IRANIAN CYBER ATTACKS ON THE US AND ISRAEL

By Harretz-Human Synthesis-12 March 2026

Here is a clear overview of the most recent cyberattacks and cyber-warfare activity affecting the United States and Israel (mainly in early March 2026). Much of it is tied to the ongoing conflict involving Iran, the U.S., and Israel, where hacking is being used alongside traditional military operations.

1. Iranian-linked cyberattack on a U.S. medical company. One of the most reported recent incidents targeted Stryker, a major U.S. medical technology company. A pro-Iranian hacking group claimed responsibility for the attack. Hackers reportedly stole tens of terabytes of company data and disrupted internal systems. The attackers said it was retaliation for U.S.–Israeli strikes on Iran. Healthcare companies are increasingly targeted because hospitals rely heavily on digital infrastructure. Why it matters:Healthcare cyberattacks can potentially affect patient care, hospital systems, and sensitive medical data.

2. Large surge of “hacktivist” attacks worldwide. Cybersecurity researchers reported a wave of politically motivated hacking after the conflict escalated. 149 DDoS attacks were recorded against 110 organizations in 16 countries. Targets included government sites, defense companies, and infrastructure linked to Israel and its allies. Many attacks were carried out by loosely organized hacktivist groups rather than formal state military units. Typical tactics:Website shutdowns (DDoS attacks)Website defacements. Data leaks. Disinformation campaigns.

3. Cyberwar between Israel, the U.S., and Iran. The current conflict includes active cyber operations from both sides. U.S. and Israeli cyber operations disrupting Iranian military command systems before airstrikes. Hacking Iranian digital infrastructure (apps, broadcasting systems). Accessing traffic cameras and communications networks inside Iran. Iranian and pro-Iran hacker activity targeting U.S. companies and Israeli infrastructure. Conducting DDoS attacks, phishing campaigns, and propaganda operations. Iran is believed to rely heavily on Proxy hacker groups rather than purely state-run attacks.

4. Israeli targets and cyber threats. Israel has historically been one of the most targeted countries for cyberattacks due to regional conflicts. In 2025 it was the #1 country targeted by geopolitically motivated cyberattacks globally. Conflicts with Hamas, Iran, and allied groups have driven waves of hacktivist activity. Common targets in Israel:Energy companies. Government agencies. Media and communication networks. Transportation systems.

5. Hacker groups involved several politically motivated groups have been active in attacks on Israel and U.S. Allies: Dark Storm Team – pro-Palestinian group known for large DDoS campaigns against Israel and NATO supporters. Handala Hack – linked to Iranian intelligence according to security researchers. Various Iran-aligned hacktivist collectives and proxy actors. Many attacks are symbolic disruptions rather than large-scale infrastructure destruction, but experts warn escalation is possible.

6. Why cyberattacks are increasing. Experts say cyberwar is now a key part of modern conflicts: Reasons: Cheaper than conventional warfare. Harder to attribute to a specific country. Can disrupt infrastructure without physical combat. Useful for propaganda and psychological warfare. Security analysts expect continued attacks on U.S. and Israeli companies, banks, and infrastructure during the conflict.

Summary

Recent cyber incidents tied to the conflict include:Iranian-linked hackers attacking U.S. healthcare company Stryker. And of hacktivist attacks targeting Western and Israeli organizations.Cyber operations by Israel and the U.S. against Iranian systems?Ongoing digital attacks by Iranian-aligned hacker groups.

Together they show that the conflict is being fought both physically and digitally.
