LOIC

Fact ALERT: This is serious shit and has been known to cause drama and IRL Ban Hammers. Actually using this might get you v&. The information on page is provided for entertainment purposes only.

The Low Orbit Ion Cannon.

Probably the biggest LOIC hive you'll ever see.

LOIC (Low Orbit Ion Cannon) is an app, written in C# and developed by praetox that was exploited during PROJECT CHANOLOGY to attack teh $cifags's many web sites. It attempts to Denial of Service the target site by bandwidth raeping, sending TCP, UDP, or HTTP requests to the site until its ass looks like goatse. It is also in the Dangerous Kitten tools pack.

WARNING: this will cause srs nerd rage and make asspies have meltdowns, which will result in episodes of bawwing. Use at your own risk.

Instructions

LOIC in action.

To use:

• Get it from Google.
• Unzip
• Run (You need to logged in as admin)
• In the "IP address" box type in "127.0.0.1" (Yes, the TP3 self protocol)
• Click the obnoxiously huge IMMA CHARGIN MAH LAZOR button.
• ????
• Profit

This works by having many people spamming at the server at once. The more people who run LOIC the bigger the damage will be.
Protip: If LOIC gets stuck and doesn't send anymore requests in HTTP/TCP mode, restart flood. Also, higher number of threads means bigger kick but at the expense of your CPU/bandwidth.

Protip for Microshaft XP and Vista users

If you have Windows XP with SP 2 or higher or Vista you can't run LOIC right away as Microshaft's lameass restrictions won't let it really work. To break past the restrictions, you can do one of two things (moar info in Other Links section):

1. get Windows TCP/IP patch and run it first
2. Get Ubuntu Linux and Dual Boot like a badass motherfucker!

Protip: Use JS LOIC, see below, runs on all systems.

Windows 7 users

After you've applied the TCP-Z patch, run the original LOIC (WIN), packaged with Dangerous Kitten. If you use IRCLOIC you are moar than likely gonna surprise rape your Internet Hate Machine's capability to browse HTTP websites with your browser. Only other applications that require the internet will work, unless you reset your router or modem, which is a constant pain in the arse.

Epic Fail Cannon, Gay Pride Cannon and /War/rior's Battle Cannon

Trap. Only use either the original LOIC or IRC-LOIC. Delete EFC, GPC or WBC if you already have them, then run a scan. For more information check out this newpost: http://www.anonnewswire.org/entry/2009/07/31/efc-has-a-backdoor/

The programmer who made the "Epic Fail Cannon" thought it would funny to include a nice old trojan in the EFC code. While LOIC represents the glory and power of anonymous, in its collective power to dominate anyone found deserving their wrath, then being forced into it is just not cool because lulz is only lulz when everyone is part of it, not when its some sweaty basement dweller stealing your hard-earned bandwidth which is better spent on downloading porn

This is obviously a case of the EFC's maker being a gigantic cock-gobler who loves cock and would like some sent to his gaping, leaky and woe-fully unlubricated asshole. If he's any smart, he'll get some curtains an a dog

The result of your handiwork

Info pl0x

The original LOIC requires Windows and the .NET Framework to run it.

A New Java-based LOIC is also available on Sourceforge that will run all all systems including Lunix and Apple without needing faggy Microshaft's .NET framework!

This is a group-effort sort of program. One person running LOIC alone will not do much, but when multiple people run it at the same time the damage builds up fast. Help the cause: run LOIC today!

Strategies

	“	If you want to get an idea of how slow a website is, fire at it with HTTP mode. If some connect, then it's still not bad - noone's gonna get anything out of the website	„

	“	I think TCP is the best method, then HTTP comes second	„

Example of proper usage.

IRC-LOIC

Newfag and NewEraCracker updated LOIC for the Operation Payback to fix bugs and stuff.

This version has a hivemind feature which allows you to let someone else control the program to fire the lazor and choose targets via IRC.

This updated version works on Windows or later, and requires Microsoft .NET Framework 3.5 Service Pack 1. It also works on Linux with Mono or Wine with .NET Framework 2.0.

You can also start as hidden.

READ THE README.TXT WHICH IS INCLUDED, newfags.

Java LOIC

Works the same as normal LOIC, just doesn't require the .NET framework to run.

Open this file with 7-Zip for Java LOIC

Also contains a hivemind feature that is controlled via a Twatter account of your choosing.

JS LOIC

One most recent variant of LOIC is a new proof of concept that is floating around called JS LOIC. The “JS” in the title stands for JavaScript. JS LOIC is web based it can be run without needing to download or install anything. JS LOIC is more secure rather than requiring a user download program to run, someone can just visit a web page with a single HTML file and press a button to carry out their part of an attack.

Newfags FAQs

How do I use a proxy with LOIC?

• You don't. If you do you will simply be DDoSing the proxy instead. Think of it as trying to shoot a RPG at your neighbor's house behind your own fence. You will just end up destroying your own fence.

What if I get caught and V&d?

• DDoS'ing used to be safe. You used to be able to excuse yourself by saying "My computer was incorporated into a botnet, and then my computer was a zombie," but now the veil afforded by anonymity and working in groups is no more, and you can blame the overreaction to Operation Payback for it. As The Register puts it: "The LOIC does a poor job of preserving users' anonymity, hence the risk for anyone using it that they may come to the attention of local law enforcement agencies." Please take this time to pray for your imprisoned brothers-in-arms.
