In the realm of mobile forensics, iTunes backups have long been a common method for extracting data from iOS devices. However, the increasing sophistication of mobile devices and the evolving landscape of digital evidence have exposed the limitations of iTunes backups as a complete source of evidence in investigations.

The Illusion of Completeness

One of the primary shortcomings of iTunes backups is their incompleteness when you compare it to getting a full file system extraction. While iTunes backups may capture a significant portion of the device’s data, they sometimes fail to include important system files, third-party applications and secure enclaves. This could lead to misleading conclusions and hinder justice.

For instance, important information that is stored in database freepages and/or logs are not available in iTunes backups, potentially concealing critical conversations or exchanges that could be central to an investigation. Similarly, data stored within some messaging applications may have additional protections and may not be accessible through iTunes backups, potentially leaving valuable evidence behind.

Be Aware of Time Stamps

It’s important to be aware of time stamps in iTunes backups, which can further complicate their use in investigations. While most timestamps are in iTunes backups, take note that “Changed” and “Accessed” times could be missing. Establishing a clear timeline of events is crucial in investigations, as it allows investigators to understand the sequence of events, identify patterns and corroborate witness statements. When timestamps are misconstrued iTunes backups, it can make it difficult to accurately place data within the context of a timeline, potentially leading to misinterpretations.

Ensuring Chain of Custody

In investigations where multiple people could have access to the data, security provided by hashing ensures a proper chain of custody. Hashing gives you the ability to provide clear evidence that the data you’re presenting as part of the investigation is the same data that was extracted – and iTunes Backups do not inherently have this feature.
