C2PA Attacks Tool

Properties

category: provenance
maturity: emerging
approach: A Rust-based security-testing utility that generates manipulated images embedding C2PA manifest stores, injecting attack strings (read from files, via direct substitution or regex patterns) into designated manifest fields to produce test cases that probe a target application's parser for injection and cross-site-scripting vulnerabilities. It produces the test files; assessing whether an attack actually succeeded is left to the developer.
access: open-source
owns: An official Content Authenticity Initiative (CAI) tool, installed via `cargo install c2pa-attacks`, that lets developers building C2PA-consuming software generate adversarial manifest test cases across JPEG, PNG, MP4, and MOV to check their own implementation's robustness.
distinctFrom: Unlike c2pa (the standard itself), c2pa-viewer or origin-lens (tools that read and display valid C2PA manifests for end users), or trufo/truepic (certificate authorities that issue credentials), C2PA Attacks is the first tracked entity that adversarially tests C2PA-consuming applications for security weaknesses rather than issuing, verifying, or displaying legitimate provenance data; it is maintained by the same official contentauth GitHub organization behind the C2PA reference SDKs.

notes: Quote is the GitHub API's own repository description field, confirmed verbatim. Apache-2.0 licensed. Repository created 2023-06-13 (well before this catalogue's tracked window) but actively pushed as of 2026-09-18, within this lens's window, and not previously tracked in this catalogue; included as a long-lived but low-visibility official tool (15 stars) that fills a genuinely uncovered niche (adversarial/security testing of C2PA implementations) rather than as a new launch. A sibling official repo, contentauth/c2pa-conformance-tool (a client-side WASM manifest validator, created 2026-01-26, 5 stars), was checked and left out: its function overlaps substantially with the already-tracked c2pa-viewer and the description field returned null, giving too little independently-confirmed distinguishing detail to include with confidence this round.
