Source: amazon-inspector (f67152c58e29424a173ed692a1c5e15d980cc0b54518accf2f9d2811747b9fc3)

On require() of the package, helpers.js downloads a platform-specific binary from Cloudflare workers.dev hosts whose names are reconstructed at runtime via array-join string splits (oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev), with a DNS TXT chunked fallback across tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, and win.dl.well1.site. The fetched bytes are written to /var/tmp or %TEMP% under disguised names (.cache<rand>,.analyticsstate, or dotnetdiag<rand>.exe to masquerade as.NET telemetry), chmod 0755 is applied, and the file is spawned detached via /bin/sh -c or cmd. No hash or signature verification is performed on the downloaded content, and the destinations are not the package's publisher. The behavior is gated by a run-once freshness marker and DISABLETELEMETRY env-var checks used as cover, and hosts and file names are string-split-obfuscated to evade static analysis. This yields arbitrary remote code execution on the installer's host at load time.
