We are excited to announce that on next Monday, December 15th, from
9AM-11AM PST, the Art of Memory Forensics authors will be doing an AMA
(Ask Me Anything) on Reddit's netsec.
This is a chance to ask us non-technical questions, comment on or ask
about the book, or anything else related to Volatility and memory
forensics.
The last book AMA on Reddit was for the Android Hacker's Handbook and it
will really well with over 300 comments (
https://www.reddit.com/r/netsec/comments/27zdxc/android_hackers_handbook_ama
) . We are hoping to have ours be big as well so please try to attend
and spread the word!

In the presentation I give an introduction to memory forensics and then
spend the rest of the time looking at Careto through the eyes of memory
forensics. Careto went undetected for over 7 years by the AV industry,
but in the talk you can see that memory forensics finds it over and over
again in only a few minutes.
PS: I gave a focused and more in-depth version of this talk at OMFW
(without the intro and hunting parts)

I've used malfind and memscan on a suspected POS infected system and I get a ton of false positive hits on AV processes. Any way to white list some of these or use --silent to filter out some of these false positives? On the other side, is it likely malware is using AV processes to do their deed?

Hi,
I'm trying to compile LiME for a given Android Virtual Device (AVD)
Platform 4.4.2
API Level 19
CPU Intel Atom (x86)
I have no information about how the AVD was created.
Does in this case investigation with LiME/Volatility make sense at all?
Should LiME be able to handle the Atom-Processor?
If yes: Should Volatility be able to handle the LiME dump?
If any answer up to now was no:
No further reading necessary. :-(
But please enlighten me. ;-)
If this in principle is not an impossible plan then how do I have to
handle the following warnings/errors?
(a) LiME compiles but gives me a
WARNING:
Symbol version dump ~/android/kernel/goldfish/Module.symvers
is missing; modules will have no dependencies and modversions.
(b) insmod fails
insmod: init_module '/sdcard/lime.ko' failed (No such file
or directory)
(but of course there is a '/sdcard/lime.ko')
(c) dmesg reports
lime: Unknown symbol _GLOBAL_OFFSET_TABLE_ (err 0)
lime: Unknown symbol kmap (err 0)
lime: Unknown symbol kunmap (err 0)
Is it correct to expect, that (b) and (c) are a result from (a)?
What is to be done?
Compiling the kernel and hope the Module.symvers fits to the AVD
symbols? The LiME documentation does not mention a need for compiling
the Android kernel.
Or do I have to work on the kernel's .config?
As always there is no /proc/config.gz on the phone/AVD. (At least I have
not seen any /proc/config.gz on my devices so far.)
Instead in this case I worked on the
goldfish/arch/x86/configs/i386_defconfig until the AVD accepted the
version magic.
Just in case it is useful, here is in detail what I did so far:
________________________________________

$ git log --pretty=oneline | grep -i 'linux 3.4$'
$ git checkout 76e10d1 -b goldfish-3.4-76e10d1
$ cp arch/x86/configs/i386_defconfig .config
________________________________________

Hello Group,
So am not sure, if I understood, the working of ldrmodules correctly, but
in short, for each process, I imagine it looks at the VAD; and for each dll
found there compares it with the 3 lists in the process PEB and reports
back on any discrepancy.
A snippet, from vadinfo for a process with pid 12128, I can see a dll mapped
VAD node @ 0xfffffa80088378c0 Start 0x0000000000040000 End
0x0000000000040fff Tag Vad
Flags: Protection: 7, VadType: 2
Protection: PAGE_EXECUTE_WRITECOPY
Vad Type: VadImageMap
ControlArea @fffffa8006a86c40 Segment fffff8a00021d4e0
Dereference list: Flink 00000000, Blink 00000000
NumberOfSectionReferences: 1 NumberOfPfnReferences: 1
NumberOfMappedViews: 119 NumberOfUserReferences: 120
WaitingForDeletion Event: 00000000
Control Flags: File: 1, Image: 1
FileObject @fffffa80069c5250, Name: \Windows\System32\apisetschema.dll
First prototype PTE: fffff8a00021d5a8 Last contiguous PTE: fffffffffffffffc
Flags2: Inherit: 1
But ldrmodules (or dlllist) over the image, does not show that dll.
cat ldrmodules.txt | grep -i apiset
cat dlllist.txt | grep -i apiset
The process in question has a pid of 12128, so on a frequency count, there
is a large discrepancy, that I don't understand why.
cat ldrmodules.txt | grep 12128 | wc -l
54
cat vadinfo-12128.txt | grep dll | wc -l
130
Any pointers to a link I should read up on to understand the concepts here.
Should not have ldrmodules, reported on all the dlls that were found as
mapped files in the VAD ?
Thanks,
JB
Does Volatility support the analysis of Mac /var/vm/sleepimage?
I did not see it mentioned in "The Art of Memory Forensics", and I
seem to have trouble even doing a simple mac_pslist against it...
