Mobile phone forensics in Cologne – evaluating smartphones and analyzing digital traces
Smartphones are among the most important digital evidence sources today. They contain a wealth of information about communication, behavior, and movements. Mobile phone forensics in Cologne enables in-depth analysis of this data – even when content has been deleted or obfuscated.

Messenger services such as WhatsApp, Telegram or Signal
SMS messages, call logs and contact histories
Location data and movement profiles
Photos, videos and their metadata
Usage data from apps
Links to cloud systems
Case study: Reconstruction of deleted WhatsApp communication
A company in Cologne suspected that confidential information about an employee had been passed on to a competitor. Shortly before leaving the company, the employee had deleted all chat histories from his smartphone.
As part of the forensic investigation, the device was first fully secured to ensure an unaltered data foundation. Subsequently, an in-depth analysis of the app structures, databases, temporary storage areas, and timestamps was carried out.
Fragments of messages, evidence of file transfers, and communication patterns could be reconstructed. Particularly crucial was the chronological classification of activities: when was data sent, when was it deleted, and which contacts were especially active during specific periods.
By combining this information, a more complete picture of the communication emerged, going far beyond individual messages and enabling a clear reconstruction of the facts.
Case study: Infidelity – Analysis of communication and movement patterns
A private client from Cologne suspected that his partner was having an affair. Indications included unusual communication times, deleted messages, and recurring absences.
The analysis created a comprehensive picture of digital activities. This included not only evaluating individual chats, but also:
temporal patterns of communication
Frequency and intensity of specific contacts
Location data over longer periods
Relationships between movement and communication behavior
By linking this data, a consistent pattern could be reconstructed. It became clear that certain contacts occurred regularly at specific times and correlated with specific locations.
The results were documented in a structured manner and could be presented comprehensibly within a legal context.
Case study: Suspected smartphone surveillance
A managing director from Cologne noticed that his smartphone was showing unusual activity, including increased data traffic, unusual background processes, and conspicuous device performance.
The forensic analysis included:
Checking installed applications
Analysis of ongoing processes
Investigation of network connections
Evaluation of authorization structures
Unusual connections to external servers and conspicuous system activity were detected. Additionally, potential vulnerabilities in the device configuration were identified.
Based on this, a comprehensive assessment of the security status was carried out and specific measures were developed to secure the device and avoid future risks.

The following will be investigated, among other things:
iCloud data on Apple devices
Google accounts and synchronization data
Email systems
Online storage solutions
Case study: Reconstruction of iCloud data
In a case from Cologne, important data was deleted from an iPhone. Only limited information remained on the device itself.
However, by analyzing iCloud, it was possible to reconstruct older states. These included contacts, image data, synchronization statuses, and indications of communication histories.
The cloud data provided an important complement to the local analysis and enabled a significantly more comprehensive reconstruction of the events.
Case study: Analyzing Google data on Android
An Android device was analyzed as part of an investigation into suspected misuse.
The focus was on the linked Google account. The following were evaluated:
Location history
Search history
Device activities
Synchronization events

backups
temporary files

System remnants
By combining these approaches, parts of the data could be reconstructed and the attack could be traced at the same time.
Case study: Mac data recovery
