Gholam Reza Jalali, the head of an Iranian military unit in charge of combatting sabotage, said that experts discovered the “espionage virus,” which he called “Stars.”

“The Stars virus has been presented to the laboratory but is still being investigated,” Jalali said in a report posted Monday on his organization’s website, paydarymelli.ir. “No definite and final conclusions have been reached.”

He did not say what equipment or facilities the virus targeted, or when experts first detected it.
