Malicious code in dolyame-ui-inputrange (npm)
--- _-= Per source details.

No native source is shipped in the tarball and the fetched bytes are opaque. lib/telemetry.js, re-exported by the package's main entry, duplicates the same dropper primitives (base64-decoded chunks written to disk, chmod 755, /bin/sh -c spawn) behind an "Analytics SDK" cover story, ensuring execution persists even if _init.js is stripped. Runtime string reassembly of module names (require("child_"+"process")) and destination hosts, plus opt-out env-var gates (DISABLE_TELEMETRY, ANALYTICS_OPT_OUT, DO_NOT_TRACK) and a TTL cache file, are used to evade static analysis and hide repeat executions.
