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 system?

   Spyderbat has observed minimal impact on system resources (CPU, memory), and minimal network bandwidth impact due to heavy compression.

4. What systems are currently supported?

   Spyderbat currently supports the following Linux systems:

   AlmaLinux 8.4	x86_64
   AlmaLinux 9	x86_64
   Amazon Linux 2	x86_64 / ARM64
   Amazon Linux 2022	x86_64 / ARM64
   CentOS 7 up to 7.6 (with El Repo LT)	x86_64
   CentOS 7.6+ (with Kernel 3.10.0-957+)	x86_64
   CentOS 8	x86_64
   Debian 10	x86_64
   Kali 2021.2	x86_64
   RHEL 7.6+ (with Kernel 3.10.0-957+)	x86_64
   RHEL 8	x86_64
   RHEL 9	x86_64
   Rocky Linux 8	x86_64
   Rocky Linux 9	x86_64
   Sangoma 16 (with El Repo LT)	x86_64
   Ubuntu 18.04. LTS	x86_64
   Ubuntu 20 Desktop	x86_64
   Ubuntu 20.04 LTS	x86_64 / ARM64
   Ubuntu 20.10	x86_64

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 support network proxies?

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

       https_proxy=https://address:port
   
   

   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?

   Yes. 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 command line?

   To start the Nano Agent:

     sudo systemctl stop nano_agent.service
   
   

   To stop the Nano Agent:

     sudo systemctl start nano_agent.service
