As we outlined in the previous article (Effective Disk Imaging: Ports, Hubs, and Power), it’s better to connect external USB-C devices (such as adapters and especially write-blockers) to a USB-C port that complies with at least the USB 3.2 Gen2 specs (10 Gbit/s). But what if your computer only has USB-A ports, or only a USB-A port is free? Obviously, you’ll need a USB-C to USB-A cable – but you’ll need to choose the right one very carefully, and that’s not the only thing that matters.

Some time ago, we tested NVMe disk imaging performance (see When Speed Matters: Imaging Fast NVMe Drives), focusing mainly on software. This time, we turned our attention to hardware connections: which ports deliver the best results, and whether using a USB hub, active or passive, affects imaging speed and reliability.

In our previous post, Extracting and Analyzing Apple sysdiagnose Logs, we explained the difference between sysdiagnose logs and Apple Unified Logs. Today we’ll show how the latest build of iOS Forensic Toolkit can pull Unified Logs directly from an iPhone or iPad during advanced logical extraction.

Perfect Acquisition is the most sophisticated method for extracting data from compatible iOS devices. This method is completely forensically sound; it doesn’t modify a single bit of the filesystem. When supported, this method should always be used over alternatives. This guide outlines the entire process, from acquiring the data dump to decrypting and mounting it for analysis. Note: this guide applies to iOS Forensic Toolkit 8.80 and newer, in which the process has been made easier to use.

When an iPhone is seized and later re-examined, forensic teams sometimes find that data present in an earlier extraction are missing from a subsequent backup or filesystem image. Why exactly does that happen, what kinds of data are affected, how long do they usually live, and what can you do to preserve volatile and semi-volatile artifacts? Let’s try to find out.

“A core selling point of machine learning is discovery without understanding, which is why errors are particularly common in machine-learning-based science.” I could not resist the temptation to start this article with a quote by AI as Normal Technology – it captures the current state of AI-everything perfectly. Should investigators really trust black boxes running a set of non-deterministic algorithms and providing different results on every reroll? And can we still use such black boxes to automate routine operations? Let’s try to find out.
