Typical Methods Employed by Cybercriminals for Hacking Purposes
===============================================================================
In today's digital world, hacking has become a significant concern for individuals and businesses alike. Hacking is the process of exploiting vulnerabilities to gain unauthorized access to computer, smartphone, tablet, or network systems. Here, we delve into the different types of hackers and common techniques they use.
The Different Types of Hackers
Ethical Hackers (White Hat Hackers)
Ethical hackers, also known as white hat hackers, use their skills to protect confidential information from being stolen. They employ various techniques for penetration testing and system vulnerability assessment to discover and exploit vulnerabilities before malicious actors can.
Grey Hat Hackers
Grey hat hackers might break into systems without permission, but usually without harmful intent. They often disclose the vulnerabilities they find to the system owners, but may also use the information for personal gain.
Black Hat Hackers
Black hat hackers are criminals who break into systems to steal data, cause damage, or make money illegally.
Script Kiddies
Script kiddies are inexperienced hackers who use ready-made tools or scripts developed by others.
Hacktivists
Hacktivists break into systems to support political or social causes.
Red Hat Hackers
Red hat hackers are vigilantes who go after black hat hackers using aggressive methods.
Common Hacking Techniques
Penetration Testing
Penetration testing involves simulating cyber attacks to identify vulnerabilities in a system. It consists of four main phases: reconnaissance, scanning, exploitation, and post-exploitation.
Reconnaissance
Reconnaissance involves gathering information about a target system. This can be done through passive reconnaissance (without interacting with the system) or active reconnaissance (directly interacting with the system).
Scanning
Scanning helps identify open ports and services on a network, as well as potential vulnerabilities. This can be done through network scanning or vulnerability scanning.
Exploitation
Exploitation involves using tools like Metasploit and Burp Suite to exploit identified vulnerabilities. Social engineering techniques like phishing or physical infiltration may also be used to uncover vulnerabilities that are not purely technical.
Post-Exploitation
Post-exploitation involves maintaining access to the system to understand how long an attacker could remain undetected.
Vulnerability Assessment
Vulnerability assessment is the process of identifying and prioritising vulnerabilities in a system. It consists of two main phases: automated scanning and compliance checks.
Automated Scanning
Automated scanning involves using tools to scan systems for known vulnerabilities by comparing them against databases like the Common Vulnerabilities and Exposures (CVE) list.
Compliance Checks
Compliance checks ensure that systems comply with regulatory frameworks like PCI DSS, HIPAA, and GDPR.
Real-life Examples and Wake-up Calls
The Equifax Data Breach (2017) resulted in the theft of personal data (names, Social Security numbers, birthdates) of 147 million people, making it one of the biggest identity theft risks in history. The Twitter Hack (2020) saw hackers take over high-profile Twitter accounts to promote a fake Bitcoin giveaway, serving as a major wake-up call about social media security. The Colonial Pipeline Attack (2021) forced one of the largest fuel pipelines in the U.S. to shut down due to a ransomware attack, causing gas shortages and panic buying.
Protecting Yourself from Cyberattacks
Understanding the different types of hackers and common techniques they use, such as viruses, phishing, and ransomware, can help individuals stay alert and take steps to protect their data. By being cautious online, using security tools, and keeping systems updated, individuals can reduce the risk of falling victim to cyberattacks.
