Cyberwarfare
The statement falsely reported normal business was resumed on 25 August 2012. However a Middle Eastern journalist leaked photographs taken on 1 September 2012 showing kilometers of petrol trucks unable to be loaded due to backed business systems still inoperable. 

On 29 August 2012 the same attackers behind Shamoon posted another pastie on PasteBin.com, taunting Saudi Aramco with proof they still retained access to the company network. The post contained the username and password on security and network equipment and the new password for the CEO Khalid Al- Falih The attackers also referenced a portion of the Shamoon malware as further proof in the pastie.
According to Kubecka, in order to restore operations. Saudi Aramco used its large private fleet of aircraft and available funds to purchase much of the world's hard drives, driving the price up. New hard drives were required as quickly as possible so oil prices were not affected by speculation. By 1 September 2012 gasoline resources were dwindling for the public of Saudi Arabia 17 days after the 15 August attack. RasGas was also affected by a different variant, crippling them in a similar manner.

Qatar: In March 2018 American Republican fundraiser Elliott Broidy filed a lawsuit against Qatar, alleging that Qatar's government stole and leaked his emails in order to discredit him because he was viewed "as an impediment to their plan to improve the country's standing in Washington." In May 2018, the lawsuit named Mohammed bin Hamad bin Khalifa Al Thani, brother of the Emir of Qatar, and his associate Ahmed Al-Rumaihi, as allegedly orchestrating Qatar's cyber warfare campaign against Broidy. Further litigation revealed that the same cybercriminals who targeted Broidy had targeted as many as 1,200 other individuals, some of whom are also "well-known enemies of Qatar" such as senior officials of the U.A.E., Egypt, Saudi Arabia, and Bahrain. While these hackers almost always obscured their location, some of their activity was traced to a telecommunication network in Qatar.

United Arab Emirates: The United Arab Emirates has launched several cyber-attacks in the past targeting dissidents. Ahmed Mansoor, an Emirati citizen, was jailed for sharing his thoughts on Facebook and Twitter. He was given the code name Egret under the state-led covert project called Raven, which spied on top political opponents, dissidents, and journalists. Project Raven deployed a secret hacking tool called Karma, to spy without requiring the target to engage with any web links.
In September 2021, three of the former American intelligence officers, Marc Baier, Ryan Adams, and Daniel Gericke, admitted to assisting the UAE in hacking crimes by providing them with advanced technology and violating US laws. Under a three-year deferred prosecution agreement with the Justice Department, the three defendants also agreed to pay nearly $1.7 million in fines to evade prison sentences. The court documents revealed that the Emirates hacked into the computers and mobile phones of dissidents, activists, and journalists. They also attempted to break into the systems of the US and rest of the world.

North America: 

United States: Cyberwarfare in the United States is a part of the American military strategy of proactive cyber defence and the use of cyberwarfare as a platform for attack. The new United States military strategy makes explicit that a cyberattack is casus belli just as a traditional act of war.
U.S. government security expert Richard A. Clarke, in his book Cyber War (May 2010), had defined "cyberwarfare" as "actions by a nation-state to penetrate another nation's computers or networks for the purposes of causing damage or disruption.": 6  The Economist describes cyberspace as "the fifth domain of warfare," and William J. Lynn, U.S. Deputy Secretary of Defense, states that "as a doctrinal matter, the Pentagon has formally recognized cyberspace as a new domain in warfare . . . [which] has become just as critical to military operations as land, sea, air, and space."
When Russia was still a part of the Soviet Union in 1982, a portion of a Trans-Siberia pipeline within its territory exploded, allegedly due to a Trojan Horse computer malware implanted in the pirated Canadian software by the Central Intelligence Agency. The malware caused the SCADA system running the pipeline to malfunction. The "Farewell Dossier" provided information on this attack, and wrote that compromised computer chips would become a part of Soviet military equipment, flawed turbines would be placed in the gas pipeline, and defective plans would disrupt the output of chemical plants and a tractor factory. This caused the "most monumental nonnuclear explosion and fire ever seen from space." However, the Soviet Union did not blame the United States for the attack.
In 2009, president Barack Obama declared America's digital infrastructure to be a "strategic national asset," and in May 2010 the Pentagon set up its new U.S. Cyber Command (USCYBERCOM), headed by General Keith B. Alexander, director of the National Security Agency (NSA), to defend American military networks and attack other countries' systems. The EU has set up ENISA (European Union Agency for Network and Information Security) which is headed by Prof. Udo Helmbrecht and there are now further plans to significantly expand ENISA's capabilities. The United Kingdom has also set up a cyber-security and "operations centre" based in Government Communications Headquarters (GCHQ), the British equivalent of the NSA. In the U.S. however, Cyber Command is only set up to protect the military, whereas the government and corporate infrastructures are primarily the responsibility respectively of the Department of Homeland Security and private companies.
On 19 June 2010, United States Senator Joe Lieberman (I-CT) introduced a bill called "Protecting Cyberspace as a National Asset Act of 2010", which he co-wrote with Senator Susan Collins (R-ME) and Senator Thomas Carper (D-DE). If signed into law, this controversial bill, which the American media dubbed the "Kill switch bill", would grant the president emergency powers over parts of the Internet. However, all three co-authors of the bill issued a statement that instead, the bill "[narrowed] existing broad presidential authority to take over telecommunications networks".
In August 2010, the U.S. for the first time warned publicly about the Chinese military's use of civilian computer experts in clandestine cyber attacks aimed at American companies and government agencies. The Pentagon also pointed to an alleged China-based computer spying network dubbed GhostNet which was revealed in a 2009 research report.
On 6 October 2011, it was announced that Creech AFB's drone and Predator fleet's command and control data stream had been keylogged, resisting all attempts to reverse the exploit, for the past two weeks. The Air Force issued a statement that the virus had "posed no threat to our operational mission".
On 21 November 2011, it was widely reported in the U.S. media that a hacker had destroyed a water pump at the Curran-Gardner Township Public Water District in Illinois. However, it later turned out that this information was not only false, but had been inappropriately leaked from the Illinois Statewide Terrorism and Intelligence Center.
In June 2012 the New York Times reported that president Obama had ordered the cyber attack on Iranian nuclear enrichment facilities.
In August 2012, USA Today reported that the US conducted cyberattacks for tactical advantage in Afghanistan.
According to a 2013 Foreign Policy magazine article, NSA's Tailored Access Operations (TAO) unit "has successfully penetrated Chinese computer and telecommunications systems for almost 15 years, generating some of the best and most reliable intelligence information about what is going on inside the People's Republic of China."
In 2014, Barack Obama ordered an intensification of cyberwarfare against North Korea's missile program for sabotaging test launches in their opening seconds. 
On 24 November 2014, Sony Pictures Entertainment hack was a release of confidential data belonging to Sony Pictures Entertainment (SPE).
In 2016 President Barack Obama authorized the planting of cyber weapons in Russian infrastructure in the final weeks of his presidency in response to Moscow's interference in the 2016 presidential election. On 29 December 2016 United States imposed the most extensive sanctions against Russia since the Cold War, expelling 35 Russian diplomats from the United States.
Economic sanctions are the most frequently used the foreign policy instruments by the United States today Thus, it is not surprising to see that economic sanctions are also used as counter policies against cyberattacks. According to Onder (2021), economic sanctions are also information gathering mechanisms for the sanctioning states about the capabilities of the sanctioned states.
In March 2017, WikiLeaks published more than 8,000 documents on the CIA. The confidential documents, codenamed Vault 7 and dated from 2013 to 2016, include details on CIA's software capabilities, such as the ability to compromise cars, smart TVs, web browsers (including Google Chrome, Microsoft Edge, Mozilla Firefox, and Opera Software ASA), and the operating systems of most smartphones (including Apple's iOS and Google's Android), as well as other operating systems such as Microsoft Windows, macOS, and Linux.
In June 2019, the New York Times reported that American hackers from the United States Cyber Command planted malware potentially capable of disrupting the Russian electrical grid.
