Docker Might Not Be Your Friend - Trojanizing Docker Images

Madrid, Spain

Docker can be your worst enemy if you don’t know what you’re doing.

What it’s about

With Roberto Muñoz we presented advanced techniques to trojanize Docker images and compromise systems through containers.

We talk about trojanizing images, backdoors in containers, attacks on registries (Docker Hub and private ones) and supply chain attacks through images. Also persistence and lateral movement via Docker.

Why it’s relevant

Everyone uses Docker and everyone trusts third-party images. Hardly anyone checks what’s inside them.

A trojanized image can compromise your whole infrastructure, and it’s easier than you think.

Impact

After this talk, many companies started scanning their Docker images and setting up private registries with security policies.

Dockerscan, my tool for Docker security analysis, was born from this research.
