Hacker slang Glossary.

The Hacker slang Glossary was created for people to understand what words they see flying across the screen in IRC, or on this forum, actually mean! This can help you so you don't end up saying something stupid like "I think I broke my packet protocol please help me fix it!" or "Dude my client doesn't have any resources.".
The glossary is IN ALPHABETICAL ORDER! So if you want to find something quick you can just scroll, or CTRL+F for you lazy people. Also, post here if there is a term/word you want me to add, or correct me because I'm kinda tired so I could fuck up a little.

A-

B-
Brute Forcer:
A program which goes through a list of passwords and usernames until it finds the right one. (Password finder).
Blue Screen:
Microsofts error screen to descripe a critical problem with last memory actions listed that may caused the crash. Named after the blue background color.

C-
Client:
Usually a program that can download files for manipulation, request application-based services from a file server, or run applications.
Crash:
A serious computer failure. A computer crash means that the computer itself stops working or that a program aborts unexpectedly.
Cracker:
What is now used for hacking into one's station and destroying files, causing destruction.
Carding:
Hacking CCs for personal info, money, etc.
Cracking:
Software cracking is the modification of software to remove encoded copy prevention. Another type of cracking removes the trial period from shareware or trials making the product function as the full unlocked version. These cracks usually are programs that patch the program executable and sometimes the dlls.
Console:
Mostly the "close-core" part of a programm wich is command line based (e.g. Command Shells).
Compiler:
Used to convert a source code into a executable file (source to "machine code" convertation). Unlike interpreted programms compilied ones need to be recompilied on changes.
Cookie Stealer:
Another word for this is cookie grabber. What cookie grabbers do, is pretty much what their name is. This is usually done (if not, always) with a PHP script.

D-
Document:
[i]In the PC world, the term was originally used for a file created with a word processor. In addition to text, documents can contain graphics, charts, and other objects.
DOS(1) ( p, DDOS ):
Denial Of Service, or Distributed Denial Of Service is a verb word that is used to refer to take control of another computer, in a malicous way, sometimes to delete files, change system configurations, or even cause damage to your network.
DOS(2):
"Disc Operating System." An extremely old operating system.

E-

F-
Firewall (Hardware):
Network layer firewalls operate at a (relatively low) level of the TCP/IP protocol stack as IP-packet filters, not allowing packets to pass through the firewall unless they match the rules. The firewall administrator may define the rules; or default built-in rules may apply (as in some inflexible firewall systems).
Modern firewalls can filter traffic based on many packet attributes like source IP, source port, destination IP or port, destination service like WWW or FTP. They can filter based on protocols, TTL values, netblock of originator, domain name of the source, and many other attributes.
FTP:
File Transfer Protocol usually running on port 21

Firewall (Software):
Application-layer firewalls work on the application level of the TCP/IP stack (i.e., all browser traffic, or all telnet or ftp traffic), and may intercept all packets traveling to or from an application. They block other packets (usually dropping them without acknowledgement to the sender). In principle, application firewalls can prevent all unwanted outside traffic from reaching protected machines.
By inspecting all packets for improper content, firewalls can even prevent the spread of the likes of viruses. In practice, however, this becomes so complex and so difficult to attempt (given the variety of applications and the diversity of content each may allow in its packet traffic) that comprehensive firewall design does not generally attempt this approach.

G-
Graphic file extensions or terms:
AAF, ASF, BMP, CGM, CIE, color model, DIB, DirectDraw, DXF, EPS, FIF, FlashPix, GEM, GIF, IGES, IPIX, JPEG, OpenGL ,PCX, PGA, PhotoCD, PIC, PICT, PNG, QuickDraw, QuickTime, VR, RLE, SVG, TIFF, VRML, WBMP, and WMF.

H-

A hash value (or simply hash), also called a message digest, is a number generated from a string of text.
Hack(1):
To modify a program, often in an unauthorized manner, by changing the code itself.
Hack(2):
Code that is written to provide extra functionality to an existing program.
Hacker:
A slang term for a computer enthusiast, i.e., a person who enjoys learning programming languages and computer systems and can often be considered an expert on the subject(s).
Hacking:
Origionally meant to take a program a part and make it fast, over the years, the media have raped this work into meaning gaining access to someone's computer.
HTTPp:
Hyper Text Transfer Protocol (used for Websites) usually running on port 80

I-
IP-Spoofing:
Modifying a packets header to diguise your ip adress.
Intrusion Detection System(IDS):
It mostly detects attacks and itrusion attemps by comparing incoming packets with example patterns but there are also IDS's that use heuristic methods to detect unknown attack attemps. Also used to counter IP-Spoofing. Oftenly used in combination with a firewall.
Interpreter:
Used for interpreting source codes, unlike compiliers, Interpreters convert the source code "on the fly" to machine code (e.g. java, perl (partially), php, cgi).

J-

K-
Keylogger:
Small program which tries to stay invisble and records keystrokes. This is usually used for stealing passwords..

L-
Leecher / Leech:

SQL Injection:
It is a trick to inject SQL query/command as an input possibly via web pages. Many web pages take parameters from web user, and make SQL query to the database. Take for instance when a user login, web page that user name and password and make SQL query to the database to check if a user has valid name and password. With SQL Injection, it is possible for us to send crafted user name and/or password field that will change the SQL query and thus grant us something else.
