I have over five years of experience in computer forensics, working on a variety of cases including cybercrime investigations, data breaches, and internal investigations. I am proficient with tools such as EnCase, FTK, and X-Ways Forensics, and I have a strong understanding of various file systems and data recovery techniques.

To ensure the integrity of digital evidence, I always follow chain-of-custody protocols from the moment evidence is collected until it is presented in court. This includes documenting every step of evidence handling, using write-blockers to prevent data modification during acquisition, and maintaining secure storage for all evidence.

When investigating a cybercrime, I start by identifying and securing the affected systems to prevent further damage. I then collect and preserve all relevant data for analysis. This is followed by a detailed examination of the data to uncover any signs of unauthorized access, malware, or data exfiltration. Finally, I compile a thorough report with my findings and recommendations for mitigation.

I use a variety of tools for data recovery, including EnCase, FTK, and X-Ways. I also employ techniques such as keyword searches, file carving, and metadata analysis to recover deleted or hidden files. My approach depends on the specific circumstances of the case and the type of data involved.

I stay up-to-date with the latest developments by continuously engaging in professional development activities. This includes attending industry conferences and workshops, participating in online forums and professional groups, and regularly reviewing current research and publications in the field of computer forensics.

One challenging case involved a ransomware attack on a financial institution. The attackers had encrypted critical data and demanded a substantial ransom. By analyzing the network traffic and examining the affected systems, I was able to identify the malware's entry point and trace it back to a phishing email. I worked with the IT team to isolate the attack, remove the malware, and restore the data from backups. Additionally, I provided recommendations to enhance the organization's cybersecurity posture to prevent future incidents.
