Summary
Malicious code in wiasdcxc (npm)
Details

wiasdcxc is a dependency-confusion package (versions up to 99.0.1) from the same campaign as troubleshooting (MAL-2026-17641): a postinstall script runs beacon.cjs, which POSTs the installing host's name, install path and working directory to a hard-coded collector, and index.js, byte-identical to the troubleshooting payload (sha256 a86a4da763bbb34c16f361abe7aab66d5df591b66867ac8160041f932159b08d), does the same when imported.
