CISA Warns of ESURGE Malware Exploiting Ivanti RCE Vulnerability

The Cybersecurity and Infrastructure Security Agency (CISA) has issued a Malware Analysis Report (MAR-25993211-r1.v1) detailing the exploitation of a critical vulnerability in Ivanti Connect Secure devices (CVE-2025-0282). Additionally, CISA discovered a custom binary leveraging open-source tools like BusyBox and scripts such as extract_vmlinux.sh. These tools enable attackers to extract kernel images, analyze vulnerabilities, and execute payloads on compromised devices. CISA’s analysis revealed that RESURGE operates as a backdoor and rootkit, enabling attackers to establish Secure Shell (SSH) tunnels for command-and-control (C2) operations. This vulnerability allows attackers to gain unauthorized access and deploy sophisticated malware variants, including the newly identified RESURGE and SPAWNSLOTH. Cyber Security News is a Dedicated News Platform For Cyber News, Cyber Attack News, Hacking News & Vulnerability Analysis. These modifications allow attackers to maintain control over compromised systems while evading detection by security mechanisms. CISA strongly recommends that organizations using Ivanti Connect Secure devices take immediate action to mitigate this threat.
