When a file is deleted the key is wiped from the device. iOS uses an encryption system in which each file is encrypted with its own unique key. If a file, for example the entire database or a photograph, is actually deleted on the device it is not recoverable. Some of the more advanced solutions (Cellebrite CAS, Graykey) might be able to bet a full file system extraction, which could provide some additional data in the way of the WAL and SHM files, but even then you have a limited time period in which the data exists. I say what databases are included because app creators can flag whether the various databases for their apps are included in a backup (Facebook Messager for example is not). So, your ability to recover any deleted data will be limited to what databases are included and whether those databases have been vacuumed. Most of the forensic tools available just grab an iTunes backup of an iOS device. I raise what might be "captain obvious" because a lot of these companies and programs pitch this as a capability - but they appear to be not much more useful than a standard iTunes backup (except for some other features such as case export and AI file/image recognition etc).Ĭonsidering a typical scenario where a phone has had data deleted over a period of weeks, has been used normally and continuously during that period and was then submitted for analysis, it is not possible to recover those deleted artefacts. I would love for someone to explain to me otherwise, but from my understanding of the way the file system works and database are vacuumed, this has become an impossibility - no matter whether it's Cellebrite or anything else that is touted to be the top teir stuff. Read the FAQ before posting.Īs the title says - I am rapidly heading toward the opinion that DELETED data such as iMessage, Whatsapp, Call Logs CANNOT be recovered from a late model iphone running iOS14+ once deleted (without backup of course). Irrelvant submissions will be pruned in an effort towards tidiness. Vote based on the quality of the content. Topics include digital forensics, incident response, malware analysis, and more. This subreddit is not limited to just the computers and encompasses all media that may also fall under digital forensics (e.g., cellphones, video, etc.). The field is the application of several information security principles and aims to provide for attribution and event reconstruction following forth from audit processes. A community dedicated towards the branch of forensic science encompassing the recovery and investigation of material found in digital devices, often in relation to computer crime.
