<strong>INTERNAL LATERAL MOVEMENT DETECTED — NOVA-CORE NETWORK</strong>

BLUF: IPS system detected a lateral movement scan from 192.168.1.9 probing five ports on 192.168.1.138 within 60 seconds on the nova-core network segment. Source and target identity unconfirmed; extent of successful penetration unknown. Immediate network isolation and host forensics required.

DETAILS

  • Detection: IPS logged lateral_movement threat signature at 2026-10-04; source host 192.168.1.9 initiated port scans against 192.168.1.138 (five distinct ports within 60-second window).
  • Network Context: Internal traffic only (192.168.x.x CIDR); scan originated and terminated within Jordan’s infrastructure, not external ingress.
  • Target Host: 192.168.1.138 identity and function not yet confirmed; no data on whether ports answered or connections succeeded.
  • Source Host: 192.168.1.9 identity unknown; could be legitimate internal asset, compromised device, or rogue VM.
  • Detection Status: Flagged but not yet contained; both hosts remain active on network.

IMPACT

  • Scope: Nova-core network segment; potentially multi-host compromise if source was itself compromised.
  • Affected Systems: 192.168.1.138 and any systems on the 192.168.1.x segment if lateral movement succeeded.
  • Risk Level: Unknown — lateral scans precede lateral movement exploits; whether this was reconnaissance or active exploitation cannot be determined from IPS signature alone.

RECOMMENDED ACTIONS

  1. Immediate (next 5 minutes): Identify both hosts (192.168.1.9 and 192.168.1.138) — what OS, what service, who owns it.
  2. Containment: Isolate 192.168.1.138 from the network; do not terminate connections yet (preserve forensics).
  3. Forensics: Pull IPS packet logs for the 60-second window — confirm which five ports, which succeeded, what application protocols appeared.
  4. Source Investigation: Log into 192.168.1.9 (or image it if it’s a server); check for signs of compromise (unexpected processes, SSH keys, cron jobs, network configuration changes).
  5. Segment Review: Confirm network segmentation is working; nova-core should not trust arbitrary internal scans.
