HACKER DICTIONARY

Abbreviations

★ DDoS =
Distributed Denial of Service

★ DrDoS =
Distributed Reflected Denial of Service Attack, uses a list of reflection servers or other methods such as DNS to spoof an attack to look like it's coming from multiple ips. Amplification of power in the attack COULD occur.

★ FTP =
File Transfer Protocol. Used for transferring files over an FTP server.

★ FUD =

★ Hex =
In computer science, hexadecimal refers to base-16 numbers. These are numbers that use digits in the range: 0123456789ABCDEF. In the C programming language (as well as Java, JavaScript, C++, and other places), hexadecimal numbers are prefixed by a 0x. In this manner, one can tell that the number 0x80 is equivalent to 128 decimal, not 80 decimal.

★ SE =
Social Engineering

★ Skid =
Script Kid/Script Kiddie

★ SMTP =

Dictionary Attack =
A dictionary attack is an attack in which a cyber criminal can attempt to gain your account password. The attack uses a dictionary file, a simple list of possible passwords, and a program which fills them in.

Encryption =
In cryptography, encryption applies mathematical operations to data in order to render it incomprehensible. The only way to read the data is apply the reverse mathematical operations. In technical speak, encryption is applies mathematical algorithms with a key that converts plaintext to ciphertext. Only someone in possession of the key can decrypt the message.

Exploit =
A way of breaking into a system. An exploit takes advantage of a weakness in a system in order to hack it.

FUD =
Fully undetectable, can be used in many terms. Generally in combination with crypters, or when trying to infect someone.

Grey Hat =
A grey hat hacker is a combination of a Black Hat and a White Hat Hacker. A Grey Hat Hacker may surf the internet and hack into a computer system for the sole purpose of notifying the administrator that their system has been hacked, for example. Then they may offer to repair their system for a small fee.
Hacker (definition is widely disputed among people...) = A hacker is someone who is able to manipulate the inner workings of computers, information, and technology to work in his/her favor.

Hacktivist =
A hacktivist is a hacker who utilizes technology to announce a social, ideological, religious, or political message. In general, most hacktivism involves website defacement or denial-of-service attacks.

IP Address =
On the Internet, your IP address is the unique number that others use to send you traffic.

IP Grabber =

The art and science of cracking the phone network.

Proxy =
A proxy is something that acts as a server, but when given requests from clients, acts itself as a client to the real servers.

Rainbow Table =
A rainbow table is a table of possible passwords and their hashes. It is way faster to crack a password using rainbow tables then using a dictionary attack (Bruteforce).

Remote Administration Tool =
A tool which is used to remotely control (an)other machine(s). These can be used for monitoring user actions, but often misused by cyber criminals as malware, to get their hands on valuable information, such as log in credentials.

Resolver =

Reverse Engineering =
A technique whereby the hacker attempts to discover secrets about a program. Often used by crackers, and in direct modifications to a process/application.

Root =

Social Engineer =
Social engineering is a form of hacking that targets people's minds rather than their computers. A typical example is sending out snail mail marketing materials with the words "You may already have won" emblazoned across the outside of the letter. As you can see, social engineering is not unique to hackers; it's main practitioners are the marketing departments of corporations.

Trojan =
A Trojan is a type of malware that masquerades as a legitimate file or helpful program with the ultimate purpose of granting a hacker unauthorized access to a computer.

VPS =
The term is used for emphasizing that the virtual machine, although running in software on the same physical computer as other customers' virtual machines, is in many respects functionally
equivalent to a separate physical computer, is dedicated to the individual customer's needs, has the privacy of a separate physical computer, and can be configured to run server software.

Warez =
Software piracy.

White Hat =
A "white hat" refers to an ethical hacker, or a computer security expert, who specializes in penetration testing and in other testing methods to ensure the security of a businesses information systems. (Good guy, per se)

Worm =
Software designed to spread malware with little to no human interaction.

Zero Day Exploit =
An attack that exploits a previously unknown vulnerability in a computer application, meaning that the attack occurs on "day zero" of awareness of the vulnerability. This means that the developers have had zero days to address and patch the vulnerability.
