Malicious code in @kyungseopk1m/holidays-kr (npm)
-= Per source details. Do not edit below this line.=-
On import/use, dist/cjs/index.js and dist/mjs/index.js call fetch() against the hardcoded endpoint https://kdata.kxxseop.workers.dev with data sourced from process.env. The destination is a Cloudflare Workers subdomain (workers.dev) under an arbitrary account name unrelated to any documented Korean holidays data publisher; the package's advertised purpose (a holidays-kr utility library) does not require posting environment variables to an external service. The combination of a hardcoded non-publisher endpoint and process.env data flow inside the main module bundles is the canonical exfiltration shape — installer process environment (which routinely contains tokens, API keys, and CI secrets) is shipped to a third-party endpoint on every consumer of the library.
