Government agencies in the US, UK, Canada, and Australia say that threat groups associated with Iran’s Islamic Revolutionary Guard Corps (IRGC) have been engaging in data encryption and extortion operations.
In a joint advisory published as an update to a November 2021 alert, agencies in the four countries say that Iranian state-sponsored threat actors affiliated with IRGC have been exploiting known vulnerabilities in Microsoft Exchange, Fortinet OS, and VMware Horizon Log4j for initial access.
Malicious attacks carried out by these advanced persistent threat (APT) actors, the authoring agencies say, involved encrypting files and exfiltrating data to engage in ‘double extortion’ activities.
“The IRGC-affiliated actors are actively targeting a broad range of entities, including entities across multiple U.S. critical infrastructure sectors as well as Australian, Canadian, and United Kingdom organizations. These actors often operate under the auspices of Najee Technology Hooshmand Fater LLC, based in Karaj, Iran, and Afkar System Yazd Company, based in Yazd, Iran,” the joint advisory reads.
Iranian government-sponsored APT actors were seen scanning for and exploiting vulnerabilities such as CVE-2018-13379, CVE-2019-5591, and CVE-2020-12812 (FortiOS); CVE-2021-34473, CVE-2021-34523, and CVE-2021-31207 (ProxyShell); and CVE-2021-44228, CVE-2021-45046, and canada australia iranian government agency ransomware attacks
