According to a report from CNN, the Obama administration plans to publicly blame Iran for the 2013 hack on a New York dam.
The Wall Street Journal reported the 2013 hack on the dam in suburban Rye, New York, at the end of 2015. The report attributed the security breach to Iranian hackers.
"Was this a dress rehearsal for something larger? It also makes me concerned about the security of our infrastructure that is significantly more critical than the Bowman Avenue Dam," the mayor of Rye Brook, New York, said.
The hack brought attention to outdated computer systems used to control not just dams, but other infrastructure in the U.S. like bridges, pipelines and factories.
The Department of Justice hasn't commented on the reported announcement, but it did say in a statement to media outlets that it takes "malicious activity in cyberspace seriously."
