Offensive security assessments
Mobile
We validate this area during scoped assessments, documenting impact and remediation guidance.
Why it matters
- [ ] Establish a controlled and secure forensic environment. - [ ] Document the case background, scope, and objectives. - [ ] Ensure all forensic tools are up-to-date and compatible with the mobile OS being examined. - [ ] Verify that all necessary legal permissions and authorizations are in place.
How we test it
Our operators follow a structured checklist for this topic, adapted to your API surface and authentication model.
Testing approach
- Safely power off the mobile device to preserve its state.
- Use a write-blocker or equivalent device to prevent any write actions to the device.
- Create a forensic image (logical or physical) of the mobile device.
- Verify the integrity of the acquired image using checksums (e.g., MD5, SHA256).
- Analyze the file system structure to identify relevant files and directories.
- Examine system logs and artifacts for evidence of user activities.
- Retrieve call logs, SMS/MMS messages, and contacts.
- Check for installed applications and their associated data.

Engagement checklist
Items we validate during scoping and execution for this topic.
Pre-Investigation
- Establish a controlled and secure forensic environment.
- Document the case background, scope, and objectives.
- Ensure all forensic tools are up-to-date and compatible with the mobile OS being examined.
- Verify that all necessary legal permissions and authorizations are in place.
Device Acquisition
- Safely power off the mobile device to preserve its state.
- Use a write-blocker or equivalent device to prevent any write actions to the device.
- Create a forensic image (logical or physical) of the mobile device.
- Verify the integrity of the acquired image using checksums (e.g., MD5, SHA256).
Examination of Evidence
- Analyze the file system structure to identify relevant files and directories.
- Examine system logs and artifacts for evidence of user activities.
- Retrieve call logs, SMS/MMS messages, and contacts.
- Check for installed applications and their associated data.
- Examine browser history, cache, and cookies.
- Extract geolocation data and Wi-Fi connection history.
- Recover deleted files and artifacts, if necessary.
- Collect information about device settings, accounts, and connected networks.
Timeline Analysis
- Create a timeline of events and activities on the mobile device.
- Correlate events from different sources to establish a chronological sequence.
- Identify patterns or anomalies in user interactions.
Messaging App Analysis
- Extract data from popular messaging apps (WhatsApp, Signal, Telegram, etc.).
- Analyze chat conversations, attachments, and call logs.
- Recover deleted messages if possible.
Multimedia Analysis
- Examine photos, videos, and audio files for evidence.
- Extract metadata (timestamps, GPS coordinates, camera details).
- Identify tampering or manipulation of multimedia files.
- Check for hidden or encrypted files and folders.
Social Media and Cloud Data
- Investigate cloud backups and synced data (e.g., iCloud, Google Drive).
- Access and analyze social media accounts and activities.
- Examine email accounts and associated communication.
Data Recovery
- Use advanced data recovery techniques to retrieve deleted data.
- Handle encryption and decryption processes for secured data.
- Ensure data recovery does not alter or damage the original evidence.
Reporting and Documentation
- Create a comprehensive forensic report detailing findings, analysis, and conclusions.
- Document the forensic process, including acquisition, examination, and analysis steps.
- Include all relevant artifacts, logs, and extracted evidence in the report.
- Ensure the report is clear, concise, and well-organized.
Preservation of Evidence
- Store all forensic evidence securely to prevent tampering or loss.
- Maintain a record of who has accessed the evidence and for what purpose.
- Comply with legal and ethical guidelines for evidence preservation.
Legal Considerations
- Adhere to legal requirements and obtain necessary permissions for the investigation.
- Consult with legal counsel if required for handling sensitive cases.
