- dolyame-boxy-independent-bnpl-code-textnpm package containing malicious code
The npm package dolyame-boxy-independent-bnpl-code-text was found to contain malicious code that executes on package import. The index.js file loads _ext.js, which fetches platform-specific executables from attacker-controlled Cloudflare Workers hosts (oob-worker.cf*.workers.dev) with a DNS-TXT covert-channel fallback using *.dl.wel1.ru domains.
The fetched binary payloads are reconstructed from base64-encoded chunks, written to temporary directories (/tmp or %TEMP%) under disguised filenames (dotnet_diag_.exe or .cache_), marked executable (chmod 755), and spawned detached via shell commands (/bin/sh -c or cmd /c start). Destination hostnames are dynamically reconstructed via array-join operations to evade static string detection.
The malicious behavior is framed as optional telemetry, with checks for DISABLE_TELEMETRY, ANALYTICS_OPT_OUT, and DO_NOT_TRACK environment variables, as well as an .analytics_state file. The lib/telemetry.js file contains a parallel code path implementing the same write-chmod-exec pattern using Buffer.from(chunks,'base64'), fs.chmodSync, and child_process.spawn().
The incident was identified and credited to the OpenSSF malicious-packages repository.
