Study Notes
Digital Forensics
- Recovers and analyzes data from digital devices (desktops, notebooks, tablets, smartphones)
- Is closely related to Cyber Forensics
Cyber Forensics
- Focuses on detecting and investigating cybercrimes
- Gathers and analyzes evidence within the cyber space
History of Forensics
- 1835: Henry Goddard uses physical analysis to connect a bullet to a murder weapon
- 1836: James Marsh develops a chemical test to detect arsenic, used in a murder trial
- 1930: Karl Landsteiner classifies human blood groups, earning him the Nobel Prize
- 1892: Sir Francis Galton establishes a system for classifying fingerprints
- 1984: The FBI establishes the Magnetic Media Program, later renamed to Computer Analysis and Response Team (CART), marking the beginning of computer forensics
- 1988: The International Association of Computer Investigative Specialists (IACIS) is formed, dedicated to training and certifying professionals in computer forensics
- 1995: The International Organization on Computer Evidence (IOCE) is formed
- 1997: G8 (Group of Eight Industrialized Nations) mandates training for law enforcement to address high-tech crimes
- 1998: The first INTERPOL Forensic Science Symposium is held
- 2000: The first FBI Regional Computer Forensic Laboratory is established
Cyberforensics Stages (AAEP)
- Acquire: Identification and preservation of digital evidence
- Analyze: Technical analysis of the evidence
- Evaluate: Legal interpretation and assessment of the evidence by lawyers
- Present: Presenting digital evidence in a legally acceptable manner for legal proceedings
OSSTMM (Open-Source Security Testing Methodology Manual)
- A peer-reviewed security auditing methodology for assessing against regulatory and industry requirements
- Primarily developed for penetration testing, security analysis, and operational security assessments
Cyberforensics Usage
- Intellectual Property Theft
- Industrial Espionage
- Employment Disputes
- Fraud Investigations
- Forgeries
- Bankruptcy Investigations
- Inappropriate Email and Internet Use in the Workplace
- Regulatory Compliance
Autopsy
- Open-source forensics platform used by professionals in law enforcement, national security, litigation support, and corporate investigations
- Runs on Linux, Windows, and Mac
File Carving
- Recovering hard drive data and deleted files using tools like TestDisk
Forensic Carving Tools
- MagicRescue: Identifies files using magic bytes (file patterns) and recovers data from corrupted drives or partitions
- Scalpel: A fast file carver that uses header and footer definitions to extract files from image files or raw device files
- Scrounge-NTFS: Recovers data for NTFS filesystems by rebuilding the directory structure from hard disk blocks
Forensic Imaging
- The process of making an exact copy of digital storage media to preserve its contents and structure for later analysis
Forensic Imaging Tool
- Guymager: A forensic imager supporting different image file formats and designed for fast, user-friendly operation
Python for Cyberforensics
- Python is a programming language known for its simplicity, readability, and versatility. It is widely used in cyberforensics for various tasks.
Python's Advantages
- Ease of Use: Python's simple syntax and abundance of libraries make it easy to learn and apply.
- Productivity: Python's concise nature allows developers to write code quickly and efficiently.
- Readability: Python's clear and structured syntax makes it easy to understand and maintain code.
- Natural Language Toolkit: Provides tools for processing and analyzing natural language data.
-
AI Processing: Python facilitates both symbolic and statistical AI processing:
- Symbolic: Uses Python's built-in data types for strings, lists, and more.
- Statistical: Leverages Python's strong numeric processing capabilities for matrix operations, probability, and machine learning code.
Python Basics
- Whitespace Significance: Indentation and newlines are crucial in Python for defining code blocks.
- Comments: Begin comments with '#' (hash symbol). Documentation strings, used as the first line of functions and classes, are valuable for documentation and tool integration.
Python Data Types
- Dynamic Typing: Python determines data types automatically during execution, but enforces data type compatibility.
- Strong Typing: While Python is dynamic, it still enforces data type consistency after determining the type.
Python Naming Conventions
- Names are case-sensitive and cannot start with a number. They can contain letters, numbers, and underscores.
Python Interactive Shell
- IDLE (GUI) Provides a graphical environment for interacting with Python.
- Python (command line): Provides command-line access to the Python interpreter.
Python as a Calculator
- The interpreter acts as a calculator, executing basic arithmetic expressions directly.
Lists:
- Python uses lists as a versatile data structure for storing collections of items. They are written as comma-separated values enclosed in square brackets.
Python Challenges for Cyberforensics
- Task Automation: Automating file analysis, comparison, creation, and other cyberforensics tasks using Python scripts.
- Script Files: Cyberforensic personnel can write scripts to accept arguments and execute specific tasks.
Argument Parsing
- The
argparsemodule in Python creates user-friendly command-line interfaces for scripts, enabling them to accept arguments.
Forensic Carving
- Forensic carving techniques involve identifying and extracting specific patterns (like file signatures) from data to recover files, even if they are deleted or fragmented.
Forensic Imaging
- Forensic imaging involves creating an exact copy of digital storage media to preserve its contents for analysis.
