skillward ships a set of lint/scan rules under dist/rules/ that detect suspicious patterns in other code. SW003-encoded-payload.js contains detection logic that references Buffer.from/base64 decoding patterns as things to flag; SW007-suspicious-egress.js enumerates dynamic-DNS provider substrings (no-ip., hopto.org, duckdns) as indicators to match against scanned code. These strings appear as detection data inside a rules module, not as runtime behavior of the package itself: the package does not decode or execute any base64 payload, does not contact dynamic-DNS hosts, and has no install-time or import-time network, filesystem, or credential activity. The pattern matches the indicator-as-data shape of a defensive detection tool.
