Ivanti Connect Secure (ICS) devices are under attack! Two critical vulnerabilities are being exploited to deploy the notorious Mirai botnet.
Foreign nation-state cyber adversaries are tenacious. Their attacks are evolving to get around the industry’s most sophisticated defenses. Last year was exploitation of routers, and this year’s theme has been compromise of edge protection devices.
MITRE, a company that strives to maintain the highest cybersecurity possible, is not immune.
Despite our commitment to safeguarding our digital assets, we’ve experienced a breach that underscores the nature of modern threats. In this blog post, we provide an initial account of the incident, outlining the tactics, techniques, and procedures (TTPs) employed by the adversaries, as well as some of our ongoing incident response efforts and recommendations for future steps to fortify your defenses.

Based upon the authoring organizations’ observations during incident response activities and available industry reporting, as supplemented by CISA’s research findings, the authoring organizations recommend that the safest course of action for network defenders is to assume a sophisticated threat actor may deploy rootkit level persistence on a device that has been reset and lay dormant for an arbitrary amount of time. For example, as outlined in PRC State-Sponsored Actors Compromise and Maintain Persistent Access to U.S. Critical Infrastructure), sophisticated actors may remain silent on compromised networks for long periods. The authoring organizations strongly urge all organizations to consider the significant risk of adversary access to, and persistence on, Ivanti Connect Secure and Ivanti Policy Secure gateways when determining whether to continue operating these devices in an enterprise environment.
As part of our ongoing investigation into the vulnerabilities impacting Ivanti Connect Secure, Ivanti Policy Secure and ZTA gateways, we have discovered a new vulnerability. This vulnerability only affects a limited number of supported versions – Ivanti Connect Secure (version 9.1R14.4, 9.1R17.2, 9.1R18.3, 22.4R2.2 and 22.5R1.1), Ivanti Policy Secure version 22.5R1.1 and ZTA version 22.6R1.3.
A patch is available now for Ivanti Connect Secure (versions 9.1R14.5, 9.1R17.3, 9.1R18.4, 22.4R2.3, 22.5R1.2, 22.5R2.3 and 22.6R2.2), Ivanti Policy Secure (versions 9.1R17.3, 9.1R18.4 and 22.5R1.2) and ZTA gateways (versions 22.5R1.6, 22.6R1.5 and 22.6R1.7).
At Ivanti, our top priority is upholding our commitment to deliver and maintain secure products for our customers. Our team has been working around the clock to aggressively review all code and is singularly focused on bringing full resolution to the issues affecting Ivanti Connect Secure (formerly Pulse Connect Secure), Ivanti Policy Secure and ZTA gateways.
We have been following our product incident response process and rigorously assessing our products and code alongside world-class security experts and collaborating with the broader security ecosystem to share intelligence. We are committed to communicating findings openly with customers, consistent with our commitment to security and responsible disclosure.

Volexity regularly prioritizes memory forensics when responding to incidents. This strategy improves investigative capabilities in many ways across Windows, Linux, and macOS. This blog post highlights some specific ways memory forensics played a key role in determining how two zero-day vulnerabilities were being chained together to achieve unauthenticated remote code execution in Ivanti Connect Secure VPN devices.
