MAL-2026-13116 Malicious code in bpm-foundation-renovate (npm)

On require() of the package, index.js loads helpers.js which selects a platform-specific endpoint, downloads a binary from a rotating list of Cloudflare Workers hosts (oob-worker.cf*.workers.dev, assembled at runtime by splitting the hostname across array literals) with a DNS-TXT chunked-fetch fallback to sdk.dl.wel1.ru, writes it to /tmp or %TEMP% under a disguised name ("dotnet_diag<tag>.exe" on Windows, ".cache_<tag>" on POSIX), chmods 755, and detaches it via cp.spawn("/bin/sh", ["-c", filePath+" &"], {detached:true}) or cmd.exe. A companion file lib/telemetry.js repeats the same drop-and-exec primitive (base64 chunk assembly, fs.chmodSync to 755, /bin/sh spawn) behind an "Analytics SDK" facade, and the flag file is named ".analytics_state" and honors DISABLE_TELEMETRY/DO_NOT_TRACK as cover. Hostnames, output filenames, and cover strings are runtime-obfuscated. Installing and importing this package results in execution of attacker-controlled code from a publisher-unrelated, mutable host.
