OilRig

OilRig is a suspected Iranian threat group that has targeted Middle Eastern and international victims since at least 2014. The group has targeted a variety of sectors, including financial, government, energy, chemical, and telecommunications. It appears the group carries out supply chain attacks, leveraging the trust relationship between organizations to attack their primary targets. FireEye assesses that the group works on behalf of the Iranian government based on infrastructure details that contain references to Iran, use of Iranian infrastructure, and targeting that aligns with nation-state interests.(Citation: Palo Alto OilRig April 2017)(Citation: ClearSky OilRig Jan 2017)(Citation: Palo Alto OilRig May 2016)(Citation: Palo Alto OilRig Oct 2016)(Citation: Unit 42 Playbook Dec 2017)(Citation: FireEye APT34 Dec 2017)(Citation: Unit 42 QUADAGENT July 2018)
