The U.S. Department of Homeland Security (DHS) has issued a warning about the potential for cyber attacks from pro-Iranian hacking groups, following recent military actions targeting nuclear facilities in Iran.

In an official bulletin, DHS stated that the ongoing conflict in the Middle East has created a “heightened threat environment” within the United States. As tensions rise, both government-affiliated and independent pro-Iranian cyber actors may increase their focus on U.S. digital infrastructure.

According to the bulletin, “low-level cyber attacks against U.S. networks by pro-Iranian hacktivists are likely,” with the possibility of more sophisticated operations carried out by state-linked actors. These groups have previously been known to exploit vulnerabilities in poorly secured networks and internet-connected systems to carry out disruptive activities.

The warning follows recent airstrikes conducted on key nuclear facilities in Iran, contributing to a broader conflict that has extended into cyberspace. Hacktivist collectives on both sides of the conflict have reportedly engaged in retaliatory actions online, targeting platforms and services associated with opposing nations.

Cybersecurity professionals and infrastructure operators are advised to remain vigilant, implement robust security measures, and monitor for any signs of suspicious activity.
