According to the reported Channel 10 findings, hackers working for the Islamic Republic have breached computers belonging to more than 1,800 individuals.
Victim of the cyber attacks included hundreds of Israelis, primarily past and present senior officials.
The report noted that Israeli cyber security experts were able to identify one negligent hacker working for Iran, Yasser Balachi, who mistakenly revealed his e-mail address.
"Balachi said that he had not operated on his own initiative, rather for another cyber organization that commissioned the work," Channel 10 quoted Ron Davidson, the head of security services at Israeli cyber firm Check Point, as saying.
The report added that the cyber activities stopped a few months ago when the Iran realized that its operations had been exposed. Nevertheless, the hackers allegedly managed to extract information in one of the latest instances of ongoing global cyber warfare.
