RYE BROOK, N.Y. (CBSNewYork) — A new report states that a dam in Westchester County was infiltrated by Iranian hackers in 2013.

The Wall Street Journal reported in its Sunday issue that hackers gained access to the Bowman Avenue Dam in Rye Brook through a cellular modem and used their access to probe the dam’s system.

The WSJ reports that government intelligence agencies noticed the breach while conducting a broader investigation of computers believed to be linked to Iranian hackers.

The details of the breach still remain classified, the WSJ reported.

The discovery has raised concerns about the overarching issues regarding cybersecurity and digital warfare, targeted toward large-scale infrastructure systems that may still be running on outdated technology with vulnerable systems.

According to the Rye Daily Voice, Rye City Manager Marcus Serrano stated the city cooperated with an U.S. Department of Homeland Investigation into the incident in 2013.

On Monday, Manhattan District Attorney Cyrus R. Vance pushed for speedier legislation efforts on allowing law enforcement to have access to encrypted app data for use in targeting crime.

“iPhones are now the first consumer products in American history that are beyond the reach of lawful warrants,” Vance said in a statement. “The result is crimes go unsolved and victims are left beyond the protection of law.”

Vance’s comments came in response to Apple CEO Tim’s Cook’s vocal support of keeping encrypted information used on Apple products — like iPhone and iPads — shielded from government accessibility.
