(NBC NEWS) WASHINGTON — The cybersecurity company FireEye says in a new report to private clients, obtained exclusively by NBC News, that hackers linked to North Korea recently targeted U.S. electric power companies with spearphishing emails.

The emails used fake invitations to a fundraiser to target victims, FireEye said. A victim who downloaded the invitation attached to the email would also be downloading malware into his or her computer network, according to the FireEye report. The company did not dispute NBC’s characterization of the report, but declined to comment.
