Introduction to Memory Forensics

Memory forensics is a specialized field within digital forensics that involves the analysis of a computer’s volatile memory (RAM) to extract evidence of system activity, running processes, network connections, and other crucial information that is lost when a system is powered down. Unlike traditional disk forensics, which focuses on analyzing static data stored on hard drives, memory forensics targets dynamic data that exists temporarily in a computer’s memory.

Definition and Importance of Memory Forensics

Definition

Memory forensics refers to the process of capturing and analyzing the contents of a system’s volatile memory (RAM) to uncover evidence of cybercrimes, attacks, and other system activities. It allows investigators to view processes, network connections, encryption keys, login credentials, malware, and other hidden evidence that may not be stored on a hard disk.

Importance

Volatile Data Retrieval: RAM stores temporary information, such as active processes, credentials, and data in use, that is lost once the machine is powered off. Memory forensics allows investigators to capture this data before it vanishes, which is critical for incident response and forensics.
Malware and Rootkit Detection: Memory forensics is especially useful for identifying sophisticated malware and rootkits that may hide themselves in memory to evade traditional disk-based detection methods.
Network Traffic Analysis: It can help uncover network connections, open ports, and even malicious network communication happening in real-time.
Encryption Key Recovery: Sometimes, critical encryption keys or passwords are stored in memory, and memory forensics can help recover them.
Live Evidence: Memory forensics often allows investigators to acquire evidence while the system is still running, preventing the loss of crucial information that might be overwritten during normal system operations.

Key Differences Between Disk Forensics and Memory Forensics

Aspect	Disk Forensics	Memory Forensics
Focus of Analysis	Examines data stored on physical or logical disk drives (e.g., hard drives, SSDs, USB drives).	Analyzes volatile data stored in the system’s RAM.
Data Volatility	Non-volatile; data persists after power-off.	Volatile; data is lost when the system is powered down.
Type of Information Retrieved	Accesses files, deleted data, partitions, metadata, and logs.	Retrieves active processes, open network connections, running applications, encryption keys, and malicious code.
Investigation Objectives	Recovers files, determines file access times, and traces historical user activity.	Identifies malicious activities, system state during breaches, and live malware evidence.
Tools and Techniques	Tools include EnCase, FTK, Autopsy, and Sleuth Kit for static analysis.	Tools like Volatility, Rekall, and Memdump analyze memory images and system states.
Challenges	Issues with encryption and large data volumes.	Requires timely memory capture and advanced obfuscation techniques.
Use Cases	Intellectual property theft, fraud investigations, and historical evidence recovery.	Incident response, malware analysis, and live intrusion detection.

Practical Memory Analysis Workflows

Identifying Malicious Processes

Using tools like pslist and pstree, investigators can:

Enumerate and analyze processes running in memory.
Examine process hierarchies to identify anomalies.
Detect discrepancies such as:
- Unusual parent-child relationships.
- Processes hiding under legitimate-looking names.
- Unknown or suspicious processes exhibiting abnormal behavior.

Example Workflow:

Run pslist:

vol.exe -f memory_dump.vmem --profile=Win7SP1x64 pslist

Lists active processes for analysis.

Run pstree:

vol.exe -f memory_dump.vmem --profile=Win7SP1x64 pstree

Displays hierarchical relationships among processes, helping to spot malicious activity.

Investigation of Running Processes

Investigating running processes is a crucial step in memory forensics, particularly when analyzing for potential malware, such as Cridex. This section outlines the approach to identifying suspicious processes using Volatility.

Steps for Investigating Running Processes

1. Checking for Suspicious Process Names

Malware often disguises itself under legitimate-sounding process names. A detailed inspection of the process list can help uncover anomalies.

2. Checking for Processes with Different Parent Process IDs (PPID)

Processes with unexpected or unusual parent process IDs can indicate tampering or injection by malicious actors. Analyzing the PPID relationships provides critical clues.

Case Example: Identifying `reader_sl.exe`

In this investigation, the malware is disguised under the process name reader_sl.exe.

Command for Analysis

To inspect the running processes and identify suspicious entries like reader_sl.exe, use the following Volatility command:

vol.exe -f cridex.vmem --profile=WinXPSP3x86 pslist

-f cridex.vmem: Specifies the memory dump file to analyze.
--profile=WinXPSP3x86: Defines the memory profile matching the target system (Windows XP SP3 x86).
pslist: Lists all running processes and their parent-child relationships.

While selecting the suspicious process name we will have to know what is the process functionality in addition what is the purpose of this suspicious process .

Based on the search, it is suspected that the infected host machine may have been compromised by malicious documents, such as .pdf or .docx.

Tracing the Creator of `reader_sl.exe`

Another plugin from Volatility, pstree, can be used to identify which process or program created reader_sl.exe. This analysis can provide additional indicators for investigation.

vol.exe -f cridex.vmem --profile=WinXPSP3x86 pstree

Analysis Using `pstree` Plugin

Based on the details provided by the pstree plugin, we have a clue that explorer.exe is creating reader_sl.exe. This potentially indicates that the infected host machine opened malicious documents, such as those received from an attacker.

Investigating a Process’s Internet Connection

Investigating a process’s internet connection in memory forensics is crucial for identifying potential malicious activities, such as communication with Command and Control (C&C) servers.

vol.exe -f cridex.vmem --profile=WinXPSP3x86 connscan

Processes with Remote Connections

During the analysis, two processes were identified as having made a connection to remote addresses:

explorer.exe
Suspected process: reader_sl.exe

Logical Analysis

A logical question arises: Why should reader_sl.exe establish an internet connection?

To further investigate, it is essential to check the remote IP address associated with this connection on VirusTotal or similar threat intelligence platforms for potential malicious activity.

Parent Process ID (PPID): 1484 (This is the PPID for reader_sl.exe.)

Advanced Memory Forensics Techniques

A. Process and Thread Analysis

Process Tree Reconstruction
- This technique involves mapping the parent-child relationships between processes in memory to detect anomalies in the process hierarchy.
- By reconstructing the full process tree, investigators can identify abnormal or unexpected relationships, such as hidden processes masquerading under legitimate ones, which could indicate the presence of malware.
Hidden and Injected Process Detection
- Tools such as psscan and malfind are essential for identifying stealthy processes or those injected into legitimate ones.
- These processes may not appear in standard process enumeration tools but can be detected by scanning memory for:
  - Suspicious code patterns
  - Altered process structures
  - Injected payloads
- Such findings often point to malicious activities.
Thread State Examination
- Analyzing thread activity is critical for uncovering potential malicious actions. Investigators should focus on:
  - Threads with unusual priorities
  - Abnormal execution states
  - Suspicious starting addresses
- Malicious threads may attempt to hijack legitimate processes or exploit system resources for nefarious purposes.
Kernel-mode Thread Analysis
- Investigating threads running in kernel mode is crucial, as they may signal the presence of rootkits or OS-level compromises.
- Rootkits often:
  - Operate at the kernel level to conceal activities.
  - Exhibit suspicious characteristics, such as hiding from user-mode monitoring tools.
  - Interact directly with the OS kernel to evade detection.

B. Investigating Timeline

The timeliner plugin in Volatility is used to create a timeline of events based on timestamps extracted from various artifacts in the memory image.
This timeline is invaluable for understanding the sequence of actions on a system, particularly during:
- Incident response
- Forensic investigations

Normal Use:

vol.exe -f cridex.vmem --profile=WinXPSP3x86 timeliner

Pipe Output to a Text File:

vol.exe -f cridex.vmem --profile=WinXPSP3x86 timeliner > timeline.txt

Investigation: Clipboard Hooking

The wndscan plugin in Volatility is utilized to scan for window objects in memory.
This functionality is particularly useful for identifying both visible and hidden windows created by processes, which may include:
- Malware-related activity
- Suspicious behavior

Normal Use:

vol.exe -f cridex.vmem --profile=WinXPSP3x86 wndscan

Pipe Output to a Text File:

vol.exe -f cridex.vmem --profile=WinXPSP3x86 wndscan > wnd.txt

Checking for Files: `filescan` Plugin

The filescan plugin in Volatility is used to identify file objects in memory that may not have been mapped to disk.
This is particularly useful for detecting hidden or injected files that could be used by malware.

vol.exe -f cridex.vmem --profile=WinXPSP3x86 filescan

Note : regarding to your time . we can use | findstr in windows or | grep in Linux to search for specific file on this

Checking for Malware: `malfind` Plugin

The malfind plugin in Volatility is a powerful tool for identifying potential malware within a memory dump.
It scans for injected code or anomalous memory sections that are typically associated with malware.

vol.exe -f cridex.vmem --profile=WinXPSP3x86 malfind

C. Memory Artifact Reconstruction

Registry Hive Recovery: Extracting and analyzing registry hives from memory to uncover configuration changes or malware persistence mechanisms.
Network Connection Tracking: Identifying live or historical network connections to analyze potential data exfiltration or communication with command-and-control (C2) servers.
Authentication Session Forensics: Investigating authentication tokens, session IDs, and user credential usage stored in memory.
Cached Credentials Examination: Analyzing cached credentials to detect potential credential harvesting or misuse.

Specialized Memory Forensics Domains

A. Rootkit and Stealth Malware Detection

Kernel-mode Rootkit Identification: Uncovering rootkits that operate at the kernel level by analyzing kernel memory and system structures.
Hooking Mechanism Detection: Detecting modifications to system call tables, inline hooks, or API hijacking techniques used by malware.
Memory-based Rootkit Analysis: Analyzing memory structures to identify hidden drivers, kernel modules, or other malicious artifacts.
Anti-forensic Technique Identification: Spotting attempts by malware to evade detection, such as memory wiping or data encryption.
