  • Static Analysis of Linux Malware Captured by a Cowrie Honeypot

    This story was originally published on HackerNoon at: https://hackernoon.com/static-analysis-of-linux-malware-captured-by-a-cowrie-honeypot.


    A defensive, static deep dive into the Linux malware a honeypot captured after weak logins: fake daemons, persistent backdoors, relay abuse, and detections.

    When a bot thinks it has logged into a small energy device, it installs commodity Linux malware. This is a static, defensive breakdown of what a honeypot captured after weak SSH and Telnet logins: fake-daemon binaries that masquerade as sshd and xinetd, a statically linked bot, a backdoor with three independent persistence mechanisms, and a self-deleting campaign visible only through commands. The payloads are ordinary, but the chain is the lesson: weak login, host fingerprint, payload staging, persistence, and reach-out. Default-deny egress breaks the last step.

    Policy-driven security in Kubernetes AI platforms enables organizations to enforce governance automatically across AI workloads, including LLMs, RAG systems, and vector databases. By using RBAC, network policies, admission controllers, Kyverno, and OPA Gatekeeper, teams can implement policy-as-code to ensure consistent security, prevent misconfigurations, and maintain continuous compliance. Integrating these controls into CI/CD pipelines helps shift security left and reduces risks in fast-moving AI environments.

  • Every AI Agent Is a Non-Human Identity That Needs Governance

    This story was originally published on HackerNoon at: https://hackernoon.com/every-ai-agent-is-a-non-human-identity-that-needs-governance.


    AI agents create new security identities. Learn why identity lifecycle management, not prompt engineering, is the foundation of secure agentic AI.

    The article argues that the biggest security challenge in agentic AI isn't prompt injection but identity management. By treating AI agents as first-class security principals with scoped, short-lived credentials, proper lifecycle management, and auditable delegation, organizations can apply proven identity engineering practices to reduce AI risk.

  • How to Secure a Self-Hosted CI/CD Runner on a VPS Without Turning It Into a Backdoor

    A self-hosted CI/CD runner on a VPS should be treated like part of your production delivery chain, not just a build machine. Before using it, harden the server, disable risky SSH access, limit inbound traffic, isolate runners by trust level, keep secrets out of the VPS, avoid giving Docker jobs excessive privileges, monitor disk/CPU/memory, plan Docker cleanup, and document recovery steps. The core rule is simple: never let untrusted code run on a runner that can access production secrets or infrastructure.
