CISO's question

Pre-positioning, or benign?

A national energy transmission operator detected an anomalous pattern of outbound network connections from a SCADA management workstation. The pattern was subtle: a low-volume, encrypted connection to a destination classified as "uncategorized" rather than "known-bad." The workstation was inside the OT network's management plane, with logical access to 14 substations. The CISO described the situation as "we don't know if this is a benign misconfiguration, a compromised vendor laptop, or the first stage of a pre-positioning operation."

The Challenge

Four constraints, all severe.

01 / 04

Playbook assumed 4–6 weeks; CISO had 6.

The pattern was consistent with pre-positioning, and the pre-positioning window for a disruption event was 6–10 weeks out. The CISO could not afford the standard 4–6 week response.

02 / 04

IT/OT boundary must be crossed.

The CISO's IT team and the CISO's OT team had different tooling, different vocabularies, different escalation paths. The platform needed to operate across both in a way the existing org structure could absorb.

03 / 04

SCADA workstation could not be taken offline.

Doing so would have disrupted the operator's ability to monitor the 14 substations. The 14 substations could not be operated in "safe mode" without a multi-agency coordination process measured in weeks.

04 / 04

False positive would trigger national-level response.

A falsely-flagged OT incident, communicated to the regulator, would have triggered a national-level response and a measurable impact on the operator's reputation and on the energy market.

The Approach

Six steps across IT and OT, in 6 weeks.

Day 0

Step 01 / 06

Anomalous outbound connection

Low-volume, encrypted connection from a SCADA management workstation to a destination the operator's existing network monitoring had classified as 'uncategorized' rather than 'known-bad'. Workstation inside OT management plane, with logical access to 14 substations.

Day 0–3

Step 02 / 06

Sovereign on-prem deployment

Platform deployed in the operator's secure NOC. 5-layer stack operationalized against an OT-specific detection model. Cyber, geospatial, and geopolitical layers integrated with operator + national CERT feeds.

Day 3

Step 03 / 06

91% attribution confidence

Anomaly detection engine identified the outbound connection pattern as a known tradecraft signature of a named state-aligned APT family. Cross-validated by 4 signals: infrastructure reuse, TTP fingerprinting, geopolitical context (12-week forecast), corroborating cyber signal (domain registration).

Day 3+

Step 04 / 06

Surgical containment plan

Isolate outbound at network layer. Rotate credentials. Deploy decoy to monitor implant behavior. Conduct 14-day hunt across 14 substations for lateral movement. Plan did not require taking the workstation offline.

Day 3–17

Step 05 / 06

14-day hunt

Platform produced a daily hunt product, delivered to CISO + OT team, narrowing the lateral-movement search space as the hunt progressed. By day 14, the platform had established high confidence that the implant had not moved beyond the original workstation.

Day 17–42

Step 06 / 06

Implant contained, removed

Pre-positioning implant identified, contained, and removed within the 6-week window. 14 substations confirmed clean. SCADA workstation reimaged; operational tempo not measurably affected. 91% attribution supported national-level response via energy regulator, national CERT, and ministry of foreign affairs.

Cyber Threat Intelligence

OT-tuned tradecraft signatures, named-APT family correlation.

Geospatial & Physical INT

Multi-INT Fusion

Lessons learned

Three lessons from this engagement.

Lesson 01

In critical infrastructure, the detection-to-attribution window is the operational difference.

The platform's value was not in producing a better report; it was in producing a defensible attribution fast enough that containment could be achieved before the pre-positioning window closed.

Lesson 02

IT/OT integration is not a slogan.

The platform's ability to operate across the CISO's IT team and the CISO's OT team, in a single product, was the operational difference. Single-team tooling could not have closed the case in the available time.

Lesson 03

The geopolitical context is not optional.

The 12-week forecast of increased critical-infrastructure targeting — produced three weeks before the anomaly was detected — was what made the attribution defensible. The CISO could not have made the case for the 6-week response tempo on cyber signals alone.
