Tip checklist (authorized only)
- Confirm you may read membership on the host (lab VM / your sample / courseware).
- Prefer
groups/groups "$USER"short lists over dumping/etc/groupwholesale. - Record which username (if any) you queried — only accounts you may inspect.
- Quote short Evidence; redact if policy requires.
- If you need UID/GID numbers, cross-check id-user-tips.
- Optional: kernel/host → uname-tips / hostnamectl-tips.
- Optional: env context → env-vars-tips; keep a copy → tee-pipe-tips.
- Redact sensitive labels before sharing.
Allowed framing
- Classroom labs listing your own groups on a syllabus VM.
- Binding membership lists as Evidence.
- Documenting "groups not installed / no such user" as valid lab outcomes.
- Comparing groups ↔ id under one binder.
Scope we will not cover
- No crack/pirate/keygen via groups.
- No privilege-escalation / unauthorized-access / bypass PoCs.
- No credential-theft via group enumeration cookbooks.
- No intentional groups abuse against hosts you do not own.
Beginner path (authorized only)
- Obtain one syllabus-approved lab VM you control.
- Run
groups; quote the list (redact if needed). - Bind notes as Evidence.
- Optional: compare with id-user-tips.
- Stop at literacy — no escalation cookbooks.
Which to pick
- Prefer authorized, short, redacted Evidence.
- Use id / uname / hostnamectl peers when the syllabus asks.
- No exploit, crack, or unauthorized-access framing.

FAQ
What is a "groups tip" page in BinBench framing?
A checklist for listing authorized group membership on hosts you own — not a cookbook for enumerating other users without permission.
How does this relate to id-user-tips?
id-user-tips covers UID/GID Evidence. This page zooms on groups membership Evidence — it does not overwrite that page.
Can I groups-scan other users\' accounts I do not administer?
No. Authorization first. BinBench will not publish unauthorized-access recipes.
Does this teach exploit / privilege-escalation PoCs?
No. Mentions of exploit appear only as refusals. Authorized membership literacy only.
Does this teach credential theft via group dumps?
No. Redact group names if policy requires before sharing.
