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.
The MITRE Corporation says a state-backed hacking group breached its systems in January 2024 by chaining two Ivanti VPN zero-days.
Ivanti has released security updates to fix 27 vulnerabilities in its Avalanche mobile device management (MDM) solution, two of them critical heap overflows that can be exploited for remote command execution.
The Shadowserver Foundation identifies thousands of Ivanti VPN instances likely impacted by a recent remote code execution flaw.
IT security software company Ivanti has released patches to fix multiple security vulnerabilities impacting its Connect Secure and Policy Secure gateways.
Ivanti warned customers to immediately patch a critical severity Standalone Sentry vulnerability reported by NATO Cyber Security Centre researchers.
Hackers breached the systems of the Cybersecurity and Infrastructure Security Agency (CISA) in February through vulnerabilities in Ivanti products, officials said.
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) revealed today that attackers who hack Ivanti VPN appliances using one of multiple actively exploited vulnerabilities may be able to maintain root persistence even after performing factory resets.
Dans la plupart des cas, les attaquants n’ont pas tenté d’aller plus loin, sauf quelques exceptions. Il s’agissait vraisemblablement pour les attaquants de mettre d’abord un premier pied chez leur cible.
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.
In 2021, Ivanti patched a vulnerability that they called “code injection”. Rumors say it was a backdoor in an open source project. Let’s find out what actually happened!
Hackers are exploiting a server-side request forgery (SSRF) vulnerability in Ivanti Connect Secure, Policy Secure, and ZTA gateways to deploy the new DSLog backdoor on vulnerable devices.
Today, Ivanti warned of a new authentication bypass vulnerability impacting Connect Secure, Policy Secure, and ZTA gateways, urging admins to secure their appliances immediately.
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.
On January 15, 2024, Volexity detailed widespread exploitation of Ivanti Connect Secure VPN vulnerabilities CVE-2024-21887 and CVE-2023-46805. In that blog post, Volexity detailed broader scanning and exploitation by threat actors using still non-public exploits to compromise numerous devices. Subsequently, Volexity has observed an increase in attacks from various threat actors against Ivanti Connect Secure VPN appliances beginning the same day.
Starting January 10, 2024, multiple parties (Ivanti, Volexity, and Mandiant) disclosed the existence of a zero-day exploit chain affecting Ivanti Connect Secur…
On January 10, 2024, Volexity publicly shared details of targeted attacks by UTA00178 exploiting two zero-day vulnerabilities (CVE-2024-21887 and CVE-2023-46805) in Ivanti Connect Secure (ICS) VPN appliances. On the same day, Ivanti published a mitigation that could be applied to ICS VPN appliances to prevent exploitation of these vulnerabilities. Since publication of these details, Volexity has continued to monitor its existing customers for exploitation. Volexity has also been contacted by multiple organizations that saw signs of compromise by way of mismatched file detections. Volexity has been actively working multiple new cases of organizations with compromised ICS VPN appliances.
