Digital evidence plays a pivotal role in modern investigations, from criminal cases to corporate fraud. However, the integrity of this evidence is crucial for its use in legal proceedings. Mishandling digital evidence can lead to contamination, alteration, or even the complete loss of critical information. In this blog, we’ll explore some of the most common mistakes in digital evidence handling and how they can be avoided, ensuring that investigations proceed with the utmost professionalism and accuracy.

The Importance of Digital Evidence

In today’s digital age, almost every crime leaves behind some form of digital footprint. From emails, text messages, and social media activity to location data, financial transactions, and device logs, the range of digital evidence that can be used in investigations is vast. This makes the role of digital forensic services vital. A digital forensic expert is trained to collect, analyze, and preserve this evidence in a manner that maintains its integrity, ensuring that it is admissible in court.

However, the process is delicate. Even a small mistake can compromise the evidence, resulting in a loss of vital information, wrongful accusations, or the dismissal of a case. Understanding the common mistakes in digital evidence handling is critical for anyone involved in an investigation, be it law enforcement, legal teams, or private companies.

1. Failure to Properly Secure the Digital Evidence

One of the most fundamental mistakes in handling digital evidence is failing to secure it immediately upon discovery. If devices such as computers, smartphones, or storage media are left unsecured, there is a significant risk that data could be altered, deleted, or overwritten.

For example, leaving a computer powered on or allowing access to a smartphone without taking proper precautions can lead to the automatic syncing of data or updates that could compromise the evidence. In a case where time is of the essence, securing the device should be one of the first steps.

2. Not Using Write Protection Tools

When dealing with physical digital evidence like hard drives, USB drives, or SD cards, it’s crucial to use write protection tools to prevent data alteration. A digital forensic expert knows that data can be easily overwritten or corrupted when files are modified, even by simply opening them on a computer.

Failing to use write protection devices or software when acquiring data from digital media can render evidence inadmissible. In many cases, investigators mistakenly assume that copying data from a device won’t alter the original, but this is not true unless proper forensic tools are used.

3. Inadequate Documentation and Chain of Custody

The chain of custody refers to the documentation process that tracks the handling, storage, and transfer of evidence from the moment it is collected until it is presented in court. A digital forensic expert ensures that every action taken with the evidence is logged and that it is clear who has had access to the evidence and when.

Failing to maintain a proper chain of custody is one of the most dangerous mistakes in digital evidence handling. Without adequate documentation, there may be doubts about the integrity of the evidence, which could lead to its inadmissibility in court. Investigators should ensure that every step, from collection to analysis, is meticulously recorded.

4. Improper Storage of Digital Evidence

Storage conditions can impact the integrity of digital evidence. Whether it’s physical media like hard drives or mobile devices, improper storage can lead to damage or loss of data. High humidity, exposure to extreme temperatures, or physical shock can all result in data corruption or hardware failure.

Digital evidence should be stored in conditions that protect it from environmental factors. Additionally, physical security is paramount—devices should be stored in locked, access-controlled locations to prevent tampering or unauthorized access. Forensic experts understand the importance of these measures and follow strict protocols to ensure that the evidence remains safe and intact.

5. Failure to Use Proper Forensic Tools and Techniques

The digital forensics field is complex, requiring specialized software and methodologies to extract and analyze data without compromising its integrity. Using improper tools or techniques is a common mistake in digital evidence handling.

For example, extracting data from a damaged or encrypted device without the proper tools can result in corrupted data or incomplete analysis. Digital forensic services employ state-of-the-art software and proven methodologies that ensure all evidence is recovered, preserved, and analyzed correctly. Without these tools, investigators may miss critical data or fail to capture important evidence.

6. Neglecting to Handle Cloud Data Properly

Cloud storage services such as Google Drive, Dropbox, and iCloud are increasingly being used to store sensitive data. When dealing with cloud-based evidence, investigators must ensure that proper steps are taken to acquire and preserve this data, including obtaining proper access rights or legal warrants.

Failing to handle cloud data properly can lead to incomplete evidence collection or legal challenges regarding the admissibility of this evidence. A digital forensic expert is trained to follow specific procedures for extracting cloud-based data, ensuring it is preserved without compromise.

7. Overlooking Data from Non-Traditional Devices

Many investigators focus primarily on computers and smartphones, but digital evidence can exist on many other devices, such as smartwatches, routers, gaming consoles, and even IoT (Internet of Things) devices. These non-traditional devices often contain valuable evidence that could make or break an investigation.

For instance, a smart home device like a thermostat or a security camera may contain data on user behavior, location, or interactions. Similarly, gaming consoles may hold digital records of communications or activities that could provide insight into a suspect’s movements or intentions.

Ignoring these non-traditional devices can lead to overlooked evidence. Digital forensic experts are trained to consider all potential sources of digital evidence in their investigations, ensuring no stone is left unturned.

8. Inadequate Backup and Preservation of Evidence

Digital evidence can be vulnerable to loss or damage during the analysis phase if not properly backed up. An investigator might perform a forensic analysis on a device without creating a backup of the original data, leaving no way to recover the evidence if something goes wrong during analysis.

To prevent this, all digital evidence should be duplicated and backed up before analysis begins. Creating multiple copies of the evidence and storing them in different secure locations is standard practice.

9. Lack of Proper Training and Awareness

Digital forensics is a highly specialized field, and those involved in the process must be adequately trained. Law enforcement officers, legal professionals, and even corporate security teams should be aware of the best practices for handling digital evidence.

Without proper training, individuals may unintentionally commit mistakes, such as using the wrong forensic tools, improperly securing evidence, or failing to maintain proper documentation. Ensuring that all personnel involved in evidence handling receive proper training can prevent many of these issues.

Conclusion

Handling digital evidence is a delicate process that demands meticulous care and attention to detail. The common mistakes in digital evidence handling outlined in this blog highlight the need for thorough, well-documented procedures to ensure that evidence remains intact and legally viable.

There are various sources to gather electronic evidence. These sources include mobile phones, the Internet of Things, remote storage devices, and basically every other computerized system.

Importance of Digital Forensics

Usually, digital forensics is thought to be limited to digital and computerized environments. However, it has a bigger impact on society. Because computers and cell phones have become an integral part of our day-to-day life, digital evidence is critical to solving legal issues and criminal cases in the digital and the physical world.

All the connected devices generate big amounts of data. Many of them tend to log all the actions performed by the users, as well as the autonomy performed on the device, like data transfers and network connections. This includes mobile phones, cars, routers, traffic lights, personal computers, and other devices within private and public spheres.

In digital investigations, digital evidence is used for the following reasons.

Network Breaches and Data Theft

Digital forensics helps us understand how a breach happened and who was behind it.

Identity Theft and Online Fraud

It is also used to understand the impact of a breach on an organization and its customers.

Murder, Assault, Burglary, and Other Serious Crimes

Digital forensics best practices are used to gather digital evidence from computers, cars, and mobile phones from the vicinity of the crime.

White Collar Crimes

Digital forensics also detects perpetrators in white-collar crimes like extortion, embezzlement, and corporate fraud.

On an organizational level, digital forensics is used for investigating physical security incidents and the ones related to cybersecurity. Digital forensics is commonly used as part of the incident response process.

It detects a breach that occurred, the root cause of the breach, its impacts, and the people perpetrating the breach. It eradicates any future threats, thus allowing legal teams and law enforcement professionals to carry out their duties.

To utilize digital forensics, companies should manage their logs centrally and other digital evidence. They must also ensure they retain them for as long as possible while protecting them from tampering, accidental loss, or malicious attacks.

What Is a Digital Risk?

Most companies use complex supply chains that include software vendors, partners, and customers. As a result, they expose their digital assets to potential attacks.

They also leverage complicated IT environments, including mobile end-points and on-premises end-points, cloud-native containers, and cloud-based technologies, thus creating new attack surfaces.

Digital risks fall into the following categories:

Cybersecurity Risks

These attacks are aimed at sensitive information or systems and use them for malicious activities like sabotage or extortion.

Compliance Risk

Organizations face these risks in a regulated environment through the use of technology. For example, some technologies can violate the requirements of data privacy. They might also have a security control needed by security standards.

Identity Risks

These attacks aim to steal credentials or take over various accounts. These risks threaten the safety of an organization’s user accounts and those it manages on its customers’ behalf.

Third-Party Risks

Such risks arise when companies outsource activities to outsiders or third-party vendors. These risks include intellectual property vulnerabilities, data, operational/financial/customer information, and other important information shared with third parties.

Branches of Digital Forensics

Computer Forensics

Computer forensics deals with digital storage evidence. It also involves digital data for identifying, preserving, recovering, and analyzing facts and opinions on the available information.

Mobile Device Forensics

Mobile forensics revolves around recovering digital evidence from mobile devices. It includes investigating devices with internal memory and communication functionality, like mobile phones, tablets, PDA devices, and GPS devices.

Network Forensics

This field of digital forensics is responsible for monitoring, registering, and analyzing network activities. Network data is volatile, and once transmitted, it vanishes, thus establishing the proactiveness of the investigation process.

Forensic Data Analysis

Forensic data analysis examines structured data found in databases and application systems in a financial crime context. It also detects and analyzes patterns of fraudulent activities.

Database Forensics

Database forensics involves the investigation of database access. Database forensics can be used to identify database transactions that allude to fraud.

Alternatively, database forensics can also be used for timestamping an updated row time in a relational database. Such investigations aim to test and inspect a database’s validity and verify a user’s actions.

Steps in Digital Forensics

Collection

This stage revolves around the acquisition of digital evidence through phones, hard drives, computers, and other digital assets. While collecting data, it is important to make sure that no part of the data is damaged or lost. Luckily, data loss can be prevented by creating copies of storage media or by creating images of the original evidence.

Examining Evidence

This stage includes the identification and extraction of data. This stage can be broken down into three steps; preparation, identification, and extraction. Before extracting data, you can choose between working on a live or a dead system.

For example, you can either use a laptop or connect a hard drive to a PC. At the identification stage, you need to decide which pieces of data are important to the investigation. For example, a warrant may limit an investigation to a specific piece of data.

Analysis

This phase involves collecting data for proving or disproving cases built by examiners. Here are some questions examiners must answer for relevant data items.

• Who created the data?
• Who edited it?
• What was the data creation process?
• When was data created?

Besides supplying the above information, examiners also need to determine how this information relates to a specific case.

Reporting

The reporting phase includes synthesizing data and analysis into formats that make sense to the common man. Such reports are important as they help convey information for all the stakeholders to understand.

Digital Forensics Techniques

Reverse Steganography

Cybercriminals use steganography to hide data in digital files, streams, and messages. Reverse Steganography is a process used to find data hashing inside a file. When inspected through an image of a digital file, hidden information may not appear suspicious. However, this hidden information does change the underlying string of data that represents the image.

Stochastic Forensics

Stochastic Forensics helps analyze and reconstruct digital activities that don’t produce digital artifacts. Digital artifacts are unintended data alterations that occur because of digital processes. A text file is a digital artifact that contains clues alluding to a digital crime like file attribute changes or data theft. Stochastic Forensics helps in investigating data breaches that result from insider threats that don’t leave behind any digital artifacts.

Live Analysis

Live analysis takes place within the operating system when a device is running. It involves the usage of system tools for finding, analyzing, and extracting volatile data that is typically stored in cache or RAM. In live analysis, the device is kept in a forensic lab to properly maintain the chain of custody.

Cross Drive Analysis

Cross-drive analysis, AKA anomaly detection, provides contact for the investigation by finding similarities. Such similarities are used as a baseline for detecting suspicious events. The process involves the correlation and cross-referencing of information systems across various drives for finding, analyzing, and preserving any information that is relevant to the investigation.

Deleted File Recovery

Also known as file carving or data carving is a technique used for recovering deleted files. In this process, a computer is searched for file fragments that are partially deleted in one place but leave traces on the machine elsewhere.

DFIR: Digital Forensics and Incident Response

DFIR is a field of cybersecurity that combines incident response with digital forensics. Its purpose is the identification, investigation, and remediation of cyberattacks. It reduces the scope of attacks and helps return to normal day-to-day operations. Some of its advantages are as follows.

Consistency

By integrating digital forensics with incident response, we can create a consistent process for the evaluation and investigation of incidents. It helps understand the threat landscape that is relevant to a case, which strengthens the security procedures against existing risks.

Quick Incident Response

Digital forensics provides information to your incident response process, which speeds it up and allows you to respond to threats quickly and accurately. It also minimizes the scope of attacks, prevents data theft, minimizes data loss, and prevents reputational damage.

The term, “Forensics”, includes many individual disciplines and fields of investigation. What they all share is the seeking of what is true concerning the object of each of those investigations. The results forensic examiners get come after meticulous examination of data and equally often, lead to further investigation involving other forensic disciplines. For example: recovering data from a cell phone would originate in a Digital or Mobile Device forensic platform. But, if a video is the target from that phone, it may need Forensic Video enhancement/analysis, it may need to isolate individual video frames for Forensic Image enhancement/analysis or it may need to have Forensic Audio enhancement so that voices can be clarified and understood.
