8.3 Cybercrime and Identity Theft

Cybercrime has evolved into a complex threat in our digital age. From hacking and phishing to malware attacks, criminals exploit technology to steal data and cause harm. Understanding these threats is crucial for protecting ourselves and our digital identities.

Combating cybercrime requires a multi-faceted approach. Legislation like the CFAA and GDPR aim to protect users, while individuals can safeguard themselves through strong passwords, software updates, and cautious online behavior. Staying informed is key to digital safety.

• Cybercrime involves criminal activities carried out using computers, networked devices, or the internet
  • Hacking gains unauthorized access to computer systems or networks to steal data or cause damage
    • White hat hacking identifies vulnerabilities and improves security through ethical means
    • Black hat hacking involves malicious intent to steal data or cause harm
  • Phishing attempts to fraudulently obtain sensitive information by disguising as a trustworthy entity
    • Spear phishing targets specific individuals or organizations with tailored attacks
    • Whaling focuses on high-profile individuals such as executives or celebrities
  • Malware attacks use malicious software designed to infiltrate, damage, or gain unauthorized access to computer systems

    • Trojans disguise themselves as legitimate software, allowing attackers to gain remote access to infected systems
    • Ransomware encrypts a victim's files and demands payment for the decryption key

Methods of digital identity theft

• Social engineering manipulates individuals to divulge sensitive information or perform actions that compromise security
  • Pretexting creates a fake identity or scenario to trick victims into revealing personal information
  • Baiting entices victims with offers or rewards in exchange for sensitive information or access to systems
• Skimming captures credit card information using hidden devices attached to legitimate payment terminals or ATMs
• Malware-based theft uses malicious software to collect personal information from infected devices
  • Keyloggers record keystrokes to capture login credentials, credit card numbers, and other sensitive data
  • Spyware monitors user activity and collects personal information without the user's knowledge
• Data breaches involve unauthorized access to databases containing personal information, often due to inadequate security measures
• Synthetic identity theft creates a fictitious identity using a combination of real and fake information to open accounts or make purchases

Combating Cybercrime and Protecting Privacy

Effectiveness of cybercrime legislation

• Computer Fraud and Abuse Act (CFAA) prohibits unauthorized access to computers and networks in the U.S.
  • Criticized for broad language that can lead to over-criminalization of minor offenses
• Electronic Communications Privacy Act (ECPA) protects electronic communications from unauthorized interception in the U.S.
  • Stored Communications Act (SCA) governs the disclosure of stored electronic communications by service providers
  • Criticized as outdated and failing to adequately protect privacy in the modern digital age
• General Data Protection Regulation (GDPR) sets guidelines for the collection and processing of personal information in the EU
  • Grants individuals the right to access, correct, and delete their personal data
  • Requires companies to obtain explicit consent before collecting and processing personal information
  • Imposes significant fines for non-compliance
• California Consumer Privacy Act (CCPA) enhances privacy rights and consumer protection for California residents
  • Grants consumers the right to know what personal information is being collected and to opt-out of the sale of their data
  • Requires businesses to implement reasonable security measures to protect consumer data

Protection against online threats

• Strong password practices
  • Use long, complex passwords with a mix of uppercase and lowercase letters, numbers, and special characters
  • Avoid using the same password across multiple accounts
  • Enable two-factor authentication when available
• Regular software updates and patches
  • Install updates and patches promptly to address known vulnerabilities
  • Use antivirus and anti-malware software and keep them up to date
• Secure network connections
  • Use a virtual private network (VPN) when accessing public Wi-Fi networks
  • Ensure home Wi-Fi networks are secured with strong encryption (WPA2)
• Cautious online behavior
  • Be wary of unsolicited emails, messages, or calls requesting personal information
  • Verify the legitimacy of websites before entering sensitive information
  • Avoid clicking on suspicious links or downloading attachments from unknown sources
• Monitoring financial accounts and credit reports
  • Regularly review bank and credit card statements for unauthorized transactions
  • Monitor credit reports for signs of fraudulent activity, such as new accounts opened in your name
• Employee training and awareness
