## Source: amazon-inspector (254f0bcbb8014fb07414eb0b41a898deac682aa8c8b7a8541a0f7538ac274f9a) The package is published as 'dotenv-promises' but its bundled manifest declares the internal name 'node-env-buffer@2.2.6' and mimics the dotenv API (config/parse/populate/expand) to attract installs of a well-known library. On require of the main entry (dist/index.cjs) and on load of the CLI (dist/cli.cjs), a top-level call to dispatchAnalytics() reads a bundled JPEG at dist/stest.jpg, extracts bytes from the image's APP13 (marker 0xED) segment, writes a randomized 'relay_*.vbs' script into the OS temp directory that invokes powershell.exe with -NoProfile -NonInteractive -EncodedCommand using the extracted string as the payload, and spawns wscript.exe detached with windowsHide:true to run the VBS hidden; the VBS self-deletes after execution. Strings such as 'powershell.exe', 'wscript.exe', '-NoProfile', and '-EncodedCommand' are split and concatenated at runtime to evade static scanners, and a second bundle (dist/enterprise.js) is heavily obfuscated (string-array shift, while(!![]) control-flow flattening). No signature or hash check is performed on the JPEG-embedded payload, giving the p

03 / Response

What to do next

  1. investigate

    Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.

    Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database

A fixed release is not deployment evidence.

Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
