$ sudo osxpmem.app/osxpmem -V rdf: aff4: xsd: memory. So, without further ado, let’s take a look at the resulting AFF4 volume/file. However, for this post, I am using the default AFF4 output so that we may explore its use and features a bit. In addition, you may also export the memory image to a singular RAW or ELF file by using the “ –format elf” or “ –format raw” command line options if that suits your fancy. Though the documentation still shows it as a requirement, it’s actually not needed anymore and parses it all just fine. In the past, I used this option to collect the local /bin/bash file when Volatility used to require the bash shell’s memory address be provided in order to parse command history and produce associated timestamps when using the linux_bash plugin. You also have the option to include additional local files within the resulting AFF4 volume/file via the “ -i -i …” command line option(s), which can be useful in producing a singular output volume containing not only memory but other files (binaries/logs/etc.) you’d like to analyze as well. YES! It worked! As you can see, my system has 8GB of memory that was (by default) exported to an AFF4 volume/file called “mem.aff4”.

The file ownership/permissions must be changed to “root:wheel”. $ sudo kextutil -t osxpmem.app/MacPmem.kext/ĭiagnostics for osxpmem.app/MacPmem.kext:įile owner/permissions are incorrect (must be root:wheel, nonwritable by group/other): So, instead, let’s use the native utility kextutil’s “test” parameter (-t) to see if that gets us anywhere… Let me save you some time, as searching the system/kernel logs as suggested yields nothing useful.

Download latest release (as of this post, the latest osxpmem release is “2.1.post4”).So, what’s the easiest way to get up and running with the tool for memory acquisition? One of its greatest features is its output to an AFF4 volume, which has a ton of useful features (likely to be discussed in a dedicated post in the future as well).

While I will be delving into Rekall in a future post, for this we will simply be focusing on OSXpmem, which is an awesome command-line utility for quickly and easily collecting RAM from a Mac system. Rekall itself is actually a very useful utility built for both memory acquisition and live memory analysis on Windows, Linux, and OSX systems. OSXpmem is a part of the pmem suite created by the developers of Rekall. Let’s have a look at memory acquisition of OSX systems using a nifty tool called OSXpmem. Macs need love and disk/memory analysis as well, amirite? Well, with my most recent two part Mac post as well as this one, I’m attempting to change this, my friends! I find this odd, considering the surge in usage and deployment over the last several years, particularly within enterprises.

We see blog posts all the time about Windows forensics and malware analysis techniques, along with some Linux forensic analysis, but rarely do we see any posts about Mac technical/forensic analysis or techniques. Macs don’t get much love in the forensics community, aside from (Sarah Edwards), (Patrick Olsen), (Patrick Wardle), and a few other incredibly awesome pioneers in the field.
