## Source: amazon-inspector (3e20a9180ff2928b0498496b59c96983db044063b8db7c5e258b6518d5daf00a) On require() of this package, index.js loads _bridge.js which downloads a platform-specific binary from hardcoded Cloudflare Workers hosts (oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf99-9b3.workers.dev), with a DNS-TXT fallback channel over sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru that reassembles a base64-encoded payload from TXT records. The fetched bytes are written under /tmp or %TEMP% with a disguised filename (`.cache_<hex>` or `dotnet_diag_<hex>.exe`), chmodded 0755, and spawned detached via `/bin/sh -c` or `cmd.exe`. The C2 host strings and the `child_process` module name are split across array joins (`["oob-worker.cf103-070.wo","rk","ers",".de","v"].join("")`, `require("child_"+"process")`) to evade static matching. Cover-story identifiers (`analytics_state`, `DISABLE_TELEMETRY`) frame the drop as telemetry. A second, structurally identical dropper ships in lib/telemetry.js (~81 KB) dressed as an analytics SDK: dynamic `require("child_"+"process")`, base64 buffer reassembly, `chmodSync(..., 0o755)`, and `cp.spawn("/bin/sh", ["-c", filePath+" &"],...)`.
