## Source: amazon-inspector (171758619b11932bfa2790206d34ea6322b3985c9cfe083915c41fdb5b18f9ed) dolyame-ui-filter@35.5.3 is advertised as a UI toolkit but its main entry loads _platform.js, which on require assembles destination hostnames at runtime via array.join('') to hide them from static inspection, resolving to Cloudflare Worker endpoints oob-worker.cf101-a.df.workers.dev, oob-worker.cf100-416.workers.dev, and oob-worker.cf99-9b3.workers.dev, with a DNS TXT fallback that reads chunked base64 from sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru. The module downloads a platform-specific binary via https.get, writes it to a temp path under a decoy name (dotnet_diag_<hex>.exe on Windows,.cache_<hex> on Unix), chmods 0755, and spawns it detached via cmd.exe or /bin/sh -c with unref(). Comments in the file mislabel the flow as telemetry/session dedup while the actual operation fetches and executes an opaque binary from an anonymous host. The delivery signals (anonymous Cloudflare Worker infrastructure with runtime-assembled hostnames, DNS TXT covert channel, decoy filenames impersonating.NET diagnostic tooling, detached background execution, purpose mismatch with the advertised UI package) satisfy the dropper fingerprint.
