How secure are your chats in your favorite instant messenger? Can someone intercept and read your secret conversations, and can you do something about it? Apple users have access to the highly popular instant messaging system, the iMessage. But how secure it really is? Let’s find out.

Believe me or not, but this is exactly the 500th post in our blog! The first one was posted in March 2009 and was about Distributed Password Recovery and GPU acceleration. At that time, we even did not do mobile or cloud forensics. Today it’s not about our achievements. I want to thank you for being with us, and share a few bits and pieces about our blog that you may find handy or at least amusing.

Apple iMessage is an important communication channel and an essential part of forensic acquisition efforts. iMessage chats are reasonably secure. Your ability to extract iMessages as well as the available sources of extraction will depend on several factors. Let’s discuss the factors that may affect your ability to extract, and what you can do to overcome them.

Remember the good old times when there was a lot of applications with “snake oil” encryption? You know, the kind of “peace of mind” protection that allowed recovering or removing the original plaintext password instantly? It is still the case for a few “we-don’t-care” apps such as QuickBooks 2021, but all of the better tools can no longer be cracked that easily. Let’s review some password recovery strategies used in our software today.

If the iPhone is locked with a passcode, it is considered reasonably secure. The exception are some older devices, which are relatively vulnerable. But what if the passcode is known or is not set? Will it be easy to gain access to all of the data stored in the device? And why do we have the countless forensic tools –is analysis and reporting the sole reason for their existence? Not really. If you’ve been wondering what this acquisition thing is all about, this article is for you.

We all have habits. Morning coffee (no sugar, just some milk), two eggs (sunny side up), reading mail wile you are not completely awaken, and a lot more. We all follow some kind of rules we have set for ourselves. We all have some favorites: names, cities and even numbers; maybe an important date or place. Can we exploit people’s habits to break their passwords effectively instead of using brute force? We can, and here’s the how-to.

Virtual machines use a portable, hardware-independent environment to perform essentially the same role as an actual computer. Activities performed under the virtual umbrella leave trails mostly in the VM image files and not on the host computer. The ability to analyze virtual machines becomes essential when performing digital investigations.

Making tools for breaking passwords, I am frequently asked whether it’s legal, or how it works, or what one can do to protect their password from being cracked. There are people who have “nothing to hide”. There are those wearing tin foil hats, but there are a lot more people who can make a reasonable effort to secure their lives without going overboard. This article is for them.

The year was 2008, and I had been staying at a hotel in Bogota. This trip was just one of many to Columbia that year. Before my trip, I’d had my former girlfriend, Darci, stop by and help me swap out the hard drive in my MacBook Pro laptop. Remember, this is 2008, and at the time, replacing a drive in a MacBook Pro wasn’t nearly as easy as replacing hard drives these days. Darci swapped out my original hard drive with a brand-new drive, which I then formatted and installed macOS.  I had her swap the drive out for security reasons. I didn’t want to cross the border into a foreign country with all of my client data. Especially not after what happened to me in Atlanta! But we’ll get to that later.

When investigating iOS devices, you may have seen references to the SoC generation. Security researchers and developers of various iOS jailbreaks and exploits often list a few iPhone models followed by a note that mentions “compatible iPad models”. This is especially common when discussing iOS forensics, particularly referring to the checkra1n jailbreak. What do those references mean, and how are the iPhone and iPad models related? Can we count the iPod Touch and Apple TV, too? Let’s have a look.
