Modern Day Computer Forensics
Introduction
Modern day computer forensics — also known as digital forensics — is the scientific process of identifying, preserving, analyzing, and presenting digital evidence in a legally best practices manner. As businesses, governments, and individuals increasingly rely on interconnected digital data systems, the importance of forensic readiness and investigative capability has never been greater.
From ransomware attacks and insider threats to civil litigation and corporate fraud, computer forensics play a critical role in uncovering the truth behind digital activity. Advanced Technology Investigations, LLC in Greensboro, NC, leads the way in this ever-changing field.

The Evolution of Computer Forensics
Computer forensics began as a niche discipline focused primarily on desktop computers and standalone storage devices. Early investigations centered on recovering deleted files, analyzing hard drives, and examining basic system logs.
Today, the field has expanded dramatically to include:
• Cloud infrastructure
• Mobile devices
• Internet of Things (IoT)
• Virtual environments
• Cryptocurrency transactions
• Artificial intelligence systems
The rise of cybercrime, particularly ransomware campaigns like REvil and DarkSide, has accelerated the demand for advanced forensic capabilities. Our Greensboro, NC digital forensic examiners are on the cutting edge of advanced technologies to take on these task.

Core Phases of Modern Digital Forensics
1. Identification
The first step is identifying potential sources of digital evidence. This may include:
• Computers and servers
• Mobile devices
• Cloud storage accounts
• Network appliances
• Removable media
• Email systems
• Software accounts. Personal or business.
Investigators must determine what data exists, where it resides, and how volatile it may be.

2. Preservation
Preservation ensures that digital evidence remains intact and unaltered. This includes:
• Creating forensic images (bit-by-bit copies)
• Calculating and verifying hash values (MD5, SHA-256)
• Maintaining chain of custody documentation
• Securing devices in controlled environments
Improper preservation can render evidence inadmissible in court.

3. Acquisition
Acquisition methods vary depending on the environment:
• Static acquisition: Imaging powered-off devices.
• Live acquisition: Capturing volatile data (RAM, active connections).
• Cloud acquisition: Collecting data via provider APIs or legal process.
• Network capture: Packet capture (PCAP) analysis.
Modern investigations often require hybrid acquisition approaches.

4. Analysis
Analysis is the most technically demanding phase. Investigators may:
• Recover deleted files
• Reconstruct timelines
• Analyze registry artifacts
• Examine browser history and cookies
• Decode encrypted containers
• Identify malware persistence mechanisms
Popular forensic platforms include:
• Magnet Forensics – Axiom
• Exterro – FTK Toolkit
• Belkasoft Forensics
• Detego Global
• EnCase Forensics
• X-Ways Forensic

5. Reporting and Presentation
The final step involves translating technical findings into clear, defensible reports. Forensic reports must:
• Be objective and unbiased with a written expert report following best practices consisting of a cover page, table of contents, device details, a list of findings, cross reference data, reference information, evidence attachments, recreation of how evidence was created when necessary, and an expert conclusion and summary, along with an affidavit of findings.
• Document methodology
• Explain findings in plain language
• Provide reference backup explanations
• Withstand cross-examination
Expert testimony often accompanies high-profile cases.
