CISA published a detailed Malware Analysis Report on two malware sets used to compromise Ivanti Endpoint Manager Mobile (EPMM) systems by exploiting CVE-2025-4427 and CVE-2025-4428. The report provides technical analysis, indicators of compromise, YARA and SIGMA detection rules, and actionable mitigation guidance. Organizations are urged to upgrade Ivanti EPMM to the latest version and treat mobile device management systems as high-value assets with enhanced monitoring and restrictions.

Ivanti Endpoint Manager Mobile (EPMM), formerly MobileIron Core, was found to contain multiple serious vulnerabilities that enabled unauthorized access, data exposure, and server compromise. The most prominent flaws, `CVE-2023-35078` and `CVE-2023-35081`, were patched by Ivanti in July 2023 after disclosure that attackers had exploited them against Norwegian organizations and a government agency. `CVE-2023-35078` is a critical authentication bypass affecting internet-facing API paths, while `CVE-2023-35081` is a directory traversal issue that can let an authenticated administrator write arbitrary files, including webshells; CISA added both to its Known Exploited Vulnerabilities catalog and urged immediate patching and compromise assessment. Subsequent reporting and vendor disclosures showed the exposure was broader than initially understood. Rapid7 highlighted `CVE-2023-35078` as a critical API access flaw, while Ivanti later disclosed `CVE-2023-35082`, saying additional exploitation paths meant all supported EPMM 11.10, 11.9, and 11.8 versions, along with older MobileIron Core releases, were affected depending on configuration. A joint CISA and NCSC-NO advisory said APT actors used the bugs from at least April through July 2023, leveraging compromised SOHO routers as proxies, deleting Apache logs with a malicious `mi.war` Tomcat application, conducting LDAP reconnaissance, and likely pivoting through Ivanti Sentry toward internal Exchange systems. More recent dCERT advisories indicate Ivanti EPMM continues to face multiple vulnerabilities, including issues that may allow code execution.

**Ivanti Endpoint Manager Mobile (EPMM)** is being actively exploited via two critical, unauthenticated remote code execution vulnerabilities, **CVE-2026-1281** and **CVE-2026-1340** (both reported as CVSS 9.8). Reporting describes attackers achieving full control of exposed EPMM/MDM infrastructure, including establishing reverse shells, deploying web shells, performing reconnaissance, and downloading additional malware; activity has been observed across multiple countries and sectors (including government, healthcare, manufacturing, and technology). **CISA added CVE-2026-1281 to the Known Exploited Vulnerabilities (KEV) Catalog**, and defenders are urged to apply Ivanti’s available fixes/updates per the vendor advisory. Telemetry and threat-intel observations indicate broad internet exposure and automation in exploitation. Unit 42 reported visibility into **4,400+** EPMM instances, and noted threat actors shifting from initial exploitation toward **dormant backdoors** intended to preserve access even after patching. GreyNoise data highlighted that a large share of observed exploitation traffic (reported as **83%**) originated from a single IP, `193.24.123.42`, associated with “bulletproof” hosting, with attackers rotating user-agent strings consistent with mass scanning/exploitation; the same infrastructure was also linked to attempts against other products (e.g., Oracle WebLogic, `telnetd`, and GLPI).

Ivanti disclosed two **critical, actively exploited** Ivanti Endpoint Manager Mobile (*EPMM*) vulnerabilities—**CVE-2026-1281** and **CVE-2026-1340**—described as unauthenticated code-injection issues enabling **remote code execution (RCE)** with a **CVSS 9.8** rating. Ivanti reported exploitation affecting a *very limited number* of customers at disclosure and warned that successful compromise of the EPMM appliance could expose sensitive data stored in the platform (e.g., admin/user details and managed-device metadata such as phone numbers, IPs, installed apps, and identifiers like IMEI/MAC), and potentially allow attackers to change device configurations via the API or web console, including authentication-related settings. Guidance from national cybersecurity authorities emphasized that EPMM’s role in mobile device management can make it a pivot point into internal environments, potentially enabling lateral movement if the appliance is compromised. Affected versions include EPMM **12.5.x, 12.6.x, and 12.7.x** (including **12.5.1.0** and **12.6.1.0** and earlier as specified), while Ivanti’s cloud offerings (e.g., *Ivanti Neurons for MDM*) and *Ivanti Endpoint Manager (EPM)* are not impacted. Ivanti provided interim mitigations/hotfixes (RPM-based) with the caveat that hotfixes may need reapplication after upgrades, and indicated a permanent fix is expected in **EPMM 12.8.0.0**; organizations were advised to patch immediately and review appliances for compromise indicators such as anomalous logs and unexpected admin/configuration changes.
