Re: [Vol-users] procexedump Error: Cannot acquire process AS

by Dewhirst, Rob

I am aware of the tech preview tools (that I learned about sitting in scudette's class no less!) but I haven't had enough "stick time" with them to trust a remote user running a dump for me with them.

Hello All, I'm trying to create a profile for Android. First, I changed Makefile, and then executed make command. but, make command was failed. So, Could someone check the Makefile ? error message --- ubuntu:~/volatility-2.2/tools/linux$ make make ARCH=arm CROSS_COMPILE=~/android-ndk-r8/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi- EXTRA_CFLAGS=-fno-pic -C ~/goldfish CONFIG_DEBUG_INFO=y M=/home/td/volatility-2.2/tools/linux modules make[1]: Entering directory `/home/td/goldfish' CC [M] /home/td/volatility-2.2/tools/linux/module.o /home/td/volatility-2.2/tools/linux/module.c:212:5: warning: "STATS" is not defined /home/td/volatility-2.2/tools/linux/module.c:228:5: warning: "DEBUG" is not defined CC [M] /home/td/volatility-2.2/tools/linux/pmem.o In file included from /home/td/volatility-2.2/tools/linux/pmem.c:51: /home/td/goldfish/arch/arm/include/asm/mmzone.h:21:1: warning: "NODE_DATA" redefined In file included from include/linux/gfp.h:4, from include/linux/kmod.h:22, <snip> /home/td/volatility-2.2/tools/linux/pmem.c: In function 'pmem_read_partial': /home/td/volatility-2.2/tools/linux/pmem.c:142: warning: comparison of distinct pointer types lacks a cast make[2]: *** [/home/td/volatility-2.2/tools/linux/pmem.o] Error 1 make[1]: *** [_module_/home/td/volatility-2.2/tools/linux] Error 2 make[1]: Leaving directory `/home/td/goldfish' make: *** [dwarf] Error 2 --- Makefile --- obj-m += module.o obj-m += pmem.o KDIR := ~/goldfish CCPATH := ~/android-ndk-r8/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin -include version.mk all: dwarf pmem pmem: pmem.c $(MAKE) ARCH=arm CROSS_COMPILE=$(CCPATH)/arm-linux-androideabi- EXTRA_CFLAGS=-fno-pic -C $(KDIR) M=$(PWD) modules dwarf: module.c $(MAKE) ARCH=arm CROSS_COMPILE=$(CCPATH)/arm-linux-androideabi- EXTRA_CFLAGS=-fno-pic -C $(KDIR) CONFIG_DEBUG_INFO=y M=$(PWD) modules dwarfdump -di module.ko > module.dwarf $(MAKE) ARCH=arm CROSS_COMPILE=$(CCPATH)/arm-linux-androideabi- EXTRA_CFLAGS=-fno-pic -C $(KDIR) M=$(PWD) clean clean: $(MAKE) ARCH=arm CROSS_COMPILE=$(CCPATH)/arm-linux-androideabi- EXTRA_CFLAGS=-fno-pic -C $(KDIR) M=$(PWD) clean rm module.dwarf --- Thanks, Tad

Android Plugin: Missing gDvm type definition

by Dario Schwab

Hi We are trying to reproduce the steps to access application specific informations from Android phones as Andrew Case demonstrated here: http://digitalforensicssolutions.com/papers/android-memory-analysis.pdf (Page 17 and following) We already have a Android Profile for our Goldfish kernel and are able to run the existing plugins (e.g. linux_pslist) against the memory dump acquired from the emulator. Now we are writing our own Volatility Plugin according to Andrews presentation. But so far we could not instantiate a DvmGlobals object as Volatility does not know this specific type. A snippet from our plugin: gDvm = obj.Object("DvmGlobals", vm = self.addr_space, offset = gDvm_addr) When run, Volatility prints the following warning: WARNING : volatility.obj : Cant find object DvmGlobals in profile <volatility.plugins.overlays.linux.linux.LinuxAndroid_Goldfishx86 object at 0x3a57910>? How can we get Volatility to know this object type? We pulled libdvm.so from our emulator and disassembled it using arm-linux-androideabi-objdump and found the following: *000aa1a8 *<gDvm>: This lines up with the DWARF informations from libdvm.so we compiled ourselves: <1><0x12484><DW_TAG_variable> DW_AT_name<"gDvm"> DW_AT_decl_file<0x00000001 dalvik/vm/Init.cpp> DW_AT_decl_line<0x00000032> DW_AT_type<<0x0000c3b8>> DW_AT_external<yes(1)> DW_AT_location<DW_OP_addr *0x000aa1a8*> We aren't sure if this address actually is what we are looking for, that is the offset of gDvm in the memory dump. Can you confirm this? Thanks for any help Alex & Dario

Understanding 'sessions'

by Brett Cunningham

I RDP'ed into another VM, opened notepad, regedit and cmd in order to reenact the sessions plugin. I didn't get the expected output as was on the blog post ( http://volatility-labs.blogspot.com/2012/09/movp-11-logon-sessions-processe…) It shows up under the main RDP console ID. I'm guessing that this is because I'm using WinXP and it doesn't support multiple logins.
