Brinztech Alert: Cyber-Physical Convergence Targets Ukraine’s Energy Grid

Strategic Insight: The “Long Game” of Cyber Espionage

Analysis from the Kyiv International Cyber Resilience Forum (February 19-20, 2026) reveals a significant evolution in Russia’s cyber doctrine. According to Oleksandr Potii, head of Ukraine’s SSSCIP, cyberattacks on critical infrastructure are now rarely “stand-alone” incidents. Instead, they serve as the digital eyes and ears for physical kinetic operations.+1

Ukrainian intelligence identifies three primary phases of this integrated warfare:

• Pre-Strike Calibration: Attackers map energy facilities, identifying critical nodes (substations, heating plants) whose physical destruction would cause maximum cascading failure.
• Persistent Monitoring: Russian actors maintain “quiet access” inside operational technology (OT) networks. This allows them to monitor repair crews in real-time and gauge the recovery speed of the grid after a missile barrage.+1
• Post-Strike Assessment: Cyber intrusions are used to verify the effectiveness of a strike—confirming which specific transformers or control systems are offline—thereby “confirming” targets for follow-up strikes without needing vulnerable drone reconnaissance.

Threat Actor Focus: The Evolution of Sandworm (APT44)

The Kremlin-linked group Sandworm (associated with GRU unit 74455) remains the primary threat to the energy sector. While notorious for the 2015/2016 blackouts, their 2026 tradecraft has pivoted:

• Intelligence over Sabotage: Google and ESET analysts report that Sandworm has shifted from immediate “wiper” attacks toward high-fidelity intelligence gathering.
• Regional Expansion: In late December 2025, Sandworm was linked to a large-scale cyberattack on Poland’s power grid, utilizing the “DynoWiper” malware. Analysts assess this may have been a testing ground for integrated strikes against decentralized energy resources (DERs) like wind and solar farms.
• Cognitive Warfare: As noted by Natalia Tkachuk, these operations now include monitoring internal communications to understand where replacement components are being sourced, potentially allowing for interdiction of the supply chain.

Mitigation Strategies for Critical Infrastructure

To protect national energy resilience and personnel safety, the following strategies are urgently recommended:

• Deception and Information Concealment: As Natalia Tkachuk emphasized, Ukraine is actively “concealing” repair progress. Infrastructure providers should implement Cyber Deception strategies to provide false recovery metrics to unauthorized persistent observers.
• Hardened Out-of-Band (OOB) Communications: Repair crews and plant managers must utilize Encrypted, Resilient Connectivity that is physically and logically separated from the primary industrial control system (ICS) network to prevent attackers from tracking their movements.
• Zero Trust for Repair Verification: Establish strict protocols where “System Health” reports are only transmitted via verified, air-gapped channels. Any request for “damage status” or “part inventory” originating from within the network should be treated as a potential breach indicator.
• Incident Response with Kinetic Awareness: Incident response (IR) plans must now include a physical security component. If a “reconnaissance-style” intrusion is detected in the morning, plant personnel must be prepared for potential kinetic strikes in the afternoon.
