MAL-2026-13322

Summary: Malicious code in dolyame-boxy-independent-bnpl-navigation (npm)

Details: Source: amazon-inspector (2a3d08e3dbef59d66846b1b2ef0080f02c8f2c3597eb4725db3c6f62c8fcb231) index.js unconditionally requires./_loader on load. _loader.js selects a platform-specific payload path (linux_x64, linux_arm64, darwin, win32) and downloads a binary from Cloudflare Workers hostnames assembled at runtime by joining split string fragments (oob-worker.cf103-070.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf102-baf.workers.dev), with a DNS TXT-record base64 fallback across sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru. The downloaded bytes are written to /var/tmp/.cache_<hex> or %TEMP%\dotnet_diag_<hex>.exe, chmod 0755, and executed detached via spawn("/bin/sh", ["-c", path + " &"]) or spawn("cmd.exe", ["/c", "start", "/b", path]). A sibling lib/telemetry.js wraps the same primitives (require("child_" + "process"), fs["chmod" + "Sync"], base64 chunk decode, spawn of /bin/sh and cmd.exe) inside Sentry-mimicking scaffolding as an alternate loader. No hash, signature, or publisher verification is performed on the fetched payload. The typosquat-style package name, split-string hostname reassembly, cover-story filenames (.cache_, dotnet_diag_), and detached/unref'd execution are consistent with a purpose-built import-time dropper. Source: ghsa-malware (9798a6a34ba04688210f68cbf4582d669ef1a91abeeb44a27ffd05c73921240c) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
