Grey Zone Cyber Operations © Neo Institute Europa

Cyber operations have become a permanent feature of international competition, blurring the boundaries between peace and conflict. For Russia, cyberspace is not a separate battlefield but an extension of state strategy, closely linked to intelligence activity, diplomatic pressure and broader geopolitical objectives. Europe’s political and economic interconnectedness has consequently made it a persistent target of Russian cyber activity.

Rather than isolated incidents, these operations form part of a broader pattern of “grey-zone” engagement aimed at remaining below the threshold of open conflict while still shaping perceptions, testing resilience and creating uncertainty across political and security systems.

Strategic doctrine: Why Russia uses cyber operations

Russia’s approach to cyber operations is best understood as part of a broader doctrine of hybrid warfare (gibridnaya voyna), where informational, psychological and technical tools are integrated into a single strategic framework. Within this model, cyber activity is not an auxiliary capability but a core instrument for shaping the strategic environment in peacetime and during conflict.

The primary objectives are multidimensional: Cyber operations enable intelligence gathering and long-term access to sensitive networks, providing visibility over political, military and industrial systems. They are also used to undermine institutional trust and amplify divisions within European states, and can indirectly support kinetic objectives by disrupting systems or degrading situational awareness during crises.

These activities are typically associated with Russian state intelligence structures, particularly the GRU, the FSB and the SVR. However, operational execution is often dispersed across a broader ecosystem of proxy actors, enabling plausible deniability while maintaining strategic coherence at the state level.

Actor Ecosystem: State, proxy groups and intelligence services

Russian cyber activity in Europe operates through a layered network of state institutions, intelligence services and proxy actors, providing flexibility and plausible deniability while complicating attribution and response.

At the core of this system are Russia’s principal intelligence and security agencies. The GRU is widely associated with offensive cyber operations linked to military and geopolitical objectives. The FSB focuses on domestic security but is also involved in counterintelligence and external cyber activity. The SVR concentrates on strategic intelligence collection and long-term access to foreign political and diplomatic networks.

Alongside these formal structures exists a broader ecosystem of cybercriminal groups and contractor-style operators. These actors may operate with varying degrees of state direction, ranging from direct tasking to informal alignment of interests. In some cases, their activities blur the line between financially motivated cybercrime and politically motivated operations, particularly when targeting European institutions or critical infrastructure.

This model provides Russia with flexibility and plausible deniability, while complicating European efforts to distinguish state-backed operations from cybercrime.

Methods of operation: How cyber influence and intrusion happens

Russian cyber operations in Europe rely on stealth, persistence and psychological impact, often exploiting weaknesses in infrastructure, human behavior and coordination rather than advanced technical innovation. Effectiveness lies more in timing and sustained access than in complexity.

Common methods include spear-phishing and credential theft to gain initial access to government institutions, political organisations, media outlets and private companies. Once inside, operators prioritise persistence and intelligence collection over disruption, enabling long-term monitoring of communications and internal systems. Supply chain compromise is also a key vector, exploiting third-party providers to indirectly access broader networks and turning single vulnerabilities into wider systemic exposure.

Cyber activity often overlaps with information operations, where stolen data is selectively leaked to shape narratives, damage reputations or undermine trust in public institutions. Disruptive actions such as DDoS attacks, defacements and temporary service outages are also used during periods of international tension for signalling and short-term disruption.

Targeting Europe: Strategic objectives and sectoral exposure

Russian cyber activity against Europe is neither random nor opportunistic. Target selection consistently reflects broader strategic priorities and is designed to maximise intelligence value, leverage and political pressure. Europe’s interconnected institutions and digital dependence make it particularly suitable for sustained cyber operations.

Government institutions and diplomatic networks remain primary targets due to their intelligence value, providing strategic insight through access to internal communications and policy processes. This was illustrated by the SolarWinds compromise, attributed to actors linked to the SVR, which enabled long-term access to government networks through supply chain infiltration. Russian cyber operations also frequently align with international crises. Following the 2022 war in Ukraine, European governments experienced increased DDoS attacks and intrusion attempts, particularly in states supporting sanctions or military aid, demonstrating cyber activity’s role as a tool of strategic signalling.

The risks, however, extend beyond government institutions. The 2017 NotPetya malware outbreak, initially directed at Ukraine, rapidly spread across Europe, severely affecting multinational companies, logistics operators and industrial systems. NotPetya demonstrated how cyber operations linked to regional geopolitical objectives can generate large-scale spillover effects across Europe’s interconnected digital and economic infrastructure.

Political environments are also recurrent targets, particularly during elections or periods of polarisation. The 2017 MacronLeaks incident in France demonstrated how stolen materials can be strategically released to generate confusion and undermine public trust, even when direct electoral impact remains limited. The objective is less to alter outcomes than to erode confidence and amplify uncertainty.

Critical infrastructure represents another key area of focus. Energy systems, transport networks and telecommunications infrastructure are especially sensitive due to their role in national resilience. Earlier attacks on Ukraine’s power grid, widely linked to the GRU, showed how cyber operations can extend beyond espionage into functional disruption, reinforcing European concerns about spillover risks and hybrid escalation.

The media and information ecosystem also occupies a central place in Russian cyber strategy. Journalists, broadcasters and digital platforms may be targeted not only for espionage purposes but also as channels through which narratives can be manipulated, amplified or destabilised. Cyber operations in this domain often intersect with disinformation efforts, creating a feedback loop between technical compromise and informational influence.

Defence-related industries, research institutions and entities linked to NATO have similarly become high-value targets. The objective in these cases extends beyond intelligence collection, encompassing the broader goal of monitoring European defense coordination and technological capabilities.

Russian cyber campaigns are not aimed at decisive outcomes, but rather at sustaining pressure, exploiting uncertainty and gradually eroding institutional resilience through a blend of espionage, disruption and psychological influence.

Strategic impact on Europe

The impact of Russian cyber activity on Europe extends beyond individual incidents, with cumulative effects contributing to strategic uncertainty, institutional pressure and political fragmentation. Repeated targeting of public institutions erodes trust in governments’ ability to protect critical infrastructure, while the perception of vulnerability itself becomes strategically valuable.

These operations also impose a growing defensive burden, as states and companies must continuously invest in cybersecurity and response capabilities, creating an asymmetric dynamic where low-cost attacks drive sustained expenditure. When combined with disinformation or data leaks, they further amplify political polarisation by increasing confusion and distrust rather than promoting a single narrative.

At the strategic level, the cross-border nature of cyber threats complicates coordination within the EU and NATO, particularly in attribution and joint response.

European response and limitations

Europe’s response to Russian cyber activity has evolved over the past decade, shifting from fragmented national approaches toward more coordinated EU and NATO frameworks. However, progress remains uneven, and structural limitations still constrain the effectiveness of collective defense.

At the policy level, the European Union has strengthened its cybersecurity architecture through regulatory and operational instruments, including the expansion of incident reporting requirements, resilience standards and critical infrastructure protections. Frameworks such as NIS2 have pushed member states toward higher baseline security expectations and more formalised cooperation between public and private sectors. At the same time, national Computer Emergency Response Teams (CERTs) and intelligence agencies have improved information sharing, particularly in response to large-scale incidents.

Parallel to this; NATO has increasingly recognised cyberspace as an operational domain, integrating cyber defense considerations into collective security planning. This includes enhanced coordination mechanisms and the development of rapid response capabilities for cyber incidents affecting allied infrastructure.

Despite these advancements, key limitations remain: Attribution is difficult to translate into a timely, unified political response across states, weakening deterrence. Offensive cyber operations remain low-cost and scalable, while defence requires sustained investment and coordination. Adding to this, governance fragmentation slows decision-making during fast-moving incidents. Overall, despite progress in resilience, Russian cyber activity continues to expose persistent gaps in coordination, attribution and deterrence.

A new arena

Russian cyber activity in Europe reflects sustained strategic pressure rather than isolated incidents. Across espionage, disruption and information operations, cyberspace is used as a continuous instrument of statecraft tied to broader international objectives. The cumulative effect is increased uncertainty, higher defensive costs and persistent strain on resilience, as operations aim to maintain pressure and exploit Europe’s structural openness.

For Europe, this reinforces a basic reality: Cyberspace is a permanent arena of competition, where security is dynamic, contested and never fully settled.
