One threat actor responsible for 83% of recent Ivanti RCE attacks

Single Threat Actor Dominates Exploitation of Critical Ivanti EPMM Vulnerabilities, Sparking Urgent Cybersecurity Warnings

In a striking development that has sent shockwaves through the cybersecurity community, recent threat intelligence analysis has uncovered that a single, highly sophisticated threat actor is responsible for the overwhelming majority of active exploitation attempts targeting two critical vulnerabilities in Ivanti Endpoint Manager Mobile (EPMM). These vulnerabilities, designated as CVE-2025-21962 and CVE-2025-24061, have been under active attack since their public disclosure, with the identified threat actor leveraging them in a coordinated and persistent campaign.

The vulnerabilities in question are particularly severe due to their potential impact on enterprise mobility management. Ivanti EPMM, formerly known as MobileIron Core, is a widely deployed solution used by organizations to manage and secure mobile devices across their networks. The flaws allow for remote code execution and unauthorized access, potentially giving attackers complete control over affected systems. The fact that a single entity is driving most of the exploitation activity suggests a highly targeted and resource-intensive operation, raising concerns about the actor’s motives and capabilities.

According to multiple cybersecurity firms tracking the incidents, the threat actor has demonstrated advanced tactics, including the use of custom malware, evasion techniques, and rapid adaptation to defensive measures. The exploitation appears to be part of a broader campaign aimed at infiltrating enterprise environments, exfiltrating sensitive data, and establishing long-term persistence. Analysts note that the actor’s focus on Ivanti EPMM is likely due to its widespread adoption in sectors such as healthcare, finance, and government, where the stakes for data breaches are exceptionally high.

Ivanti has responded swiftly, issuing patches and advisories to help organizations mitigate the risks. However, the speed and scale of the exploitation have outpaced many organizations’ ability to apply updates, leaving a significant number of systems exposed. Security experts are urging immediate action, emphasizing that the vulnerabilities are being weaponized in the wild and that delays in patching could result in catastrophic breaches.

The discovery of a single threat actor’s dominance in this campaign has also prompted deeper investigations into their identity and affiliations. While no definitive attribution has been made, some analysts speculate that the actor may be linked to a state-sponsored group or a highly organized cybercrime syndicate. The precision and scale of the attacks suggest access to substantial resources, including zero-day exploits, advanced infrastructure, and a deep understanding of enterprise environments.

This incident underscores the growing sophistication of cyber threats and the critical importance of proactive security measures. Organizations are being advised to prioritize patch management, conduct thorough vulnerability assessments, and enhance their threat detection capabilities. Additionally, the cybersecurity community is calling for greater collaboration and information sharing to counter such targeted campaigns effectively.

As the situation evolves, the focus remains on identifying and neutralizing the threat actor responsible for these exploits. The exploitation of Ivanti EPMM vulnerabilities serves as a stark reminder of the ever-present dangers in the digital landscape and the need for constant vigilance in safeguarding critical infrastructure.
