Daily Bitwarden security briefing for your Slack channel

Every morning at 8am on a cron trigger, turn the last 24 hours of my Bitwarden organization activity into a short security briefing in Slack instead of a raw log dump.

Start with the Bitwarden List Events operation, querying from 24 hours before the run up to now. /events is the only paged endpoint in the Bitwarden public API and it pages with a continuationToken: keep requesting the next page, passing the token back each time, until the returned token is null. Stopping after the first page will silently read a fraction of the day and make a busy day look quiet.

Bitwarden identifies the actor on each event by member id, not by name. Call List Members once and build a lookup from member id to name and email so every finding in the briefing names a real person. If an actor id has no matching member, report it by id and note that the account appears to have been removed, since that is itself worth knowing.

Triage rather than forward. Bitwarden logs more than 50 event types and most of them are routine noise. Keep only what matters for security: failed login attempts, two factor authentication being switched off, member role escalations such as someone moving to Admin or Owner or being granted broader permissions, vault or organization exports, collection deletions, and organization policy changes. Stay quiet about routine item edits, item views, and ordinary successful logins that have nothing else attached to them.

Group the findings by person. For each person, give their name and email, then a short list of what they did and when. Then read across the whole day and describe patterns rather than listing lines: repeated failed logins followed by a successful one, two factor being disabled shortly before an export, a member escalating their own role, activity at an unusual hour for that person, or a burst of activity from one account that is well outside their normal pattern. Where something looks like an account takeover, say so plainly and name the first thing you would check.

Post the briefing to our security channel in Slack using the Slack Bot Send a Message operation. Keep it readable on a phone: a one-line headline verdict first, then the per-person findings, then the patterns worth investigating. When nothing noteworthy happened, say so explicitly with a short all clear rather than posting nothing, so an empty channel is never mistaken for a broken workflow.

Constraints to respect. Event logs require a Teams or Enterprise organization and the events request returns 403 on any other plan; if that happens, post a message to the channel explaining the plan requirement instead of failing silently. Client-side events flush to the Bitwarden server roughly every 60 seconds, so the final minute of the window may lag and will appear in the next day's briefing. A single events query can span at most 367 days, which is far wider than the 24 hour window this uses. The trigger is cron because the Bitwarden public API does not send outgoing webhooks.
