Custom Recovery (TWRP & Co.) from an Android forensics perspective

Custom recoveries extend the maintenance and management capabilities of an Android device. They can be used for data backups, system modifications or installations. From a forensic perspective, their presence is an important technical finding that must be taken into account when assessing a device.

OUR APPROACH

This is how your examination will be carried out

A transparent process – from the initial enquiry to the handover of the report.

1
As part of the investigation, checks are carried out to determine whether there is any evidence of a custom recovery. Recovery partitions, boot configurations and other artefacts are analysed using recognised IT forensic tools as well as manually. All findings are fully documented and assessed solely on the basis of objective technical facts.
2
LanCologne produces expert reports for private individuals, as well as for companies and solicitors. Our reports have already been used in court proceedings. In some cases, we have been directly commissioned to produce IT forensic reports. Upon request, we can provide anonymised or redacted sample reports or extracts.

TYPICAL QUESTIONS

When is this analysis required?

  • ✔Is a custom recovery installed?
  • ✔What changes have been made?
  • ✔What are the implications for data integrity?
  • ✔What extraction options are available?
  • ✔What technical conclusions can be drawn?

LIMITATIONS & CONCLUSION

What you should know

The presence of a custom recovery does not prove that data has actually been tampered with. Similarly, the absence of a custom recovery does not rule out technical alterations. The assessment is always based on all available evidence.

Custom recoveries are technically relevant to Android forensics, as they provide insights into the device’s condition and any potential system modifications. However, a reliable assessment requires a comprehensive analysis of all available findings.
