Computer forensics case studies


Computer forensics case studies deal with electronic crime. Digital forensics is a key component of law enforcement investigations.  Digital forensics is the study and storage of data. This includes salvaging analysis or investigation data stored in electronic devices. This kind of science is extremely efficient in analyzing digital data and finding facts in the digital format. It’s unlike any other type of investigation tool. People immediately think about solving the problem when an enterprise is breached or becomes a victim of cybercrime. True cyber professionals know that this is just the beginning. Digital police officers must undergo a rigorous process to identify, preserve, analyze, and present digital evidence. Digital forensics has developed to meet the rapid adoption of technology and how it is used for criminal activity since the 1970s.

Computer forensics case studies methods have evolved from what they were in 1980 due to the widespread use of computers in financial crime. Modern computing has created a new environment for criminal activity. Digital forensics has become a crucial tool for law enforcement to pursue and convict computer-based crimes such as cyber stalking, human exploitation, and cyber-terrorism. Computer-facilitated crimes such as data theft and illegal data breaches can also be computer-facilitated. Digital forensics detectives are also known as digital police officers.  Computer forensics case studies professionals, also known as digital police officers, can be found in law enforcement agencies or private institutions. These experts are crucial in the investigation of crime. Digital Forensics in Law EnforcementComputer forensics case studies


Specialized tools have been developed to support investigators in collecting, analyzing, and preserving evidence during criminal investigations. Any component of an enterprise system could be at risk from criminal activity, data theft, or unauthorized penetration. Forensic analysts need to examine storage media, operating systems, networks, applications, and hardware to find the source of compromise. The investigation level is determined by the mission criticality of compromised applications, systems, or networks. Following the scientific process of digital forensics is crucial when conducting a forensic investigation. This includes all phases of evidence gathering, from data collection to analysis and reporting. Investigators collect data, obtain search authority, and document the chain. They also hash and duplicate any evidence.

The examination and analysis phases are where investigators validate and perform analysis. They also reproduce the methods and results for reassurance. Reporting is crucial because it is where conclusions are reached, and expert evidence or testimony is presented. Expert testimony may also be required. This scientific process increases the chances that all evidence will be admissible in court. Human errors can happen in any organization. If they become the victim of a breach, they can immediately bring digital forensics specialists or law enforcement to assist.

Cyberattacks can affect all computer systems and devices, including mobile devices, networks, and computers. Every device type has its own intrusion requirements and evidence handling requirements. This has resulted in three distinct branches of digital forensics. Computer forensics, for example, may require the creation of a disc image to preserve evidence. Or virtual drives can be used to simulate an entire machine. Network forensics is about the analysis and monitoring of computer network traffic. Mobile devices pose unique challenges because of memory volatility. Smartphone that use low-power DRAM can lose data if they are powered off. Proper handling procedures must be followed to preserve and protect such evidence, and the documented chain of custody must also be observed.

In  Computer forensics case studies, no matter where an attack occurs, the enterprise cyber security program must have policies addressing all aspects of forensics, such as monitoring, contacting law enforcement, and reviewing forensic guidelines, policies, and procedures. These policies should consider the preservation and maintenance of evidence and any other requirements, such as accreditation in cases where cardholder data is involved and the possibility of involving outside specialists.

Digital forensics is a way to ensure the best practices are followed during evidence collection when an enterprise is breached.  Computer forensics case studies data can be stored in many different ways. Organizations should consider which storage methods they should use. Organizations must manage digital data properly and take the necessary precautions to ensure safety. Without digital forensics, evidence may go unnoticed, become compromised, and systems could remain vulnerable to further attacks. Cybercriminals will become more sophisticated, data breaches are more costly for enterprises, and digital forensics and its scientific process will allow them to bring cyber criminals to justice in a complex and fast-moving technological environment.

Computer technology is an integral part of everyday human life. It is also growing rapidly. Computer Forensics is essential in countering these computer-related crimes. Computer Forensics is the process of obtaining and analyzing digital data for use in administrative, criminal, or civil cases (Nelson et al. 2008).

Computer forensics case studies Investigations generally examine data that could be taken from hard drives or other storage devices. They follow standard policies and procedures to determine whether unauthorized access compromised the devices. Computer forensics case studies Investigators work together to investigate an incident and perform forensic analysis using various methods (e.g., static and dynamic tools) and other tools (e.g., To ensure that the organization’s computer network is secure, use ProDiscover and Encase.  Computer forensics case studies  Investigators must be knowledgeable about the laws and regulations in their country regarding computer crimes.

Computer Misuse Act 1990 (U.K.) and different computer operating systems (e.g., Windows, Linux) and network operating systems (e.g., Win NT Nelson, B., and co-authors (2008) state that there are two distinct categories of Computer Forensics Investigations. They are Private Investigations or Corporate Investigations. Government agencies will conduct public investigations, while private investigations will take place by private computer forensic teams. Since an incident occurred at a Luton-based start-up SME, this report will focus on private investigations.

 Computer forensics case studies  investigation model

Computer forensics case studies investigation is to identify and preserve pieces of evidence, extract them, and document each step. Then, analyze the pieces of evidence to determine the root cause and provide recommendations or solutions.

” Computer Forensics” is a new field with less standardization across courts and industries. Each computer forensic model focuses on a specific area, such as electronic evidence discovery or law enforcement. There is no one digital forensic investigation model that everyone has accepted. It was agreed that the framework for digital  Computer forensics case studies investigation must be flexible to support all types of incidents and new technologies. (Adam R. 2012).

Kent K. et al. (2006) created a basic model for  Computer forensics case studies investigations called the Four Step Forensics Process. This was inspired by Venter (2006), who believed anyone could conduct a digital forensics investigation. This model is flexible enough to allow an organization to choose the best model for the situation. This is why we chose this model to conduct our investigation. The figure below shows the four main processes of FSFP:

Computer Forensics Cases

Data Theft – Client and Confidential Information Breach

An international recruitment agency asked us to investigate the case of a former employee. We also had to examine the mobile phone and laptop of the employee. The company believed that the employee had sent confidential and contact information to his personal email address. He also copied many business-critical files onto his memory stick just before his departure. This information was then used to create a rival company. An investigation of his mobile phone, laptop, and memory stick revealed that he had deleted many files and confidential client database entries before resetting his computer.  Computer forensics case studies Lab detectives found digital evidence that the employee had violated his employment contract. He was then brought to court. His employers were able to take him to court to seek damages.


One senior management team member at a financial institution experienced a series of distressing events that included unsolicited emails and texts from someone they believed to be within their organization.  The computer forensics case studies Lab was commissioned to investigate and discover the evidence that could lead to identifying the people involved. Although the email headers were forged, it quickly became clear that the emails were not sent from the recipient’s organization. The messages came from a staff member at a rival financial institution who had previously worked for the client. Our investigation led to the arrest of the accused.

Impersonation & Financial Fraud

Computer forensics case studies

One of the Computer forensics case studies involved impersonation and financial fraud. After being approved for a mortgage, the client hired a lawyer to help him with the purchase of his dream home. The client met with the solicitor in her office and was provided with all the necessary paperwork. He was also instructed to pay the deposit for the house into an escrow account set up by the solicitor. From that point, they agreed to exchange email addresses. After many email exchanges, the solicitor sent the client an email requesting that the deposit be paid to a different account than the one listed in the paperwork.

It appeared that the email was from the solicitor. She included all of her usual contact details and signatures. Our client did not seem suspicious. He transferred PS55,000 to the account and called her the following day to verify that the solicitor had received his house deposit. Our client was disappointed that the solicitor had not requested a change in her bank accounts via email. An investigation by the client and the solicitor at the email address revealed that her computer was infected with a Trojan virus. A fraudster from Nigeria, Abuja, gained access to her system and impersonated the solicitor.

Invasion of privacy and domestic abuse

The case of a woman who had been a victim of domestic abuse and bullying by her husband, a senior I.T. technician specializing in computer security, was handled by us. He knew everything about hiding his identity using proxy chains and had infected his wife’s personal computer, tablet, and mobile with Trojans. The husband had an extremely fast internet connection, which allowed him to monitor the wife’s mobile, tablet, computer, and, unusually, her smart T.V. He used this information to intimidate and bully her. This was something that the wife didn’t know about for more than 4 years. She also had no I.T. skills and no idea of her husband’s spying activities.

The controlling husband made the wife feel isolated and scared by his constant domestic abuse. She became very afraid that her husband would find out about her family secrets and could end up in even more trouble. She discovered that her husband had been spying on her for years. This caused her to be extremely upset and disturbed. This only led to more abuse. She finally got the courage to confide in a friend, who convinced her to contact a computer forensics expert. We helped her and asked for all of her devices, including tablets and mobile phones. We were able to gather all the digital evidence required by the court. The police cautioned the husband for his actions, and he was later convicted of the invasion of his wife’s privacy. Some of the digital evidence we gathered was used to help her case against the husband. This led to severe court sanctions and her custody of her children.
