Background for this topic.
Cisco produces networking devices and software that manage data flow in enterprise and service provider networks, including routers, switches, and firewalls. These components are often central points controlling network traffic and access, making their integrity critical for secure communications and network stability.
Security risks with Cisco equipment commonly arise from firmware vulnerabilities, exposed management interfaces, and configuration errors that attackers can exploit to gain unauthorized access or disrupt services. Timely application of security patches and strict access controls on device management interfaces are essential to reduce exposure. Monitoring network devices for unusual activity also helps detect potential compromises early in environments relying on Cisco infrastructure.

Broken vdaemon Peering Authentication Enables Unauthenticated Admin AccessA maximum-severity vulnerability in Cisco Catalyst SD-WAN Controller is being actively exploited, giving attackers administrative privileges without authentication. The authentication bypass vulnerability stems from a broken peering authentication mechanism.
Chuck Robbins Warns Customers Face Growing Exposure From Equipment Past SupportCisco is embedding Anthropic's Claude Mythos Preview into internal security operations to test code, accelerate patching and push infrastructure upgrades, even as it lays off 4,000 employees to redirect spending toward AI, silicon, optics and security.
'Firestarter' Backdoor Can Survive Reboots, Upgrades and Standard FixesThe Cybersecurity and Infrastructure Security Agency issued an emergency directive warning a newly-discovered Cisco backdoor can survive routine remediation processes, forcing agencies to investigate edge devices that anchor federal firewall and VPN security.
Deal Would Help Cisco Expand Footprint Beyond Authentication, ITDR and ISPMCisco's cyber M&A dry spell could soon come to an end, with the company reportedly in talks to acquire New York-based non-human identity startup Astrix Security for between $250 million and $350 million. That would represent at least a 25% premium to the startup’s last valuation of around $200 million.
Cisco's Jeetu Patel on How Machine-Speed Threats Drive Need for AI-Led SecurityCisco's Jeetu Patel explains how AI models are compressing exploit timelines to minutes, forcing a shift to machine-speed defense, real-time enforcement and deeper ecosystem collaboration to secure critical infrastructure and stay ahead of adversaries.
Why Remote Access to Industrial Operations Is the Biggest Unmanaged RiskRemote access has become one of the largest unmanaged attack surfaces in industrial operations. Legacy VPNs and jump servers expose OT environments to serious risk. Learn how Cisco Cyber Vision's Secure Equipment Access can secure vendor and engineer access while protecting critical infrastructure.

Cisco's Jeetu Patel: Everyone Will Be a 'Manager of Agents'Coding agents that once struggled below the surface level of basic web development can now refactor decades-old enterprise code at a speed and scale far beyond traditional teams, says Cisco's Jeetu Patel. He explains how AI-built software and machine-scale defense redefine competitive advantage.
AWS Researchers Find an Interlock Server Laden With ToolsRansomware hackers exploited a flaw with a maximum vulnerability score in Cisco firewall management software weeks before the networking giant disclosed the vulnerability in early March. The group has focused extensively on critical infrastructure sectors in North America and Europe.
Three-Year Old Zero-Day Under Mass AttackA flaw in Cisco Software-defined network management software has become a hacker free-for-all, warn cybersecurity experts. The flaw allows an unauthenticated remote attacker to bypass authentication and obtain administrative privileges on the affected system.
Researchers Tie UAT-9244 Intrusion to Famous Sparrow and Tropic TrooperA China-linked cyberespionage group has been targeting telecommunications providers in South America since 2024 using a set of newly discovered malware tools designed to maintain persistent access to critical communications infrastructure, Cisco Talos researchers found.

A LexisNexis breach. Woman sentenced for trafficking Microsoft licenses. Silver Dragon targeted governments. Broadcom patch. A Mississippi medical clinic resumed operations.
Emergency CISA Directive Lands as DHS Shutdown Strains Cyber OperationsThe Cybersecurity and Infrastructure Security Agency issued a directive Wednesday ordering civilian agencies to secure and hunt for compromise in vulnerable Cisco SD-WAN systems after officials observed active exploitation - while warning that shutdown-related disruptions heighten operational risk.
Cisco: One Prompt May Not Break Most AI Models, But a Conversation WillCisco tested eight major open-weight artificial intelligence models and found multi-turn jailbreak attacks succeeded nearly 93% of the time, exposing a blind spot in how enterprises assess and deploy large language models safety.
Cisco Research Shows How AI Is Reshaping Data Privacy and GovernanceEnterprise data privacy and governance are undergoing fundamental shifts as the promised speed and efficiency of artificial intelligence come crashing into the realities of data risk and regulatory uncertainty.
Vendor Ships Emergency Fixes, Warning Flaw Facilitates Full System CompromiseAttackers are targeting a zero-day vulnerability in Cisco's Unified Communications and Webex products that facilitates remote code execution and root-level access to the underlying operating system, risking full system compromise. Cisco has released patches, warning that no workarounds exist.
Cisco Fixes ISE Bug; HPE OneView Under Fire; Exploit Code Drops for n8n FlawThe new year is off to a fresh start on the vulnerability and exploit alert front: Cisco has patched a critical Identity Services Engine; cybersecurity officials warn that an HPE OneView vulnerability is being actively exploited; and proof-of-concept exploits drop for n8n automation software.
