n0s1 - Secret Scanner

n0s1 (pronunciation) is a secret scanner for Slack, Jira, Confluence, Asana, Wrike, Linear, Zendesk, GitHub and GitLab. It scans all channels/tickets/items/issues within the target platform in search of any leaked secrets in the titles, bodies, messages and comments. It is open-source and it can be easily extended to support scanning many others ticketing and messaging platforms.

See USER_MANUAL.md to learn how to run a scan.

Secrets are defined by an adaptable configuration file: regex.yaml. The scanner loads the configuration and searches for sensitive information, which includes:

• Github Personal Access Tokens
• GitLab Personal Access Tokens
• AWS Access Tokens
• PKCS8 private keys
• RSA private keys
• SSH private keys
• npm access tokens

Currently supported target platforms:

• Local filesystem
• Slack
• Jira
• Confluence
• Asana
• Wrike
• Linear
• Zendesk
• GitHub
• GitLab
