Hackers have often been misrepresented as criminals, with criminals taking information or flooding websites with so much traffic that it causes their closure. In reality, however, hackers come from many backgrounds and specialize in various fields.
Hacktivists, on the other hand, may seek market advantage through corporate espionage; while others – known as corporate spies or corporate espions – seek to gain one.
Methods
Hackers employ multiple means to breach systems and steal data. One such strategy is phishing scams that lure victims into opening attachments or forwarding private information to malicious parties. Once there, hackers gain entry to networks and can gain access to sensitive files or disrupt business operations as part of an attack campaign.
Hacking methods involve altering software and applications to gain entry into a system, including altering Uniform Resource Identifiers, insecure communication channels and cross-site scripting. Hackers also sometimes utilize hardware infected with malware such as USB sticks to spread throughout networks with the goal of gaining personal information for themselves or to steal personal details from individuals.
Denial of service (DoS) attacks are another popular tactic used by hackers. DoS attacks work by flooding websites with so much traffic that they shut down, creating publicity or blackmailing companies for ransom or financial loss; hackers who utilize such methods are known as “black hats”.
Hackers can be avoided through taking proactive measures. Tools like Acunetix exist to detect and protect against these threats; however, for maximum success it’s crucial for businesses to have a dedicated security department capable of keeping up with cyber and system attacks.
Tools
Hackers utilize various hacking tools to exploit vulnerabilities on computers, web apps and networks. Hacking tools range from free or paid solutions such as malware or phishing software to penetration testing solutions and beyond – and hackers may even employ special hardware in their attacks.
Early hackers were often part of MIT’s Tech Model Railroad Club, where they would modify high-tech train sets in order to improve their functions and extend operating capacities. Later, IBM 704 computers became more widely available, prompting more experimentation as mods were made to perform new tasks or expand operating capacities. When computers became widely accessible during the 1980s, hackers saw opportunities arising; one group known as Phreakers exploited operational characteristics within telephone switching networks to dupe call centers and make free long distance calls.
Hacking has long been associated with cybercriminals who exploit personal and corporate data for financial gain or the thrill of breaking into systems for other reasons – be it financial gain or recognition through social media of their exploits. But today many more people associate hacking with individuals looking for challenges or social media recognition for their exploits than with hackers themselves.
Important to realize is that not all hackers are criminals; some can conduct hacking for legitimate reasons such as testing security or discovering weaknesses – a form known as white hat hacking (or ethical hacking). Such techniques can help organizations improve their cybersecurity.
Techniques
Hacking refers to any use of computers to gain entry to other computing systems illegally for financial gain, information gathering (spying), or disrupting data-related activities. Hackers may employ technical expertise as well as individuals without technical training known as “script kiddies” to exploit other computers’ vulnerability to attack. Some of the largest data breaches began with phishing scams that encrypted sensitive data before spreading across networks of computers.
Hacking involves several techniques, including reconnaissance, scanning and exploiting. Reconnaissance is the initial stage in any successful hacking methodology and involves gathering as much data about an objective machine or organization as possible – such as passwords, details on employees or any other relevant details – using tools such as network mappers, dialers, sweepers or port scanners.
Enumeration is another hacking technique used by attackers to identify vulnerabilities in target systems. This can be accomplished through brute force attacks or social engineering attempts at guessing passwords; brute force attacks; social engineering tactics or using tools such as Metasploit or Nmap for vulnerability scanning.
One of the most prevalent hacking techniques, known as SQL injection, targets vulnerable websites with poorly configured SQL databases. Hackers then inject code into text fields on these websites that allows them to gain access or take control of information or take over the site – something particularly damaging for small businesses that cannot pay a ransom in exchange for their data being returned.
Skills
Hackers employ skills such as programming, computer networking and information security. Hackers possess an inquisitive and creative spirit – looking at existing systems in order to find flaws they can manipulate in order to gain entry. Doing this requires much thought and precision in order to gain entry.
Hackers may be motivated by various motives – some criminal, and some benevolent. Cybercrime such as stealing personal or financial data for sale on the dark web often motivates hackers’ attacks, whether this involves quick “smash and grabs” or more in-depth penetrations into large networks where hackers remain infiltrating for months slowly gathering and collecting information.
Another driving factor was to establish street cred within the hacker subculture, leading to their designation as “hackers”. The name was coined for teenage vandals who broke into systems at organizations such as Los Alamos National Laboratory, Security Pacific Bank and Sloan-Kettering Cancer Center for the purpose of leaving their mark and solidifying their position within hacker culture.
Hackers also engage in corporate espionage, wherein they steal confidential or proprietary data from company systems to gain an unfair competitive edge in the market. This type of hacking often uses social engineering techniques like phishing scams or spam emails – these attacks can be especially devastating to companies and individuals alike.
