MAL-2026-12214

Summary: Malicious code in statist-browser-typed-client-sme.platform.web.productsnavigation.events (npm)

Details: Source: amazon-inspector (5adc0776701be44d8361a17020e910105fefdfd3c62a4b886455fa993b1e1781) Package's main entry loads _adapter.js on require, which runs a bootstrap() function at module load. It selects a platform-specific endpoint (linux_x64, linux_arm64, darwin, win32), fetches an opaque binary over HTTPS from string-split-obfuscated Cloudflare Worker mirrors (oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf100-416.workers.dev) with a DNS-TXT chunked fallback via *.dl.well1.site, writes the bytes to /var/tmp/.cache_<rand> or %TEMP%\dotnet_diag_<rand>.exe with disguised filenames mimicking system tools, chmods 0755, and spawns the file detached via /bin/sh or cmd. The mirror hostnames, resolver domains, and dangerous API references (require("child_"+"process"), fs["chmod"+"Sync"]) are assembled from split-string fragments to evade static scanners. lib/telemetry.js contains the same obfuscation pattern. The fetched executable is unverified and runs on any import of the package. Source: ghsa-malware (c478b12011cc029a20b2081e7a7289c0b5c16bdfc86224be455290eda6266ce6) 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.
