How to Learn the Basic Terms for Hacking/In today’s times, an online presence makes one vulnerable to unprecedented cyber attacks and a variety of malicious attacks on both small and large scales. On a daily basis, we encounter countless incidents of data breaches, information disclosure, financial theft and failing businesses. One doesn’t need to be technical minded to understand basic hacking terminologies which may one day render useful in case of a cyber attack.
How to Learn the Basic Terms for Hacking
Following is a list of important terms used in the field of hacking.
- Adware − is software designed to force pre-chosen ads to display on your system.
- Attack − An attack is an action that is done on a system to get its access and extract sensitive data.
- Back door − A back door, or trap door, is a hidden entrance to a computing device or software that bypasses security measures, such as logins and password protections.
- Bot − A bot is a program that automates an action so that it can be done repeatedly at a much higher rate for a more sustained period than a human operator could do it. For example, sending HTTP, FTP or Telnet at a higher rate or calling script to create objects at a higher rate.
- Botnet − A botnet, also known as zombie army, is a group of computers controlled without their owners’ knowledge. Botnets are used to send spam or make denial of service attacks.
- Brute force attack − A brute force attack is an automated and the simplest kind of method to gain access to a system or website. It tries a different combination of usernames and passwords, over and over again, until it gets in.
- Buffer Overflow − Buffer Overflow is a flaw that occurs when more data is written to a block of memory, or buffer than the buffer is allocated to hold.
- Clone phishing − Clone phishing is the modification of an existing, legitimate email with a false link to trick the recipient into providing personal information.
- Cracker − A cracker is one who modifies the software to access the features which are considered undesirable by the person cracking the software, especially copy protection features.
- Denial of service attack (DoS) − A denial of service (DoS) attack is a malicious attempt to make a server or a network resource unavailable to users, usually by temporarily interrupting or suspending the services of a host connected to the Internet.
- DDoS − Distributed denial of service attack.
- Exploit Kit − An exploit kit is software system designed to run on web servers, with the purpose of identifying software vulnerabilities in client machines communicating with it and exploiting discovered vulnerabilities to upload and execute malicious code on the client.
- Exploit − Exploit is a piece of software, a chunk of data, or a sequence of commands that takes advantage of a bug or vulnerability to compromise the security of a computer or network system.
- Firewall − A firewall is a filter designed to keep unwanted intruders outside a computer system or network while allowing safe communication between systems and users on the inside of the firewall.
- Keystroke logging − Keystroke logging is the process of tracking the keys which are pressed on a computer (and which touchscreen points are used). It is simply the map of a computer/human interface. It is used by gray and black hat hackers to record login IDs and passwords. Keyloggers are usually secreted onto a device using a Trojan delivered by a phishing email.
- Logic bomb − A virus secreted into a system that triggers a malicious action when certain conditions are met. The most common version is the time bomb.
- Malware − Malware is an umbrella term used to refer to a variety of forms of hostile or intrusive software, including computer viruses, worms, Trojan horses, ransomware, spyware, adware, scareware, and other malicious programs.
- Master Program − A master program is the program a black hat hacker uses to remotely transmit commands to infected zombie drones, normally to carry out Denial of Service attacks or spam attacks.
- Phishing − Phishing is an e-mail fraud method in which the perpetrator sends out legitimate-looking emails, in an attempt to gather personal and financial information from recipients.
- Phreaker − Phreakers are considered the original computer hackers and they are those who break into the telephone network illegally, typically to make free longdistance phone calls or to tap phone lines.
- Rootkit − Rootkit is a stealthy type of software, typically malicious, designed to hide the existence of certain processes or programs from normal methods of detection and enable continued privileged access to a computer.
- Shrink Wrap code − A Shrink Wrap code attack is an act of exploiting holes in unpatched or poorly configured software.
- Social engineering − Social engineering implies deceiving someone with the purpose of acquiring sensitive and personal information, like credit card details or user names and passwords.
- Spam − A Spam is simply an unsolicited email, also known as junk email, sent to a large number of recipients without their consent.
- Spoofing − Spoofing is a technique used to gain unauthorized access to computers, whereby the intruder sends messages to a computer with an IP address indicating that the message is coming from a trusted host.
- Spyware − Spyware is software that aims to gather information about a person or organization without their knowledge and that may send such information to another entity without the consumer’s consent, or that asserts control over a computer without the consumer’s knowledge.
- SQL Injection − SQL injection is an SQL code injection technique, used to attack data-driven applications, in which malicious SQL statements are inserted into an entry field for execution (e.g. to dump the database contents to the attacker).
- Threat − A threat is a possible danger that can exploit an existing bug or vulnerability to compromise the security of a computer or network system.
- Trojan − A Trojan, or Trojan Horse, is a malicious program disguised to look like a valid program, making it difficult to distinguish from programs that are supposed to be there designed with an intention to destroy files, alter information, steal passwords or other information.
- Virus − A virus is a malicious program or a piece of code which is capable of copying itself and typically has a detrimental effect, such as corrupting the system or destroying data.
- Vulnerability − A vulnerability is a weakness which allows a hacker to compromise the security of a computer or network system.
- Worms − A worm is a self-replicating virus that does not alter files but resides in active memory and duplicates itself.
- Cross-site Scripting − Cross-site scripting (XSS) is a type of computer security vulnerability typically found in web applications. XSS enables attackers to inject client-side script into web pages viewed by other users.
- Zombie Drone − A Zombie Drone is defined as a hi-jacked computer that is being used anonymously as a soldier or ‘drone’ for malicious activity, for example, distributing unwanted spam e-mails..
- NMAP – Nmap stands for Network Mapper. It is an open source tool that is used widely for network discovery and security auditing. Nmap was originally designed to scan large networks, but it can work equally well for single hosts. Network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime.
Nmap uses raw IP packets to determine −
- what hosts are available on the network,
- what services those hosts are offering,
- what operating systems they are running on,
- what type of firewalls are in use, and other such characteristics.
Nmap runs on all major computer operating systems such as Windows, Mac OS X, and Linux.
Metasploit is one of the most powerful exploit tools. It’s a product of Rapid7 and most of its resources can be found at: www.metasploit.com. It comes in two versions − commercial and free edition. Matasploit can be used with command prompt or with Web UI.
With Metasploit, you can perform the following operations −
- Conduct basic penetration tests on small networks

Angry IP Scanner
- Angry IP scanner is a lightweight, cross-platform IP address and port scanner. It can scan IP addresses in any range. It can be freely copied and used anywhere. In order to increase the scanning speed, it uses multithreaded approach, wherein a separate scanning thread is created for each scanned IP address.
- Angry IP Scanner simply pings each IP address to check if it’s alive, and then, it resolves its hostname, determines the MAC address, scans ports, etc. The amount of gathered data about each host can be saved to TXT, XML, CSV, or IP-Port list files. With help of plugins, Angry IP Scanner can gather any information about scanned IPs.
