Digital forensics has made it easier to solve digital crime cases in the most innovative fashion possible. Digital forensic experts deploy a host of tools and approaches to solve cases. Two of these approaches are computer and network forensics. Often, they are mistaken for one another, but are they really the same? Not quite.

What Is Computer Forensics?

Computer forensics is the investigation and analysis carried out for gathering and preserving evidence from a computing device so it is presentable in the court of law. It is a structured investigation that maintains a chain of evidence to figure out what happened and who was behind it. However, it has legal compliance guidelines that make pieces of information admissible in legal activities.

How Does It Work?

Data Collection: Digital forensic experts isolate a device to prevent any tampering. Then, a digital copy, AKA forensic image, is made. The device is locked away, so it cannot be accessed by malicious hands.

Analysis: Next, the investigators analyze the forensic image within a sterile environment. For hard drive investigations, tools like Autopsy and Wireshark are used.

Presentation: The final step is the presentation of evidence in the court. It is then used by the judges to reach a conclusion in a legal proceeding.

Computer Forensic Techniques

Reverse Steganography:

Steganography is the process of hiding important information in a digital file or a data stream. Reverse steganography is a technique used by digital forensic experts to find out whether or not the image is recovered in its original form after the extraction of data. Hashing is used to figure out similarities and differences between the original file and the copy.

Cross-Drive Analysis

In cross-drive analysis, cross-referencing and correlation are used for information found across various devices to search, analyze and preserve information that is crucial for a digital investigation.

Live Analysis

Live analysis is the process in which a device is analyzed from within the operating system while it is functioning. This analysis used volatile data, which is stored on cache or RAM.

Deleted File Recovery

This approach searches a computer system and its memory for file fragments that were once deleted but leave their traces in other places on the same machine. It is also known as file carving or data carving.

What Is Network Forensics?

Interestingly, network forensics is an offshoot of computer forensics. However, it focuses on the retrieval of information surrounding a cybercrime. Some common forensic activities include the capturing, recording, and analysis of events that have occurred on a network to establish a source of attacks. To understand the pattern of attacks, investigators must understand network protocols, email protocols, file transfer protocols, and web protocols.

Methods

• Catch Me If You Can: This method involves the capturing of all network traffic. It also guarantees that no omission of important network events takes place. It is a time-consumingprocess, and the storage efficiency tends to drop with an increase in storage volume.
• Stop, Look,and Listen: The administrators keep an eye on each data packet moving through the network, but they will only capture the ones that are suspicious. This method doesn’t need ample space, but it does need processing power.

Primary Sources

Log Files: Such files exist on active directory servers, proxy servers, web servers, intrusion detection systems, firewalls, DNS, and dynamic host control protocols. It is worth noting that logs don’t take up too much space.

Full Packet Data Capture: Full packet data capture is the direct product of the “catch it if you can” method. Bigger enterprises have bigger networks, and it can be harmful for them to keep full packet data capture for long periods.

Tools Used in Network Forensics

Email Tracker Pro:

Shows the location of the device from which the emails are sent.

Wireshark:

Captures and analyzes network traffic between different devices.

Web Historian:

Shows a record of uploaded and downloaded files on visited web pages.

Most criminals become very good at covering up their tracks and deleting all incriminating data from their devices. However, a digital forensic expert acting as a computer forensics expert witness can recover that data given a chance using the following techniques.

Disk Imaging

This is a process where a bit-by-bit copy of the entire disk being studied becomes copied onto another disk where it can be analyzed and altered without touching the original piece of evidence, keeping the original device intact.

File Carving

The process of extracting deleted or incomplete files from the image of a device through the identification of a file header, footer, or any other signature. This method is used to extract information that may seem lost forever integral to an investigation. This process can be used in situations in which deleted data fragments or files without proper metadata are extracted from the image of a device using any other signatures or patterns possible to detect them.

Unallocated Space Analysis

Unallocated space on a drive is the space where deleted files and data can be stored. Analyzing this space can help us detect, decipher, and analyze deleted files and data fragments to be able to collect any evidence necessary, such as incriminating emails, media, or more.

Data Reconstruction

In this process, pieces of data or several fragments are drawn together to make a cohesive picture and bring the data back to its original state before being deleted or corrupted. This is a criminal’s worse nightmare.

Hexadecimal Analysis

Experts in the field have a discerning eye. They can tell when something is wrong with a digital device from a mile away. That’s where hexadecimal analysis comes in. In this process, experts break down the data into the rawest form and analyze the hexadecimal codes for any patterns or signs of being tampered with. It is also used to detect metadata to make file recovery easier.

Error Checking and Repair Tools

Experts in the field also rely on the latest developed tools to detect and repair errors in corrupted files. Sometimes, we are successful in finding the lost files, but they are corrupted beyond reproach, or at least that is what we think. There is software that can repair the corruption and get most, if not all, of your data back before it could have been exploited.

Log Analysis

The system and all applications within it leave detailed logs of every action. These logs can be located and studied extensively for any lost evidence or proof needed. You can find information on events like timestamps and more that can serve as evidence in court. It is also highly useful information for extracting lost files.

Live Memory Analysis

This technique examines the volatile or live memory within the RAM to extract information such as passwords or encryption keys.

A volatile memory dump is used for offline analysis of live memory. The raw memory dump has a wealth of information often overlooked.

Conclusion

A digital forensic engineer utilizes many techniques and tools while on the job. These range from simple data recovery processes to highly sophisticated analyses to find and reconstruct data fragments. Contact us for data forensic expert and more!

As the internet, technology, and digital forensics expand, it is more important than ever for the concerned professionals to deploy the best practices to preserve digital evidence. Besides preservation techniques, it is also important to understand the various steps of digital evidence preservation and the issues that may present themselves during this process.

Critical Steps in Digital Evidence Preservation

• Make sure to keep the current state of your device the same. If the device is turned on, keep it on; if it is off, it must be kept off. Before moving forth, contact a digital forensics expert.
• Don’t charge a cell phone or a laptop if it is running low on battery. Charging the device at this crucial stage could result in data wiping or overwriting because of automatic booting.
• Never leave the device in an unsecured place. Ensure the device carrying the digital evidence isn’t left out in the open. Always document details like where the device is, who has access to it, and when it is moved from its location.
• Keep any external storage media away from the device, and do not plug it in unnecessary places. Common external storage media examples include USBs, thumb drives, and memory cards.
• Never copy anything to and from the device carrying digital evidence. You might modify the memory’s slack space by copying anything to and from the device.
• Take pictures of the device from all sides. Photograph a mobile phone or a laptop from every side to prevent tampering until the forensic experts arrive. The slightest tampering with the device could affect the evidence.
• Don’t access any pictures, files, or applications on the device. Accessing files, apps, and images on the device may overwrite the memory or lose the data completely.
• You must remember the PIN/password of the device. You will have to share the login/credentials with the forensic team for them to do their job flawlessly.
• Don’t let anyone without forensic training near the device. Only a person with formal training in digital forensics should be allowed to access the device and its information. Exposing the device to an untrained person could result in information corruption and data deletion.
• Don’t shut down the computer. Because data can be extracted from volatile memory and disk drives, it is better to put the device in hibernation mode. Until the system reboots, the device’s contents will be preserved through the hibernation mode.

How to Expedite the Process of Preserving Digital Evidence

There are two ways forensic experts acquire digital evidence. The device is seized, or a copy is made at the crime scene. Here are some points you must remember to expedite the preservation of digital evidence.

• Share passwords, authentication codes, and screen patterns.
• Share the cables, manuals, and chargers of the device.
• Forensic experts can also analyze the interactions of your device with the internet to create a comprehensive picture of the overall activity.
• You must have ownership of the device. If you don’t have the authority to share or submit the device non-voluntarily, the police will exercise their lawful power to seize it.
• Instead of giving away your gadget to forensic experts each time, it is better to share the external storage. Therefore, make sure to have the external memory storage of your phone or laptop configured.
• Make sure to back up the device regularlyand always have backup copies for future use. It will help you store important information on a different device if needed.

How to Preserve Digital Evidence

Here are three ways forensic experts preserve evidence before analyzing it.

Drive Imaging

Before analyzing a piece of evidence, forensic experts must create an image. Drive imaging is a forensic process in which the experts create an accurate bit-by-bit duplicate image of the evidence. When analyzing this image, forensic experts must remember the following things.

• Some evidence-wiped drives may contain recoverable data for forensic experts to identify.
• All the deleted files can be recovered using forensic techniques.
• Never make the mistake of performing analysis on the original file. Always use the duplicated image when analyzing evidence.

Any hardware or software that facilitates a legal image’s legal defensibility is a write blocker, which forensic experts can use to create a duplicate image of the evidence for further analysis.

Chain of Custody

When forensic experts gather media from the client, they must document each step conducted during the transfer process on the chain of custody (CoC). Chain of custody paperwork is important for the following reasons.

• CoC is evidence that the image has been in known custody since it was created.
• The slightest lapse in the CoC will nullify the legal significance of the image and the analysis.
• The gaps in procession records, like any instance where the evidence was left out in the open or an unsecured space,can create major problems.

Hash Values

When forensic experts create a copy of the evidence for analysis, cryptographic hash values like SHA1 and MD5 are generated. Hash values are important for the following reasons.

• They help verify the integrity and the authenticity of the image and help ensure that it is a replica of the original file.
• When using the replica in court, the hash values are critical. The slightest change to the evidence will create new hash values.
• When you perform any alterations, like creating or editing a new file on your computer, a new hash value will appear for that file.
• Hash values and other metadata cannot be viewed using regular file explorers. Instead, they need special software.

If the hash values on the original evidence and the image don’t match, it could raise concerns in the court. Moreover, it is a sign that the evidence has been tampered with.

Issues in Preserving Digital Evidence

Let’s look at some of the problems forensic experts encounter when preserving digital evidence.

• Legal admissibility is the biggest problem faced while preserving digital evidence. If the evidence is available in any form of digital media, it must be quarantined and placed in the CoC. The investigators can create images later.
• Evidence destruction is another major issue faced while preserving digital evidence. If the threat actors have installed an app on the server, the future analysis will depend on whether the application is still available or deleted from the system.
• Sometimes,the media is in service. If this is the case, the likelihood of evidence destruction remains high with the time that has elapsed since the incident happened.

Solid-state drives (SSDs) are storage devices that use flash memory to store data. These storage devices are unlike traditional hard disks, i.e., spinning magnetic disks. SSDs are not designed to have any moving parts and rely on a semiconductor-based memory chip to store and retrieve data.

Digital forensic experts may face some challenges when recovering data from SSDs, and yet there are becoming more and more common because of their utility. Before we discuss these challenges, let’s understand why SSDs are gaining popularity over HDDs.

SSDs Offer Several Advantages Over HDDs

Speed

SSDs are used for faster data transfer, so they are generally replacing HDDs. SSDs are also used to access files while providing improved responsiveness. The mechanical components are great for eliminating any delays in the transfer of data.

Reliability

With no moving parts, the SSD design tends to be more reliable and less prone to mechanical failure. SSDs are also known for being shock and physical impact resistant, ensuring their lifespan is more extended than HDDs.

Energy Efficiency

SSDs are also more energy efficient as they can provide data transfer without spinning a disk. On the other hand, HDDs are powered by a motor that spins and consumes energy while doing so. This traditional model is replaced by energy-efficient SSDs that can last longer and can be used with multiple devices such as laptops, smartphones, and cameras.

Compact Form Factor

SSDs are also much smaller in size, which means they can prove to be a significant design element when added to ultra-thin laptops, tablets, and portable devices while providing improved functionality.

SSDs Use In Various Applications

SSDs are used in many different applications for their ability to outperform traditional storage devices and for providing speed and reliability alongside compact design to a wide range of computing and storage applications.

Personal Computers

SSDs are most commonly used as a means for primary storage in desktops and laptops to improve overall performance. Using an SSD can ensure faster boot time, reduce software loading time and even improve the system’s responsiveness.

Enterprise Storage

Data centers and server environments can also use SSDs for their speed and for providing efficient storage solutions. The data access and processing are improved to enhance a server’s performance.

Consumer Electronics

SSDs are also used in consumer electronics such as smartphones, tablets, cameras, and gaming consoles to provide faster data transfer, smooth multimedia playback, and improved device performance.

Now that we have understood that benefits of SSDs. let’s look into the challenges that digital forensic experts often face while recovering data from these devices.

What Are Some Of The Challenges Faced By Digital Forensic Experts When Recovering Data From SSDs?

Digital forensic experts are often required to use specialized tools and techniques for recovering data from SSDs due to the special challenges that they might face. Here are some of the challenges that digital forensic experts may encounter during data recovery from solid-state drives (SSDs).

Wear Leveling

One reason SSDs have a longer lifespan is due to water leveling. This is the process of distributing data evenly across the memory cells so that there is no excessive wear on any cells. This also means that data is never stored sequentially on the SSD.

When digital forensic experts are reserving the data, they may find fragmented files, and the files have to be reconstructed for analysis if it is ever required.

Trim Command

Trim commands on SSDs provide data blocks so that some of the data cannot be used or erased. Once the trim command is executed, the data cannot be easily recovered and it’s sometimes impossible, even for digital forensic experts.

Data Remanence

The data on SSDs is often stored in different locations which poses a challenge for digital forensic experts that may find it hard to locate and recover the data, especially when there is overwriting. In this case, digital forensic experts have to deploy specialized tools and techniques for the process of data recovery.

Encryption

SSDs provide hardware-based encryption so that data is encrypted using a unique encryption key. Without this key, digital forensic experts cannot decrypt and access the data. This is another challenge that digital forensic experts might face, impeding the process of data recovery from an SSD.

Trim-Enabled Recovery

In some cases, the forensic tools that are used for data recovery from hard drives are not useful when recovering data from SSD. In this case, the file system structure must interpret the data to recover any data. Digital forensic experts may be required to use specialized tools that are more adept at handling the process of data recovery from SSDs.

Limited Write Endurance

While using an SSD, you get a limited number of write cycles until the memory cell begins to degrade. This means that if a digital forensic expert has to operate on an SSD, they can overwrite it, resulting in wear and even permanent loss of data on the SSD. This is why it is so important to write the drive only when necessary, and when all other options have been exhausted.

Solutions and Techniques Used By Digital Forensic Experts To Overcome These Hurdles

When recovering data from solid-state drives (SSD), a digital forensic expert may encounter challenges. These challenges can be overcome with a combination of techniques, tools, and solutions that have been gathered over time. These digital forensic solutions are the fruit of continuous practice and research, the implementation of methodologies surrounding SSD technologies, and research on how these technologies have evolved.

Here are some of the tried-and-true tools, techniques, and solutions that aid the data recovery process.

Acquisition and Preservation

To ensure that data recovery from the SSD is possible, digital forensic experts may focus on properly acquiring and preserving the SSD. This means using specialized tools and following the best practices for handling SSDs. The process of data recovery from SSD requires minimizing the impact on the drive as much as possible to ensure the contents are intact.

Wear Leveling and Data Recovery Tools

Digital forensic experts to use advanced wear leveling and data recovery tools when recovering data from SSDs. Thai allows them to use the data available on the SSD to also reconstruct fragmented files, recover deleted files and ensure the SSD sustains no damage during the process.

Trim Command Management

Digital forensic experts employ this technique to ensure that the data is securely retrieved during the evidence acquisition process. This allows the hardware write blocker to interact with the SSD firmware and ensure that the data is acquired and in good shape to be used.

Data Remanence Analysis

Digital forensic experts use advanced forensic techniques, including data carving and memory cell analyses, to ensure that the data, which has been overwritten, can be recovered. The residual data patterns can then be reconstructed to analyze with the help of the data remanence analysis.

Encryption Key Recovery

Encryption key recovery includes techniques such as searching for key artifacts and analyzing system memory for key remnants. These techniques can help digital forensic experts use the vulnerabilities of an encryption system to access encrypted data and recover it successfully.

Research and Collaboration

The use of firmware updates and encryption techniques can assist digital forensic experts in the process of research and collaboration with industry experts. The process of sharing knowledge, experience, and even insight into effective solutions gathered through trial and error can help the ongoing process of overcoming SSD-related issues.

The increasing use of technology is leading to new challenges in terms of security and privacy. The ethical use of digital forensics is an essential consideration as it involves gathering, preserving, and analyzing electronic data while supporting legal investigative processes.

Though digital forensics is a valuable tool when it comes to organizations’ law enforcement, it leads to critical ethical questions on how investigation needs should be balanced with the individual’s privacy concerns. This guide will focus on the importance of ethical considerations in digital forensics and how forensic experts adhere to them.

Importance Of Ethical Considerations In Digital Forensics

Investigators in digital forensic investigations extract evidence from various digital media and devices. But the extraction method unlocks a way for these professionals to intrude on the privacy of the business or an individual.

When detecting fraud, a digital forensic consultant will gather and analyze the digital evidence associated with fraud that has occurred and then present it in the courtroom to prove the convict. There are no technical or legal structures implemented to keep track of the investigation procedures to avoid encroachment of privacy.

However, the United Nations emphasizes the privacy of a user’s personal data. Due to the increasing use of digital devices, a vast volume of personal data is created.

Digital Forensics Examinations – An Overview

A digital forensic examination occurs after the computing devices are confiscated. Automated forensic software helps recover the information that is no longer there in the system because the owner removes it for obvious reasons.

These methods allow experts to link information through several sources, leading to new investigation participants whose privacy may be infringed. Moreover, lack of details when determining items that were deliberately deleted often results in mis-accusations.

The investigation procedure requires legal support to safeguard the victims’ and suspects’ data privacy during eventual legal hearings and inquiries. Lawyers must be aware of the regulatory rules that ensure data protection, while the offenders and suspects should also pay close attention to their privacy rights.

Challenges with Maintaining Privacy During an Investigation

Depending on the crime committed and the type of inquiry, laws can substantially vary and rely heavily on the procedures and techniques used by forensic consultants. This makes the legislation more complex and difficult or impossible to implement.

Considering the number of devices that most individuals possess and the volume of information or data they contain, conducting a digital investigation while preserving the users’ privacy is one of the biggest challenges that our digital forensic experts at Eclipse Forensic can address.

Avoiding Privacy Infringement

Professional digital forensic consultants will implement several methods to avoid privacy infringement of users during investigations. This not only shields users but also digital forensic experts from being guilty of violating privacy.

Falling victim to cybercrime can feel violated to allow access to your company’s devices or digital networks to forensic investigators and law enforcement. Corporations are usually concerned about how their clients’ data and other sensitive information will be used during an investigation.

Your employees, clients, and computing system users deserve to have all Personal Identifiable Information (PII) protected during a forensics investigation. After a cyberattack or breach, the data stored on your databases, computers, networks, and mobile devices is a major source of concern for business owners.

Experienced digital forensic professionals protect user data while assuring privacy via encryption and other data-hiding techniques. They also recover passwords, discover hidden data, recover deleted items, and access encrypted files to ensure privacy. By understanding data sources, storage locations, and uses, they track data access.

 

Strategies to Protect Privacy During Investigation

Some of the most effective strategies your company can implement to protect its privacy during an investigation include:

• Using redactive technology that helps redact PII from digital storage.
• Automating the process of responding to data requests in a manner that utilizes redaction for improved protection of PII, including legally binding requests such as court orders and public record requests.
• Hiring a digital forensics expert to determine any gaps in the investigation process and improve privacy.

Hiring a Digital Forensics Investigator for Privacy Protection

Not all forensic investigations involve law enforcement. You can partner with a digital forensics company for situations like:

• When you want to have an investigation conducted after a cybercrime,
• When you want to identify how data from networks, devices, and computers was misused — even when the involvement of the police is unnecessary.
• When you want to assess the current procedures and policies to identify gaps or find mistakes in your company’s security system.

If you’re concerned about how data will be gathered, managed, and stored at your organization, bring in digital forensic experts that are trained to protect your privacy.

A Digital Forensic Investigator’s Perspective

A digital forensic investigator collects, preserves, and analyzes evidence in the form of data to recreate a crime scene. The advent of several techniques and tools during a digital forensic investigation has improved the process while preventing privacy infringement to a great extent.

So you should always hire experts that have years of experience in data security and are professional enough to deal with confidential and private data of the suspects during an investigation process. Since hiding certain information can hinder the investigation process, you must partner with forensics experts that are allowed access to all kinds of data while you can rest assured that your privacy won’t be compromised.

When it comes to using the latest technology during an investigation, certain factors affecting data protection and digital forensics must be taken into account.

Other Considerations

An ethical consideration in digital forensics is the risk of privacy invasion. Investigators, in some cases, can access sensitive information without acquiring proper consent or a warrant. As a result, the individual’s or company’s right to privacy is violated. In 2016, for example, the FBI called for Apple to form a backdoor to allow access to an iPhone. But Apple viewed this as a dangerous undertaking in terms of its security and privacy.

Another issue is the risk of discrimination and bias while collecting and analyzing digital evidence. Gender and racial biases are important factors to consider in this issue. This kind of bias is likely to have serious consequences like wrongful convictions and arrests, highlighting the need for better scrutiny and reassessing digital forensics practices.

In addition to ethical concerns, reliability, and accuracy is another issue in digital forensics. With technological advancements, falsifying and manipulating digital evidence has become much easier. As a result, the credibility of a forensic investigation can be compromised.

Regardless of these challenges, digital forensics is an important tool for organizations and law enforcement. In several cases, it helps solve crimes, but companies and users must ensure that all investigations are ethically conducted. This requires these professionals to have a strong commitment to accountability, oversight, and transparency, as well as education and ongoing training for forensic investigators.

Ethical Digital Forensics Practices

One way to ensure that digital forensic practices are ethically conducted is to comply with the guidelines and standards of the industry. The American Society of Crime Laboratory Directors, for example, has developed certain standards for outlining best practices for gathering, analyzing, and managing digital evidence.

These standards ensure reliability and consistency in forensic investigations to mitigate the ethical concerns related to digital forensics. Another approach is promoting dialogue and greater collaboration between privacy advocates, forensic investigators, and other stakeholders. These groups can detect areas of concern by working collaboratively and developing solutions. This strikes a balance between investigative needs and privacy concerns. As a result, credibility and trust are built in digital forensics practices.

As more and more businesses shift their data storage and computing needs to the cloud, cybercriminals follow suit.

Cloud-based crimes such as data breaches, ransomware attacks, and identity theft are becoming increasingly common. However, investigating these crimes presents a unique set of challenges for digital forensics experts.

How Cloud Forensics Impacts User Security and Privacy

Cloud forensics plays a crucial role in ensuring user security and privacy. With more and more sensitive data being stored in the cloud, it’s essential to have measures in place to protect users from cybercriminals seeking to exploit vulnerabilities within these systems.

One of the ways cloud forensics impacts user security is through incident response. By having a system that can quickly identify and respond to potential threats, investigators can prevent or mitigate damage caused by attacks on cloud-based systems.

Another way cloud forensics impacts user privacy is by detecting unauthorized access. If someone gains access to your account without your permission, forensic tools can help track down how this happened, what information was accessed, and what steps need to be taken next.

Challenges Faced During Cloud-Based Crimes Investigation

The rise of cloud computing has presented new challenges for forensic investigators when investigating cloud-based crimes. These challenges are multifaceted, requiring specialized knowledge from the investigator.

One challenge that arises during these investigations is access to data. Cloud service providers encrypt data at rest, making accessing information difficult without proper authorization.

Additionally, physical control over hardware in the cloud environment is non-existent; investigators cannot simply seize servers like in a traditional investigation.

Another challenge faced by forensic investigators during cloud-based crime investigations is the issue of jurisdiction. Since data may be stored across multiple jurisdictions, law enforcement agencies need to work together closely to ensure compliance with legal procedures while maintaining evidentiary integrity.

A lack of standardization also presents an obstacle for investigators since no standardized methods or tools are used to collect evidence from different cloud environments. Each case must be handled uniquely and requires adaptability on behalf of forensic analysts.

Conducting investigations into crimes committed through cloud services requires specialized knowledge and expertise in digital forensics and privacy laws and regulations surrounding electronic communications.

Strategies to Implement During Cloud-Based Crimes Investigations

Cloud-based crimes are becoming a significant threat as businesses adopt cloud technology. Investigations into these types of crimes require specialized knowledge and skills in cloud forensics.

By understanding the challenges involved and implementing effective strategies during investigations, it is possible to protect user security and privacy while bringing criminals to justice.

Ultimately, protecting user security and privacy should be a top priority for everyone investigating cloud-based crimes.
