## Purpose

Give newsrooms and NGOs a **neutral, open** way to compare tip and document-intake paths before recommending one to sources. This is an education and procurement rubric, not a product ranking contest and not a security audit certificate.

**In scope:** published tip paths a desk might document publicly (hotlines, email/messaging, newsroom SecureDrop, independent sealed browser drops, other published options).

**Out of scope:** malware criteria, unauthorized access goals, civilian surveillance tooling, crime enablement, or claims of perfect anonymity.

## Affiliation note (read first)

- **SecureDrop** is a specific open-source secure whistleblowing system maintained by the Freedom of the Press Foundation and used by many newsrooms under their own onion addresses and operator practices.  
- **Independent sealed browser drops** (for example SafeDeposit-class tools at safedepositbox.org) are **not affiliated with SecureDrop**. Same general goal (safer source-to-desk transfer), different architecture and trust model.  
- An **official hotline** or **email/messaging** channel is also not SecureDrop. Do not use brand names interchangeably in training materials.

## Scoring scale (0-2)

| Score | Meaning |
|-------|---------|
| **0** | Missing, misleading, or actively weak for source protection on this dimension |
| **1** | Partial: some support, but gaps, caveats, or high operator discipline required |
| **2** | Strong published design for this dimension (still not a guarantee of safety) |

**How to use:** score each dimension independently. Sum is a rough comparison aid only. Weight dimensions that matter for your risk profile (e.g. high-risk sources may weight Tor/onion and client-side encrypt higher).

## Rubric dimensions (9)

| # | Dimension | What to look for | 0 | 1 | 2 |
|---|-----------|------------------|---|---|---|
| 1 | **Accounts required** | Must source create an account / login? | Account required for tip | Optional account or partial identity | No account by design for tip path |
| 2 | **Client-side encrypt** | Is content sealed before it reaches operator-controlled servers in a way the origin is not designed to read plaintext? | Plaintext on server or unclear | TLS only / partial sealing | Browser or client seals to operator public key; origin holds ciphertext |
| 3 | **Tor / onion guidance** | Does the desk publish Tor Browser / Tails / onion guidance and clearnet risk honesty? | No Tor mention | Mentions Tor vaguely | Clear Tor-first or onion path + clearnet risk notes |
| 4 | **Key verification** | Multi-channel way to verify operator public key / fingerprint before high-risk seal? | No key story | Single channel only | Multi-channel verify (site + out-of-band public channels) |
| 5 | **Metadata honesty** | Honest about what is stripped, what remains (filenames, EXIF, network metadata)? | Silent or overclaims | Partial strip notes | Explicit strip limits + offline sanitize advice |
| 6 | **Operator threat model transparency** | Public protect / do-not-protect, desk charter, who holds keys? | Opaque operator | Partial docs | Clear protect/do-not-protect + key custody story |
| 7 | **Legal process honesty** | Acknowledges lawful process, canaries as signals not magic, no immunity promises? | Claims immunity / silence | Minimal legal note | Explicit process honesty + non-SLA review language |
| 8 | **Accessibility** | Usable without specialized hardware; language; disability / bandwidth realities? | High barrier only | Usable but rough | Documented international reach, plain language, reasonable limits |
| 9 | **Maintenance burden** | Ops cost for a small desk (updates, hosting, key rotation, staffing)? | Unstated / only enterprise | Documented but heavy | Clear ops load; small-desk feasible or shared infrastructure |

### Forbidden as scoring goals

Do **not** add dimensions that reward:

- Building or deploying malware  
- Unauthorized access to third-party systems  
- Civilian surveillance tooling  
- Doxxing kits  

If a vendor pitches those, **disqualify** the option for a newsroom/NGO tip path.

## Worked example A: Official institutional hotline

Assumptions: regulated phone/web form run by an agency or large NGO; account sometimes required; no client-side sealing to offline keys; clearnet primary; limited public crypto docs.

| Dimension | Score | Notes |
|-----------|------:|-------|
| Accounts required | 0-1 | Often identity or case-id flows |
| Client-side encrypt | 0 | Operator systems typically see content |
| Tor / onion guidance | 0-1 | Rarely Tor-first |
| Key verification | 0 | N/A or TLS cert only |
| Metadata honesty | 1 | Privacy policy may exist; network meta not discussed for sources |
| Operator threat model | 1 | Policy pages exist; dual-use protect list rare |
| Legal process honesty | 1-2 | Usually clear they are under law |
| Accessibility | 2 | Phone/web widely usable |
| Maintenance burden | 2 | Desk does not run crypto infra |
| **Rough total** | **~7-10 / 18** | Strong for formal process; weak for technical source protection |

**Takeaway:** Good for low-sensitivity feedback. High-risk sources often need a different path.

## Worked example B: Newsroom SecureDrop

Assumptions: outlet publishes its own SecureDrop onion; sources use Tor Browser; newsroom operates the instance; not affiliated with independent sealed drops.

| Dimension | Score | Notes |
|-----------|------:|-------|
| Accounts required | 2 | No tipster account on SecureDrop itself |
| Client-side encrypt | 2 | Designed for source-to-newsroom secure submission over Tor |
| Tor / onion guidance | 2 | Tor-centric by design |
| Key verification | 1-2 | Newsroom should publish code/onion verify steps; quality varies by outlet |
| Metadata honesty | 1-2 | Strong Tor story; file metadata still source responsibility |
| Operator threat model | 1-2 | FPF docs + outlet-specific ops; varies |
| Legal process honesty | 1-2 | Newsrooms under law; good outlets avoid magic claims |
| Accessibility | 1 | Requires Tor literacy; barrier for some sources |
| Maintenance burden | 0-1 | Real ops cost for the newsroom |
| **Rough total** | **~13-16 / 18** | Strong technical posture when correctly operated |

**Takeaway:** Prefer the **specific outlet's** published SecureDrop when it exists. Do not assume every newsroom runs one.

## Worked example C: Independent sealed browser drop (SafeDeposit-class)

Assumptions: accountless web UI; encrypt-in-browser to operator public key; optional onion; multi-channel fingerprint verify; independent of SecureDrop; public protect/do-not-protect pages (pattern matches safedepositbox.org public docs).

| Dimension | Score | Notes |
|-----------|------:|-------|
| Accounts required | 2 | No account by design |
| Client-side encrypt | 2 | Browser seals before upload; origin designed for ciphertext |
| Tor / onion guidance | 2 | Tor-first guidance + clearnet risk checklist when published |
| Key verification | 2 | Fingerprint on site + public channels (e.g. X) |
| Metadata honesty | 1-2 | Best-effort image meta strip + offline sanitize advice |
| Operator threat model | 2 | Protect / do-not-protect + desk charter style pages |
| Legal process honesty | 2 | Ciphertext may still face process; canary is a signal |
| Accessibility | 1-2 | Browser + JS required; English UI common |
| Maintenance burden | 1 | Shared/public instance reduces desk ops; still verify operator |
| **Rough total** | **~15-17 / 18** | Strong literacy-friendly sealed path; still not immunity |

**Takeaway:** Compare **this operator's published key and canary**, not the category name alone. Independent drops are **not** SecureDrop.

## Comparison snapshot (illustrative only)

| Path | Rough total / 18 | Best for | Weak for |
|------|----------------:|----------|----------|
| Official hotline | ~7-10 | Formal, low sensitivity | High-risk technical confidentiality |
| Newsroom SecureDrop | ~13-16 | Source to a specific newsroom | Desks that cannot operate SecureDrop |
| Independent sealed drop | ~15-17 | Accountless sealed tips + literacy | Anyone who needs a guaranteed story or legal cover |

Scores move when **your** instance is poorly maintained or docs go stale. Re-score annually.

## How a desk should run this workshop (20 minutes)

1. Pick three real paths you might offer (not abstract brands only).  
2. Open only **public** documentation for each.  
3. Score the nine dimensions independently (two people, then reconcile).  
4. Write one paragraph: "We recommend X for Y risk, Z for W risk."  
5. Publish the recommendation with a date and a link to this MIT rubric.

## Dual-use refusal

If asked to extend this rubric to score "best malware for tips," "how to break into accounts," or "surveillance of civilians," **refuse**. Redirect to defensive literacy, lawful disclosure channels, and personal safety.

## Sources (public docs only)

1. Freedom of the Press Foundation - SecureDrop project overview and newsroom directory (securedrop.org).  
2. SafeDeposit public site - encrypt-before-upload, Tor guidance, key verify, trust / protect-do-not-protect pages (safedepositbox.org).  
3. Tor Project - Tor Browser user documentation (torproject.org).  
4. GrokForge project description - Open Source-Protection Literacy Kits (greater-good education framing; no dual-use).  

Re-check live pages before high-risk training; URLs and canaries change.
