Study Notes
Unit 2: Cybercrime
- Agenda
- Cybercrime organization (2.1)
- Main attack vectors (2.2)
- Classification of cyber threats and cybercrimes (2.3)
- Agencies for combating cybercrime (2.4)
- SOC/CERT/CSIRT concept and major agencies (2.5)
- What is Cybercrime?
- Criminal activity targeting or using computers, networks, or devices
- Primarily for financial gain, but occasionally due to political or personal motives
- Committed by organized individuals with advanced skills, or novice hackers
- Types of Cybercrime
- Email and Internet fraud
- Identity fraud (stealing and using personal information)
- Theft of financial/card payment data
- Theft and sale of corporate data
- Cyber-extortion (demanding money to prevent attacks)
- Ransomware attacks (a type of cyber-extortion)
- Cryptojacking (mining cryptocurrency using resources not owned)
- Cyber espionage (accessing government or company data)
- Cybercrime that targets computers
- Involves viruses and malware
- Used to damage devices, stop them from working, delete data
- Denial-of-Service (DoS) attack (stops users using a machine or network, or prevents a business from providing a service to customers)
- Can be used to spread malware, illegal information, or illegal images
- Distributed Denial-of-Service (DDoS) attack
- Similar to a DoS but uses numerous compromised computers
- Malware Attacks:
- Attack where a computer system or network is infected with malware
- Used by cybercriminals for various purposes, including stealing data, carrying out other crimes, damaging data
- WannaCry ransomware attack (2017)
- Global cybercrime
- Targeted a vulnerability in Microsoft Windows on 230,000 computers across 150 countries
- Users were locked out of their files and demanded a Bitcoin ransom
- Estimated to have caused $4 billion in financial losses
- Phishing
- Spam emails or other communication to trick recipients
- Objective is to perform actions that undermine security
- Can contain infected attachments or malicious links to websites
- Often used to obtain confidential information
- Main attack vectors
- Attack surface: Sum of points on networks where unauthorized users can manipulate, extract data
- Attack vectors: Methods used to breach the network, such as weak and default passwords, phishing, social engineering, etc.
- Security Breach
- Any incident where sensitive data is accessed by unauthorized parties
- Incidents include DDoS attacks, Bitcoin mining and others
- Data breaches are most common but not all security incidents involve data theft.
- 8 Common Cyber Attack Vectors and How to Avoid:
- Compromised Credentials:
- Phishing attacks can expose user credentials
- Stolen/lost credentials can allow intruders access
- Weak and Stolen Credentials:
- Weak passwords allow attacker access
- Attackers can steal and exploit credentials
- Malicious Insiders:
- Unhappy employees can expose company information/exploit vulnerabilities
- Missing / Poor Encryption:
- Sensitive data is vulnerable without adequate encryption
- Misconfiguration:
- Default usernames & passwords, enabled setup pages may create vulnerabilities
- Attackers can take advantage of these
- Ransomware:
- Users unable to access their data until a ransom is paid
- Phishing:
- Deception to gain sensitive user information
- Compromised Credentials:
- Trust Relationships:
- A trust relationship exists between two domains or users
- A breach can allow attacker access
- SOC/CERT/CSIRT
- SOC (Security Operations Center)
- Manages security incidents
- Tracks activity on a system and notifies CSIRT of abnormalities
- Uses SIEM (security incident and event manager) Centralizes and correlates log data
- CERT (Computer Emergency Response Team)
- Responds to security incidents within an organization
- CSIRT (Community Emergency Response Team)
- Responds to security incidents within community.
- SOC (Security Operations Center)
- Cybercrime Classification (Additional note)
- Detailed taxonomy of threats
- Used for better threat identification and prevention
