Study Notes
Anomaly Detection
- Monitor network and system activity for anomalies that may indicate the presence of hacker tools, such as unusual process behavior, unauthorized network connections, or suspicious file modifications.
File and Process Analysis
- Conduct manual or automated analysis of files and processes on systems to identify suspicious executables, scripts, or memory-resident processes associated with hacker tools.
Forensic Artifact Analysis
- Examine system logs, registry entries, and filesystem artifacts for evidence of hacker tool usage, such as command-line history, installation logs, and configuration files.
Analyzing Hacker Tool Usage
Timestamp Analysis
- Review timestamps associated with the installation, execution, and modification of hacker tools to establish a timeline of events and identify patterns of activity.
Behavioral Analysis
- Analyze the behavior of hacker tools during execution to understand their impact on system resources, network traffic, and security posture.
Network Traffic Analysis
- Capture and analyze network traffic to and from systems suspected of hosting or communicating with hacker tools.
- Look for indicators of command-and-control communication, data exfiltration, or exploitation attempts.
Payload Analysis
- Analyze payloads generated by hacker tools, such as exploit code or malware binaries, to identify their capabilities, targets, and origins.
Session Reconstruction
- Reconstruct network sessions and communication flows between hosts to understand the sequence of events and interactions.
- Identify session initiation, data transfers, acknowledgments, and session termination to establish timelines and correlations between network activities.
Anomaly Detection
- Analyze the behavior of network protocols and endpoints to detect suspicious activities, reconnaissance attempts, or unauthorized access.
- Monitor protocol usage, session durations, data volumes, and communication patterns to identify anomalies or deviations from normal behavior.
Forensic Reconstruction
- Reconstruct network events and activities to create a forensic timeline of network-related incidents, security breaches, or cyberattacks.
- Correlate network-based evidence with other sources of digital evidence (e.g., host logs, system artifacts) to provide a comprehensive view of security incidents.
Documentation and Reporting
- Document findings, analysis steps, and forensic conclusions in detailed reports suitable for legal proceedings, incident response, or cybersecurity investigations.
Disk Forensics
- Use disk forensics tools like Autopsy, EnCase, or Sleuth Kit to examine file metadata, recover deleted files, and reconstruct file access patterns associated with intrusions.
Timeline Analysis
- Create timelines of intrusion events based on correlated data from various sources, including network traffic, system logs, memory dumps, and disk images.
- Timeline analysis helps reconstruct the sequence of actions taken by intruders, identify attack vectors, and establish a timeline of events for investigative purposes.
Artifact Analysis
- Analyze digital artifacts left behind by intruders, such as malware executables, configuration files, registry entries, or persistence mechanisms.
- Examine artifacts to identify indicators of compromise (IOCs), malware signatures, and behavioral patterns associated with known intrusion methods.
Forensic Reporting and Documentation
- Document findings, analysis steps, and investigative conclusions in detailed reports suitable for legal proceedings, incident response, or regulatory compliance.
- Reports provide a comprehensive overview of the intrusion incident, including evidence, analysis results, and recommendations for mitigating risks and enhancing security defenses.
