Analytical Essay: Counterintelligence in an Interconnected World
In an increasingly interconnected world, the ability for peer and near-peer actors to spy grows as intel agencies are no longer limited by traditional human intelligence (HUMINT) collection. Cyber and technological fronts offer increased capabilities for adversaries to infiltrate systems, intercept communications, and exfiltrate data. But in the role of counterintelligence (CI), these systems need to complement each other and support what raw data or raw HUMINT cannot do alone. The United States Intelligence Community (USIC) must strike a balance between offensive, defensive, and strategic CI methodologies to counter the damage historically done by adversaries, prepare for digital age of spycraft, and blaze the trail for the world in setting acceptable norms for cyber CI and covert or clandestine actions.
The distinction between defensive CI and offensive CI can be broadly defined as reactive versus proactive, respectively. Defensive CI means responding to threats and identifying those who might have been targeted or exploited by external or adversarial intelligence agencies. Robert Hanssen is a case study in a long-term asset working as a double agent for both the FBI, domestically, and the Soviet and Russian GRU intelligence services abroad. Hanssen was able to evade detection by staying under the radar enough through his own counterintelligence training by the FBI. Although it was the FBI that finally apprehended Hanssen, agencies can be loath to look internally for finding compromised agents. These same competitive forces that cause hierarchical and budgetary stress mean that agencies don’t necessarily want to spend resources or act immediately on concerns raised from other external agencies (Lowenthal 2025).
Offensive CI goes on the attack attempting to turn their adversarial assets into friendly ones through coercion, deception, or force. This can be overt – in the case of Hanssen, he was given gifts and cash – or covert through the dissemination of invalid or partial intelligence. For the USSR/Russia, the gifts to Hanssen were offensive CI; for the USIC, catching Hanssen was defensive CI (Lowenthal 2025). Depending on where one stands, offensive CI’s methodology to weave distrust and deception can begin to bleed into more covert actions such as influence operations. During the COVID pandemic, the Pentagon ran a hybrid counterintelligence/covert psychological operation in the Philippines to sow doubt about the effectiveness of the Chinese Sinovac vaccine and weaken Chinese influence in the region (Bing and Schectman 2024).
Van Cleave (2007) proposes a more holistic approach to CI operations that doesn’t need a choice between offensive and defensive. Strategic CI, per Van Cleave (2007), seeks to neutralize threats before they reach the homeland rather than reacting after compromise occurs — though this proactive stance can itself blur into covert action. U.S. support for anti-Soviet fighters in Afghanistan, intended to weaken a rival intelligence service, later gave rise to the terrorist networks that would become Al Qaeda (Coll 2004).
As the world is ever-more online, Iranian and Russian social media farms are able to amplify divisive issues to ratchet up political tensions or frustrations. Iranian social media groups are able to undercut support for US-led intervention using AI music videos that further agitate US political divides (Lesser 2026). Conversely, Russia’s compromise of the Democratic National Convention’s email server and selective leaks created an entire supporting mythology in Pizzagate and later, QAnon (Rid 2020). These digital campaigns are having an outsized role in pop culture and US election cycles and leading to direct unrest of the American constituency.
China’s role, on the other hand, is largely economic. During the Cold War, the US Government was the hub of secret and classified information; but in the modern world proprietary data and critical infrastructure live with private companies who are necessarily connected to the internet. China’s ownership of critical manufacturing centers and blend of semi-private, semi-military corporate structures provide them an advantage in deniability and stealth. Chinese manufacturer Zbtlink shipped routers across the world with backdoors pre-installed (Cloud Security Alliance 2026), and Sygnia identified a related Chinese state-linked campaign, Fire Ant, compromising network infrastructure in similarly secured corporate environments (Google Cloud Threat Intelligence 2025; Sygnia Incident Response 2025). This close cooperation of private and public sector corporate espionage is an emerging hybrid threat to national security that the United States must adapt to understand and counter.
Countering these sophisticated economic and digital threats requires a steady, unified strategy, but historically, the U.S. response has often been undermined by its own defensive posture. James Angleton saw spies everywhere (Lowenthal 2025). Van Cleave (2007) describes a paranoia paradox where the more aware one is to deception, the more likely one is to be deceived. If the United States would like to combat cyber and technological threats, it needs to set aside this paranoia and seriously weigh going it alone. A digital Geneva Convention governing rules of the road for cyber operations could set up guidelines for peacetime that other nations could follow (Smith 2017). Given the United States’ wavering commitments to things like the Paris Accords or Iranian Nuclear Disarmament, it would be reasonable that adversarial nations or peers would be skeptical. The United States, however, has the opportunity to craft appropriate guidelines for restricting state-sponsored or proxy attacks on civilian infrastructure such as hospitals. This ruleset could help define the escalation ladder of what to expect in terms of proportional digital response, as well. A critique to this plan is that the United States should not tip its hand, a callback to the Nixonian “madman doctrine.” But greyzone digital wars in the modern era currently lack guardrails. Providing a path with moral conviction might be naive, but it could also be an opportunity to show the world that the USIC aims for global security.
