CyberSecurity Advisory

InfusionPoints is providing this cybersecurity advisory to our customers and contacts as a community service.

The Cybersecurity and Infrastructure Security Agency (CISA) within the US Department of Homeland Security (DHS) is sharing the following information with the cyber security community as a primer for assisting in the protection of our Nation’s critical infrastructure in light of the current tensions between the Islamic Republic of Iran and the United States and Iran’s historic use of cyber offensive activities to retaliate against perceived harm. Foremost, CISA recommends organizations take the following actions:

  1. Adopt a state of heightened awareness. This includes minimizing coverage gaps in personnel availability, more consistently consuming relevant threat intelligence, and making sure emergency call trees are up to date.
  2. Increase organizational vigilance. Ensure security personnel are monitoring key internal security capabilities and that they know how to identify anomalous behavior. Flag any known Iranian indicators of compromise and tactics, techniques, and procedures (TTPs) for immediate response.
  3. Confirm reporting processes. Ensure personnel know how and when to report an incident. The well-being of an organization’s workforce and cyber infrastructure depends on awareness of threat activity. Consider reporting incidents to CISA to help serve as part of CISA’s early warning system (see Contact Information section below).
  4. Exercise organizational incident response plans. Ensure personnel are familiar with the key steps they need to take during an incident. Do they have the accesses they need? Do they know the processes? Are your various data sources logging as expected? Ensure personnel are positioned to act in a calm and unified manner.

The U.S. intelligence community and various private sector threat intelligence organizations have identified the Islamic Revolutionary Guard Corps (IRGC) as a driving force behind Iranian state-sponsored cyberattacks–either through contractors in the Iranian private sector or by the IRGC itself.

Iranian Cyber Activity

According to open-source information, offensive cyber operations targeting a variety of industries and organizations—including financial services, energy, government facilities, chemical, healthcare, critical manufacturing, communications, and the defense industrial base—have been attributed, or allegedly attributed, to the Iranian government.

You should ensure that your firewalls, security information and event management (SIEM) systems, or other threat detection system / service is monitoring for any activity or suspicious behavior from the following IP addresses that have been linked to Iranian cyber activity. Note that InfusionPoints VNSOC360 customers are already being monitored at a heightened level of awareness, and our cybersecurity center is actively monitoring and tracking this threat.
