The group identified as Emennet Pasargad has been using "false-flag campaigns under the guise of multiple personas," the bureau said.

The alleged Iranian cyberattack attack follows U.S. sanctions on Iran after Albania blamed it for hacking government systems.

The July attacks involved multiple groups responsible for different aspects of the operation against Albania, researchers said.

A group called "Homeland Justice," which the Albanian government said is a front for Iranian hackers, took responsibility for the cyberattacks.

The hackers linked to the Iranian government claimed to have attacked Albania for hosting an opposition group conference.
