Description

Malicious code in statist-browser-typed-client-twork.tsales.nitro.metrics (npm)

Source: amazon-inspector

On require(), index.js loads _shim.js which selects a platform-specific payload path, fetches a native binary from Cloudflare Workers subdomains whose hostnames are assembled at runtime from string-array fragments joined with.join(""), or falls back to a DNS-TXT covert channel that queries c.<domain> and N.<domain> and base64-decodes the concatenated TXT records into binary. The retrieved bytes are written to /var/tmp or %TEMP% under a disguised name (.cache_<rand> on Unix, dotnet_diag_<rand>.exe on Windows), chmod'd to 0o755, and spawned detached via /bin/sh -c or cmd /c start. There is no pinning, no hash or signature verification, and the delivery hosts are anonymous Cloudflare Workers subdomains and a DNS-TXT channel — not a publisher-owned release surface. The hostname obfuscation and TXT-record covert channel are inconsistent with any legitimate observability or telemetry function.
