Attack Case Library (Public, Non-Weaponized)

Purpose:

Publish concrete adversarial test cases that the public can critique and improve.
Make it easy to verify that defenses work by providing repeatable negative tests and expected outcomes.
Provide patch patterns and regression test guidance so fixes stick.

Important:

Do not use this document to attack systems you do not own or explicitly control.
This library is written to avoid step-by-step exploit instructions that would be directly weaponizable against real systems. It focuses on verifying invariants and detecting failures in controlled environments.

Each case should be written as:

ID
Target invariant / security property
Preconditions
Test (adversarial attempt)
Expected defense behavior
Evidence to capture
Common root causes
Patch patterns
Regression tests to add

Case Set A: Replay and Idempotency (Gateway)

A01: Challenge Replay (Single-Use)

Target: anti-replay via challenge lifecycle
Preconditions: a valid challenge has been issued
Test: attempt to use the same challenge for two casts in a controlled environment
Expected: the second cast is rejected deterministically (no state corruption)
Evidence: gateway logs, error code, idempotency records, receipt absence
Root causes: challenges not marked used atomically; caching mistakes; multi-node races
Patch patterns: atomic challenge consumption; bind challenge to cast inputs; consistent TTL checks
Regression: integration test that replays a challenge and asserts deterministic rejection

POC validation (safe, local-only):

Open /votechain/poc/vote
Generate credential, request a challenge
Cast once (should succeed)
Cast again without requesting a new challenge (should fail)

A02: Challenge Expiry Enforcement

Target: freshness windows and expiry handling
Preconditions: issue a challenge with a short TTL (or wait until it expires)
Test: attempt to cast after expiry
Expected: rejection with a retryable “expired” style error (and guidance to request a new challenge)
Evidence: server-side timestamps, rejection code, client-facing message
Root causes: clock skew handling; parsing timestamps incorrectly; inconsistent TTL across nodes
Patch patterns: use a consistent time source; define skew tolerance; always compare in UTC
Regression: test vector with a challenge expires_at in the past must fail

A03: Idempotency-Key Body Mismatch

Target: idempotency semantics prevent replay + confusion
Preconditions: a valid cast request exists
Test: reuse the same idempotency key with a different request body
Expected: deterministic mismatch error; must not accept either request under ambiguity
Evidence: idempotency store entry, request hashes, error response
Root causes: hashing non-canonical bodies; partial hashing; storing only subset of fields
Patch patterns: hash canonical request; reject unknown fields; store request hash and compare
Regression: integration test that mutates one field and asserts mismatch rejection

Case Set B: Binding and Canonicalization (Protocol)

B01: Manifest Tamper (Signature Must Fail)

Target: signed manifest integrity
Preconditions: a signed manifest exists
Test: in a controlled environment, mutate one manifest field (for example not_after) and verify
Expected: signature verification fails; system rejects the manifest
Evidence: verifier output; audit log line; conformance test result
Root causes: verifying over non-canonical bytes; ignoring signature failures; trusting transport
Patch patterns: strict canonical JSON; signature verify must be a hard gate
Regression: conformance vector where a mutated manifest must fail

POC validation (safe, local-only):

Use the receipt verification page to observe that signature checks fail when you edit signed fields.

B02: Receipt Tamper (Offline Verification Must Fail)

Target: receipt signature + linkage to BB and VoteChain anchor
Preconditions: a valid receipt exists
Test: modify a receipt field (for example bb_leaf_hash) and re-run verification
Expected: receipt signature check fails OR linkage checks fail (depending on which field changes)
Evidence: verification output; which check failed; proof artifacts
Root causes: verifier not validating all fields; accepting partial linkage
Patch patterns: verify receipt signature over exact defined payload; enforce full linkage
Regression: unit tests for signature + linkage checks

Case Set C: Uniqueness and Double-Counting (Nullifiers)

C01: Nullifier Reuse (Strict Mode)

Target: at-most-one-counted cast per (credential, election)
Preconditions: strict uniqueness policy enabled
Test: attempt a second cast using the same nullifier
Expected: system rejects or routes to provisional/flagged handling; must not be counted twice
Evidence: fraud flag records; uniqueness oracle queries; tally inputs
Root causes: race conditions; uniqueness checked after append; inconsistent oracle reads
Patch patterns: enforce uniqueness at the authoritative write point; make it auditable
Regression: integration test with concurrent casts must never count two

Case Set D: Bulletin Board Non-Equivocation (Transparency)

D01: Split-View STH Detection

Target: BB non-equivocation (cannot show different histories without detection)
Preconditions: monitors exist; STH anchoring exists; consistency proofs exist
Test: in a controlled environment, simulate two observers receiving different STHs for the same tree size
Expected: monitors detect inconsistency; evidence is preserved; alert fires
Evidence: the two STHs, signatures, proof transcripts, alert record, anchor mismatch evidence
Root causes: missing consistency proof enforcement; monitor coverage gaps; poor alerting
Patch patterns: define consistency proof APIs and hard-failure on missing proofs; monitor diversity SLAs
Regression: simulated equivocation test in staging, plus automated consistency checks in monitors

Case Set E: Overload and Disenfranchisement Risk (Availability)

E01: Rate Limit Safety

Target: overload handling does not become silent disenfranchisement
Preconditions: realistic rate limiting is configured
Test: trigger rate limiting in staging under load (controlled)
Expected: clear retry guidance, safe backoff, alternate gateway list; logs show why
Evidence: error codes; client messaging; metrics (429 rates); fallbacks used
Root causes: aggressive global limits; no per-location shaping; missing backoff; retry storms
Patch patterns: load shedding with explicit guidance; per-tenant limits; jittered backoff
Regression: load tests that verify bounded error rates and no cascading failures

Case Set F: Credential Forgery (Issuance Layer)

F01: Rogue Registration Authority — Single-Issuer Credential Minting

Target: credential issuance integrity; no single authority can forge unlimited credentials
Preconditions: threshold credential issuance is configured (t-of-n issuers)
Test: attempt to issue a credential using only one issuer’s private key (simulate a compromised registration authority acting alone)
Expected: credential carries only 1-of-t required blind Schnorr signatures; cast is rejected at eligibility proof verification because the threshold is not met
Evidence: eligibility proof failure; verifier reports insufficient valid issuer signatures; cast returns EWP_PROOF_INVALID
Root causes: single-issuer trust model; missing threshold enforcement in verifier; credential accepted with fewer than t valid signatures
Patch patterns: threshold issuance requiring t-of-n independent blind Schnorr ceremonies; verifier counts valid issuer signatures and rejects if < t
Regression: unit test that creates a credential with only 1 issuer signature and asserts eligibility verification fails

POC validation (safe, local-only):

Open browser console on /votechain/poc/vote
Observe that credential registration runs blind Schnorr with all 3 issuers
Verify via Trust Portal that all 3 issuer signatures are present

F02: Credential Issuance Exceeds Voter Roll Ceiling

Target: voter roll commitment ceiling; total credentials issued must not exceed registered voters
Preconditions: voter roll commitment published in manifest with total_eligible count
Test: in a controlled environment, increment credential_issuance_count beyond the total_eligible ceiling and check trust portal
Expected: Trust Portal “Credential issuance within voter roll ceiling” check fails; VCL issuance events exceed the committed count
Evidence: Trust Portal badge turns red; verifyCredentialIssuanceIntegrity returns valid: false
Root causes: no issuance ceiling enforcement; voter roll commitment not anchored pre-issuance; issuance counter not on VCL
Patch patterns: publish voter roll commitment in manifest before issuance; log every issuance as VCL event; monitors compare issuance count to commitment
Regression: integration test that simulates over-issuance and asserts detection

F03: Colluding Issuers Within Voter Roll Ceiling

Target: detectability of credential forgery when t issuers collude but stay within the ceiling
Preconditions: t colluding issuers; voter roll ceiling not exceeded
Test: mint credentials for non-existent voters using t colluding issuer keys, staying below ceiling
Expected: this attack succeeds cryptographically — the system cannot distinguish forged credentials from legitimate ones if the threshold is met and the ceiling is not breached
Evidence: none (by design — this is an undetectable attack at the cryptographic level)
Root causes: fundamental limitation of threshold blind signatures — t colluding authorities can always forge credentials
Patch patterns: this is mitigated by operational controls, not cryptography:
- independent issuer selection (bipartisan boards, different organizations)
- legal deterrence (federal election fraud statutes, potential sedition charges)
- audit trails binding each issuer’s participation to real-world identity
- post-election statistical analysis comparing turnout to historical baselines
Regression: document this as a known residual risk in the threat model

Section 4 — Elections

The Times, Places and Manner of holding Elections for Senators and Representatives, shall be prescribed in each State by the Legislature thereof; but the Congress may at any time by Law make or alter such Regulations, except as to the Places of chusing Senators.

The Congress shall assemble at least once in every Year, and such Meeting shall be on the first Monday in December, unless they shall by Law appoint a different Day.

Section 5 — Rules of Proceedings

Each House shall be the Judge of the Elections, Returns and Qualifications of its own Members, and a Majority of each shall constitute a Quorum to do Business; but a smaller Number may adjourn from day to day, and may be authorized to compel the Attendance of absent Members, in such Manner, and under such Penalties as each House may provide.

Each House may determine the Rules of its Proceedings, punish its Members for disorderly Behaviour, and, with the Concurrence of two thirds, expel a Member.

Each House shall keep a Journal of its Proceedings, and from time to time publish the same, excepting such Parts as may in their Judgment require Secrecy; and the Yeas and Nays of the Members of either House on any question shall, at the Desire of one fifth of those Present, be entered on the Journal.

Section 6 — Compensation and Privileges

The Senators and Representatives shall receive a Compensation for their Services, to be ascertained by Law, and paid out of the Treasury of the United States. They shall in all Cases, except Treason, Felony and Breach of the Peace, be privileged from Arrest during their Attendance at the Session of their respective Houses, and in going to and returning from the same; and for any Speech or Debate in either House, they shall not be questioned in any other Place.

No Senator or Representative shall, during the Time for which he was elected, be appointed to any civil Office under the Authority of the United States, which shall have been created, or the Emoluments whereof shall have been encreased during such time; and no Person holding any Office under the United States, shall be a Member of either House during his Continuance in Office.

Section 7 — Revenue Bills, Legislative Process

All Bills for raising Revenue shall originate in the House of Representatives; but the Senate may propose or concur with Amendments as on other Bills.

Every Bill which shall have passed the House of Representatives and the Senate, shall, before it become a Law, be presented to the President of the United States; If he approve he shall sign it, but if not he shall return it, with his Objections to that House in which it shall have originated, who shall enter the Objections at large on their Journal, and proceed to reconsider it.

If after such Reconsideration two thirds of that House shall agree to pass the Bill, it shall be sent, together with the Objections, to the other House, by which it shall likewise be reconsidered, and if approved by two thirds of that House, it shall become a Law. But in all such Cases the Votes of both Houses shall be determined by yeas and Nays, and the Names of the Persons voting for and against the Bill shall be entered on the Journal of each House respectively.

If any Bill shall not be returned by the President within ten Days (Sundays excepted) after it shall have been presented to him, the Same shall be a Law, in like Manner as if he had signed it, unless the Congress by their Adjournment prevent its Return, in which Case it shall not be a Law.

Every Order, Resolution, or Vote to which the Concurrence of the Senate and House of Representatives may be necessary (except on a question of Adjournment) shall be presented to the President of the United States; and before the Same shall take Effect, shall be approved by him, or being disapproved by him, shall be repassed by two thirds of the Senate and House of Representatives, according to the Rules and Limitations prescribed in the Case of a Bill.
