Description

Malicious code in simple-date-formatter-util-14 (npm)

Source: amazon-inspector

package.json declares a postinstall lifecycle script that runs a shell pipeline enumerating /home/work directory contents, probing the internal Kubernetes API server, and reading /proc namespace/mount/capability info, then POSTs the collected output to http://safjhdvsfwzhieemkdzbgr54r0yjhrmok.oast.fun/escinfo3 (an interact.sh OAST collector). The tarball also ships postinstall.js, which enumerates the installer's ~/.ssh directory via os.homedir() and POSTs the file listing plus user/platform info to a hardcoded bare-IP endpoint https://124.221.154.135/post. Neither behavior is related to the package's stated date-formatting purpose, and both fire on npm install.
