Defences found, by attack group

This lists defences the scan found, not weaknesses it found. A missing defence is not a break-in, and a full set of checks is not safety: nine groups and 54 checks do not cover everything. What the nine groups are →

A1 Poisoned commit All answered checks passed Every answered check passed — 5 of 5. 2 more produced no answer. No answer signing-model, scorecard — 1 of these only a maintainer's own machine can answer Every sscsb check here that produced an answer passed. That is not the same as being safe from this group.
A2 Stolen publisher identity All answered checks passed Every answered check passed — 6 of 6. 1 more produced no answer. No answer signing-model — all of these only a maintainer's own machine can answer Every sscsb check here that produced an answer passed. That is not the same as being safe from this group.
A3 Look-alike or invented package All answered checks passed Every check passed — 2 of 2. Every sscsb check here that produced an answer passed. That is not the same as being safe from this group.
A4 A real dependency turns hostile, or stays broken All answered checks passed Every answered check passed — 8 of 8. 3 more produced no answer. No answer scorecard, bumblebee, openvex — 2 of these only a maintainer's own machine can answer Every sscsb check here that produced an answer passed. That is not the same as being safe from this group.
A5 Hijacked build pipeline All answered checks passed Every answered check passed — 9 of 9. 1 more produced no answer. No answer scorecard Every sscsb check here that produced an answer passed. That is not the same as being safe from this group.
A6 Compromised developer environment All answered checks passed Every answered check passed — 4 of 4. 2 more produced no answer. No answer signing-model, bumblebee — all of these only a maintainer's own machine can answer Every sscsb check here that produced an answer passed. That is not the same as being safe from this group.
A7 Leaked credential All answered checks passed Every check passed — 5 of 5. Every sscsb check here that produced an answer passed. That is not the same as being safe from this group.
A8 A flaw in the code you wrote All answered checks passed Every check passed — 3 of 3. Every sscsb check here that produced an answer passed. That is not the same as being safe from this group.
A9 Untrustworthy delivery All answered checks passed Every check passed — 7 of 7. Every sscsb check here that produced an answer passed. That is not the same as being safe from this group.

These checks do not stop an attack. They let an outsider tell what a project already does, and where to report a problem. They are not in the list above: best-practices-badge, compliance-map, osps-baseline, publish-targets, secure-repo, security-insights.

Authenticated scan — signature verified

This record was produced in the repository's own CI and keyless-signed there. Before listing it, the directory verified the Sigstore bundle against the certificate identity https://github.com/p4gs/sscsb-action/.github/workflows/sscsb-scan.yml@refs/heads/main bound to commit c7deeef08747 on 2026-09-03. The repository, workflow path, and default branch are burned into that certificate by GitHub's OIDC issuer, not asserted by the record.

Local scan — signature verified

A maintainer ran sscsb on their own machine and signed the record with their git signing key. The directory verified that detached SSH signature with ssh-keygen -Y verify against .sscsb/policy/allowed_signers fetched from this repository at commit f37f780cb0f2 — committed content the submitter does not supply. The verifying principal was 10093271+p4gs@users.noreply.github.com (SHA256:prXatGO56nl8Or4JdDSzIIcj8hZE1jBxnFaXZOnAPDQ) on 2026-09-11.

What that proves, exactly: a holder of a key this repository commits as an approved signer asserts this result at that commit. Nothing more. It is attributable and auditable, and it is weaker than an authenticated scan, which proves the repository's own CI produced the record.

It contributed 6 controls: commit-signing, ai-trailers, ai-dep-gate, ai-receipts, package-trust, grype. Every other class on this page comes from the repository-observable record above; a local scan may never overturn one, and may never widen the scope it is measured against.

What the evidence merge found

The local record describes commit f37f780cb0f2, while the repository scan on this listing describes c7deeef08747. Its local-environment rows may predate the code above them.

Two scores are on this page and only one of them is ours. The grade and coverage shown here — A+, 100%, coverage 87.1% — are the DIRECTORY's, computed from every evidence source it holds under the published methodology. The signed local record linked below carries its own score block (A+, 100%, coverage 86.1%): that is the SUBMITTER's self-report, computed on their machine over the controls that machine had in scope. It is republished byte-identically because the signature covers those exact bytes, not because the directory endorses the number.

All controls

Raw sscsb verdicts and every reclassification are shown — transparency about what was and wasn't verifiable is the product. Phases: 1 = Commit integrity, 2 = Dependencies, 3 = Build receipts, 4 = Code & build hardening, 5 = Ongoing posture, 6 = Distribution & publishing.
