Study Notes
Understanding Hackers and Threats in Cybersecurity
- In the cybersecurity community, hackers are categorized based on their motivations and methods using a color-coded "hat" system: white-hat, black-hat, and gray-hat hackers.
- White-hat hackers are authorized attackers who identify security vulnerabilities with the intention of fixing them, while black-hat hackers are unauthorized attackers with malicious intent seeking personal gain or to inflict damage.
- Gray-hat hackers operate without proper authorization, aiming to improve security, but their unauthorized methods can be legally and ethically questionable.
- Threat actors in cybersecurity include script kiddies, low-skill hackers using pre-made hacking tools, hacktivists promoting activist goals through hacking, criminal syndicates engaging in cybercrime for financial gain, advanced persistent threats (APTs) often linked to nation-states, insiders, and competitors engaging in corporate espionage.
- Email, social media, direct access, wireless networks, removable media, cloud services, and third-party risks are key threat vectors in cybersecurity.
- Attackers use phishing and spam messages via email and social media to infiltrate networks, physically enter organizations' facilities for direct access, exploit unsecured wireless networks, spread malware using removable media, and target vulnerabilities in cloud services and third-party devices.
- Threat intelligence is a critical component of cybersecurity, providing insights into the evolving threat landscape and enabling organizations to build effective defenses and predict potential risks.
- Open Source Intelligence (OSINT) involves gathering threat intelligence from publicly available sources, while commercial services offer proprietary or closed-source intelligence, and threat feeds from various sources are integrated into an organization’s infrastructure.
- Threat intelligence is essential for staying informed about current threats and predicting potential risks, enabling organizations to build effective defenses.
- Hackers are categorized based on their motivations and methods using a color-coded "hat" system.
- Different threat actors in cybersecurity include script kiddies, hacktivists, criminal syndicates, advanced persistent threats (APTs), insiders, and competitors.
- Various threat vectors in cybersecurity include email and social media, direct access, wireless networks, removable media, cloud services, and third-party risks.
