Best Hacking assignment help
A hacker is an individual who uses computer, networking or other skills to overcome a technical problem. The term also may refer to anyone who uses their abilities to gain unauthorized access to systems or networks in order to commit crimes. A hacker may steal data or damage property resulting in monetary or physical harm. They may also use this information to blackmail someone to get something they want, such as money or access to private information. Hackers are traditionally considered to be computer programmers who are gifted with incredible talent, devoting hours of work into connecting disparate parts of the code. The term has historically been seen as one that is tough to classify but can refer to anyone doing amazing things. However, the term is also commonly applied to individuals who use this skill for illegal or unethical purposes.
Hacker was first used in the 1960s to describe a programmer or an individual who, in an era of highly constrained computer capabilities, could increase the efficiency of computer code in a way that removed, or hacked, excess machine code instructions from a program. It has evolved over the years to refer to someone with an advanced understanding of computers, networking, programming or hardware.
How does hacking work?
Hackers can use their technical skills to exploit cybersecurity defenses so they try not to exploit them accidently. Some hackers start this way, but many others find themselves falling into the industry by testing for cybersecurity vulnerabilities or for-profit reasons like a penetration tester might. The end goal is often to gain unauthorized access to computers, networks, computing systems, mobile devices or internet of things systems. Many professional hackers use their skills to determine security holes in enterprise systems and then advise where companies should boost their security defenses to keep threat actors out.
Results can also be deleterious: Malicious hackers may steal login credentials, financial information and other types of sensitive information.
Many hackers aim to exploit either technical or social weaknesses to breach defenses. Technical weaknesses may include vulnerabilities in software or other exploitable weak spots. To exploit social weaknesses, hackers may attempt to manipulate social outcomes through false pretenses, such as impersonating a co-worker or other individual to gain financial or login information. Hackers may also use their technical skills to install dangerous malware, steal or destroy data, or disrupt an organization’s services.
Hackers of all types participate in forums to exchange hacking information and tradecraft. There are numerous hacker forums where ethical hackers can discuss or ask questions about hacking. Many of these hacker forums offer technical guides with step-by-step instructions on hacking.
Unlike the black market, the Dark Web provides a safe and legal marketplace for hackers to buy and sell hacking services.
Criminal hackers, who sometimes lack technical skills, often use scripts and other specifically designed software programs to break into corporate networks. This software may manipulate network data to gather intelligence about the workings of the target system. Scripts like these can be found on the internet and can be used by anyone, including entry-level hackers. For those with limited skills, these scripts are called “script kiddies. “Advanced malicious hackers might study these scripts and then modify them to develop new methods.
What are the different types of hackers?
In the past, the security community informally used references to hat color as a way to identify different types of hackers, usually divided into five main types. A few of these terms have been replaced to reflect cultural changes.
Ethical hackers or authorized hackers — previously known as white hat hackers — strive to operate in the public’s best interest rather than to create turmoil. Many people are hired by companies to work on their networks, hacking them in order to find and report on security vulnerabilities. These hackers are ethical hackers who use these opportunities. The security firms then help their customers mitigate security issues before criminal hackers can exploit them.
Threat actors and unauthorized hackers that were formerly known as black hat hackers, often intentionally intrude on networks with malicious intent. Cybercriminals take advantage of vulnerabilities in sensitive computer systems to steal data, spread malware or profit from ransomware. They also vandalize or otherwise damage the system so they can get your publicity. The target of a threat actor is usually a company with valuable information. They often conduct these activities using computers that they have hacked, which may include stealing data before the company can fix them or launching DDoS attacks..
Gray hat hackers fall somewhere between ethical hackers and threat actors. While the motives of gray hats are similar to those that ethical hackers have, they are more likely than threat actors to access systems without authorization. This is because they usually do not intentionally cause damage to a system & typically avoid unnecessary intrusion as well.Although they aren’t typically — or only — motivated by money, gray hat hackers may offer to fix vulnerabilities they have discovered through their own unauthorized activities rather than using their knowledge to exploit vulnerabilities for illegal profit.
Red hat hackers, are similar to ethical hackers, who intend to stop unethical attacks by threat actors. Red Hat hackers are also called eagle-eyed or vigilante hackers. While red hat hackers may have a similar intent to ethical hackers, they differ in methodology, as red hat hackers may use illegal or extreme courses of action. Often, red hat hackers will deploy cyber attacks toward the systems of threat actors.
Blue hat hackers, also known as vengeful hackers, use hacking as a social weapon. Frequently, it is used as a means for revenge against a person, employer or other organization. Hackers who post personal and confidential data online to ruin reputations or attempt to gain unauthorized access to email and social media accounts are classified as blue hats.
What are common hacking techniques?
While the technological basis of these techniques is constantly evolving to keep up with developments in cybersecurity, the following common hacking techniques are persistent:
Phishing. The criminal hacker creates a fraudulent email that appears to come from a legitimate organization and prompts the user to open it. Users are then tricked into entering their login credentials and disclosing other personal information, such as birth date, Social Security number or credit card details.
Viruses and malicious code Hackers are using techniques to inject malicious code into files on websites, in order to track user activity online.
User interface (UI) redress. This technique, also known as clickjacking, creates a fake UI and link on top of an authentic webpage and tricks the user into clicking on the link. The threat actor can then take access of the user’s computer without their knowledge.
DoS and DDoS. These techniques make it impossible for users to access their computer systems, networks, services or other information technology (IT) resources. Typically, a criminal hacker uses this technique to crash web servers, systems or networks by disrupting the normal flow of traffic.
Domain name system (DNS) cache poisoning. This technique, also known as DNS spoofing, exploits DNS clients and web servers by diverting internet traffic to fake servers.
Structured Query Language (SQL) injection. This technique adds SQL code to a web form input box in order to gain access to unauthorized resources and data.
Keylogger injection. A keylogger program has been inserted into the user’s system as malware and spies on and records keystrokes. It gives the threat actor access to: personal information, login credentials and sensitive company data
Brute-force attack. These attacks commonly use automated tools to guess various combinations of username and password until they find the correct combination.
