Digital incidents are now part of everyday life – both in the business world and in our personal lives. In an economically strong region like Dortmund and the entire Ruhr area, companies, freelancers, and private individuals are increasingly confronted with cyberattacks, data theft, data loss, or sensitive conflict situations.

The IT forensics Dortmund provides support for the structured preservation and technical analysis of digital traces. The goal is to reconstruct complex digital processes in a traceable manner and create a clear overall picture.

As a central location in the Ruhr area, Dortmund is closely networked with cities such as Bochum, EssenDuisburg, Gelsenkirchen, Hagen, and Wuppertal. At the same time, there are strong connections to the Rhineland, particularly to Düsseldorf and Cologne. This regional network is not only economically relevant but also crucial for a strong local SEO structure.

Mobile phone forensics in Dortmund – Smartphones as a key source of evidence

Smartphones are one of the most important sources of digital evidence today. They contain extensive information about communication, behavior, and movements.

Mobile phone forensics in Dortmund enables an in-depth analysis of this data – even if content has been deleted or deliberately hidden.

Typical areas of analysis:

• Messenger services such as WhatsApp, Telegram or Signal
• Call logs and contact histories
• Location data and movement profiles
• Photos, videos and metadata
• App usage behavior
• Cloud synchronizations

Case study: Recovering deleted WhatsApp messages

A company in Dortmund suspected that internal information had been leaked via mobile communication. Shortly before an internal investigation, all chat histories were deleted.

As part of the IT forensic analysis, the smartphone was first fully secured. Subsequently, a detailed examination of the internal data structures was conducted, primarily focusing on the messenger databases, temporary storage areas, and timestamps.

Fragments of messages, evidence of file transfers, and communication patterns could be reconstructed. Particularly crucial was the chronological classification of the activities: when data was transferred, which contacts were involved, and how behavior changed during the relevant period.

This structured analysis enabled the creation of a comprehensible communication flow, which served as a basis for further decisions.

Case study: Infidelity – analyzing digital behavior patterns

A private client from Dortmund suspected his partner was having an affair. Evidence came from deleted messages, unusual communication times, and unexplained whereabouts.

The analysis focused not only on individual messages, but on the entirety of digital traces. These included:

• Communication times and frequencies
• recurring contacts
• Location trajectories
• temporal relationships between communication and movement

By combining this data, a consistent pattern could be reconstructed. Individual clues were thereby placed within a comprehensible overall context.

Case study: Suspected mobile phone surveillance

A client from Dortmund noticed unusual activity on his smartphone, including increased data usage, unexplained system processes, and conspicuous behavior of the device.

The investigation included:

• installed applications
• System processes
• Network Connections
• Authorization structures

analyzed.

During the process, unusual processes and connections were identified that indicated a potential security issue. Based on these findings, measures were developed to secure the device.

Cloud forensics in Dortmund – analysis of iCloud, Google and online data

Much digital data is no longer stored exclusively on devices, but rather in cloud systems. IT forensics in Dortmund enables the analysis of these data sources.

The following will be investigated:

• iCloud (Apple)
• Google Accounts (Android)
• Email systems
• Cloud storage

Case study: Cloud data recovery

In one case from Dortmund, locally stored data was only partially available. However, previous states could be reconstructed by analyzing cloud data.

Backups, synchronization statuses, and linked accounts were analyzed. These provided additional insights into the temporal development and usage.

Case study: Google data analysis on Android

Data from a linked Google account was analyzed on an Android device. This included:

• Location trajectories
• Search histories
• Device activities

This data enabled a detailed reconstruction of movements and usage patterns.

Data recovery in Dortmund – Recovery of Mac and Windows data

The IT forensics team in Dortmund assists with data recovery on:

• Windows systems
• macOS systems
• servers
• external storage devices

Case study: Data loss due to cyberattack

A company from Dortmund was affected by a cyberattack in which data was encrypted.

The analysis involved examining attack paths and evaluating existing data sources, including backups, temporary files, and system remnants.

By combining these approaches, parts of the data could be recovered and the attack could be traced.

Case study: Mac data recovery

A self-employed person lost important data due to a system error on a Mac.

The analysis showed that some data was still available. Documents and project files were reconstructed using targeted forensic methods.

Digital evidence preservation – legally sound and verifiable

A key component of IT forensics is the structured backup of digital data.

This ensures:

• Integrity of the original data
• complete documentation
• Traceability of all steps

The results can be used as a forensic report or expert opinion.
