AFF4 Memory Image for RHEL 7.9 - No Suitable Address Space Mapping Found #797

Open jonnythefox opened 3 years ago

jonnythefox commented 3 years ago

Hello,

As part of some testing, I used Tanium Collection for Linux (memory) to recover memory from a RHEL 7.9 instance. Tanium uses pmem under the hood to dump an image in AFF4 format. I subsequently used this image to generate a profile, using the recovered boot/system.map-* and dwarfdump. I then cloned the most recent aff4 python plugin I could locate, added repo to PYTHONPATH, and then passed both parameters explicitly into the Vol command:

vol.py --plugins=/usr/local/lib/python2.7/pyaff4/pyaff4/aff4.py -f /home/user/Downloads/linux_mem_collection_test/memory_results/memory.zip --profile=Linuxrhel_79_maipo_profilex64 linux_pslist

Resultant output error - No suitable address space mapping found

Can anyone provide assistance - I'm not sure if this is a kernel issue, an image issue, or my command screw up for the plugin.

Thank you!

Have you tried extracting the memory sample from the zip file and running Volatility against that?

Thanks Gleeda. I did try to extract the physical memory stream to a raw file using linpmem but this also threw an error. Is that what you mean?

Running into the exact same issue. I basically followed the following instructions: https://schatzforensic.com/insideout/2018/06/how-to-analyse-aff4-linux-memory-images/ but running into the "No suitable address space mapping found."

I have tried extracting /proc/kcore from the AFF4 container and running volatility against that, but get the same error message.
