Saferwall : An Open Source Malware Analysis Platform

Saferwall is an open source malware analysis platform. It aims for the following goals:

Provide a collaborative platform to share samples among malware researchers.
Acts as a system expert, to help researchers generates an automated malware analysis report.
Hunting platform to find new malwares.
Quality ensurance for signature before releasing.

Features

Static analysis:
- Crypto hashes, packer identification
- Strings extraction
- Portable Executable file parser
Multiple AV scanner which includes major antivirus vendors: Vendors status Vendors status Avast ✔️ FSecure ✔️ Avira ✔️ Kaspersky ✔️ Bitdefender ✔️ McAfee ✔️ ClamAV ✔️ Sophos ✔️ Comodo ✔️ Symantec ✔️ ESET ✔️ Windows Defender ✔️

Installation

Saferwall take advantage of kubernetes for its high availability, scalibility and the huge ecosystem behind it.

Everything runs inside Kubernetes. You can either deploy it in the cloud or have it self hosted.

To make it easy to get a production grade Kubernetes cluster up and running, we use kops. It automatically provisions a kubernetes cluster hosted on AWS, GCE, DigitalOcean or OpenStack and also on bare metal. For the time being, only AWS is officially supported. Refer to the following link for how to setup.

Built With

Golang mostly.
Backend: Echo
Frontend: VueJS + Bulma
Messaging: NSQ
Database: Couchbase
Logging: FileBeat + ElasticSearch + Kibanna
Minio: Object storage
Deployment: Helm + Kubernetes

Current Architecture / Workflow

Here is a basic workflow which happens during a file scan:

Frontend talks to the the backend via REST APIs.
Backend uploads samples to the object storage.
Backend pushes a message into the scanning queue.
Consumer fetches the file and copy it into to the nfs share avoiding to pull the sample on every container.
Consumer calls asynchronously scanning services (like AV scanners) via gRPC calls and waits for results.
