1. Introduction
Cybercrime can be defined as a crime committed in cyberspace with computer media.
Disclosure of the cybercrime is known as digital forensics [1]. Digital forensics is a branch of
forensic science pertaining to legal evidence found in computers and digital storage media such
as flash drives, hard disk, or CD-ROM), electronic documents (such as email messages, video,
or JPEG) or even a series of data packets in network [2]. The involvement of such a device in a
computer crime is divided into three, namely: a destination computer, the computer becomes a
means to make crime and computer functions to store all the information that it contains a criminal
offence [3]. Digital forensics (computer forensics) is a discipline used to search digital evidence
with scientific methods for the identification, preservation, extraction and documentation of digital
evidence derived from digital sources to enable successful prosecution. The goal of digital
forensics is to obtain legal evidence found in digital media [4]
The initial process of digital forensic namely the phase of data acquisition, which is the
phase in which investigators make a perfect copy of the storage medium and Random Access
Memory [5]. Investigators should be aware of all the changes data quickly. Because many of the
techniques that take a long time, the software is expensive and specialized training, this makes
the investigator choose a particular expertise in the field, one of which is Live Forensic. Live
Forensic is a technique in the data acquisition phase need a computer that is being lit, the data
that are running on that computer also called volatile data [6]. The success of the investigation
depends on the quality of data collected. The quality of the copied data contains completeness of
information such as information access, time and users, data quality is also affected by artefacts
(Registry Key, DLL) left by the use of software acquisition [7]. Processing time, DLL, Registry Key
and Memory Usage will impact to potential evidence. Data stored in RAM is data that is easy to
change because data cannot be recovered after the user turns off the computer [8]. The forensics
artefacts left by the web browser after the end of this session is not just a list of web visits, cookies,
and downloads. These artefacts also contain the sites the user visits, the time and frequency of
access, and also the search engine keywords used. When conducting a digital investigation of a
system, investigators may collect evidence of the artefacts [9] . Investigators should distinguish
tools that can only collect data and analyze them. There is a toolkit from the market that allows

collecting digital evidence from computers such as RAM and DISK [10]. Figure 1 shows 41
respondents in the USA about using acquisition software for digital forensics. FTK Imager ranked
first with 23%, then Memoryze ranked second with 21% and ProDiscover with 16%, Belkasoft
with 10%, while DumpIt and Windows Memory Reader only 7% of the total 41 respondents [7].
Figure 1. The Use of Software Acquisition Forensics
Information or Data can be found by analyzing RAM depending on the computer and
operating system used [5]. The most valuable information: the active processes, information about
open files, Registry Key, information about the activities of the network, the drivers used, user
login, password and cryptographic key, hidden processes and data, malware, data temporarily,
portable applications (applications that do not installed on the computer itself but only run), use
etc., the session and lots of other important information [11] [12]. Windows Version uses Windows
10 operating system with 42,37% and Windows 7 with 42,14%, followed by 8,59% of Windows
8.1 and Windows XP to 3,66%. The use of the Windows Version in the world can be seen in
Figure 2 [13].

Forensic Toolkit Imager (FTK Imager) [14] is a forensics tool freeware developed by
AccessData who have supported the researcher digital to conduct computer forensic
examinations are complete of obtaining a forensic image of both the physical memory and logical,
read the forensic image, decrypt the data, and reporting of digital evidence. Memoryze is a
freeware forensic tool that has been developed by Mandiant. Memoryze not only can acquire
physical memory from a Windows system but also can perform analysis of live memory while the
computer is running. All analyses can be done either on the image that is acquired or a live system
[15]. DumpIt is a freeware command-line tool developed by MoonSols. This tool allows for the

acquisition of physical memory and saves the results as a raw file for later analysis [16]. Belkasoft
Live Ram Capturer is a small and very powerful tool to get the memory to the operating system.
An excellent feature of Belkasoft RAM Capturer Live is able to manage to acquire memory from
the system with anti-debugging and anti-dumping memory enabled [17]. Magnet RAM Capture is
a freeware tool designed to capture the computer's memory that allows researchers to recover
and analyze valuable artefacts, as well as all the activities, are not usually stored on the local hard
disk [18].
2. Related Work
Some results from the research were given by Aljaedi, et.al in [19] shows the effect of
implementing Live Response forensic toolkit, which changed significantly volatile data
environment in some cases and can override the potential evidence. memory image analysis is
also used as an alternative approach that helps reduce the risk of losing evidence volatile. This
comparative analysis calls attention to the ability of both methods of retrieving and recovering
volatile data. Hausknecht, et.al in [12] that shows and explains the importance of the data live
forensic and artefacts that can be found as well as the methods and tools used to extract and
analyze data from RAM. Moreover, it also shows that sometimes the forensic investigation, the
data contained in RAM can contain sufficient evidence to settle the whole case. Mcdown, et al. in
[7] Acquisition software selection greatly affects the quality of the data when copying. The results
of research analyzing the memory depth at seven acquisition software that runs on Windows 7
that FTK Imager, Belkasoft RAM Capturer, ProDiscover, Windows Memory Reader, WinEn,
DumpIt and Memoryze. RAM usage when software is being run showed different results. Relics
artefacts in FTK Imager Pro 10 times more compared with Belkasoft and Windows Memory
Reader, 8 times more than WinEn, and 5 times more than DumpIt and Memoryze. These artefacts
can overwrite important forensic content in RAM, which will negatively affect the investigation.
Campbell in [20] the other four tested software is Windows Memory Reader, WinPmem, FTK
Imager and DumpIt) were tested against two criteria (impact and completeness). WMR and
DumpIt found to have the least impact, and also showed the greatest accuracy throughout the
experiment.
Belsare and Sinha in [21] showed Software and Hardware for acquisition and storage of
memory Live in getting the processes that occur during a system to turn widely available. the use
of hardware does not have an impact on the data acquired but the price for this method is too
expensive, while the use of methods of software will have an impact on the data obtained. the
purpose of this research is the algorithm to make the collected data is authentic and can be
accepted in court. Meera, Isaac and Balan in [22] that cybercrime will thrive on the virtual machine
and the techniques used must be appropriate, such as acquisition technique in obtaining VMware
via live internal file and analyzes the files obtained from the raw data stored in various grains.
Kolhe and Ahirao in [23] research examined tools for acquisition in live and dead forensics.
This Live or dead method depends on the target. this research produces the advantages and
disadvantages of both methods with acquisition tools as a comparison. the results of this study
are recommended to use the live forensics method because this method is the best way to
investigate in a short time because it takes data only on RAM that is running, it is far more effective
than dead forensics
Based on previous research, it can be concluded that research on comparison of acquisition
software has been done by McDown, Varol, Carvajal, Chen, but the software tested was different
from this study. The results of this study are expected to help investigators in determining the best
acquisition software so as not to leave many artifacts because it impacts on important evidence.
3. Methodology
The method used to compare the acquisition of five tools that run on Live forensics Image
Acquisition Proposed, as seen Figure 3.
This research begins with a device that lights up then the acquisition and completion stages.
In the acquisition phase, things are examined such as the use of Memory, Processing time, DLL,
Registry Key, because this will determine the artefacts left behind. Experiments performed on a
physical device by using the Laptop Intel (R) Core (TM) i3-2350M CPU @ 2.30GHz, RAM 4 GB

4. Results and Discussion
Experiments carried out at the research aims to determine the memory usage, the use of
DLL, the processing time and changes in the Registry Key when running these tools. The
acquisition process on the RAM is very important because the data must be clean of tools used
investigator.
Figure 4 shows acquisition process with tools DumpIt run via command line on windows
and then point DumpIt layout and imaging processes. The capacity of the RAM of 4862 MB and
all data on it will be recorded on the acquisition process with the file extension RAW. Memoryze
is tools acquisition and RAM usage showed in 2600k in Figure 5. It can be seen the use of RAM
on the Windows task manager. Process Explorer also shown application use of RAM and showed
in Figure 6.

Figure 7 can be seen all of the keys that are used to run the FTK Imager so that this key
will turn on the RAM which will be useful for a forensic process. Registry Key will record all log
the use of programs including access time, walking and even modify the program. Tools FTK
Imager 13.736 Kb of RAM, this is because FTK Imager multithread resulting takes a lot of RAM.
In DumpIt tools using the smallest RAM is equal to 692 Kb, this happens because DumpIt runs
on the command line so it takes up little RAM shown in Figure 8.
Acquisition tools on Figure 9 shows the time difference in the acquisition process of the
five tools, from five tools, can be seen that DumpIt has the fastest time is 184.54s compared to
other tools and Magnet RAM Capture lowest time is 220.24s. Different uses of the DLL and
change the Registry Key for running software, can be obtained Magnet RAM Capture uses the
highest DLL that is 285 to change the Registry Key for 98. At DumpIt tools using the smallest DLL
by 44 and Registry Key as 4. this makes the best DumpIt on heritage artifacts in the operating
system shown in Figure 10.
In the Table 1, are known to the software with the use of a memory with a small size that is
DumpIt, Memoryze, Belka RAM Capturer. FTK Imager on the memory usage using the highest
memory is 117 Mb, while the lowest with 10.9 Mb DumpIt. At Magnetic RAM Capture processing
time takes a lot for the acquisition of 4 Gb of RAM memory that is 220.24 s while Memoryze only
takes 184.54 s. The use of RAM Capture Key Registry Majority Magnet by using 98 keys and
DumpIt only need 4 key. RAM usage Magnet Capture DLL for use with the highest DLL 285 and
DLL little DumpIt use only 44

presents five acquisition software with a fast process, leaving little artifacts and RAM usage. The
five forensic acquisition software analyzed were FTK Imager, Memoryze, Belkasoft RAM
Capturer, Magnet RAM Capturer, DumpIt. As a result of this study, the FTK Imager left around 10
times more artifacts from DumpIt and Memoryze. Magnet RAM Capture artifacts at most, four
times more than Belkasot RAM Capturer. Software acquisition with many artifacts, namely
Capture RAM Magnet and FTK Imager, while for the fastest time is DumpIt and for software that
takes a long time, namely RAM Capture Magnet. Suggestions for future research is to compare
with hardware, other operating systems with software commonly used by digital forensics
investigators.

Forensically sound evidence processing is the key component of prosecution to convict the perpetrator. When an investigator approaches the crime scene and encounters the running system, the most essential thing to do is to capture the system's memory. Memory forensic plays a significant role in the analysis of different forensic artifacts that may not be present on the hard disk. Memory is divided into two regions, user space and kernel space. Incident responders should collect all user space and kernel space for a comprehensive forensic examination. Moreover, memory is fragile in nature, so during the evidence gathering process, the minimum contamination should be performed. Therefore, the best memory acquisition tool must be identified that can assist the forensic examiner with the thorough examination of collected evidence. In this paper, among five commonly used memory acquisition tools, an attempt was made to find the best memory acquisition tool.
... DumpIT also supports x86 and x64 based systems. As shown by Faiz and Prabowo [20], DumpIT leaves the least footprint in the memory. Therefore, it can be considered an ideal tool for Windows based memory acquisition. ...

Information technology has become an essential thing in the digital era as it is today. With the support of computer networks, information technology is used as a medium for exchanging data and information. Much information is confidential. Therefore, security is also essential. Metasploit is one of the frameworks commonly used by penetration testers to audit or test the security of a computer system legally, but it does not rule out the possibility that Metasploit can also be used for crime. For this reason, it is necessary to carry out a digital forensic process to uncover these crimes. In this study, a simulation of attacks on Windows 10 will be carried out with Metasploit. Then the digital forensics process uses live forensics techniques on computer RAM, where the computer RAM contains information about the processes running on the computer. The live forensic technique is important because information on RAM will be lost if the computer is off. This research will use FTK Imager, Dumpit, and Magnet RAM Capture as the RAM acquisition tool and Volatility as the analysis tool. The results of the research have successfully shown that the live forensics technique in RAM is able to obtain digital evidence in the form of an attacker's IP, evidence of exploits/Trojans, processes running on RAM, operating system profiles used and the location of the exploits/Trojan when executed by the victim.

Today's technology grows its roots in positive and negatives both directions. Cyber criminals are always get one step ahead then the investigator. Digital forensics in the live environment is the biggest challenge. Aquistion of live artifacts on running system needs expertise to achieve expected results. One of the most important areas where every forensicator looks into is Memory, i.e. RAM-Random Access Memory. RAM is a volatile memory which flushes when system is shut down or restart. So before shutting down the system Memory dump should be taken. It is very important aspect for carving information resided into the volatile memory.[1] Here a role of a volatile memory analysis in digital forensics and the importance of the physical memory analysis is proposed. It is very useful in real time evidence acquisition analysis. Further we have introduced some of the tools and techniques used in acquisition and analysis of memory.

.In digital forensicinvestigations, the investigators take digital evidence from computers, laptops or other electronic goods. There are many complications when a suspect or related person does not want to cooperate orhas removed digital evidence. A lot of research has been done with the goal of retrieving data from flash memory or other digital storagemediafromwhich the content has been deleted. Unfortunately, such methods cannot guarantee that all data will be recovered. Most data can only be recovered partially and sometimes not perfectly, so that some or all files cannot be opened. This paper proposes the development of a new method for the retrieval of digital evidence called theTwo-StepInjection method (TSI).It focuses on the prevention of the loss of digital evidence through the deletion of data by suspects or other parties. The advantage of this method is that the system works in secret and can be combined with other digital evidence applications that already exist, so that the accuracy and completeness of the resulting digital evidence can be improved. An experimentto test the effectiveness of the method was set up.The developed TSI system worked properlyand had a 100%success rate.

The comparison studies on random access memory (RAM) acquisition tools are either limited in metrics or the selected tools were designed to be executed in older operating systems. Therefore, this study evaluates widely used seven shareware or freeware/open source RAM acquisition forensic tools that are compatible to work with the latest 64-bit Windows operating systems. These tools' user interface capabilities, platform limitations, reporting capabilities, total execution time, shared and proprietary DLLs, modified registry keys, and invoked files during processing were compared. We observed that Windows Memory Reader and Belkasoft's Live Ram Capturer leaves the least fingerprints in memory when loaded. On the other hand, ProDiscover and FTK Imager perform poor in memory usage, processing time, DLL usage, and not-wanted artifacts introduced to the system. While Belkasoft's Live Ram Capturer is the fastest to obtain an image of the memory, Pro Discover takes the longest time to do the same job.
Conference Paper
Virtual Forensics is a new trend in the area of computer forensics. Virtualization technology paved the way for the growth of virtual forensics. VMware virtual environment provides a completely virtualized set of hardware to the guest operating system. The features of Virtual Machine make it an interesting platform to commit cyber crimes. The combination of innovative criminal techniques and advanced technologies makes the traditional techniques out-dated for detecting such crimes. This paper discusses how live acquisition can be performed to acquire virtual machine related files from the host operating system. The paper also describes how to analyze these acquired files to obtain raw data stored in various grains. The study is supported by methods that assist forensic examiners by providing valuable information from the raw data which is retrieved from various grains pointed by grain table entries.
