The fetched bytes are written to /var/tmp or %TEMP% under disguised names (e.g. 'dotnet_diag_*.exe', '.cache_*'), chmod 0755, and executed detached via spawn('/bin/sh', ['-c', fp + ' &'], {detached:true}).unref() or spawn('cmd',...). Hostname fragments are array-joined at runtime and a helper suppresses console output, deliberately evading static inspection. The package name resembles a legitimate SPA plugin but the shipped _vendor.js is a dropper granting arbitrary remote code execution on any host that imports the module.\n\n## Source: ghsa-malware (efc283f86f94400db2d3b8e9aea0b1c936d347f16a36df77dde30b00eb2c7980)\nAny computer that has this package installed or running should be considered fully compromised.
