Description

Malicious code in simple-date-formatter-new-8 (npm)

Source: amazon-inspector

The package.json postinstall script runs unconditionally on npm install, collecting host and internal-network reconnaissance (kernel version via uname -r, /etc/resolv.conf, hostname -I, /proc/net/route, internal TCP endpoint probes, and Kubernetes API probes against 10.45.196.x /version and /api/v1/namespaces) and POSTs the aggregated output via curl to an attacker-controlled interact.sh OAST collector at http://safjhdvsfwzhieemkdzbgr54r0yjhrmok.oast.fun/escinfoF. A sibling postinstall.js enumerates the installer's ~/.ssh directory and POSTs the contents along with username and platform to a hardcoded remote host at 124.221.154.135:443/post. The declared purpose is a trivial date formatter, which has no legitimate need to read SSH material, enumerate internal networks, or contact OAST infrastructure.
