OpenSSF/OSV advisory MAL-2026-17514 confirms this npm version as malicious. Despite being advertised as a WCAG contrast checker, the package executes a self-invoking function at module load that runs host reconnaissance commands (whoami, id, hostname, uname -a, ls -la /, pwd, cat /etc/os-release) and collects filtered environment variables, then exfiltrates the results via DNS subdomain requests to davdpb8lhot13kgmnhp0863x9g83mpswq.oast.live and HTTP GET parameters to...

## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

Despite being advertised as a WCAG contrast checker, the package executes a self-invoking function at module load that runs host reconnaissance commands (whoami, id, hostname, uname -a, ls -la /, pwd, cat /etc/os-release) and collects filtered environment variables, then exfiltrates the results via DNS subdomain requests to davdpb8lhot13kgmnhp0863x9g83mpswq.oast.live and HTTP GET parameters to webhook.site/0492a36c-4d7b-408a-865c-226db25987ba. The exfiltration fires on any import of the package. Additionally, the module exports factories named after Wix Thunderbolt internal registries (thunderboltRegistry, siteAssetsRegistry, editorRegistry, corvidRegistry) and ships a registry-manifest.min.json pointing at static.parastorage.com/unpkg/minimal-a11y-contrast-check@1.0.0, impersonating internal Wix build infrastructure to be resolved via dependency confusion. A hardcoded 'internetbrands' tag embedded in the exfiltration payload indicates targeted reconnaissance.
