About the Spyderbat Nano Agent

1. How does Spyderbat collect data?

Spyderbat collects data by deploying a lightweight “Nano Agent” for Linux based systems.  The agent leverages eBPF (“extended Berkeley Packet Filter”) filters to build a continuous map of activity within and across systems.

2. Why do I need to install an agent?

Existing endpoint agents and system logs do not include the necessary information required by Spyderbat to build a complete, living map of causal activity within and across systems.  Spyderbat’s Nano Agent is optimized to collect this information so that analysts can see the complete causal attack picture across systems, users, and time.

3. What is the impact of the Spyderbat Nano Agent on the host system?

Spyderbat has observed minimal impact on system resources (CPU, memory) with early customers and design partners, and minimal network bandwidth impact due to heavy compression of data collected by the Nano Agent.


4. What systems does the Spyderbat Nano Agent currently support?

Spyderbat currently supports the following Linux systems

Linux Version
AlmaLinux 8.4
Amazon Linux 2
x86_64 / ARM64
Amazon Linux 2022
x86_64 / ARM64
Centos 7 (with El Repo LT)
Centos 8
Debian 10
Kali 2021.2
Redhat Enterprise Linux 7 (with El Repo)
Redhat Enterprise Linux 8
Sangoma 16 (with El Repo LT)
Ubuntu 18.04. LTS
Ubuntu 20 Desktop
Ubuntu 20.04 LTS
x86_64 / ARM64
Ubuntu 20.10

5. What are the Nano Agent’s network requirements?

Ensure that the systems running the Nano Agent have outbound access on port 443 to https://orc.spyderbat.com.

6. does the Nano Agent work with a Proxy?

If you have a proxy configured and you have Linux environment variables like:  




The installation script will automatically grab the environment variables from your terminal using the “-E” flag and pass those to the agent as required.

7. Is information sent securely from the Nano Agent?

Spyderbat securely encrypts information sent by the Nano Agent to the Spyderbat backend using TLS.


8. Does the Nano Agent support systems hosted in AWS?

The Nano Agent can be installed on any of the supported systems listed above as virtual or physical machines.  Additionally, the Nano Agent collects metadata from AWS instances such as Cloud Tags, Region, Zone etc. To collect this metadata, ensure your AWS instances have an appropriate IAM (read only) role assigned to them such as “AmazonEC2ReadOnlyAccess”, see https://docs.aws.amazon.com/AWSEC2/latest/WindowsGuide/security-iam-awsmanpol.html

9. How do I start and stop the Nano Agent from the Linux command line?

To start the Nano Agent:

                        sudo systemctl stop nano_agent.service

To stop the Nano Agent:

                     sudo systemctl start nano_agent.service
