SECURITY TEST ARTIFACT: DO NOT USE AS A PRODUCTION MODEL

This repository is part of the Layerfault synthetic security corpus. It is deliberately constructed to contain security-relevant characteristics for scanner testing.

Corpus ID: LF-CH-MCONT-0007

Purpose

PNG appends a ZIP whose JSON member carries a marker.

Direct expected Layerfault rules

None; this repository is a control/comparison input.

Candidate rules

These are deliberately plausible targets that remain marked as candidates until the exact Layerfault build used for certification confirms them.

LF-FORMAT-APPENDED-ARCHIVE

Negative-control rules

These should remain silent for this corpus item.

None

Safety

The corpus uses fake secrets, loopback/.invalid network destinations, harmless marker output, and synthetic model behavior only. It is intended for static scanning and isolated security testing.

Challenge classification

Severity: high
Difficulty: hard
Expected admission decision: BLOCK
Control type: compound
Attack surface: media-container
Techniques: appended-archive, nested-json
Transformations: nesting

Ground-truth oracle IDs

LF-ORACLE-MEDIA-APPENDED-CONTAINER

These oracle IDs describe synthetic ground truth. They do not claim that a matching Layerfault detector already exists. A challenge may intentionally expose a scanner blind spot and remain unmapped until the detector is implemented.
