many media reports[91][105][130] and by experts such as Richard A. Falkenrath, former Senior Director for Policy and Plans within the US Office of Homeland Security. Absolute Cyber Power. They cited several sources to support this claim including a GAO study that found that many advanced weapon systems in the U.S. use commercial and free software without changing the default passwords. [6], Stuxnet specifically targets programmable logic controllers (PLCs), which allow the automation of electromechanical processes such as those used to control machinery and industrial processes including gas centrifuges for separating nuclear material. Stuxnet, which targeted nuclear power plants in Iran, is still the most widely publicized threat against such systems. The stresses from the excessive, then slower, speeds caused the aluminium centrifugal tubes to expand, often forcing parts of the centrifuges into sufficient contact with each other to destroy the machine. [16][21][63] The Windows component of the malware is promiscuous in that it spreads relatively quickly and indiscriminately.[46]. The sheer number of vulnerabilities exploited is unusual, as typically zero-days are quickly patched in the wake of an attack and so a hacker won't want to reveal so many in a single attack. Last summer, a mysterious computer virus appeared to hit Iran's nuclear program. [39] Developing its many abilities would have required a team of highly capable programmers, in-depth knowledge of industrial processes, and an interest in attacking industrial infrastructure. November 18, 2014. Since 2010, there has been extensive international media coverage on Stuxnet and its aftermath. [66] Symantec estimates that the group developing Stuxnet would have consisted of between five and thirty people, and would have taken six months to prepare. [24] Amongst these exploits were remote code execution on a computer with Printer Sharing enabled,[69] and the LNK/PIF vulnerability,[70] in which file execution is accomplished when an icon is viewed in Windows Explorer, negating the need for user interaction. In an interview, filmmaker Alex Gibney talks about Israel's responsibility for the revelation of the operation and its eventual spread around the world. Stuxnet was developed by the American and Israeli governments and used to wreak havoc on an Iranian nuclear facility called Natanz. [136], In 2009, a year before Stuxnet was discovered, Scott Borg of the United States Cyber-Consequences Unit (US-CCU)[137] suggested that Israel may prefer to mount a cyber-attack rather than a military strike on Iran's nuclear facilities. [29][62] Israel has not publicly commented on the Stuxnet attack but in 2010 confirmed that cyberwarfare was now among the pillars of its defense doctrine, with a military intelligence unit set up to pursue both defensive and offensive options. James Ball. Additionally, the code of Stuxnet is available on the internet, making it an open source cyber weapon potentially capable of attacking power grids, nuclear plants, or other infrastructure if the source code is accurately altered. [175] If the United States, Russia or China (or maybe even the United Kingdom or France) experienced such a cybersecurity attack, the resulting nuclear war would likely produce a nuclear winter, during which 98 percent of humanity would die of starvation if they did not succumb to something else sooner.[176][relevant? Contributing writer, broke into "wide smiles", fueling speculation that the government of Israel was involved with its genesis. [165], In 2018, Gholamreza Jalali, Iran's chief of the National Passive Defence Organisation (NPDO), claimed that his country fended off a Stuxnet-like attack targeting the country's telecom infrastructure. It is not clear whether this attack attempt was successful, but it being followed by a different, simpler and more conventional attack is indicative. [33], On 1 June 2012, an article in The New York Times said that Stuxnet is part of a US and Israeli intelligence operation named Operation Olympic Games, devised by the NSA under President George W. Bush and executed under President Barack Obama.[34]. [151], The fact that John Bumgarner, a former intelligence officer and member of the United States Cyber-Consequences Unit (US-CCU), published an article prior to Stuxnet being discovered or deciphered, that outlined a strategic cyber strike on centrifuges[152] and suggests that cyber attacks are permissible against nation states which are operating uranium enrichment programs that violate international treaties gives some credibility to these claims. Twenty-seven days later, the worm went back into action, slowing the infected centrifuges down to a few hundred hertz for a full 50 minutes. Specifically, it targets centrifuges used to produce the enriched uranium that powers nuclear weapons and reactors. Speaking of the Stuxnet creators, he said, "They opened the box. Its purpose was not just to infect PCs but to cause real-world physical effects. The vulnerability of critical infrastructure has been the subject of some study over recent years, but since the revelation of the digital worm Stuxnet and the impact it is understood to have had on the functioning of the equipment in Iran's nuclear programme, many experts have been concerned that similar attempts to interfere with the physical [65] The worm then uses other exploits and techniques such as peer-to-peer remote procedure call (RPC) to infect and update other computers inside private networks that are not directly connected to the Internet. The FAS report was reviewed by an official with the IAEA who affirmed the study. However, rumor has it that American and Israeli Intelligence wanted to use it to sabotage the Iranian nuclear program. But beyond specific technologies, Stuxnet is significant because it represented the first widely recognized intrusion of computer code into the world of international conflict, an idea that previously had been in the realm of cyberpunk sci-fi. [66][67][68] The number of zero-day exploits used is unusual, as they are highly valued and malware creators do not typically make use of (and thus simultaneously make visible) four different zero-day exploits in the same worm. New and important evidence found in the sophisticated "Stuxnet" malware targeting industrial control systems provides strong hints that the code was designed to sabotage nuclear plants, and .
