Introduction: The Silent War in Cyberspace
In an era where digital battles are waged daily, the world’s leading powers are sharpening their tools of deterrence—not with missiles or tanks, but with sanctions. Yet a new report from the Royal United Services Institute (RUSI) reveals a striking truth: cyber-related sanctions rarely cripple hacker groups outright. Instead, they corrode their networks from within, “toxifying” the environment that sustains them. The research, published on October 28, builds upon the first meeting of the RUSI Cyber Sanctions Taskforce, bringing together officials and experts from the UK, US, and EU to examine the hidden influence of financial restrictions in the realm of cyber conflict.
Sanctions as a Strategic Weapon
According to the RUSI report, sanctions have become an essential component of cyber deterrence strategies across governments. However, they are far from a magic bullet. Alone, they cannot completely stop cyberattacks or espionage operations. What they can do is complicate the lives of threat actors, pushing underground networks to distance themselves from sanctioned individuals or organizations. This forced isolation doesn’t always stop attacks—but it makes them more expensive, riskier, and harder to execute.
The report introduces the idea of “toxification,” a process where sanctions infect the credibility and utility of a cybercriminal network. When financial institutions, exchanges, or service providers fear being caught supporting sanctioned actors, they withdraw, severing vital lifelines. One participant at the Taskforce described this phenomenon as turning cyber operations into “toxic assets”—a label no one wants to touch.
RUSI also found that cyber sanctions yield the strongest results when combined with broader diplomatic, intelligence, and law enforcement efforts. In short, sanctions work best as part of a wider web of pressure, rather than as a solitary act of punishment.
The United States: Sanctions with Precision and Power
The United States continues to lead in cyber sanction enforcement. Its legal foundation, Executive Order 13694 (established in 2015), allows Washington to target individuals and entities involved in significant cyber threats. This includes state actors, military hackers, and criminal organizations.
Unlike many other nations, the US strategy focuses on naming individuals—the real people behind the attacks. This approach is powerful because identities are persistent, unlike cyber groups that can simply rebrand or reorganize. When a hacker’s name is tied to sanctions, it haunts them across borders, cutting off financial access and limiting travel.
Additionally, US sanctions are rarely deployed alone. They are typically paired with indictments, diplomatic warnings, and public technical advisories. This multi-pronged pressure not only deters cyber aggression but also signals strength and coordination among American agencies. The combination of naming, shaming, and punishing has proven to be one of the most effective cyber deterrence tools in the world today.
The European Union: Strong Diplomacy, Weak Execution
The EU, by contrast, faces structural and political challenges in executing its cyber sanction regime. Introduced in 2019 as part of its cyber diplomacy framework, the EU’s system allows it to freeze assets and impose travel bans on individuals responsible for attacks against member states.
However, since its inception, only 17 individuals and 4 entities have been sanctioned—an underwhelming figure for such a vast bloc. The reason lies in bureaucracy: every sanction requires unanimous agreement from all 27 member states. This demand for consensus has diluted many sanction efforts, with the final decisions often reflecting the lowest common denominator.
Moreover, limited intelligence sharing among EU nations restricts how much evidence can be disclosed, resulting in weak public justification. This lack of transparency and data on impact makes it difficult to measure effectiveness.
Still, there are signs of progress. France publicly attributed attacks to Russia’s GRU in April 2025, and Czechia blamed China’s APT31 group in May 2025—major steps toward collective attribution. This new openness may pave the way for more robust and united EU cyber responses in the future.
The United Kingdom: Building Alliances and Coordination
Since leaving the EU, the UK has developed its own cyber sanctions regime (established in 2020), designed to align closely with US policies and coordinate with international and private sector partners. The British approach places emphasis on detail and collaboration, often including richer attributions that help global companies and allies understand the context behind sanctions.
However, the UK faces its own hurdles. Pairing sanctions with criminal indictments has proven difficult due to the high legal standards required and the low chance of capturing foreign hackers. Unlike the US, which frequently uses indictments as part of its strategy, the UK focuses more on using sanctions for signaling, disruption, and diplomatic purposes rather than direct law enforcement.
This reflects a pragmatic reality: while sanctions can hinder operations, they rarely bring perpetrators to justice. Their true power lies in communication—sending a message of resolve, deterrence, and collective defense.
Strategic Recommendations from RUSI
The RUSI report concludes with a series of policy recommendations aimed at enhancing the impact of cyber sanctions worldwide:
Clarify strategic intent: Governments should define what success looks like when imposing sanctions—whether it’s deterrence, punishment, or behavioral change.
Adopt cross-domain coordination: Pairing sanctions with diplomatic actions, law enforcement, and covert measures amplifies their effectiveness.
Target enablers, not just hackers: Disrupting cryptocurrency exchanges, infrastructure suppliers, and intermediaries creates broader operational chaos for cybercriminals.
Increase transparency: Publish more data on frozen assets, operational disruptions, and behavioral impacts to improve public accountability and policy refinement.
These recommendations reflect a key insight: sanctions should not be seen as a silver bullet, but as one instrument within a symphony of cyber defense tools.
What Undercode Say:
Sanctions alone are rarely decisive in cyber warfare—but they are corrosive in ways that statistics often overlook. The RUSI report highlights a psychological and economic dimension often ignored by policymakers: when a hacker network becomes “toxic,” its partners abandon it out of self-preservation. This forced isolation can be as damaging as a direct takedown.
From an analytical standpoint, the US approach demonstrates a matured strategy of precision deterrence. By targeting individuals and layering sanctions with criminal and diplomatic actions, Washington transforms punishment into pressure. Each sanction becomes a thread in a much larger narrative—one that intertwines legality, reputation, and global influence.
The EU, on the other hand, remains bound by political inertia. While its diplomatic reach is vast, operational execution lags. The requirement for unanimity weakens its agility, making the bloc’s cyber responses more symbolic than strategic. Yet, the growing willingness of countries like France and Czechia to publicly attribute attacks signals a potential shift toward a bolder Europe, one more ready to confront cyber aggressors directly.
For the UK, sanctions represent more than punishment—they are a statement of coordination. By synchronizing with allies and offering detailed public attributions, the UK strengthens the credibility of its cyber deterrence while cultivating trust among private partners.
In essence, sanctions are not just economic measures—they are instruments of narrative warfare. They expose, isolate, and stigmatize cyber actors. They reshape ecosystems where anonymity once thrived. The true value lies not in immediate disruption but in the long-term erosion of trust within hacker economies.
If properly aligned with diplomacy, law enforcement, and intelligence, cyber sanctions could evolve from being symbolic gestures into operationally disruptive tools—ones that drain adversaries of legitimacy, resources, and networks of support.
