Iranian hackers have targeted not only US water systems but also telecommunications, energy and other infrastructure in recent weeks, NBC News reported on Wednesday, citing four people with access to government and industry cyberthreat information.
The attempted cyberattacks focused on automated systems connected to the internet and have so far been unsuccessful, the report said.
A Telegram channel presenting itself as a voice for Iranian cyber operations also threatened attacks on US infrastructure.
“Soon, the United States will witness unexpected and critical events in the energy, water, and telecommunications industries,” the group, APT IRAN, said on Telegram, according to NBC News.
The channel provided no evidence of successful cyber operations against the United States.
The FBI said last month it was investigating cyberattacks on municipal water systems in at least seven states. NBC News previously reported those attacks were most likely carried out by Iranian hackers. They caused no major disruptions or water contamination.
US cybersecurity officials have also warned that Iranian hackers were trying to break into internet-connected industrial control systems and urged critical infrastructure operators to strengthen their defenses.
NBC News said the recent attempts were technically unsophisticated but could still pose risks because some infrastructure operators rely on basic internet-connected equipment.
The US Cybersecurity and Infrastructure Security Agency did not respond to NBC News’ request for comment. The White House referred questions to the FBI, which did not respond, while the CIA declined to comment.
