The Washington Post has corrected a story that originally said Russian hackers penetrated the U.S. electric grid by breaching a utility company in Vermont.

“An earlier version of this story incorrectly said that Russian hackers had penetrated the U.S. electric grid. Authorities say there is no indication of that so far. The computer at Burlington Electric that was hacked was not attached to the grid,” an editor's note attached to the original article said.

The original story was published Friday, one day after the Obama administration announced new sanctions against Russia for its cyber activities.

According to the report, which cited anonymous senior administration officials, a code linked to the Grizzly Steppe operation was found within the utility's system.

Officials told the newspaper that the breach did not interrupt electrical operations.

Gov. Peter Shumlin (D-Vt.) called for “ a full and complete investigation of this incident" and to "undertake remedies to ensure that this never happens again,” according to the report.
