Ethical Hacking News
The U.S. government has warned of ongoing Iranian cyber threats to critical infrastructure, with attacks likely to escalate due to recent events. These hackers typically exploit outdated software, known vulnerabilities, and weak or default passwords on internet-connected systems. The 2025 Iran-Israel war has sparked a heightened threat environment in the United States, with low-level cyber attacks against U.S. networks by pro-Iranian hacktivists likely and potentially more severe attacks by Iranian government-affiliated actors.

The threat of Iranian cyber warfare continues to escalate, posing a significant risk to critical infrastructure and national security. Iranian state-linked hackers are actively targeting U.S. critical infrastructure and other sensitive systems with malicious intent. The use of outdated software, weak or default passwords, and exploitation of known vulnerabilities are common tactics employed by these hackers. A heightened threat environment in the United States has been sparked due to the 2025 Iran-Israel war, potentially leading to more severe cyber attacks. Recent U.S. attacks tied to anti-Semitic views suggest a rising concern about violent extremists mobilizing in response to the conflict. The U.S. Department of Homeland Security had issued warnings about the possibility of cyber-attacks launched by Iranian threat actors before the 2025 Iran-Israel war. U.S. critical infrastructure operators must take proactive measures to strengthen their defenses against evolving threats, including disconnecting OT systems from the internet and applying software updates.
The world is on high alert as the threat of Iranian cyber warfare continues to escalate, posing a significant risk to critical infrastructure and national security. According to recent warnings from U.S. cybersecurity and intelligence agencies, including the Cybersecurity and Infrastructure Security Agency (CISA), Federal Bureau of Investigation (FBI), Department of Defense Cyber Crime Center (DC3), and National Security Agency (NSA), Iranian state-linked hackers are actively targeting U.S. critical infrastructure and other sensitive systems with malicious intent.
These cyber threats are not limited to the United States, as Iranian-affiliated cyber actors have been known to conduct attacks on Israeli entities, affecting various sectors such as water, energy, and healthcare. The use of outdated software, weak or default passwords, and exploitation of known vulnerabilities are common tactics employed by these hackers to gain unauthorized access to internet-connected systems.
The 2025 Iran-Israel war has sparked a heightened threat environment in the United States, with low-level cyber attacks against U.S. networks by pro-Iranian hacktivists likely and potentially more severe attacks by Iranian government-affiliated actors. This recent escalation in tensions between Iran and Israel may fuel extremist violence in the United States, especially if Iranian leaders issue a religious call for retaliation.
Recent U.S. attacks tied to anti-Semitic views suggest that the threat of more homeland plots is rising, indicating a growing concern about the potential for violent extremists in the Homeland independently mobilizing to violence in response to the conflict. Furthermore, Iran has shown its commitment to targeting U.S. officials linked to a 2020 military commander's death.
In January 2020, the U.S. Department of Homeland Security (DHS) issued other warnings about the possibility of cyber-attacks launched by Iranian threat actors. The attacks could have been the response of Tehran after Maj. Gen. Qassim Suleimani was killed by a U.S. drone airstrike at the Baghdad airport in Iraq.
The order to kill Soleimani was issued by President Trump, who said Soleimani was planning an "imminent" attack on US personnel in Baghdad. Christopher C. Krebs, who was the Director of Cybersecurity and Infrastructure Security Agency (CISA) at the time, warned of a potential new wave of cyber attacks carried out by Iran-linked hacker groups targeting U.S. assets.
Krebs warned operators of critical infrastructure to remain vigilant because the risk of cyber attacks is increasing hour by hour. The DHS issued a new National Terrorism Advisory System bulletin, adding that Iran has cyber capabilities to carry out attacks against US infrastructure, and it is also warned that Iran can conduct operations in the United States.
Given these escalating threats, it is imperative for U.S. critical infrastructure operators to take proactive measures to strengthen their defenses. This includes disconnecting OT and industrial control systems from the internet, using strong passwords, applying software updates, and enabling phishing-resistant multifactor authentication.
Furthermore, recent incidents such as the Ahold Delhaize data breach affecting over 2.2 million individuals and the Canadian ban on Hikvision over national security concerns highlight the need for robust cybersecurity measures to protect sensitive systems and data.
In conclusion, the threat of Iranian cyber warfare poses a significant risk to critical infrastructure and national security, with low-level attacks by pro-Iranian hacktivists and possible state-linked cyber activity likely. It is essential that U.S. organizations take proactive measures to strengthen their defenses against these evolving threats.
