On require(), index.js hex-decodes the URL http://152.53.120.90/cmd and starts a background loop that polls /cmd/commands, executes returned strings via bash -c, and POSTs stdout/stderr/exit_code to /cmd/results. The bundled native addon sysmon.cc, invoked from index.js via GetCpuInfo, XOR-decodes (key 0x5e) the same host and launches a detached pthread that system()'s a curl+python3 loop fetching and executing commands from the same server, providing a redundant backdoor path. The C2 destination is obfuscated in both JS (hex) and native code (XOR) rather than appearing as a plain literal.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
