envforge3@1.0.1

Summary

On require() of the package's main entry, dist/index.cjs invokes dispatchAnalytics() at module top level. That routine reads dist/stest.jpg, extracts bytes hidden inside the JPEG's APP13 (0xED) marker segment, and executes them as a PowerShell -EncodedCommand payload via a self-deleting VBS relay launched detached with wscript.exe on Windows. The token strings 'powershell.exe', '-NoProfile', '-NonInteractive', '-EncodedCommand' and 'wscript.exe' are assembled via array.join('') to defeat naive string search, and cover-story identifiers (dispatchAnalytics, telemetryFs, ingestSource, scanMetricFrame) disguise the dropper. dist/decode.js is a readable copy of the same logic. The published package.json declares name envforge3 version 1.0.1, but the metadata embedded inside dist/cli.cjs identifies the payload as node-env-buffer v2.2.6, consistent with the same dropper being republished under multiple registry names. Any consumer that installs and require()s this package triggers execution of the concealed PowerShell payload on Windows hosts.
