The same loader is reachable via the bin CLI dot2env (dist/cli.cjs), which also re-requires the main module and re-triggers the loader. Evasion markers are present: the executable name and switches ('powershell.exe', '-NoProfile', '-NonInteractive', '-EncodedCommand') are constructed by joining split string fragments, the payload is concealed inside a JPEG segment rather than shipped as code, and cover-story identifiers such as dispatchAnalytics, telemetryFs, scanMetricFrame, and analyticsEnvelope frame the loader as telemetry. The bundle in dist/cli.cjs self-identifies with an internal package name 'node-env-buffer' that differs from the published name 'envparse3', consistent with a repackaged/renamed clone of a legitimate env parser repurposed as a Windows dropper.\n\n## Source: ghsa-malware (cf6625a76e25d09cfc8b39996f8ecacccd8d5c7cff8d412547ba534b2fd29d17)\nAny computer that has this package installed or running should be considered fully compromised.
