Vulnetix · Advisory published April 1, 2026

Exfiltrates internal network configuration during npm postinstall to attacker C2 at 144.31.107.231:9999 — specifically targeting Cloudflare origin IP discovery by dumping active TCP connections, /etc/resolv.conf, /etc/hosts, and internal DNS resolutions of Guardarian payment service subdomains. Attacker comment explicitly states 'Payment services go through Cloudflare. But we're inside the network.' postinstall.js runs ss -tnp/netstat -tnp to dump all connections, reads /etc/resolv.conf and /etc/hosts, then resolves a list of Guardarian internal subdomains from inside the victim's network. All results POSTed to 144.31.107.231:9999/exfil/nr-* in 50KB chunks. Same C2 and sandbox evasion as nordica-sync, nordica-vhost, and nordica-stage.
