These rules are provided freely to the community without warranty.
|
||||
|
||||
In this GitHub repository you will find rules in multiple languages:
|
||||
- Snort
|
||||
- Yara
|
||||
- IOC
|
||||
- ClamAV
|
||||
|
||||
The rules are categorized and labeled into two release states:
|
||||
- Production: rules that are expected to perform with minimal tuning.
|
||||
- Supplemental: rules that are known to require further environment-specific tuning and tweaking to perform, and are often used for hunting workflows.
|
||||
|
||||
Please check back to this GitHub for updates to these rules.
|
||||
|
||||
FireEye customers can refer to the FireEye Community (community.fireeye.com) for information on how FireEye products detect these threats.
|
||||
|
||||
The entire risk as to quality and performance of these rules is with the users.

<short_description>SUNBURST SUSPICIOUS CHILD PROCESSES (METHODOLOGY)</short_description>
|
||||
<description>This rule identifies suspicious child processes of SolarWinds.Orion.Core.BusinessLayer.dll that may be evidence of the SUNBURST backdoor. The behavior of SolarWinds.Orion.Core.BusinessLayer.dll is dependent on per-enterprise configuration, so additional tuning may be required to exclude legitimate activity in a given environment. SUNBURST is a backdoor that has the ability to spawn and kill processes, write and delete files, set and create registry keys, gather system information, and disable a set of forensic analysis tools and services.

<short_description>SUNBURST SUSPICIOUS FILEWRITES (METHODOLOGY)</short_description>
|
||||
<description>This rule identifies writes of specific file types associated with activity related to the SUNBURST backdoored version of the SolarWinds.Orion.Core.BusinessLayer.dll process. This rule may generate false positives depending on the configuration of SolarWinds in a given environment, and may require tuning to exclude legitimate activity. SUNBURST is a backdoor that has the ability to spawn and kill processes, write and delete files, set and create registry keys, gather system information, and disable a set of forensic analysis tools and services. This is associated to MITRE ATT&CK (r) Tactic: Initial Access and Technique: T1195.002</description>

<short_description>SUNBURST SUSPICIOUS URL HOSTNAME (METHODOLOGY)</short_description>
|

<description>This rule identifies URL requests mimicking SolarWinds network traffic, to non-SolarWinds domains. This rule will only match on instances where communication does not occur over SSL/TLS. These requests may be evidence of the SUNBURST backdoor. SUNBURST is a backdoor that has the ability to spawn and kill processes, write and delete files, set and create registry keys, gather system information, and disable a set of forensic analysis tools and services.
