A collection to defend Vaultwarden instance against common attacks :

• Vaultwarden parser
• Vaultwarden bruteforce & enumeration detection

Example acquisition for this collection :

If using LOG_FILE environment variable:

1---
2filenames:
3 - /var/log/vaultwarden.log
4labels:
5  type: Vaultwarden

If running via systemd:

1---
2source: journalctl
3journalctl_filter:
4  - "SYSLOG_IDENTIFER=Vaultwarden"
5labels:
6  type: Vaultwarden

In the default configuration of vaultwarden logs, the timestamp uses system local time. This means that detection may not work as expected as CrowdSec uses UTC time. To fix this, you can configure vaultwarden to log the offset from UTC time. To do this, head over to Vaultwarden Admin Panel -> Advanced Settings -> Log timestamp format and change format to %Y-%m-%d %H:%M:%S.%3f%z.
