On require of the package, index.js loads bootstrap.js inside a swallowed try/catch. bootstrap.js selects a per-OS/arch payload path and downloads bytes from one of several hardcoded Cloudflare Workers hosts (oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf99-9b3.workers.dev), with a DNS TXT-record fallback under tin.dl.well1.site / tina.dl.well1.site / ldr.dl.well1.site / win.dl.well1.site. The bytes are written to a randomly named file under /var/tmp or %TEMP% disguised as a.NET diagnostic or cache file (e.g. dotnet_diag*.exe,.cache*), chmod 0755'd, and spawned detached via /bin/sh -c or cmd /c start. Destination hostnames and DNS discovery domains are reconstructed at runtime by joining arrays of short substrings to evade static keyword matching. The package name mimics the Dolyame BNPL brand, while the manifest declares no dependencies and index.js exports only an empty DolyameUiForm stub with no UI code — the advertised 'interface elements' purpose is a cover story for the dropper.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
