Study Notes

Cybersecurity Threats and Actors

Cybersecurity threats are often posed by individuals or groups known as threat actors.
Black hat hackers typically aim for illicit profit, personal gain, or to exploit vulnerabilities for malicious purposes.
Attack vectors represent the methods used by threat actors to gain unauthorized access to systems, such as phishing or malware.

Characteristics and Motivations of Hackers

Black hat organizations often engage in illegal activities, focusing on breach and exploitation without ethical considerations.
Black hat hackers may attempt to persuade victims into installing malware or divulging sensitive information through social engineering tactics.
Threat actors can be categorized into several groups, including white hat, black hat, and gray hat hackers, based on their motives and activities.

Penetration Testing

The main objective of penetration testing is to identify security weaknesses before they can be exploited by malicious actors.
Reconnaissance and research in penetration testing involve gathering intelligence about the target to plan an effective testing strategy.

Distraction Techniques and Tools

White hat hackers create decoy systems known as honeypots to distract cybercriminals and study their methods.
A honeypot serves the purpose of mimicking vulnerable systems to gather intelligence on potential attacks.

Gray Hat Hackers

Gray hat hackers often operate in a morally ambiguous area, sometimes probing systems without permission to highlight security flaws.
Upon discovering vulnerabilities, gray hat hackers may inform the affected parties to secure the systems, though they may not always have authorization.

Network Scanning and Discovery Tools

The Nmap port scan discovers open ports and services available on a target system, aiding in vulnerability assessments.
TheHarvester is utilized for gathering email accounts and domain/subdomain names for reconnaissance.
The nslookup command is employed to query DNS records to troubleshoot or obtain domain information.
The main goal of service discovery is to identify the services running on open ports to assess their security.
Nmap Netstat helps analyze active connections and listening ports on devices.
Dnsenum automates DNS enumeration to gather intelligence about a target's domains and subdomains.

Rootkits and IoT Attacks

A primary goal of an attacker using a rootkit is to gain persistent access while hiding their presence in the system.
IoT attacks are gaining traction due to the proliferation of connected devices with inadequate security.
Common results of a rootkit attack include loss of data integrity, unauthorized monitoring, and overall system compromise.
An attacker can achieve deep access or remote control of compromised systems using rootkits.
Common targets of IoT attacks include smart appliances, cameras, and medical devices.

Threat Hunting and Team Dynamics

The primary goal of threat hunting in a network is to proactively identify and neutralize threats before they materialize into actual attacks.
The penetration testing process is designed to assess and improve an organization's security posture through simulated attacks.
In red team/blue team exercises, red teams conduct simulated attacks to test defenses, while blue teams focus on detection and protection strategies.
The key distinction between social engineering and technical hacking lies in social engineering relying on human manipulation, while technical hacking uses software and hardware vulnerabilities.
The final phase of the penetration testing process typically involves reporting findings and providing remediation recommendations.
The blue team’s primary goal in a red team/blue team exercise is to defend systems and improve the organization's incident response capabilities.
