If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

The package's package.json postinstall script curls cloud instance-metadata endpoints (AWS IMDS at 169.254.169.254/latest/meta-data/sts-credential, Alibaba/Tencent metadata at metadata.tencentyun.com and 169.254.0.23) into /tmp files and POSTs their concatenated contents plus `ls -la /data/` output to a remote collector (placeholder host YOUR_BURP_SERVER). The tarball additionally ships postinstall.js containing getSSHKeys(), which reads ~/.ssh from the installer's home directory along with username/platform metadata and POSTs the payload over HTTPS to a hardcoded bare IP 124.221.154.135:443/post. Installing the package runs the lifecycle exfiltration automatically; the SSH-key harvester is bundled dropper code aligned with the same intent. The trivial 'date formatter' name and the presence of a placeholder collector indicate a PoC/typosquat stub in an ongoing credential-theft campaign.
