The intersection of digital forensics and cyber crime: what you need to know

DFI - Part 9

Digital forensics and cybercrime are two of the most pressing issues in the modern era. The exponential growth of technology has made it possible to conduct illegal activities at an unprecedented level. The need to investigate cybercrime and provide forensic evidence has become vital to the criminal justice system. In this blog, we will explore what digital forensics and cybercrime are, their relationship, and how digital forensics help in solving cybercrime.

What is Cybercrime?

Cybercrime refers to any criminal activity that is committed using a computer or a computer network. Cybercriminals use advanced techniques to access sensitive information, steal money, and disrupt critical systems. Cybercrime can take many forms, including identity theft, phishing scams, ransomware attacks, and hacking.

Cybercrime is a global issue, that affects individuals, businesses, and governments. According to a report by Cybersecurity Ventures, cybercrime will cost the world $10.5 trillion annually by 2025, up from $3 trillion in 2015. Cybercriminals are motivated by financial gain, political objectives, or personal vendettas. Cybercrime is often difficult to detect and prosecute, as it can be committed from anywhere in the world, and the perpetrators can remain anonymous.

There are several types of cybercrime, and each type has its own characteristics and impacts. Some of the most common types of cybercrime include:

1. Hacking: Hacking involves gaining unauthorized access to a computer or network to steal or manipulate data.
2. Phishing: Phishing is a type of social engineering attack where cybercriminals use fake emails, websites, or messages to trick individuals into divulging sensitive information such as login credentials or credit card details.
3. Malware: Malware refers to malicious software that is designed to disrupt or damage digital devices and networks. Malware includes viruses, worms, Trojan horses, and ransomware.
4. Identity theft: Identity theft is a type of cybercrime where cybercriminals steal personal information such as social security numbers, credit card details, and bank account information to commit fraud.
5. Cyberstalking: Cyberstalking involves using the internet to harass, intimidate, or threaten an individual.

What is Digital Forensics?

Digital Forensics is the process of collecting, analyzing, and preserving electronic data in a manner that maintains its integrity and admissibility as evidence in a court of law. The primary objective of digital forensics is to identify, preserve, recover, analyze, and present digital evidence in a manner that is acceptable in a court of law.

Digital forensics is a process that involves several steps for collecting and analysing electronic data to identify potential evidence of criminal activity. To begin, a forensic expert collects the electronic device or devices that contain the relevant data. Next, they make an exact copy of the device to ensure that the original evidence is not destroyed or altered during the investigation. Then the investigator presents the evidence in a clear and concise manner that is admissible in a court of law.

The types of evidence that can be collected in digital forensics investigations include emails, social media posts, text messages, files, and metadata. Metadata is data that describes other data, such as the time and date a file was created or modified. Digital forensics is essential in cases of intellectual property theft, fraud, cyberstalking, cyberbullying, and cyberterrorism.

Digital forensics experts use specialized tools and techniques to examine electronic devices such as computers, smartphones, and storage media, to recover lost or deleted data, identify evidence of cybercrime, and ultimately establish the truth in a legal matter. Some of the most commonly used digital forensics tools include:

1. Encase: Encase is a digital forensics tool that is used to collect and analyze digital evidence from a wide range of devices and networks.
2. FTK: FTK is a digital forensics tool that is used to collect, analyze, and preserve digital evidence from computers and networks.
3. Autopsy: Autopsy is an open-source digital forensics tool that is used to analyze digital evidence from a wide range of devices and networks.
4. X-Ways Forensics: X-Ways Forensics is a digital forensics tool that is used to collect and analyze digital evidence from computers and networks.
5. Belkasoft: Belkasoft is a DFIR tool that provides a wide variety of options to assist the digital forensics investigation.
6. Cellebrite: Cellebrite tools are digital forensic software and hardware used to extract and analyze data from mobile devices, computers, and other digital sources.

Digital Forensics and Cybercrime: How are they related?

Digital Forensics and Cybercrime are closely related. Digital forensics is the process of collecting and analyzing electronic data to identify evidence of cybercrime. Digital forensics plays a critical role in the investigation and prosecution of cybercrime. Without digital forensics, it would be challenging to identify and prosecute cybercriminals. Cybercriminals often leave digital footprints that can be used to trace their activities, and digital forensics investigators are trained to collect and analyze these evidence.

Digital forensics can be used to investigate a range of cybercrimes, including hacking, phishing, and identity theft. For example, if a company is hacked, digital forensics investigators can examine the company’s servers and other devices to determine how the hackers gained access and what data they stole.

In cases of identity theft, digital forensics investigators can examine the victim’s computer or other devices to determine how the intruder obtained their personal information. They can also examine the thief’s computer or other devices to find evidence of the crime.

Digital forensics can also be used to investigate cyberbullying. If someone is being harassed or bullied online, digital forensics investigators can examine the messages and posts to determine who the bully is and where they are located.

Digital forensics experts use specialized tools and techniques to collect and analyze digital evidence, such as logs, emails, and metadata, to identify the source of cybercrime. Digital forensics also plays a crucial role in preventing cybercrime. By analyzing digital evidence, digital forensics experts can identify vulnerabilities in computer systems and networks, allowing businesses and governments to take preventative measures.

Conclusion

Digital Forensics and Cybercrime are complex topics that require expertise and specialized knowledge for a comprehensive understanding. As technology advances, the sophistication of cybercrime will continue to grow, making it essential to have well-trained digital forensics experts to combat this threat. In summary, digital forensics is the process of collecting and analyzing electronic data, while cybercrime refers to any criminal activity that is committed using a computer or a computer network. Digital forensics and cybercrime are closely related, with digital forensics playing a critical role in the investigation, prevention, and prosecution of cybercrime. By understanding digital forensics and cybercrime, individuals, businesses, and governments can take the necessary steps to protect themselves from this growing threat.
