conducting-memory-forensics-with-volatility

Performs memory forensics analysis using Volatility 3 to extract evidence of malware execution, process injection, network connections, and credential theft from RAM dumps captured during incident response. Covers memory acquisition, process analysis, DLL inspection, and malware detection. Activates for requests involving memory forensics, RAM analysis, Volatility framework, memory dump investigation, volatile evidence analysis, or live memory acquisition.

Conducting Memory Forensics with Volatility

When to Use

An endpoint has been contained during an active incident and volatile evidence must be preserved
EDR alerts suggest process injection or fileless malware that only exists in memory
Encryption keys need to be recovered from a ransomware-infected system before shutdown
Credential theft (Mimikatz, LSASS dumping) is suspected and evidence must be confirmed
A rootkit or kernel-level compromise is suspected and disk-based analysis is insufficient

Do not use for analyzing disk images or file system artifacts; use disk forensics tools (Autopsy, FTK) for those tasks.

Prerequisites

Memory acquisition tool deployed or available: WinPmem, Magnet RAM Capture, DumpIt, or AVML (Linux)
Volatility 3 installed with Python 3.8+ and required symbol tables
Sufficient storage for memory dumps (equal to system RAM size, typically 8-64 GB)
YARA rules for malware detection in memory (Florian Roth's signature-base, custom rules)
Reference baseline of normal processes and DLLs for the OS version being analyzed
Chain of custody documentation for evidence handling

Workflow

Step 1: Acquire Memory Image

Capture RAM from the target system using a forensically sound method:

Windows (WinPmem):

winpmem_mini_x64.exe output.raw

Windows (Magnet RAM Capture):

MagnetRAMCapture.exe
# GUI-based, select output path, generates .raw file

Windows (DumpIt):

DumpIt.exe
# Creates memory dump in current directory automatically

Linux (AVML - Acquire Volatile Memory for Linux):

./avml output.lime

Document acquisition metadata:

Acquisition Record:
━━━━━━━━━━━━━━━━━
Target Host:      WKSTN-042
RAM Size:         16 GB
Dump File:        WKSTN-042_20251115_1445.raw
Dump Size:        16,843,612,160 bytes
SHA-256:          a4b3c2d1e5f6...
Acquisition Tool: WinPmem 4.0
Acquired By:      [Analyst Name]
Timestamp:        2025-11-15T14:45:00Z

Step 2: Identify the Operating System and Profile

Volatility 3 automatically identifies the OS, but verify:

# Get system information
vol -f WKSTN-042_20251115_1445.raw windows.info

# Output includes:
# OS: Windows 10 22H2 (Build 19045.3693)

# List all running processes
vol -f memory.raw windows.pslist

# Show process tree (parent-child relationships)
vol -f memory.raw windows.pstree

# Scan for hidden/unlinked processes (rootkit detection)
vol -f memory.raw windows.psscan

# Compare pslist vs psscan to find hidden processes
# Processes in psscan but NOT in pslist may be hidden by rootkits

# List all network connections
vol -f memory.raw windows.netscan

# Focus output fields:
# Offset    Proto  LocalAddr     LocalPort  ForeignAddr    ForeignPort  State     PID  Owner
# 0xe10...  TCPv4  10.1.5.42     49721     185.220.101.42  443         ESTAB     3847  update.exe

# Detect injected code in processes
vol -f memory.raw windows.malfind

# Output shows:
# PID  Process       Start      End        Tag  Protection  Hexdump/Disassembly
# 3847 explorer.exe  0x2a10000  0x2a14000  VadS PAGE_EXECUTE_READWRITE
# MZ header detected - injected PE

# Dump suspicious process memory
vol -f memory.raw windows.memmap --pid 3847 --dump

# List DLLs loaded by a suspicious process
vol -f memory.raw windows.dlllist --pid 3847

# Scan memory with YARA rules
vol -f memory.raw windows.yarascan --yara-file malware_rules.yar

# Dump registry hives from memory (for password hash extraction)
vol -f memory.raw windows.registry.hivelist
vol -f memory.raw windows.hashdump

# Extract command line history
vol -f memory.raw windows.cmdline

# List handles (files, registry keys, mutexes)
vol -f memory.raw windows.handles --pid 3847

# Extract clipboard contents
vol -f memory.raw windows.clipboard

# Dump cached files from memory
vol -f memory.raw windows.dumpfiles --pid 3847

Term	Definition
Volatile Evidence	Data that exists only in RAM and is lost when a system is powered off; includes running processes, network connections, encryption keys
Process Injection	Technique where malware inserts code into a legitimate process's memory space to evade detection (malfind detects this)
EPROCESS	Windows kernel data structure representing a process; psscan searches for these structures even when unlinked from the active process list
VAD (Virtual Address Descriptor)	Windows kernel structure tracking memory regions allocated to a process; malfind examines VADs for executable but non-file-backed regions
Symbol Tables	OS-specific data structures that Volatility 3 uses to parse memory; downloaded automatically based on detected OS version
PAGE_EXECUTE_READWRITE	Memory protection flag indicating a region is readable, writable, and executable; common indicator of injected malicious code
Memory-Resident Malware	Malware that operates entirely in RAM without writing persistent files to disk, making it invisible to traditional disk-based antivirus
