Ubiquitous Technical Surveillance (UTS) is the widespread collection and analysis of data from various sources—ranging from visual and electronic devices to financial and travel records—for the purpose of connecting individuals, events, and locations.
This surveillance poses risks to government operations, business organizations, and individuals alike, threatening to compromise sensitive investigations, personal privacy, and organizational security. The surprising findings of a recent audit of FBI techniques to address UTS further heighten the need for awareness and response to the threats.
As the sophistication and reach of surveillance technologies continue to grow, understanding the nature of UTS and implementing effective Technical Surveillance Countermeasures (TSCM) is essential for safeguarding sensitive information and ensuring operational integrity. This work explores UTS and TSCM and suggests mitigation strategies to combat the threats.
Overview
Ubiquitous Technical Surveillance (UTS) refers to the pervasive collection and analysis of data including visual, electronic, financial, travel, and online for the purpose of connecting individuals, events, and locations. The significance of the threats is outlined in a recently declassified but heavily redacted DOJ/OIG audit of the FBI's response to UTS (DOJ, 2025). Based on the number of redactions, particularly from the CIA's section of the report, it is reasonable to imagine that many incidents have occurred that have not been reported to the public.
Technical Surveillance Countermeasures (TSCM) refers to specialized procedures and techniques designed to detect, locate, and neutralize unauthorized surveillance devices and eavesdropping threats. TSCM is commonly known as a "bug sweep" or "electronic counter-surveillance" and is used to protect sensitive information from being intercepted by covert listening devices, hidden cameras, or other forms of technical surveillance (REI, 2025), (Conflict International Limited, 2025).
UTS Devices, Data Sources, & Risks
Technical surveillance data collection can occur through a variety of devices and data sources including the following:
UTS is recognized as a significant and growing threat to government, business organizations, and individuals, with the potential to compromise investigations, business operations, and personal safety. When the collected technical surveillance information is in the wrong hands and used for nefarious purposes, harm can result.
UTS Threats
What are the UTS threats?
- Significance: Described as an “existential threat” by the Central Intelligence Agency (CIA) due to its ability to compromise sensitive operations and personal safety (DOJ, 2025, p.4).
Risks:
- Compromise of investigations, personnel PII, and sources (DOJ, 2025)
- Exposure of operational details
- Threats to personal and organizational security
- Corporate espionage (Pinkerton, 2022)
Real-World UTS Scenarios
The following incidents are a sample of situations involving UTS.
- Cartel Tracking via Phones and Cameras: Criminals exploited mobile phone data and city surveillance cameras to track and intimidate law enforcement and informants (DOJ, 2025, p.18).
- Organized Crime and Phone Records: Crime groups used call logs and online searches to identify informants (DOJ, 2025, p.18).
- Financial Metadata De-Anonymization: Commercial entities re-identified individuals from anonymized transaction data. Though this data is anonymized, in 2015, researchers from the Massachusetts Institute of Technology found that with the data from just four transactions, they could positively identify the cardholder 90% of the time. (DOJ, 2025, p.17).
- Travel Data Correlation: Adversaries used travel records to reveal covert meetings and operational activities (DOJ, 2025, p.1).
- Online Activity Analysis: Aggregated web and social media data to build detailed personal profiles (DOJ, 2025, p.1).
- Visual Surveillance: Use of CCTV and smart devices for real-time tracking and event reconstruction.
- Electronic Device Tracking: Exploitation of device signals and unique identifiers for location tracking.
- Combined Data Exploitation: Overlaying multiple data sources to establish “patterns of life.”
- Commercial Data Brokers: Purchase of large datasets for profiling and targeting.
- Compromised Communications: Poorly secured communications exposing sensitive activities.
UTS Response: Organizational Challenges - FBI
The FBI identified UTS as an issue impacting the Bureau. However, a recently unclassified audit of the FBI's approach to UTS by the Office of Inspector General (OIG) identified several challenges and areas for improvement in the FBI's approach (DOJ, 2025, p.4).
OIG Audit of the FBI's Efforts (DOJ, 2025)
- Red Team Analysis: Initial FBI efforts were high-level and did not fully address known vulnerabilities.
- FBI Strategic Planning: Ongoing development, but lacking clear authority and coordination.
- Training Gaps: Basic UTS training is mandatory for FBI personnel, but advanced training is limited and optional.
- Incident Response: FBI Data breaches revealed policy gaps and lack of coordinated response.
- Recommendations: The FBI needs comprehensive vulnerability documentation, strategic planning, clear authority, and expanded training.
Countermeasures & Best Practices
Combating the threats from UTS is a daunting challenge. Several steps can be taken to mitigate the threats.
Scenario-Specific Steps
Suggested General Countermeasures
- Regular training on digital hygiene and counter-surveillance
- Encryption of sensitive data and communications
- Physical security for sensitive locations and devices
- Vigilance and behavioral adaptation to signs of surveillance
- Technical Surveillance Countermeasures (REI, 2025), (Conflict International Ltd, 2025), (EyeSpySupply, 2023).
Training & Awareness (DOJ, 2025)
- Basic UTS Awareness: Should be mandatory for all FBI personnel.
- Advanced UTS Training: Recommended for high-risk FBI roles; should be expanded and resourced.
- Continuous Learning: Stay updated on emerging threats and countermeasures.
Incident Response Recommendations from the OIG Audit of the FBI (DOJ, 2025)
- FBI should establish clear lines of authority for UTS incidents.
- FBI should develop and rehearse coordinated response plans.
- FBI should regularly review and update internal controls and policies.
Summary
The growing sophistication and reach of surveillance technologies have made UTS a threat to government operations, business organizations, and individuals. Real-world incidents demonstrate how adversaries exploit mobile phone data, surveillance cameras, financial transactions, and travel records to compromise investigations, expose operational details, and threaten personal and organizational security.
The FBI, recognizing UTS as an existential threat, has faced challenges such as insufficient planning, limited training, and gaps in incident response.
Technical Surveillance Countermeasures (TSCM), including procedures like bug sweeps and electronic counter-surveillance, are tools for detecting and mitigating unauthorized surveillance devices. Best practices for mitigation include regular training, encryption, physical security, and continuous awareness of emerging threats.
Conclusion
The risks posed by UTS are immediate and evolving, with the potential to undermine investigations, compromise privacy, and threaten organizational integrity. Effective countermeasures require a combination of technical solutions, organizational policies, and training. The findings of the OIG audit of the FBI highlight the need for clear authority, coordinated response plans, and regular updates to internal controls. As surveillance technologies continue to advance, adopting a proactive and comprehensive approach to counter-surveillance is important for safeguarding information and maintaining operational security.
