For legal, authorized and educational use only. Only analyze software you own or have written permission to examine.

Tip checklist (authorized only)
- Confirm you may scan the sample (lab VM / your build / courseware).
- Record sample path, hash, YARA version (
yara --version), and rule-set identity in Evidence. - Prefer a scoped rule file — not unbounded internet rule dumps you cannot attribute.
- Quote match rule names + short offset notes — not whole-file paste dumps.
- Note whether strings were ASCII / wide / hex so Evidence stays reproducible.
- Optional: escalate opaque blobs to strings-xor-tips or binwalk-carve-tips when carving is the next literacy step.
- Keep rule authorship questions on yara-rules-writing-tips — this page is scan Evidence.
- Redact secrets, cookies, and tokens before sharing.
Allowed framing
- Classroom scans of student-written helpers or courseware samples you control.
- Binding hashed sample + rule identity + short match note.
- Documenting "no match / rule compile error" as valid lab outcomes.
- Separating scan Evidence from rule-writing Evidence under one binder.
Scope we will not cover
- No crack/pirate/keygen of commercial apps via YARA matches.
- No exploit / evasion / AV-bypass PoCs mined from YARA.
- No credential-theft from matched files.
- No unauthorized scanning of third-party production hosts.
Beginner path (authorized only)
- Obtain one syllabus-approved sample you control.
- Run a scoped YARA rule set; save a short redacted match note.
- Hash sample + note YARA + rule-set identity; bind Evidence.
- Optional: open rule authorship questions on the rules-writing peer page.
- Stop at literacy — no exploit cookbooks.
Which to pick
- Prefer authorized, scoped-rule, redacted Evidence.
- Keep scan vs rule-writing lanes separate.
- No exploit, crack, or credential-theft framing.

FAQ
What is a "YARA scan tip" page in BinBench framing?
A checklist for scanning authorized samples with YARA (lab VMs, your own builds, courseware) — not a cookbook for attacking third-party hosts.
How does this differ from yara-getting-started-legal / yara-rules-writing-tips?
yara-getting-started-legal orients the project; yara-rules-writing-tips covers rule authorship. This page zooms on scan Evidence habits — it does not overwrite those pages.
Can I scan software I do not own to crack or bypass it?
No. Authorization first. BinBench will not publish crack/bypass recipes.
Does this teach exploit / evasion / bypass PoCs via YARA?
No. Mentions of exploit/bypass appear only as refusals. Authorized scan literacy only.
Does this teach credential theft from matched files?
No. Redact secrets, tokens, and PII in Evidence before sharing.
