What's Happening?
Trend Micro reports that older Cisco devices, unpatched against a recent zero-day vulnerability, have been infected with a rootkit in a new campaign dubbed Operation ZeroDisco. The vulnerability, CVE-2025-20352, allows attackers to deploy rootkits on devices such
as Cisco 9400, 9300, and legacy 3750G series. The campaign exploits SNMP and Telnet flaws to achieve remote code execution and lateral movement across networks.
Why It's Important?
The exploitation of vulnerabilities in Cisco routers highlights the critical need for timely patching and robust security measures in network infrastructure. As cyber threats evolve, organizations must prioritize cybersecurity to protect sensitive data and maintain operational integrity. The deployment of rootkits poses significant risks, including data breaches and service disruptions, emphasizing the importance of proactive threat detection and response.
