How Can You Defend Against Corporate Espionage in a Hyperconnected World?

Corporate espionage—also known as industrial or economic espionage—is the act of stealing sensitive business information for competitive, financial, or political advantage. While “espionage” once conjured images of spies in trench coats, modern corporate espionage can be largely digital. It includes cyber espionage, physical access, and covert surveillance campaigns targeting proprietary information, intellectual property, business strategy, merger activity, and trade secrets.

Attackers can use phishing emails, malware, supply chain compromises, and credential theft to infiltrate corporate systems. Perpetrators can include state-backed bad actors and industrial spies seeking unauthorized access to valuable data or corporate networks.

Whether corporate espionage stems from rival companies, state-sponsored groups, or insiders, the impact can be devastating, both financially and reputationally. Industrial espionage is illegal but prevalent, representing one of the most significant risks to modern enterprises.

What Motivates Corporate Espionage?

Corporate espionage is often driven by one or more of the following motives:

Competitive Advantage
Rival companies may try to access product roadmaps, pricing models, or strategic plans to gain a market edge.

Financial Gain
Bad actors can monetize stolen data on the dark web or sold to brokers, competitors, or nation-state actors.

Political Objectives
Nation-state actors may receive directives from senior leadership to target critical industries like energy, defense, and technology to bolster domestic capabilities or geopolitical influence. 

Market Manipulation
External actors can use confidential information about earnings, patents, or partnerships to manipulate stock prices.

Supply Chain Intelligence
Attackers may target vendors, partners, or suppliers to understand an organization’s ecosystem and create pressure points.

These motives make corporate espionage particularly dangerous as it’s not just about data theft; It’s about long-term strategic harm.

Common Espionage Tactics in 2025

Corporate spies don’t use a single method. Their techniques evolve rapidly and include:

Phishing & Social Engineering
Attackers can pose as executives, partners, or IT support to trick employees into revealing credentials or installing malware. This enables access to sensitive information or helps attackers gain access to systems containing confidential data.

Insider Threats
Employees, contractors, or business partners are recruited, bribed, or coerced into leaking data or installing spyware.

Supply Chain Compromise
Threat actors infiltrate software or hardware vendors to indirectly access the target company.

Credential Theft and Account Takeover
Once an attacker gains legitimate login credentials—often via phishing or data breaches—they can often gain access to a series of sensitive login sites and information.

Advanced Persistent Threats (APTs)
State-aligned groups use stealthy, targeted campaigns to maintain presence inside victim systems and exfiltrate data over time.

Surveillanceware and Remote Access Trojans (RATs)
Installed on endpoints or mobile devices to track user behavior, capture keystrokes, or activate cameras/microphones.

SecurityScorecard’s threat attribution and predictive intelligence can help keep companies and SOCs ahead of bad actors. ML-driven engines map threat actor behavior and link malware, obfuscated domains, and adversary-controlled IPs to known campaigns. 

Sectors At Risk for Corporate Espionage

Corporate espionage doesn’t affect every industry equally—although every company is vulnerable to it. Some of the most targeted sectors include:

• Technology, including AI, chip design, and telecommunications firms
• Pharmaceuticals and Biotech
• Energy and Utilities
• Aerospace
• Defense
• Manufacturing
• Industrial IoT
• Finance
• Government Contractors
• Think Tanks

If your organization operates in one of these sectors, you are likely already a target—whether you’ve been breached yet or not.

Anatomy of a Corporate Espionage Campaign

Knowing where corporate espionage actors obtain their information and how they choose to act can help security leaders predict where their organizations may be most vulnerable. Here is an example of how corporate espionage actors progress through a campaign:

Reconnaissance
The attacker gathers open-source information from employee LinkedIn profiles, press releases, GitHub repositories, and social media.

Initial Access
The bad actor uses spearphishing emails or malicious USB drops to gain a foothold. Alternatively, the attacker could exploit a vulnerable vendor system.

Establishing Persistence
The attacker installs malware or creates backdoors for repeated access, often using stolen credentials to blend in.

Privilege Escalation and Lateral Movement
The attacker moves through the environment to reach sensitive assets, often using internal tools like PowerShell.

Exfiltration
The bad actor identifies trade secrets, proprietary code, deal terms, or communications and extracts them gradually to avoid detection.

Covering Tracks
The hacker employs log tampering and encrypted tunnels to help avoid alerts.

This campaign may unfold over months or even years. Without strong monitoring and anomaly detection, it often goes unnoticed until the damage is done.

Key Cybersecurity Best Practices to Defend Against Corporate Espionage

1. Implement Zero Trust Architecture
   Adopt a “never trust, always verify” model that enforces least-privilege access, continuous authentication, and segmentation.

• Authenticate users and devices dynamically
• Use identity-based access rather than IP-based
• Enforce per-session verification for sensitive systems

2. Harden Endpoint Security
   Endpoints are the most common entry points for espionage actors.

• Deploy EDR (Endpoint Detection and Response) solutions
• Monitor for behavior anomalies (e.g., access at odd hours)
• Use application allowlisting to prevent rogue installs

3. Secure Communications and Collaboration Tools
   Espionage groups often target email, Slack, Microsoft Teams, or cloud drives.

• Encrypt emails and chat content
• Use DLP (Data Loss Prevention) policies
• Monitor external file shares and access permissions

4. Vet and Continuously Monitor Third-Party Vendors
   Vendors are prime espionage vectors.

• Use standardized questionnaires like SIG
• Continuously monitor third-party risk using platforms like SecurityScorecard
• Require vendors to use MFA, patch promptly, and disclose breaches quickly

5. Monitor for Insider Threats
   Some espionage groups recruit insiders or leverage existing disgruntled employees.

• Monitor user behavior analytics (UBA)
• Flag excessive downloads or off-hour access
• Segregate duties and restrict admin privileges

6. Protect Intellectual Property with Rights Management
   Use digital rights management (DRM) to restrict document usage.

• Limit copy/paste, printing, and sharing
• Watermark sensitive documents
• Monitor file access by user, location, and device

7. Implement Strong Credential Policies
   Many espionage campaigns exploit weak or stolen passwords.

• Enforce password complexity and rotation
• Use hardware-backed MFA (e.g., YubiKeys)
• Detect and block reused credentials exposed in breaches

8. Conduct Red Team and Tabletop Exercises
   Simulate espionage scenarios to evaluate detection and response.

• Red team exercises should focus on stealthy lateral movement
• Tabletop simulations should include legal, PR, and board response
• Lessons learned should be fed back into policy updates

Executive and Board-Level Engagement Corporate espionage is not just an IT issue—it’s a C-level and board concern. Security leaders should report on:

• Risk scores of top vendors and subsidiaries
• Open critical vulnerabilities tied to IP or M&A systems
• Credential exposure trends over time
• Espionage-related tabletop findings and readiness
