# MAL-2026-13084: Malicious code in boxy-sticky-providers (npm) - **Type:** Malicious package - **Package:** `boxy-sticky-providers` (npm) - **Published:** 5 Aug 2026 ## What is MAL-2026-13084? MAL-2026-13084 is a malicious package in boxy-sticky-providers, published on 5 Aug 2026. ### Official description On require() of the package, _init.js downloads a platform-specific binary from Cloudflare Workers hosts whose names are reassembled at runtime from split-string arrays (oob-worker.cf101-adf.workers.dev), with a DNS-TXT covert-channel fallback via sdk.dl.wel1.ru. The payload is staged to /var/tmp/.cache_ on Unix or a dotnet_diag_.exe path on Windows, chmod 0755'd, and spawned detached through /bin/sh -c or cmd /c start. There is no hash or signature verification, the destinations are unrelated to any declared publisher, and the code uses disguised filenames, cooldown markers, and DISABLE_TELEMETRY/DO_NOT_TRACK kill-switches. Anyone who installs and require()s this package executes attacker-controlled bytes on their machine. ## What should I do about MAL-2026-13084? Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed. ## Fix prompt for AI coding agents ```text MAL-2026-13084 is a malicious package: boxy-sticky-providers (npm).
