## What is Distroless
|
|
|
|
A distroless container is a type of container that **contains only the necessary dependencies to run a specific application**, without any additional software or tools that are not required. These containers are designed to be as **lightweight** and **secure** as possible, and they aim to **minimize the attack surface** by removing any unnecessary components.
|
|
|
|
Distroless containers are often used in **production environments where security and reliability are paramount**.
|
|
|
|
Some **examples** of **distroless containers** are:

## Weaponizing Distroless
|
|
|
|
The goal of weaponize a distroless container is to be able to **execute arbitrary binaries and payloads even with the limitations** implied by **distroless** (lack of common binaries in the system) and also protections commonly found in containers such as **read-only** or **no-execute** in `/dev/shm`.
|
|
|
|
### Through memory
|
|
|
|
Coming at some point of 2023...
|
|
|
|
### Via Existing binaries
|
|
|
|
#### openssl
|
|
|
|
****[**In this post,**](https://www.form3.tech/engineering/content/exploiting-distroless-images) it is explained that the binary **`openssl`** is frequently found in these containers, potentially because it's **needed** by the software that is going to be running inside the container.
