European authorities have taken necessary measures to take down a cyber espionage campaign by the Iranian group Rocket Kitten.

The group was spotted more than a year ago, and authorities have been trying to get them ever since.

Rocket Kitten has targeted high-profile political and military figures globally including Saudi royal family, Israeli nuclear scientists, NATO officials, Iranian dissidents along with Islamic and anti-Islamic preachers and groups.

According to researchers from Check Point Software the number of targets went up to 1600 since 2014.

The researchers traced the attackers and found that "Wool3n.H4T," was one of the prominent figures behind this campaign and the group reportedly tried to get sensitive information from their targets.

According to reports, the company has already informed national computer security response teams in Britain, Germany and the Netherlands about the issue, who have in- turn alerted the Iranian police about the incident.

Check Point research group manager Shahar Tal said: "This research provides a rare look at the nature and global targets of a global cyber espionage group.

"While Check Point customers are protected against all known variants of these threats by Rocket Kitten, it is our hope fellow security vendors and malware research professionals take the proper precautions and deploy relevant protections."

Iran has been subjected to cyber attack and computer virus campaigns including Stuxnet which destroyed some of the Iranian nuclear production facilities.
