Stuxnet is a Malware computer worm first uncovered on June 17, 2010, and thought to have been in development since at least 2005. Stuxnet targets supervisory control and data acquisition (SCADA) systems and is believed to be responsible for causing substantial damage to the Iran nuclear program after it was first installed on a computer at the Natanz Nuclear Facility in 2009. Although neither the United States nor Israel has openly admitted responsibility, multiple independent news organizations claim Stuxnet to be a cyberweapon built jointly by the two countries in a collaborative effort known as Operation Olympic Games. The program, started during the Bush administration, was rapidly expanded within the first months of Barack Obama's presidency.
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 for separating nuclear material. Exploiting four zero-day flaws in the systems, Stuxnet functions by targeting machines using the Microsoft Windows operating system and networks, then seeking out Siemens Step7 software. Stuxnet reportedly compromised Iranian PLCs, collecting information on industrial systems and causing the fast-spinning centrifuges to tear themselves apart. Stuxnet's design and architecture are not domain-specific and it could be tailored as a platform for attacking modern SCADA and PLC systems (e.g., in factory assembly lines or power plants), most of which are in Europe, Japan and the United States. (2011). 9781612849720 ISBN 9781612849720 Stuxnet reportedly destroyed almost one-fifth of Iran's nuclear centrifuges. Targeting industrial control systems, the worm infected over 200,000 computers and caused 1,000 machines to physically degrade.
Stuxnet has three modules: a Computer worm that executes all routines related to the main payload of the attack, a File shortcut that automatically executes the propagated copies of the worm and a rootkit component responsible for hiding all malicious files and processes to prevent detection of Stuxnet. It is typically introduced to the target environment via an infected USB flash drive, thus crossing any air gap. The worm then propagates across the network, scanning for Simatic software on computers controlling a 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 Step7 software, modifying the code and giving unexpected commands to the PLC while returning a loop of normal operation system values back to the users.
The worm initially spreads indiscriminately, but includes a highly specialized malware payload that is designed to target only Siemens SCADA (SCADA) systems that are configured to control and monitor specific industrial processes. Stuxnet infects PLCs by subverting the WinCC software application that is used to reprogram these devices.
Different variants of Stuxnet targeted five Iranian organizations, with the probable target widely suspected to be Enriched uranium infrastructure in Iran; NortonLifeLock noted in August 2010 that 60 percent of the infected computers worldwide were in Iran. Siemens stated that the worm caused no damage to its customers, but the Iran nuclear program, which uses embargoed Siemens equipment procured secretly, was damaged by Stuxnet. Kaspersky Lab concluded that the sophisticated attack could only have been conducted "with nation-state support". F-Secure's chief researcher Mikko Hyppönen, when asked if possible nation-state support were involved, agreed: "That's what it would look like, yes."
In May 2011, 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 "we're glad they the are having trouble with their centrifuge machine and that we the U.S. and its allies are doing everything we can to make sure that we complicate matters for them", offering "winking acknowledgement" of United States involvement in Stuxnet. Gary Samore speaking at the 10 December 2010 Washington Forum of the Foundation for Defense of Democracies in Washington DC, reported by C-Span and contained in the PBS program Need to Know ( "Cracking the code: Defending against the superweapons of the 21st century cyberwar", 4 minutes into piece) 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 2012, an article in The New York Times reported that Stuxnet was 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.
On 24 July 2012, an article by Chris Matyszczyk from CNET reported that the Atomic Energy Organization of Iran e-mailed F-Secure's chief research officer Mikko Hyppönen to report a new instance of malware.
On 25 December 2012, an 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 malware targeted a power plant and some other industries in Hormozgan province in recent months.
According to Eugene Kaspersky, the worm also infected a nuclear power plant in Russia. Kaspersky noted, however, that since the power plant is not connected to the public Internet, the system should remain safe.
Kaspersky Lab experts initially estimated that Stuxnet began spreading around March or April 2010, but the first variant of the worm appeared in June 2009. On 15 July 2010, the day the worm's existence became widely known, a distributed denial-of-service attack targeted the servers of two leading mailing lists on industrial-systems security. This attack, from an unknown source but possibly related to Stuxnet, disabled one of the lists, interrupting a key information source for power plants and factories. Separately, researchers at NortonLifeLock uncovered a version of the Stuxnet computer virus that was used to attack Iran's nuclear program in November 2007, with evidence indicating it was under development as early as 2005, when Iran was still setting up its uranium enrichment facility.
The second variant, with substantial improvements, appeared in March 2010, reportedly due to concerns that Stuxnet was not spreading fast enough. A third variant, with minor improvements, followed in April 2010. The worm contains a component with a build timestamp from 3 February 2010. On 25 November 2010, Sky News in the United Kingdom reported receiving information from an anonymous source at an unidentified IT security organization claiming that Stuxnet, or a variation of the worm, had been traded on the black market.
In 2015, Kaspersky Lab reported that the Equation Group had used two of the same zero-day attacks prior to their use in Stuxnet, in another malware called fanny.bmp. Kaspersky Lab noted 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".
In 2019, Chronicle researchers Juan Andres Guerrero-Saade and Silas Cutler presented findings indicating that at least four distinct threat actor malware platforms collaborated in developing the different versions of Stuxnet. The collaboration was referred to as 'GOSSIP GIRL', a name derived from a threat group mentioned in classified CSE slides that included Flame. GOSSIP GIRL is described as a cooperative umbrella encompassing the Equation Group, Flame, Duqu, and Flowershop (also known as 'Cheshire Cat').
In 2020, researcher Facundo Muñoz presented findings suggesting that Equation Group may have collaborated with Stuxnet developers in 2009 by providing at least one zero-day exploit, and one exploit from 2008 that was actively used by the Conficker computer worm and Chinese hackers. In 2017, a group of hackers known as The Shadow Brokers leaked a collection of tools attributed to Equation Group, including new versions of both exploits compiled in 2010. Analysis of the leaked data indicated significant code overlaps, as both Stuxnet's exploits and Equation Group's exploits were developed using a set of libraries called the "Exploit Development Framework", also leaked by The Shadow Brokers.

Iran was reported to have fortified its cyberwar abilities following the Stuxnet attack, and has been suspected of retaliatory attacks against United States banks in Operation Ababil." Iran denies hacking into American banks " Reuters, 23 September 2012
For its targets, Stuxnet contains, among other things, code for a man-in-the-middle attack that fakes industrial process control sensor signals so an infected system does not shut down due to detected abnormal behavior. Such complexity is unusual for malware. The worm consists of a layered attack against three different systems:
The malware has both Protection ring rootkit ability under Windows, and its have been digitally signed with the private keys of two public key certificates that were stolen from separate well-known companies, JMicron and Realtek, both located at Hsinchu Science Park in Taiwan. The Code signing helped it install Protection ring rootkit drivers successfully without users being notified, and thus it remained undetected for a relatively long period of time. Both compromised certificates have been revoked by Verisign.
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. Both of these have subsequently been redirected by their DNS service provider to Dynadot as part of a global effort to disable the malware.
The malware also used a zero-day exploit in the WinCC/SCADA database software in the form of a hard-coded database password.
Stuxnet requires specific subordinate system to be attached to the targeted Siemens S7-300 controller system: variable-frequency drives (frequency converter drives) and its associated modules. It only attacks those PLC systems with variable-frequency drives from two specific vendors: Vacon based in Finland and Fararo Paya based in Iran. Furthermore, it monitors the frequency of the attached motors, and only attacks systems that spin between 807 Hertz and 1,210 Hz. This is a much higher frequency than motors typically operate at in most industrial applications, with the notable exception of . Stuxnet installs malware into memory block DB890 of the PLC that monitors the Profibus messaging bus of the system. When certain criteria are met, it periodically modifies the frequency to 1,410 Hz and then to 2 Hz and then to 1,064 Hz, and thus affects the operation of the connected motors by changing their rotational speed. It also installs a rootkit the first such documented case on this platform that hides the malware on the system and masks the changes in rotational speed from monitoring systems.
The worm's ability to reprogram external PLCs may complicate the removal procedure. Symantec's Liam O'Murchu warns that fixing Windows systems may not fully solve the infection; a thorough audit of PLCs may be necessary. Despite speculation that incorrect removal of the worm could cause damage, Siemens reports that in the first four months since discovery, the malware was successfully removed from the systems of 22 customers without any adverse effects.
The US Department of Homeland Security National Cyber Security Division (NCSD) operates the Control System Security Program (CSSP). The program operates a specialized computer emergency response team called the Industrial Control Systems Cyber Emergency Response Team (ICS-CERT), conducts a biannual conference (), provides training, publishes recommended practices, and provides a self-assessment tool. As part of a Department of Homeland Security plan to improve American computer security, in 2008 it and the Idaho National Laboratory (INL) worked with Siemens to identify security holes in the company's widely used Process Control System 7 (PCS 7) and its software Step 7. In July 2008, INL and Siemens publicly announced flaws in the control system at a Chicago conference; Stuxnet exploited these holes in 2009.
Several industry organizations and professional societies have published standards and best practice guidelines providing direction and guidance for control system end-users on how to establish a control system security management program. The basic premise that all of these documents share is that prevention requires a multi-layered approach, often termed defense in depth. The layers include policies and procedures, awareness and training, network segmentation, access control measures, physical security measures, system hardening, e.g., patch management, and system monitoring, anti-virus and intrusion prevention system (IPS). The standards and best practices also all recommend starting with a risk analysis and a control system security assessment.
In late December 2008, Dutch engineer Erik van Sabben travelled to Iran, allegedly to infiltrate the Natanz nuclear facility on behalf of Dutch intelligence and install equipment infected with Stuxnet. He died two weeks after the Stuxnet attack at age 36 in an apparent single-vehicle motorcycle accident in Dubai.
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.
The worm worked by first causing an infected Iranian IR-1 centrifuge to increase from its normal operating speed of 1,064 hertz to 1,410 hertz for 15 minutes before returning to its normal frequency. 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. 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.
According to The Washington Post, International Atomic Energy Agency (IAEA) cameras installed in the Natanz facility recorded the sudden dismantling and removal of approximately 900–1,000 centrifuges during the time the Stuxnet worm was reportedly active at the plant. Iranian technicians, however, were able to quickly replace the centrifuges and the report concluded that uranium enrichment was likely only briefly disrupted.
On 15 February 2011, the Institute for Science and International Security released a report concluding that:
The head of the Bushehr Nuclear Power Plant told Reuters that only the personal computers of staff at the plant had been infected by Stuxnet and the state-run newspaper Iran Daily quoted Reza Taghipour, Iran's telecommunications minister, as saying that it had not caused "serious damage to government systems". The Director of Information Technology Council at the Iranian Ministry of Industries and Mines, Mahmud Liaii, has said that: "An Cyberwarfare has been launched against Iran ... This computer worm is designed to transfer data about production lines from our industrial plants to locations outside Iran."
In response to the infection, Iran assembled a team to combat it. 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. 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.
According to Hamid Alipour, deputy head of Iran's government Information Technology Company, "The attack is still ongoing and new versions of this virus are spreading." He reported that his company had begun the cleanup process at Iran's "sensitive centres and organizations". "We had anticipated that we could root out the virus within one to two months, but the virus is not stable, and since we started the cleanup process three new versions of it have been spreading", he told the Islamic Republic News Agency on 27 September 2010.
On 29 November 2010, Iranian president Mahmoud Ahmadinejad stated for the first time that a computer virus had caused problems with the controller handling the centrifuges at its Natanz facilities. According to Reuters, he told reporters at a news conference in Tehran: "They succeeded in creating problems for a limited number of our centrifuges with the software they had installed in electronic parts."
On the same day two Iranian nuclear scientists were targeted in separate, but nearly simultaneous car bomb attacks near Shahid Beheshti University in Tehran. Majid Shahriari, a quantum physicist, was killed. Fereydoon Abbasi, a high-ranking official at the Ministry of Defense was seriously wounded. Wired speculated that the assassinations could indicate that whoever was behind Stuxnet felt that it was not sufficient to stop the nuclear program. That same Wired article suggested the Iranian government could have been behind the assassinations. In January 2010, another Iranian nuclear scientist, a physics professor at Tehran University, was killed in a similar bomb explosion. On 11 January 2012, a director of the Natanz nuclear enrichment facility, Mostafa Ahmadi Roshan, was killed in an attack quite similar to the one that killed Shahriari.
An analysis by the FAS demonstrates that Iran's enrichment capacity grew during 2010. The study indicated that Iran's centrifuges appeared to be performing 60% better than in the previous year, which would significantly reduce Tehran's time to produce bomb-grade uranium. The FAS report was reviewed by an official with the IAEA who affirmed the study.
European and US officials, along with private experts, told Reuters that Iranian engineers were successful in neutralizing and purging Stuxnet from their country's nuclear machinery.
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.
In 2009, a year before Stuxnet was discovered, Scott Borg of the United States Cyber-Consequences Unit (US-CCU) suggested that Israel may prefer to mount a cyberattack rather than a military strike on Iran's nuclear facilities. 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. So a tool like Stuxnet is Israel's obvious weapon of choice." Iran uses P-1 centrifuges at Natanz, the design for which A. Q. Khan stole in 1976 and took to Pakistan. His black market nuclear-proliferation network sold P-1s to, among other customers, Iran. 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. The equipment may be from the United States, which received P-1s from Libya's former nuclear program.
Some have also cited several clues in the code such as a concealed reference to the word MYRTUS, believed to refer to the Latin language name of the Myrtaceae tree, which in Hebrew is called hadassah. Hadassah was the birth name of the former Jewish queen of Persia, Queen Esther. However, it may be that the "MYRTUS" reference is simply a misinterpreted reference to SCADA components known as RTUs (Remote Terminal Units) and that this reference is actually "My RTUs"–a management feature of SCADA. 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. 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. Such data is not conclusive, since, as noted by Symantec, "attackers would have the natural desire to implicate another party".
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 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. Bumgarner pointed out that the centrifuges used to process fuel for nuclear weapons are a key target for cybertage operations and that they can be made to destroy themselves by manipulating their rotational speeds.
In a March 2012 interview with 60 Minutes, retired US Air Force General Michael Hayden who served as director of both the Central Intelligence Agency and National Security Agency while denying knowledge of who created Stuxnet said that he believed it had been "a good idea" but that it carried a downside in that it had legitimized the use of sophisticated cyber weapons designed to cause physical damage. Hayden said: "There are those out there who can take a look at this ... and maybe even attempt to turn it to their own purposes". 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. Speaking of the Stuxnet creators, he said: "They opened the box. They demonstrated the capability ... It's not something that can be put back."
A Wired magazine article about US General Keith B. Alexander stated: "And he and his cyber warriors have already launched their first attack. The cyber weapon that came to be known as Stuxnet was created and built by the NSA in partnership with the CIA and Israeli intelligence in the mid-2000s."
China, Jordan, and France are other possibilities, and Siemens may have also participated. Langner speculated that the infection may have spread from USB drives belonging to Russian contractors since the Iranian targets were not accessible via the Internet. In 2019, it was reported that an Iranian mole working for 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.
Sandro Gaycken from the Free University Berlin argued that the attack on Iran was a ruse to distract from Stuxnet's real purpose. According to him, its broad dissemination in more than 100,000 industrial plants worldwide suggests a field test of a cyber weapon in different security cultures, testing their preparedness, resilience, and reactions, all highly valuable information for a cyberwar unit.
The United Kingdom has denied involvement in the worm's creation.
In July 2013, Edward Snowden claimed that Stuxnet was cooperatively developed by the United States and Israel.
Alex Gibney's 2016 documentary Zero Days covers the phenomenon around Stuxnet. A zero-day (also known as 0-day) vulnerability is a computer-software vulnerability that is unknown to, or unaddressed by, those who should be interested in mitigating the vulnerability (including the vendor of the target software). Until the vulnerability is mitigated, hackers can exploit it to adversely affect computer programs, data, additional computers or a network.
In 2016, it was revealed that General James Cartwright, the former head of the U.S. Strategic Command, had leaked information related to Stuxnet. He later pleaded guilty for lying to FBI agents pursuing an investigation into the leak. On 17 January 2017, he was granted a full pardon in this case by President Obama, thus expunging his conviction.
Iranian reaction
The Associated Press reported that the semi-official Iranian Students News Agency released a statement on 24 September 2010 stating that experts from the Atomic Energy Organization of Iran met in the previous week to discuss how Stuxnet could be removed from their systems. According to analysts, such as David Albright, Western intelligence agencies had been attempting to sabotage the Iranian nuclear program for some time.
Israel
Israel, through Unit 8200, has been speculated to be the country behind Stuxnet in multiple media reports and by experts such as Richard A. Falkenrath, former Senior Director for Policy and Plans within the US Office of Homeland Security. Yossi Melman, who covers intelligence for Israeli newspaper Haaretz and wrote a book about Israeli intelligence, also suspected that Israel was involved, noting that Meir Dagan, the former (up until 2011) head of the national intelligence agency Mossad, had his term extended in 2009 because he was said to be involved in important projects. Additionally, in 2010 Israel grew to expect that Iran would have a nuclear weapon in 2014 or 2015 at least three years later than earlier estimates without the need for an Israeli military attack on Iranian nuclear facilities; "They seem to know something, that they have more time than originally thought", he added. 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. When questioned whether Israel was behind the virus in the fall of 2010, some Israeli officials broke into "wide smiles", fueling speculation that the government of Israel was involved with its genesis. American presidential advisor Gary Samore also smiled when Stuxnet was mentioned, although American officials have suggested that the virus originated abroad. According to The Telegraph, Israeli newspaper Haaretz reported that a video celebrating operational successes of Gabi Ashkenazi, retiring Israel Defense Forces (IDF) Chief of Staff, was shown at his retirement party and included references to Stuxnet, thus strengthening claims that Israel's security forces were responsible.
United States
There has also been reports on the involvement of the United States and its collaboration with Israel, with one report stating that "there is vanishingly little doubt that it played a role in creating the worm". It has been reported that the United States, under one of its most secret programs, initiated by the Bush administration and accelerated by the Obama administration, has sought to destroy Iran's nuclear program by novel methods such as undermining Iranian computer systems. A leaked diplomatic cable showed how the United States was advised to target Iran's nuclear abilities through 'covert sabotage'. An article in The New York Times in January 2009 credited a then-unspecified program with preventing an Israeli military attack on Iran where some of the efforts focused on ways to destabilize the centrifuges. A Wired article claimed that Stuxnet "is believed to have been created by the United States". Dutch historian Peter Koop speculated that the Tailored Access Operations could have developed Stuxnet, possibly in collaboration with Israel.
Joint effort and other states and targets
In April 2011, Iranian government official Gholam Reza Jalali stated that an investigation had concluded that the United States and Israel were behind the Stuxnet attack. Frank Rieger stated that three European countries' intelligence agencies agreed that Stuxnet was a joint United States-Israel effort. The code for the Windows injector and the PLC payload differ in style, likely implying collaboration. Other experts believe that a US-Israel cooperation is unlikely because "the level of trust between the two countries' intelligence and military establishments is not high".
Deployment in North Korea
According to a report by Reuters, the NSA also tried to sabotage North Korea's nuclear program using a version of Stuxnet. The operation was reportedly launched in tandem with the attack that targeted Iranian centrifuges in 2009–10. The North Korean nuclear program shares a number of similarities with the Iranian, both having been developed with technology transferred by Pakistani nuclear scientist A.Q. Khan. The effort failed, however, because North Korea's extreme secrecy and isolation made it impossible to introduce Stuxnet into the nuclear facility.
Stuxnet 2.0 cyberattack
In 2018, Gholamreza Jalali, Iran's chief of the National Organization for Passive Defense, claimed that his country fended off a Stuxnet-like attack targeting the country's telecom infrastructure. Iran's Telecommunications minister, Mohammad-Javad Azari Jahromi has since accused Israel of orchestrating the attack. Iran plans to sue Israel through the International Court of Justice (ICJ) and is also willing to launch a retaliation attack if Israel does not desist.
Related malware
"Stuxnet's Secret Twin"
A November 2013 article in Foreign Policy magazine claims existence of an earlier, much more sophisticated attack on the centrifuge complex at Natanz, focused on increasing centrifuge failure rate over a long time period by stealthily inducing uranium hexafluoride gas overpressure incidents. This malware was capable of spreading only by being physically installed, probably by previously contaminated field equipment used by contractors working on Siemens control systems within the complex. It is not clear whether this attack attempt was successful, but follow-up by a different, simpler, and more conventional attack is indicative that it was not.
Duqu
On 1 September 2011, a new worm was found, thought to be related to Stuxnet. The Laboratory of Cryptography and System Security (CrySyS) of the Budapest University of Technology and Economics analyzed the malware, naming the threat Duqu. NortonLifeLock, based on this report, continued the analysis of the threat, calling it "nearly identical to Stuxnet, but with a completely different purpose", and published a detailed technical paper. The main component used in Duqu is designed to capture information such as keystrokes and system information. The exfiltrated data may be used to enable a future Stuxnet-like attack. On 28 December 2011, Kaspersky Lab's director of global research and analysis spoke to Reuters about recent research results showing that the platform Stuxnet and Duqu both originated in 2007, and is being referred to as Tilded due to the ~d at the beginning of the file names. Also uncovered in this research was the possibility for three more variants based on the Tilded platform.
Flame
In May 2012, the new malware "Flame" was found, thought to be related to Stuxnet. Researchers named the program "Flame" after the name of one of its modules. After analysing the code of Flame, Kaspersky Lab said that there is a strong relationship between Flame and Stuxnet. An early version of Stuxnet contained code to propagate infections via USB drives that is nearly identical to a Flame module that exploits the same vulnerability.
Media coverage
Since 2010, there has been extensive international media coverage on Stuxnet and its aftermath. In early commentary, The Economist pointed out that Stuxnet was "a new kind of cyber-attack". On 8 July 2011, Wired then published an article detailing how network security experts were able to decipher the origins of Stuxnet. In that piece, Kim Zetter claimed that Stuxnet's "cost–benefit ratio is still in question". Later commentators tended to focus on the strategic significance of Stuxnet as a cyber weapon. Following the Wired piece, Holger Stark called Stuxnet the "first digital weapon of geopolitical importance, it could change the way wars are fought". Meanwhile, Eddie Walsh referred to Stuxnet as "the world's newest high-end asymmetric threat". Ultimately, some claim that the "extensive media coverage afforded to Stuxnet has only served as an advertisement for the vulnerabilities used by various cybercriminal groups". While that may be the case, the media coverage has also increased awareness of cyber security threats.
In popular culture
Besides the aforementioned Alex Gibney documentary Zero Days (2016), which looks into the malware and the cyberwarfare surrounding it, other works which reference Stuxnet include:
