Digital Forensics in Greece services are increasingly important in cases where computers, smartphones, storage devices and other digital systems may contain information relevant to a private, corporate or legal investigation.
At Nikos Pelekasis & Associates, we provide professional digital investigation and forensic examination services for individuals, businesses and legal professionals in Athens and throughout Greece.
Digital evidence can reveal valuable information about events, communications, files, user activity and the use of electronic devices. However, identifying and analysing this information requires appropriate methodology and careful handling of the available data.
Our objective is to identify, preserve and analyse relevant digital information while maintaining the integrity and confidentiality of the investigation.
What Is Digital Forensics?
Digital forensics is the systematic examination and analysis of digital devices and data in order to identify information that may be relevant to an investigation.
Depending on the circumstances, digital evidence may exist on:
- Desktop and laptop computers
- Smartphones and tablets
- Hard drives and SSDs
- USB drives and memory cards
- External storage devices
- Email and digital files
- Available system records and logs
- Other electronic devices and storage media
A forensic examination is different from simply opening a device and searching through its files.
The purpose is to conduct a structured investigation of the available digital information and identify findings relevant to the specific case.
Digital Forensic Examination of Computers
Computers can contain significant information concerning user activity, documents, communications and files.
Depending on the device, available data and scope of the investigation, examination may involve analysis of:
- Files and folders
- Documents and images
- Available browsing information
- System information
- User activity
- File metadata
- Storage media
- Deleted or recoverable information
- Other relevant digital traces
- Social Media Investigations
The investigation is focused on the specific questions that need to be answered rather than unnecessarily examining unrelated personal information.
Mobile Phone Forensics
Smartphones have become one of the most important potential sources of digital evidence.
Modern mobile devices can contain large amounts of information associated with applications, communications, photographs, documents and user activity.
Where lawful access to the device and data is available, a forensic examination may help identify information relevant to the investigation.
Depending on the circumstances, this may include analysis of:
- Available files and documents
- Photographs and videos
- Device information
- Application-related information
- Available communication records
- Stored data
- Relevant timestamps and metadata
- Other digital traces connected with the investigation
The information that can actually be obtained depends on the device, operating system, security configuration, condition of the data and level of authorised access available.
Electronic Evidence in Private Investigations
Digital evidence can play an important role in many types of private investigation.
A digital forensic examination may support cases involving:
- Fraud
- Theft
- Internal corporate investigations
- Information leaks
- Online threats or harassment
- Disputes involving electronic communications
- Suspicious computer activity
- Unauthorised use of digital devices
- Data-related incidents
- Other private or corporate investigations
Every case is different. Before an examination begins, the objective should be clearly defined so that the investigation focuses on information relevant to the matter being examined.
Data Recovery and Deleted Information
Deleting a file does not always mean that the information has immediately and permanently disappeared from a digital device.
Depending on the storage technology, device condition and subsequent use of the system, some deleted information may potentially remain recoverable.
Digital forensic techniques may therefore assist in identifying or recovering information that is no longer normally visible to the user.
This can include, depending on the circumstances:
- Deleted files
- Documents
- Photographs
- Videos
- Other recoverable digital information
However, data recovery is never guaranteed.
Modern encryption, secure deletion, physical damage, storage technology and continued use of a device can significantly affect whether information remains recoverable.
Digital Evidence and Metadata Analysis
A file can contain more information than what is immediately visible when it is opened.
Metadata can sometimes provide useful technical information concerning a digital file, such as dates, characteristics or other attributes associated with its creation or modification.
When relevant to an investigation, metadata analysis can help establish context and support other findings.
However, metadata should always be evaluated carefully and together with the wider circumstances of the case rather than treated as conclusive evidence on its own.
Investigation of Suspicious Files and Digital Activity
In some cases, the objective is not to recover deleted information but to understand unusual or suspicious activity on a computer or device.
This may involve examination for digital traces associated with:
- Unexpected files
- Unusual software
- Suspicious applications
- Changes to system configuration
- Unauthorised access concerns
- Unexpected network activity
- Potential monitoring or surveillance software
Where appropriate, digital forensic examination can be combined with broader technical investigation to obtain a more complete understanding of the device and its activity.
Spyware and Suspicious Software Investigation
Concerns about spyware or unauthorised monitoring require careful technical assessment.
Unusual battery consumption, unexpected network traffic or unfamiliar applications do not automatically prove that a device has been compromised.
A professional examination seeks to identify technical evidence rather than relying solely on symptoms or assumptions.
Depending on the case, examination may include analysis of installed applications, system behaviour, available records and network-related information.
Where network investigation is relevant, specialised analysis tools may also be used to examine communications and identify activity requiring further investigation.
Digital Forensics and TSCM Investigations
Digital forensic investigation and Technical Surveillance Counter-Measures (TSCM) can complement each other in certain cases.
A TSCM inspection focuses primarily on identifying potential technical surveillance threats within a physical environment, such as hidden electronic devices, transmitters or tracking equipment.
Digital forensics, on the other hand, focuses on information and activity associated with computers, smartphones and other digital systems.
When a case involves both physical and digital surveillance concerns, combining these investigative disciplines can provide a more comprehensive technical assessment.
Corporate Digital Forensics
Businesses increasingly depend on digital systems for communications, financial information, intellectual property and confidential records.
When a potential internal incident occurs, digital evidence may help establish what happened and determine whether further investigation is necessary.
Corporate digital forensic services may assist in cases involving:
- Suspected employee misconduct
- Internal fraud
- Unauthorised access
- Theft of company information
- Confidential information leaks
- Misuse of corporate devices
- Suspicious digital activity
- Other internal investigations
The scope of the examination should be clearly defined and conducted with appropriate authorisation and respect for applicable privacy and employment legislation.
Preservation of Digital Evidence
The way a digital device is handled can affect the information it contains.
Unnecessary use of a computer or smartphone after an incident may alter files, timestamps or other digital information.
For this reason, when electronic evidence may be important, it is generally advisable to avoid unnecessary changes to the device until the appropriate course of action has been determined.
Digital forensic methodology aims to preserve relevant information and maintain a clear record of the examination process.
Digital Forensic Reports
Depending on the nature of the assignment, the findings of a digital forensic investigation can be documented in a written technical report.
A report may describe:
- The device or digital material examined
- The scope and objective of the examination
- The methodology applied
- Relevant technical findings
- Digital evidence identified
- Conclusions supported by the examination
The level of detail depends on the purpose of the investigation and whether the findings are intended for private, corporate or legal use.
Digital Evidence for Legal Cases
Electronic information may be relevant in civil, criminal, family or corporate legal matters.
However, whether particular digital evidence is legally admissible depends on several factors, including how the information was obtained, who had lawful access to it and how it was preserved.
When digital evidence is expected to be used in legal proceedings, coordination with the client’s lawyer may be advisable from the beginning of the investigation.
This helps ensure that the objectives of the forensic examination are consistent with the requirements of the particular legal case.
Confidentiality and Data Protection
Digital forensic investigations can involve highly sensitive personal or corporate information.
For this reason, confidentiality is fundamental throughout the examination process.
Our work is conducted according to the circumstances of each case and with consideration for applicable Greek and European privacy and data-protection requirements.
Only information relevant to the authorised scope of the investigation should be examined and evaluated.
