Tip checklist (authorized only)

  1. Confirm you may type the file (lab VM / your build / courseware).
  2. Record path, hash, file version/flags (--mime, -b), and output in Evidence.
  3. Type only a short set of samples — not unbounded whole-tree crawls.
  4. Quote MIME + charset lines; redact paths that hold secrets.
  5. Note magic database version when available so Evidence stays reproducible.
  6. Optional: bind metadata with stat-file-tips.
  7. Optional: inspect a short hex window with hexdump-view-tips.
  8. Redact secrets, cookies, tokens, and home-directory paths before sharing.

Allowed framing

  • Classroom typing of student-written helpers you control.
  • Binding hashed path + MIME line + flag note.
  • Documenting "cannot open / data" as valid lab outcomes.
  • Comparing MIME ↔ magic cousin under one binder.

Scope we will not cover

  • No crack/pirate/keygen of commercial apps via type labels.
  • No exploit / polyglot / ASLR-bypass PoCs mined from file(1).
  • No credential-theft from typed content.
  • No unauthorized typing of third-party production hosts.

Beginner path (authorized only)

  1. Obtain one syllabus-approved file you control.
  2. Run file --mime (or equivalent) and record the line.
  3. Hash file + note tool/flags; bind Evidence.
  4. Optional: add stat fields for a second Evidence lane.
  5. Stop at literacy — no exploit cookbooks.
Which to pick
  • Prefer authorized, sample-scoped, redacted Evidence.
  • Use magic / stat / hex peers when the syllabus asks.
  • No exploit, crack, or credential-theft framing.

FAQ

What is a "file MIME tip" page in BinBench framing?

A checklist for typing authorized files you own with file(1) (lab VMs, your builds, courseware) — not a cookbook for attacking third-party apps.

How does this differ from file-magic-tips?

file-magic-tips orients magic habits. This page zooms on MIME/type Evidence binding — it does not overwrite that page.

Can I type software I do not own to crack or bypass it?

No. Authorization first. BinBench will not publish crack/bypass recipes.

Does this teach exploit / polyglot / bypass PoCs via file(1)?

No. Mentions of exploit/bypass appear only as refusals. Authorized type literacy only.

Does this teach credential theft from typed files?

No. Redact secrets, tokens, and PII in Evidence before sharing.
