A hacking group has revealed the identities of several hackers working for the cyber division of Iran’s Revolutionary Guard (IRGC). 

According to information obtained by Iran International July 16, these hackers – or the so-called Iranian Cyber Army -- work for Naji Technology and Afkar System companies, which are affiliated with the IRGC. 

In their report, the hacktivist group, called ‘Lab-Doukhtegan’ or ‘Sealed Lips’, said these IRGC hackers “repeatedly attacked targets in the US and Europe with the aim of extortion," making use of "the security loopholes discovered in European and American organizations.”

Early in June, the ranking member of the US Senate Foreign Relations Committee condemned the cyberattack by Iran-backed hackers on Boston Children’s Hospital last summer. 

Describing the attempted attack as “deeply disturbing,” Idaho’s Republican Senator Jim Risch said that “it’s typical of a regime that’s synonymous with global terrorism.”

Later in June, Israeli Defense Minister Benny Gantz said an IRGC cyber unit called “Shahid Kaveh” conducted research to damage ships, gas stations and industrial plants in several countries including Britain, the US, France and Israel.

Gantz hinted that Israel -- which is widely believed to have waged cyber war against Iran's nuclear facilities and other infrastructure -- may retaliate physically against enemy hackers.

Iran has been repeatedly accused of cyber-attacks against the West, Israel and rival Arab countries in the Middle East.
