Patching as the primary defense. Microsoft recently released a single update for Azure Linux containing over 470 CVE fixes, reflecting the industry's struggle to keep pace with an AI-fueled surge in vulnerability discovery (The Register). Jeff Morhous argues that engineers must use AI-powered security audit skills to map codebases and hunt for vulnerabilities, as 3% of all critical software bugs in history were discovered in just the last month (Jeff Morhous from The AI-Augmented Engineer). This approach treats the rapid identification of flaws as a race that defenders can win through superior tooling and faster remediation cycles.
Isolation as the primary defense. Contrastingly, CERT-FR and other security researchers emphasize that patching is often insufficient, particularly for end-of-life hardware like refrigeration controllers where factory resets fail to remove persistent attacker access (Farida Khalaf from Lights On by Farida). Instead of relying on constant updates, they advocate for removing management interfaces from the public internet, implementing network segmentation, and using virtual patching to shield vulnerable systems (Farida Khalaf from Lights On by Farida). Linus Torvalds notes that eBPF subsystem fixes are finally arriving faster than new reports, yet most other kernel areas remain overwhelmed.
These positions diverge on whether security is a race to patch or a strategy of containment. While proponents of AI-driven auditing seek to fix the growing volume of bugs, the containment camp argues that the sheer velocity of discovery makes traditional patching unsustainable for many operational environments.
- Attackers used a leaked LiteLLM admin key to override branch protections and publish poisoned software packages to public repositories (TLDR Infosec).
- Kaspersky researchers found attackers using plaintext ESXi root credentials to encrypt entire virtual machine clusters without requiring a VM escape.

Identify and isolate all internet-facing management controllers in your network.
Use a device search engine like Shodan or Censys to scan your public IP ranges for exposed management web logins.
You need
- Access to your organization's public IP ranges
- A device search engine account
- Network access control configuration tools
Steps
- Search your public IP ranges in a device search engine to list all internet-accessible controllers.
- Identify which controllers are end-of-life by comparing models against vendor support lists.
- Remove management pages from the public internet immediately.
- Configure a secure VPN or protected network for any necessary remote access.
- Change default passwords on all remaining controllers and enable strict security modes.
