Study Notes
Types Of Cybercrime
- Hacking: Unauthorized access to systems or networks; includes data breaches and infiltration.
- Malware: Malicious software designed to harm, exploit, or otherwise compromise computers; includes viruses, worms, and ransomware.
- Identity Theft: Stealing personal information to impersonate someone else for fraudulent purposes.
- Phishing: Deceptive attempts to obtain sensitive information via email or messaging platforms.
- Denial of Service (DoS): Attacks aimed at making a service unavailable by overwhelming it with traffic.
- Cyberstalking: Use of the internet to harass or stalk individuals.
- Online Fraud: Includes scams such as auction fraud, credit card fraud, and Ponzi schemes.
Cybersecurity Measures
- Firewalls: Hardware or software that blocks unauthorized access to or from a network.
- Antivirus Software: Programs designed to detect, prevent, and remove malware.
- Encryption: Encoding data to prevent unauthorized access during storage or transmission.
- Multi-Factor Authentication (MFA): Security measure requiring more than one form of verification to access accounts.
- Regular Updates: Keeping software and systems updated to protect against vulnerabilities.
- Security Awareness Training: Educating users on recognizing threats and safe internet practices.
Malware Analysis
- Static Analysis: Examining malware without executing it; includes code review and file analysis.
- Dynamic Analysis: Running malware in a controlled environment to observe its behavior and effects.
- Reverse Engineering: Deconstructing malware to understand its components and functionality.
- Behavioral Analysis: Monitoring malware’s actions during execution to identify its impact and purpose.
- Indicators of Compromise (IOCs): Artifacts or patterns that indicate a breach or malware infection.
Digital Forensics
- Data Recovery: Retrieving deleted or corrupted files from storage devices.
- Chain of Custody: Maintaining the integrity of evidence collected during a forensic investigation.
- Disk Imaging: Creating a bit-by-bit copy of a storage device for analysis.
- Log Analysis: Examining system logs to trace user activity and detect unauthorized actions.
- Forensic Tools: Software used for data extraction and analysis (e.g., EnCase, FTK).
Phishing Attacks
-
Types:
- Spear Phishing: Targeted attacks aimed at specific individuals or organizations.
- Whaling: Phishing targeting high-profile individuals (e.g., executives).
- Vishing: Voice phishing using phone calls to solicit sensitive information.
- Smishing: SMS phishing that uses text messages to deceive victims.
-
Common Tactics:
- Impersonation of trusted entities (banks, service providers).
- Creating urgency to prompt immediate action (e.g., account verification).
- Use of malicious links or attachments to deliver malware.
-
Prevention:
- User education to recognize suspicious messages.
- Verification of requests through official channels.
- Use of spam filters and security software.
Types Of Cybercrime
- Hacking involves unauthorized access to systems, leading to data breaches and network infiltration.
- Malware encompasses malicious software such as viruses, worms, and ransomware aimed at compromising computer systems.
- Identity theft occurs when an attacker steals personal information to impersonate a victim for fraudulent gains.
- Phishing attempts to deceive individuals into revealing sensitive information through emails or messaging.
- Denial of Service (DoS) attacks overload a service with traffic, rendering it inaccessible to legitimate users.
- Cyberstalking utilizes online platforms to harass or intimidate individuals continuously.
- Online fraud includes various scams, such as auction fraud, credit card fraud, and Ponzi schemes.

- Behavioral Analysis monitors the actions and effects of malware during execution to determine its purpose.
- Indicators of Compromise (IOCs) are specific patterns or artifacts that signify a potential breach or infection.
Digital Forensics
- Data Recovery techniques retrieve deleted or corrupted files, essential for retrieving lost information.
- Chain of Custody is vital for maintaining the integrity of evidence during investigations to ensure its validity in court.
- Disk Imaging captures a complete bit-by-bit copy of storage devices, facilitating further analysis without altering the original data.
- Log Analysis involves examining system logs to trace activities and detect unauthorized usage.
- Forensic Tools, such as EnCase and FTK, assist in data extraction and comprehensive analysis of digital evidence.
Phishing Attacks
- Spear Phishing targets specific individuals or organizations for personalized attacks.
- Whaling involves phishing attempts focused on high-profile individuals like executives or decision-makers.
- Vishing employs voice calls to trick victims into providing sensitive information.
- Smishing uses SMS text messages to engage users in fraudulent activities.
- Common phishing tactics include impersonation of reputable entities, creating urgency for immediate responses, and deploying malicious links to deliver malware.
- Prevention strategies involve educating users to recognize suspicious messages, verifying requests through official channels, and utilizing spam filters and security software.
