AGENDA
Overview of Multi-Stage Network Breaches
Understanding Forensic Investigation
3 Key Tools and Techniques to Perform Forensic Analysis
Q&A with Speaker

| | |
IMPORTANCE OF COMPUTER FORENSICS PROCESS
• The investigators must follow a forensic investigation process that comply to local laws and established
precedents
• As digital evidence is fragile, a proper investigation process that ensures the integrity of evidence is
critical to prove a case in court.
• The investigators must follow a repeatable and well documented steps

| | |
EVERY CRIME LEAVES A TRAIL OF EVIDENCE!

| | |
MULTI-STAGE ATTACKS ARE MAKING NETWORK DEFENSE
DIFFICULT!
• Multi-stage attack typically includes an initial dropper file, a main payload component of the malware,
and additional modules delivered over a period of days, weeks, or more.
• IT managers are inundated with cyberattacks coming from all directions and are struggling to keep up
due to a lack of security expertise, budget and up to date technology, according to Sophos.
• Cybercriminals use multiple attack methods and payloads for maximum impact
• Cybercriminals are evolving their attack methods and often use multiple payloads to maximize profits
• Organizations that are only patching externally facing high-risk servers are left vulnerable internally
and cybercriminals are taking advantage of this and other security lapses.
• Software exploits, unpatched vulnerabilities and/or zero-day threats are top security risk
• Lack of security expertise, budget and up to date technology.

| | |
6 STAGES OF A NETWORK INTRUSION
• Reconnaissance
• Initial Exploitation
• Establish Persistence
• Install Tools
• Move Literally
• Achieve Objective

| | |
COMPUTER FORENSICS
• Set of methodological procedures and techniques
• Finding evidence related to a digital crime, to find the culprits and initiate legal action against them.
Objectives:
To gather evidence
To track and
prosecute cyber
criminals.
To minimize losses to
the organization
To protect the
organization from
similar incidents in
future
Intent of perpetrator
Cybercrime- Any illegal act that involving a computer device, network or application
Internal- Breach of Trust by disgruntled employees
External- Attackers
• Company becomes target of intrusions every 15 minutes from external source

| | |
TYPES OF FORENSICS
• Network forensics
• Email forensics
• Malware forensics
• Memory forensics
• Cell Phone forensics
• Database forensics
• Disk forensics

| | |
CYBER CRIME INVESTIGATION
• Collection of clues and forensic evidence
• There will be at least one electronic device found during the investigation.
• The electronic device found may be central to the investigation, as it could contain valuable
evidence for solving the case.
• Therefore, the information contained in this device must be investigated in the proper manner
• Process such as collection, process and analysis of data differ based on the type of the case
• Types
• Civil
• Criminal
• Administrative

| | |
RULES OF FORENSIC INVESTIGATION
• Limited access and examination of the original evidence
• Record changes made to evidence files
• Create chain of custody
• Comply with standards
• Hire professionals for analysis
• Evidence should be strictly related to incident
• Securely store evidence
• Use recognized tools for analysis

| | |
DIGITAL EVIDENCE
Digital Evidence:
Any information of probative value that is either stored or transmitted in a digital form.
Locard’s Exchange Principle- “Anyone entering a crime scene takes something of the scene with them,
and leaves something of themselves behind when they leave”
Type
Volatile
Non-Volatile

SOURCES OF POTENTIAL EVIDENCE
• Hard Drive, Thumb Drive, Memory card
• Smart card, Biometric Scanner, Digital Camera
• Routers, Hubs, Switches
• Removable storage device
• Scanners, Fax Machines, GPS

FORENSIC READINESS
Organization’s ability to make optimal use of digital evidence in a limited period of time and
with minimal investigation costs
Benefits
Fast and efficient investigation
Structured storage of evidence- reduces expense and time of investigation
Easy identification of evidence
Gives attackers less time to cover tracks

ROLES AND RESPONSIBILITIES OF FORENSIC INVESTIGATOR
• Determine extent of damage
• Recovers data of investigate value
• Gathers evidence in a forensically manner
• Ensures that evidence is not damaged
• Creates an image of original evidence without tampering to maintain integrity
• Guides officials in carrying out investigation
• Reconstructs the damaged disks or other storage devices, and uncover the information hidden on the
computer
• Analyzes evidence data found
• Prepares analysis report
• Updated organizations about various attacks and recovery techniques.
• Address issue in court

WHAT MAKES A GOOD COMPUTER FORENSIC INVESTIGATOR?
• Interviewing skills to gather much information about case
• Researching skills to know the background activities
• Patience and willingness to work long hours
• Excellent writing skills to detail findings in the report
• Strong analytical skills to find evidence and link it to suspect
• Excellent communication skills to explain findings
• Be updated with new methods and forensic technology
• Well versed in more than one computer platform
• Knowledge of various technologies, hardware, software.
• Honest, ethical and law abiding

COMPUTER FORENSIC INVESTIGATION METHODOLOGY
1. First Response
2. Search and Seizure
3. Collect evidence
4. Secure evidence
5. Data acquisition
6. Data analysis
7. Evidence assessment
8. Documentation & Reporting
9. Testing as an expert witness

3 KEY TECHNIQUES TO PERFORM FORENSIC ANALYSIS
• Preparation/Extraction
• whether there is enough information to proceed, validation of all hardware and software,
duplicates the forensic data provided in the request and verifies its integrity, If examiners get
original evidence, they need to make a working copy and guard the original's chain of custody,
tool selection
• Identification
• Examiners repeat the process of identification for each item on the Extracted Data List, check if
its out of scope
• Analysis
• In the analysis phase, examiners connect all the dots and paint a complete picture for the
requester, examiners answer questions like who, what, when, where, and how.

3 KEY TECHNIQUES TO PERFORM FORENSIC ANALYSIS
• Autopsy/the Sleuth Kit
• The Sleuth Kit is a command-line tool that performs forensic analysis of forensic images of hard
drives and smartphones. Autopsy is a GUI-based system that uses The Sleuth Kit behind the
scenes.
• EnCase
• Encase is an application that helps you to recover evidence from hard drives. It allows you to
conduct an in-depth analysis of files to collect proof like documents, pictures, etc.
• FTK Imager
• FTK Imager is a data preview and imaging tool used to acquire data (evidence) in a forensically
sound manner by creating copies of data without making changes to the original evidence
