In 2025, insider threats are more sophisticated than ever. They can stem from malicious intent, economic pressures, geopolitical influence, or even accidental mistakes by well-meaning employees.
With hybrid work security, cloud adoption, and digital transformation, traditional security measures are no longer enough to protect sensitive data and critical assets. This report highlights the five most critical insider threat trends of 2025, illustrated with real-world insider threat examples, and offers actionable strategies for insider threat prevention.
What is An Insider Threat?
Insiders are not just employees who act maliciously. Insider threats include any person with legitimate access—employees, contractors, managed-service engineers, or partners—whose actions, intentional or accidental, can put your company’s data or systems at risk. Their authorized access makes detection harder, as activity often appears normal. That’s why effective insider threat management is essential to identify risks that blend into day-to-day operations.
The key question for most of company is not just “who did this,” but “how can normal credentials become a strategic risk?”

5 Insider Threat Trends Deep Dive
In 2025, five key insider threat trends are geopolitical influence, AI misuse, supply chain security vulnerabilities, hybrid work security risks, and economic pressure. These trends are driving increasingly sophisticated internal risks that require proactive detection and insider threat management.
Trend 1: Geopolitically Driven Advanced Insider Threats
One major trend in 2025 is geopolitically driven insider activity. While many assume insiders act mainly for money, advanced insiders—such as privileged administrators, developers, or engineers—may be influenced, coerced, or recruited by external actors with geopolitical motives.
Unlike opportunistic insiders, they are patient and technically skilled, embedding stealthy persistence mechanisms, creating hidden access pathways, or implanting dormant logic designed to activate months later. They often target intellectual property, defense contracts, or sensitive infrastructure data. By blending their activity into normal administrative tasks, they can quietly exfiltrate strategic assets or manipulate systems without triggering standard alerts, making detection extremely difficult.
Potential Impact:
- Large-scale operational outages and service disruption
- Theft of high-value IP or sensitive national/industry information
- Regulatory penalties and complex cross-jurisdiction investigations
- Long-term reputational damage and stakeholder distrust
⚠️ Real Insider Threat Example: Tesla Engineer Accused of Stealing “Dojo” Supercomputer Secrets
In 2021, Tesla filed a lawsuit against software engineer Alexander Yatskov. He was accused of copying a significant amount of confidential information related to Tesla’s “Dojo” supercomputer project onto personal devices. Investigations suggested that some of the information may have been shared with an unidentified foreign entity. In April 2023, the case was settled confidentially, with Yatskov agreeing to pay an undisclosed amount.
This case is considered a notable example of a sophisticated insider threat, potentially influenced by external factors and linked to international competition in artificial intelligence and autonomous driving technologies.

Trend 2: AI-Powered Insider Attacks
Another key development is the misuse of AI. In 2025, AI isn’t just a defender’s tool—it has become a powerful enabler for insiders with malicious intent. Even employees with little to no technical background can leverage generative AI assistants to craft custom data-exfiltration scripts, automate credential harvesting, or fine-tune phishing campaigns that appear tailored and legitimate. AI lowers the barrier to entry, turning what once required advanced skills into point-and-click operations.
At the same time, deepfake technology allows insiders to impersonate executives, manipulate voice or video communications, and push fraudulent transactions with unprecedented credibility. These attacks often unfold in “low-and-slow” patterns—small file movements, delayed commands, or workflow-consistent actions—that blend seamlessly into normal operations. Because they mimic real user behavior, such AI-driven tactics frequently bypass threshold-based SIEM alerts and leave defenders struggling to distinguish genuine activity from malicious intent.
Potential Impact:
- Stealthy, automated exfiltration that evades detection for weeks
- Internal fraud via AI-generated instructions or synthetic identities
- Accelerated IP loss and competitive disadvantage
- Compliance exposure and potentially large fines
⚠️Real Insider Threat Example: Internal Fraud Using AI Tools
In early 2024, an employee at a multinational company in Hong Kong was tricked into transferring HKD 200 million (about USD 25.6 million). Scammers used deepfake technology to impersonate the company’s CFO and senior executives during a video meeting, instructing the employee to make multiple transfers.
While the attackers were external, this case highlights how easily a malicious insider could misuse AI tools to fabricate executive instructions, enabling internal fraud or sabotage.
Trend 3: Supply Chain as an Insider Threat Vector
A growing concern for organizations is supply chain exploitation. Vendors, contractors, and cloud service providers hold privileged access that can be abused or compromised, creating insider-like pathways into sensitive systems.
When third-party credentials are compromised, attackers gain what appears to be legitimate, “insider” access. From there, they can move laterally into sensitive environments without triggering traditional defenses. The challenge is compounded by the fact that third parties vary widely in their security maturity: some enforce strong controls and monitoring, while others rely on weak authentication or outdated practices.
Potential Impact:
- Unauthorized third-party access to critical systems
- Loss of proprietary designs, product plans, or BOM integrity
- Production delays and operational downtime
- Contractual liability and regulatory scrutiny
⚠️Real Insider Threat Example: SolarWinds Supply Chain Attack
In 2020, the widely used IT management software SolarWinds Orion was compromised with malicious code. Attackers, believed to be state-sponsored, inserted a backdoor into official software updates. Around 18,000 organizations worldwide—including U.S. federal agencies like the Treasury and Commerce Departments—unintentionally exposed their internal networks when installing these “legitimate” updates.
This case illustrates how insider threats can be delivered through trusted vendors, showing the risks of supply chain attacks even without direct insider involvement.
Trend 4: Accidental Insider Threats in Hybrid Work Environments
An often-overlooked risk comes from accidental insider threats in hybrid work. Many incidents stem not from malice, but from negligence, misconfigurations, or lack of cyber awareness in remote setups.
In hybrid work environment, employees often rely on personal devices, unsecured home Wi-Fi, or even public networks, leaving gaps traditional security tools struggle to cover. Typical errors include storing sensitive data in personal cloud accounts, sharing confidential files through unencrypted email, or using unauthorized collaboration apps. While each act may appear harmless in isolation, the cumulative effect can expose critical assets, trigger compliance issues, and erode business continuity—making hybrid work a prime driver of unintentional insider risk in 2025.
Potential Impact:
- Unintentional exposure of employee or customer data
- Fines for cloud misconfiguration or data-protection violations
- Operational friction from remediation and loss of trust
- Increased attacker opportunities via leaked credentials or artifacts
⚠️Real Insider Threat Example: Twitter Source Code Leak
In March 2023, portions of Twitter’s (now X) source code were leaked on the code hosting platform GitHub. The code was reportedly posted by a user named “FreeSpeechEnthusiast” and remained publicly accessible for several months. While the exact cause of the leak has not been fully disclosed, security experts widely attribute it to the company’s large-scale layoffs and the challenges of managing remote work environments.
Amid personnel changes and inconsistent remote access controls, current or former employees may inadvertently or negligently make repositories containing sensitive code publicly accessible. This incident highlights the significant risk of data exposure due to misconfigurations or oversight, especially in non-traditional or hybrid work settings.
Trend 5: Economic Pressure and Opportunistic Data Theft
The final insider threat trend is opportunistic data theft driven by financial stress. In 2025, financial stress has become a powerful driver of insider risk. Employees under personal or economic pressure may attempt to monetize the information they can reach most easily—client lists, pricing models, proprietary designs, or snippets of source code. These actions rarely require advanced technical skill, but they are intentional and calculated.
To stay under the radar, individuals often move gradually, exporting small batches of data, generating routine-looking reports, or accessing files outside normal hours. While each action may seem insignificant in isolation, together they can erode competitive advantage, disrupt operations, and create lasting exposure for the organization.
Potential Impact:
- Loss of customer lists and sales pipeline advantage
- Short-term revenue loss and long-term customer churn
- Regulatory exposure and reputational damage
- Internal morale and culture erosion
⚠️ Real Insider Threat Example: GE Engineer Steals Trade Secrets Before Jumping to Competitor
In 2020, Jean Patrice Delia, an engineer at General Electric (GE) in the U.S., admitted to stealing trade secrets worth tens of millions of dollars. Delia had worked at GE for eight years, developing advanced turbine blade technology. While negotiating his departure and preparing to join a competitor, he used his position to send over 8,000 sensitive files—including design models, engineering drawings, and material data—to his personal email.
His motivation was clear: to leverage the stolen technology for a higher position and financial gain at his new employer. This case serves as a typical example of opportunistic data theft driven by personal career advancement and economic incentives.
