Hackers have taken advantage of a recently patched vulnerability in Cisco's networking devices, exploiting a flaw known as CVE-2025-20352. This issue allows remote code execution, which means attackers can run malicious code on the devices without needing physical access. In this case, they deployed a Linux rootkit to gain long-term access to older, unprotected switches.

If you’re managing these devices, you need to be on high alert. The attackers are using this flaw to infiltrate networks, raising serious security concerns. Cisco has rolled out patches, so it's crucial to update your systems if you haven't already. Ignoring this could leave your network vulnerable to further attacks. Stay vigilant and make sure your defenses are up to date.
