Iranian hackers have attempted to penetrate energy, telecommunications, and critical infrastructure networks across the United States in recent weeks, NBC News reported Wednesday, citing four sources with direct access to government and industry threat intelligence.
According to officials, they detected and neutralized the intrusion attempts in time, causing no physical or operational damage to the targeted utilities.

According to four sources who spoke with NBC News, Tehran’s cyber operations are no longer confined to regional water utilities, marking a deliberate expansion to establish footholds across strategic national infrastructure. The sources stressed that they repelled the intercepted intrusions before the attackers could disrupt operations or inflict system-wide damage.
The revelations coincide with an explicit public threat issued by the hacking group “APT IRAN,” reportedly linked to the IRGC-affiliated cyber wing “CyberAv3ngers”.
The group warned that the United States should expect “unexpected and critical events across the energy, water, and telecommunications sectors.”

In their declaration, the hackers claimed that the recent wave of cyber strikes against American water networks was intended “to serve as a warning and demonstrate the capability to strike American infrastructure.”
The group further threatened it could disrupt electrical grids, communications, and water distribution at will.
Cybersecurity experts, however, emphasize that these threats largely constitute psychological warfare and bluster rather than verified operational control over sensitive industrial systems.The expanded targeting follows a sustained cyber campaign against municipal water facilities in the United States.
In late July, the FBI and the U.S. Environmental Protection Agency (EPA) revealed that water utilities across at least seven states reported cyber incidents—some of which resulted in localized operational disruptions—with subsequent evidence pointing to Iranian involvement across additional facilities.
The findings highlight Tehran’s strategic intent to open an expansive cyber front against the American home front: shifting from opportunistic intrusions into local municipal utilities to directly probing the central arteries of the U.S. economy—power and communications—while challenging federal defensive postures amid rising geopolitical friction.
