Bohrium is an Iranian state-sponsored threat actor primarily focused on cyber espionage, with operations documented since at least 2017. The group is known for collecting sensitive information from high-value targets. Bohrium is closely associated with Iran's Islamic Revolutionary Guard Corps (IRGC) and is also tracked under several other names, including IMPERIAL KITTEN and Smoke Sandstorm, which sometimes creates confusion with other unrelated threat groups. A defining characteristic of Bohrium's operations is its use of social engineering, particularly by creating fake social media profiles posing as recruiters to initiate targeted spear-phishing campaigns. The group consistently seeks to obtain intelligence to further Iranian geopolitical objectives.
