This plugin prints details of process memory, including heaps, stacks, and shared libraries. In the example below from a KBeast infection, you can see the rootkit module in a hidden directory (with prefix *h4x*) starting at 0x8048000 in the memory of process with pid 2777.

You can then specify that base address as the -s/--vma option to linux_dump_map to acquire the data in that memory segment. Use it with the -O/--output-file parameter to save to disk.
$ python vol.py --profile=LinuxDebianx86 -f kbeast.lime linux_dump_map -p 2777 -s 0x8048000 -O h4xbd
And you can verify what was extracted:
$ file h4xbd
bin22: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), statically linked (uses shared libs), stripped
$ readelf -s h4xbd
readelf: Error: Unable to read in 0x28 bytes of section headers
readelf: Error: Unable to read in 0x5a0 bytes of section headers
readelf: Error: Unable to read in 0xd0 bytes of dynamic section
Note that readelf is unable to process the file. To recover the file in-tact, we need to acquire it from the page cache using the linux_find_file plugin. This is because the page cache holds all the physical pages backing a file in memory without any modifications.
This plugin dumps a memory range specified by the -s/--vma parameter to disk. For a description, see the section in linux_proc_maps above.
This plugin recovers bash history from memory, even in the face of anti-forensics (for example if HISTSIZE is set to 0 or HISTFILE is pointed to /dev/null). For more information, see MoVP 1.4 Average Coder Rootkit, Bash History, and Elevated Processes.
The argument to the -H/--history_list parameter can be gathered by using gdb on a live system. As shown below, the value you supply is 0x6ed4a0 (this was not calculated by us, its in a comment of the gdb output). For some systems, such as OpenSuSE, the history_list symbol is in a shared library (readline.so) instead of /bin/bash and ASLR is enabled. In those cases, its not a static value, and the linux_bash plugin will not work. The -P/--printunalloc argument tells the plugin to print unallocated/deleted commands (can sometimes yield invalid data).

Note: The -H/--history_list argument is now optional starting with Volatility 2.3. If you don't supply it, we now scan in a brute-force manner and automatically find the value. This is critical to being able to find bash history in memory when you don't have access to a live system on which to run gdb. By default, in the brute force mode, we only check processes named "bash" however if an attacker copies /bin/bash to /tmp/a then there may be fragments of attacker's commands in a process named "a" so use -A/--scan_all to scan all processes regardless of their name.
This plugin prints the list of loaded kernel modules starting at the modules symbol and walking the modules.list linked list. It optionally can print the module section information (with the -S/--sections option) or the module load parameters (with the --P/--params option).

This plugins lists and recovers tmpfs filesystems from memory. This is very useful in forensics investigations as these filesystems are never written to disk and attackers leverage this fact to hide their data in places like /dev/shm.
To use this plugin you must first list the tmpfs filesystems with the "L" option:
# python vol.py --profile=Linuxthisx86 -f after-blog-post.lime linux_tmpfs -L
Volatility Foundation Volatility Framework 2.2
1 -> /dev/shm

This plugin detects the second kernel level keylogging method described in "Bridging the Semantic Gap to Mitigate Kernel-level Keyloggers". It works by walking the kernel "keyboard_notifier_list" and checking if each notifier (callback) is within the kernel. If the callback is malicious then its symbol name is printed, otherwise "HOOKED" is printed.
This plugin detects rootkits that have elevated privileges to root using DKOM techniques.
On older 2.6 kernels, the user ID and group ID of a process were kept as simple integers in memory. For a rootkit to elevate the privileges of a process, it simply set these two values to zero. This simplicity also made it very difficult to use only the information in the process structure itself to detect which processes had been elevated and which were simply spawned by root.
This changed in later versions of 2.6 as the kernel adopted a cred structure to hold all information related to the privileges of a process. This structure is fairly complicated and forced rootkits to adapt their process elevation methods. Although the kernel provides the prepare_creds and commit_creds functions to allocate and store new credentials, a number of rootkits choose not to use this functionality. Instead, they simply find another process that has the privileges of root and that never exits, usually PID 1, and set the cred pointer of the target process to that of PID 1’s. This effectively gives the attacker’s process full control and the rootkit does not have to attempt the non-trivial task of allocating its own cred structure.
The borrowing of cred structures leads to an inconsistency that Volatility can leverage to find elevated processes. In the normal workings of the kernel, every process gets a unique cred structure and they are never shared or borrowed. The linux_check_creds plugin utilizes this by building a mapping of processes and their cred structures and then reports any processes that share them.
The following output shows the cred structure running on an infected VM and showing that PID 1 has the same cred structure as the elevated bash shell (PID 9673):

This plugin enumerates the /proc filesystem and all opened files and verifies that each member of every file_operations structure is valid (valid means the function pointer is either in the kernel or in a known (not hidden) loadable kernel module).

As we can see from the output, Volatility was able to report the three hooks placed by Average Coder (readdir from root of proc, write of buddyinfo, and read of modules), by enumerating all the files and directories under /proc and verifying their members. From here, the investigator knows the machine is compromised and can begin to investigate the rootkit.
This plugin, when given the –i/--inode option, reads the inode at the given address and verifies each member of its i_fop pointer.

This plugin finds rootkits that break themselves from the module list but not sysfs. We have never found a rootkit that actually removes itself from sysfs, so on a live system they are hidden from lsmod and /proc/modules, but can still be found under /sys/modules. We perform the same differnecing with the in-memory data structures. For more information, see MoVP 1.5 KBeast Rootkit, Detecting Hidden Modules, and sysfs.

The purpose of this plugin is to check if any processes are sharing 'cred' structures. In the beginning of the 2.6 kernel series, the user ID and group ID were just simple integers, so rootkits could elevate the privleges of userland processes by setting these to 0 (root). In later kernels, credentials are kept in a fairly complicated 'cred' structure. So now rootkits instead of allocating and setting their own 'cred' structure simply set a processes cred structure to be that of another root process that does not exit (usually init / pid 1). This plugin checks for any processes sharing 'cred' structures and reports them as the kernel would normally never do this. It finds a wide range of rootkits and rootkit activity and you can focus your investigation on elevated process (i.e. bash)
This plugin prints the ARP table.

This plugin mimics the netstat command on a live system. It leverages the linux_lsof functionality to list open files in each process. For every file, it checks if the f_op member is a socket_file_ops or the dentry.d_op is a sockfs_dentry_operations structure. It then translates those to the proper inet_sock structure. The -U/--ignore-unix option will ignore Unix sockets and only print TCP/IP entries.

This plugin is typically used in two steps. First you find the inode to a file in the following manner:
$ python vol.py -f avgcoder.mem --profile=LinuxCentOS63x64 linux_find_file -F "/var/run/utmp"
Volatility Foundation Volatility Framework 2.2_rc1
Inode Number Inode
---------------- ------------------
130564 0x88007a85acc0
Then the supply the Inode value (not the Inode Number) as the -i/--inode parameter in order to dump the cached file contents from memory. In the command below, the -O parameter specifies where to dump the resulting file.
$ python vol.py -f avgcoder.mem --profile=LinuxCentOS63x64 linux_find_file -i 0x88007a85acc0 -O utmp
Now we have a file named "utmp" which was extracted from the memory sample. You can run the who command on this file to determine who was logged in:
$ who utmp
centoslive tty1 2013-08-09 16:26 (:0)
centoslive pts/0 2013-08-09 16:28 (:0.0)
This plugins works by walking the kmem_cache of vm_area_struct structures. These structures represent a memory mapping within a process and hold information such as the mapped file, starting and ending addresses, and permissions. Depending on how the kernel is compiled, these structures may also hold a pointer to the task_struct (process) that opened or still has open the mapping. The "-u" flag can be passed to the plugin to find information on mappings that were closed or that were opened by processes that exited.

This plugin presents an interactive shell in the linux memory image. You can use it to simply list processes:
$ python vol.py --profile=LinuxUbuntux64 -f ~/ubuntu.lime linux_volshell
Volatility Foundation Volatility Framework 2.3_alpha
Current context: process init, pid=1 DTB=0x366ec000
Welcome to volshell! Current memory image is:
file:///Users/michaelligh/Desktop/ubuntu.lime
To get help, type 'hh()'
>>> ps()
Name PID Offset
init 1 0xffff88007b818000
kthreadd 2 0xffff88007b8196f0
ksoftirqd/0 3 0xffff88007b81ade0
kworker/0:0 4 0xffff88007b81c4d0
kworker/u:0 5 0xffff88007b81dbc0
[snip]
You can print linux data structures and overlay them on a particular offset in an address space:
>>> dt("task_struct")
'task_struct' (5872 bytes)
0x0 : state ['long']
0x8 : stack ['pointer', ['void']]
0x10 : usage ['__unnamed_910']
0x14 : flags ['unsigned int']
0x18 : ptrace ['unsigned int']
0x20 : wake_entry ['llist_node']
0x28 : on_cpu ['int']
[snip]
>>> dt("task_struct", 0xffff88007b818000)
[task_struct task_struct] @ 0xFFFF88007B818000
0x0 : state 1
0x8 : stack 18446612134386278400
0x10 : usage 18446612134386302992
0x14 : flags 4202752
0x18 : ptrace 0
0x20 : wake_entry 18446612134386303008
0x28 : on_cpu 0
[snip]
You can change into a specific process's context and then access the task_struct object as self.proc:
>>> cc(pid = 11370)
Current context: process firefox, pid=11370 DTB=0x308a8000
>>> self.proc.comm
[String comm] @ 0xFFFF88005B8BE020
>>> str(self.proc.comm)
'firefox'
After doing so, any of the db/dd/dq commands will output data from the process's address space.
This plugin allows you to scan for Yara rules anywhere in process or kernel memory. The rules can be supplied on command-line (-Y) or in a file on disk (-y). In the example below, we limit our scan to one process (firefox pid 11370) and look for URLs:
$ python vol.py --profile=LinuxUbuntux64 -f ~/ubuntu.lime linux_yarascan -Y "http://" -p 11370

To scan all processes, just leave off the -p parameter (or to scan multiple processes use -p 1,2,3 syntax). You can also scan kernel memory using the --kernel option.
