Cyberwarfare and Iran

Iran has been the target of cyberattacks, including the Operation Olympic Games (Stuxnet) attack by the United States and Israel on its nuclear facilities.

According to a 2014 report by Institute for National Security Studies, Iran is "one of the most active players in the international cyber arena". In 2013, a Revolutionary Guards general stated that Iran has "the 4th biggest cyber power among the world's cyber armies." According to a 2021 report by a cyber-security company, "Iran is running two surveillance operations in cyber-space, targeting more than 1,000 dissidents". As of 2024, Iran's cyber activities have advanced, particularly in their precision and intelligence-gathering capabilities, allowing for more accurate and targeted attacks against Israel. Following directives from Iran's supreme leader Ali Khamenei after the 7 October attacks, cyber operations expanded, including joint efforts with Hezbollah. Despite these advances, Iran's cyber capabilities still fall short of Israel's, with Iranian hackers' skills being likened to those of mid-level organized crime gangs. However, Israeli officials remain concerned that Iran could rapidly enhance its capabilities, particularly through potential cooperation with Russia. Iranian cyberwarfare targeted the US during the 2026 Iran war, with researchers noting that Iran's capabilities were more advanced and aggressive during this period.

Background

Cyberwarfare is the use of cyberattacks against an enemy state, causing comparable harm to traditional warfare. Some intended outcomes could be espionage, sabotage, propaganda, manipulation, or economic warfare.

Many countries, including the United States, United Kingdom, Russia, China, Israel, Iran, India, and North Korea, have active cyber capabilities for offensive and defensive operations. As states explore the use of cyber operations and combine capabilities, the likelihood of physical confrontation and violence playing out as a result of, or part of, a cyber operation is increased. However, meeting the scale and protracted nature of war is unlikely, thus ambiguity remains.

There has been significant debate among experts regarding the definition of cyberwarfare, and even if such a thing exists. One view is that the term is a misnomer, since no cyberattack to date could be described as a war. An alternative view is that it is a suitable label for cyberattacks that cause physical damage to people and objects in the real world.

The first instance of kinetic military action used in response to a cyberattack resulting in the loss of human life was observed on 5 May 2019, when the Israel Defense Forces targeted and destroyed a building associated with an ongoing cyberattack.

Attacks against Iran

In June 2010, Iran was the victim of a cyber-attack when its nuclear facility in Natanz was infiltrated by the cyber-worm 'Stuxnet'. A combined effort by the United States and Israel, Stuxnet destroyed perhaps over 1,000 nuclear centrifuges and, according to a Business Insider article, "[set] Tehran's atomic programme back by at least two years." The worm spread beyond the plant to allegedly infect over 60,000 computers, but the government of Iran indicates it caused no significant damage. Iran crowdsourced solutions to the worm and is purportedly now better positioned in terms of cyber warfare technology. No government claimed responsibility for the worm. The cyber-worm was also used against North Korea.

In November 2024 ClearSky revealed an Iranian "dream job malware" APT TA455 doing an op using North Korean shared methods targeting US defence sector.

Iranian state-sponsored hackers, identified as TA455 (also known as APT35 and Charming Kitten), have been conducting a cyber espionage campaign targeting the aerospace industry since September 2023, using tactics similar to those of North Korean threat actors. The campaign involves creating fake recruiter profiles on LinkedIn and using malicious domains to lure victims into downloading malware known as SnailResin. Victims are enticed to open ZIP files disguised as job-related documents, which have a low antivirus detection rate. The malware is deployed through DLL side-loading attacks, closely mirroring techniques used by North Korean hackers. Researchers suggest that the Iranian hackers may have adopted these methods from North Korea, particularly given the malware's initial association with North Korean groups like Kimsuky and Lazarus. TA455 employs Cloudflare to obscure its command-and-control domains and encodes command and control data on GitHub to blend in with legitimate web traffic, making tracking their infrastructure difficult. The primary targets of this campaign are aerospace professionals, with the goal of infiltrating networks within the aerospace, aviation, and defense sectors, particularly in the Middle East, including Israel, the UAE, and potentially Turkey, India, and Albania. The goal appears to be espionage and data exfiltration from these high-value targets in the aerospace sector.

The UK and US have jointly issued a warning about ongoing spear-phishing attacks conducted by cyber actors affiliated with Iran's Islamic Revolutionary Guard Corps (IRGC). These sophisticated attacks target individuals connected to Iranian and Middle Eastern affairs, including government officials, think tank personnel, journalists, activists, and those involved in US political campaigns. The attackers use social engineering techniques to impersonate trusted contacts, aiming to gain access to victims' personal and business accounts. They often use fraudulent login pages to obtain credentials, allowing them to access sensitive information and manipulate email accounts. The National Cyber Security Centre (NCSC) and its US counterparts are urging at-risk individuals to follow mitigation steps and utilize free cyber defence services to protect themselves. Paul Chichester, NCSC Director of Operations, emphasized the persistent nature of this threat and the importance of remaining vigilant, particularly for those in sensitive sectors.
