About Curious Serpens.
When discussing suspected Middle Eastern hacker groups with destructive capabilities, many automatically think of the suspected Iranian group that previously used SHAMOON, aka Disttrack, to target organizations in the Persian Gulf. However, over the past few years, we have been tracking a separate, less widely known suspected Iranian group with potential destructive capabilities, whom we call APT33. Our analysis reveals that APT33 is a capable group that has carried out cyber espionage operations since at least 2013. We assess APT33 works at the behest of the Iranian government. APT33 has targeted organizations, spanning multiple industries, headquartered in the United States, Saudi Arabia and South Korea. APT33 has shown particular interest in organizations in the aviation sector involved in both military and commercial capacities, as well as organizations in the energy sector with ties to petrochemical production. APT 33 seems to be closely related to 'OilRig, APT 34, Helix Kitten, Chrysene' since at least 2017.
