The private email account of a U.S. intelligence official has purportedly been hacked, Foreign Policy is reporting.

A hacker calling himself “Johnnie Walker” sent an email Tuesday morning alleging to have hacked emails from the unnamed official’s account.

“The U.S. State Department officer’s email has been hacked,” the email stated, according to Foreign Policy. Attached to it was a trove of personal emails belonging to a Gmail account of the official, whose name was withheld from the report.

The official is said to specialize in matters related to Russia at the State Department’s Bureau of Intelligence and Research, a member of the intelligence community that aims to use intelligence to serve U.S. diplomatic efforts.

The unknown hacker claimed that the emails included contacts between the official and other intelligence officials, including those with the CIA.

The State Department would not comment on the specific incident when contacted by Foreign Policy, a spokesman saying only that the department is “aware that malicious actors often target email accounts of government and business leaders across the United States.”

The report comes as concerns continue to mount over Russia’s meddling in the 2016 presidential election, an effort that the U.S. intelligence community says included hacking email accounts associated with the Democratic National Committee and Democratic nominee Hillary Clinton Hillary Diane Rodham ClintonJeff Flake: Republicans 'should hold the same position' on SCOTUS vacancy as 2016 Momentum growing among Republicans for Supreme Court vote before Election Day Warning signs flash for Lindsey Graham in South Carolina MORE's campaign chairman, John Podesta.

Podesta gave hackers access to his email by falling victim to a phishing scam.

Moscow’s meddling, which also included attempts to access election-related systems in nearly two dozen states, has raised alarm among lawmakers that foreign nations could try to use cyberattacks to interfere in future elections.
