Counter-surveillance, IT forensics & court-admissible expert opinions
Your contact for professional counter-surveillance and digital eavesdropping protection. IT forensics and legally admissible evidence preservation
Confidential information forms the basis of virtually every private, business, and governmental decision. Trade secrets, development projects, contract negotiations, sensitive communication data, and personal information represent significant economic and personal value. If this information falls into the hands of unauthorized third parties through industrial espionage, cyberattacks, data theft, or technical surveillance measures, the consequences can be severe.
Modern attacks are rarely carried out solely through traditional eavesdropping devices. Much more often, physical and digital methods are intertwined. While meeting rooms are being monitored for hidden surveillance equipment, smartphones may simultaneously be infected with spyware or corporate networks may be compromised. Therefore, simple counter-surveillance measures or isolated IT investigations are often no longer sufficient.
LB Forensics pursues a holistic investigative approach. We combine professional counter-surveillance, technical eavesdropping protection, IT forensics, mobile forensics, digital evidence preservation, and expert reports into a comprehensive security service. This allows our clients to receive all services from a single source – from technical security checks and forensic analysis of digital devices to legally admissible documentation of the investigation results.
Our services are aimed at companies, medium-sized businesses, corporations, law firms, tax advisors, auditors, authorities, public institutions and private individuals throughout Germany.
A particular advantage for our clients is that we do not charge any travel costs nationwide. Regardless of whether the work location is in Hamburg, Berlin, Munich, Frankfurt, StuttgartIf the location is Cologne or another region of Germany, there are no additional travel costs.
Why counter-surveillance and IT forensics are inextricably linked today
Technological advancements have changed the way information is spied on and data is stolen. While in the past the focus was on classic wireless bugs or wired eavesdropping technology, perpetrators today use far more complex methods.
Besides hidden microphones, other methods used include digital surveillance systems, Wi-Fi components, mobile phone modules, IP cameras, GPS trackers, cloud services, malware, and specially developed spyware. Smartphones or computers themselves are often used as unnoticed surveillance tools.
Many security incidents begin with a seemingly simple suspicion.
Confidential conversations are suddenly revealed to third parties. Competitors have access to internal information. Business partners know details of planned projects. Employees report unusual activity on their smartphones or computers. Vehicles appear to be monitored, or sensitive documents are leaked.
In practice, it is repeatedly shown that technical and digital attacks are interconnected.
A suspected eavesdropping attack may later turn out to be professional spyware on multiple mobile phones.
A suspected hacking attack may be due to internal data theft.
A compromised notebook provides evidence of industrial espionage, even though originally only a standard bug sweep was commissioned.
That's precisely why we take a comprehensive approach to every situation. Our specialists don't just analyze individual devices or rooms, but investigate the entire technical and digital security incident.
This interdisciplinary approach often yields insights that would have remained hidden in an isolated investigation.
Professional counter-surveillance and technical eavesdropping protection
The term counter-surveillance refers to the professional technical inspection of premises, vehicles or objects for hidden surveillance and listening devices.
The requirements for modern counter-surveillance have changed considerably in recent years. Besides traditional radio bugs, numerous digital systems now exist that can capture and transmit confidential information in a variety of ways.
Our specialists conduct technical security checks in the following areas, among others:
- Company
- Executive offices
- meeting rooms
- Conference centers
- law firms
- Certified Tax Advisor
- surgeries
- Authorities
- Research institutions
- Production plants
- Private apartments
- building site
- holiday properties
- Hotel Rooms
- Motor vehicles
- Campers & RVs to Rent
- Yachts
Depending on the circumstances, different investigation procedures are used.
This includes, among other things, visual inspections, technical functional tests, spectrum analyses, high-frequency measurements, investigations of wired communication paths, electromagnetic measurement procedures, and the analysis of suspicious electronic components.
The aim of every investigation is to identify potential security risks and to document all investigation steps in a traceable manner.
Eavesdropping protection for companies
Today, companies are among the most frequent targets of economically motivated information gathering.
Trade secrets, tenders, pricing strategies, development data or contract negotiations often have considerable economic value.
A successful information leak can cause losses in the millions and permanently impair competitiveness.
Our services in the field of eavesdropping protection for companies include, among other things:
- Technical security checks before important meetings
- Review of executive floors
- Examination of conference rooms
- Security review of sensitive development areas
- Investigation following employee changes
- Preventive measures against economic espionage
- Sicherheitsberatung
- Investigation of specific suspected cases
Our work is not limited solely to finding potential listening devices.
We also analyze organizational weaknesses and technical attack vectors and provide recommendations for improving information security.
Detect economic espionage early
Industrial espionage often begins long before a company even notices that information has leaked.
Often, only minor irregularities are noticed at first. Competitors react unusually quickly to new developments. Offers resemble internal calculations. Customers receive confidential information, or previously secret projects become public.
Our specialists assist companies in investigating potential cases of industrial espionage.
Here we consider all conceivable information pathways.
This includes both classic technical surveillance measures and digital attack methods, insider crimes, data theft or manipulation of IT systems.
By combining counter-surveillance and IT forensics, many relationships can be assessed much more comprehensively than through an isolated investigation of individual areas.
IT forensics – professionally securing digital evidence
Digital data plays a central role in almost every investigative procedure today.
Computers, smartphones, tablets, servers or cloud systems store a variety of information that can allow conclusions to be drawn about user activities, communication histories or technical events.
The task of IT forensics is to secure this information in a traceable manner, to evaluate it technically, and to document it in a structured way.
Our specialists analyze, among other things:
- Desktop computer
- Notebooks
- Server & Hosting
- Network storage
- external storage devices
- SSDs
- USB storage devices
- Virtual systems
- Cloud data
- Email systems
The focus of every investigation is the digital preservation of evidence.
Depending on the question at hand, we reconstruct technical processes, analyze user activities, examine file systems, evaluate log files, and document all investigation steps in a traceable manner.
Typical questions from our clients are:
- Investigate data theft
- Investigate hacker attack
- Trace data leaks
- Solving insider trading
- Manipulation of digital documents
- Data recovery
- Analysis of suspicious activities
- Investigation of compromised systems
- Reconstruction of technical incidents
Our investigations are conducted exclusively in accordance with the specific questions posed by the client.
Mobile forensics – professional examination of smartphones and tablets
In many investigations, the most important digital evidence is no longer found on traditional computers, but on mobile devices. Smartphones and tablets store a wealth of sensitive information daily, including communication histories, location data, calendar information, documents, images, videos, notes, and data from a wide variety of applications.
Especially in connection with economic espionage, data theft, fraud offenses or the suspicion of unauthorized surveillance, mobile devices often provide crucial clues.
Our mobile forensics specialists analyze, among other things:
- Apple iPhone
- apple ipad
- Android smartphones
- Android tablets
- messenger services
- Communication processes
- Location information
- Photos and videos
- Documents
- Cloud synchronizations
- App data
- Browser data
- Fuses
- User activities
Depending on the specific question, we investigate, for example, whether data has been deleted, whether manipulation has occurred, or whether there are indications of unauthorized access. Likewise, information about synchronization processes, account links, or communication patterns can be analyzed, insofar as technically possible.
Our mobile forensic investigations serve both the technical clarification and the legally admissible documentation of digital facts.
Detect spyware and uncover digital surveillance
Not every surveillance attack is carried out using classic eavesdropping techniques.
In recent years, the number of professional spyware and stalkerware attacks has increased significantly. These attacks deliberately compromise smartphones or computers to eavesdrop on conversations, read messages, transmit locations, or exfiltrate confidential information.
Those affected often remain unaware of such surveillance for a long time.
Our specialists examine end devices for possible indications of, among other things:
- spyware
- stalkerware
- malicious software
- Trojans
- Remote access software
- Manipulated applications
- Unusual system changes
- Unusual permissions
- Suspicious network communication
- Technical information
- Compromises
Not every unusual occurrence necessarily constitutes an attack. The aim of our investigation is therefore an objective and verifiable technical assessment of the respective situation.
Data theft and digital evidence preservation
The unauthorized leakage of confidential data is one of the biggest risks facing modern companies.
Whether customer data, technical drawings, development documents, calculations or internal communication – digital information often has considerable economic value.
Our IT forensic investigations help companies to clarify potential data thefts and to secure digital traces in a traceable manner.
Depending on the question being asked, this can involve evaluating, for example, user activities, file accesses, storage media, communication data or technical protocols.
Digital evidence preservation forms the basis for internal investigations as well as possible civil or criminal proceedings.
Expert opinions and technical statements
Technical investigations only become truly beneficial when the findings are documented in a comprehensible manner.
Therefore, we prepare expert reports and technical statements to clearly explain complex technical issues.
Our expert reports can be prepared for various purposes, including:
- Private appraisal
- Court opinion
- Preservation of evidence
- Insurance matters
- Internal investigations
- Employment law proceedings
- Civil proceedings
- Criminal proceedings
The documentation is comprehensible, structured, and geared towards the specific technical questions of the client.
Certified expert competence
A key component of our work is the expert evaluation of technical investigation results.
The management of the LB Group holds certification as experts according to DIN EN ISO/IEC 17024 in the relevant fields. This standard describes internationally recognized requirements for the certification of individuals and creates a uniform basis for proven professional competence.
The certification is generally recognized beyond Germany's borders. However, the legal significance of an expert opinion in any given case always depends on the respective legal and procedural requirements of the country and the responsible authority.
Our clients benefit from a comprehensible technical assessment of complex issues as well as understandable documentation of the investigation results.
Why the combination of counter-surveillance, IT forensics and expert assessments is crucial
Many security incidents today can no longer be clearly attributed to a single field of expertise.
A company initially suspects a classic wiretapping operation.
However, the technical security check reveals no evidence of an active listening device.
In contrast, the subsequent IT forensic investigation will identify compromised end devices, suspicious user activity, or indications of data leakage.
Similarly, a suspected hacker attack may actually be due to internal information leaks or organizational weaknesses.
The combination of:
- Counter-surveillance
- Eavesdropping protection
- IT forensics
- Mobile forensics
- digital evidence preservation
- Data protection
- expert assessment and appraisal
It enables a comprehensive analysis of complex security incidents and reduces interfaces between different service providers.
This allows our clients to receive all services from a single source – from the initial technical assessment to the final expert documentation.
