Sqlite browser apple5/1/2023 ![]() These scan for orphaned content and flag up any old junk that looks like it might fit the context. They only recover the remaining content which is perfectly formed and includes a number of hints as to where it belongs. They use many different techniques that have been built and tested against thousands of different examples of deletion or corruption. In general, you can divide these tools into three categories: That said, it’s not too hard to get some data back, which is why you see a good number of tools on the market claiming to be able to do this. In particular, databases more than a few megabytes in size, and databases which have binary data in them can make the process a lot more difficult. As you’d expect, it’s all a bit fiddly, and there are a number of other technicalities that can emerge to make things difficult. The recovery technique then is pretty much what you expect: it’s about finding these orphaned files - complete or otherwise - and trying to find where they fit, and whether there’s enough data remaining for them to make sense. They’ve got a bunch of files in them, and where you’ve deleted data, those files will still be there, but with two caveats: they may have been partially or fully overwritten, and they’ll be unlabelled. The databases on it are like the filing cabinets we described earlier. Say you’ve been using your phone a couple of months. ❤️ Recovering deleted information from SQLite on iOS ![]() Before he did so, he was kind enough to describe iPhone Backup Extractor as “pretty awesome”. Jonathan was the grand master of iOS hacking until he went to work for Apple, helping beef up their security. If you’re interested to go deeper, we’d recommend Jonathan Zdziarski’s seminal book “ iPhone Forensics”. Well, yes, some of it, although there are many other aspects. And - unintuitively - it’s the process of adding newer data that really leads to older information being removed. What you might take from this is that it’s fast to delete data on your phone, and pretty fast to add it, assuming there’s space. If there’s no space to add more data, it’ll see if there are any of those unlabelled files hanging around, and if there are, it’ll chuck out whatever parts of them it needs to to make space. When it comes to adding more data, if there’s space your phone will add extra files. ![]() It just says “huh, forget about this”, and moves on. So the old data isn’t removed, it’s just left unlabelled (or “orphaned”, we as might technically call it.) This means that when you delete data, your phone doesn’t need to go through a relatively slow process of freeing up space in the cabinet.
