Defending Against the New DOS Tool Slowloris

A new DOS (Denial of Service) application has popped up.

http://ha.ckers.org/slowloris/

It claims to be different because it uses a low amount of bandwidth compared to other DOS applications.

How it Works

Slowloris holds connections open by sending partial HTTP requests. It continues to send subsequent headers at regular intervals to keep the sockets from closing. (From the website)

By sending data as slow as possible, Slowloris aims to tie up all your sockets. When all of them are being used, no one else can connect. It should be noted that this it not a new principle. But it appears to be the first publicly distributed one.

The most popular web server Apache is supposedly extremely vulnerable due to the fact that it limits the total number of connections to an artificially low number.

Firefox 3.5 RC is Not Ready (for plugins)

Firefox 3.5 RC is not ready to use yet.

firefox

Notice how the scrollbar is on the left and the options are completely blank. I can’t even click on any links. You must right click and “Open Link in New Tab”.

I grabbed it from http://releases.mozilla.org/pub/mozilla.org/firefox/releases/3.5rc1/

Update

The bugs went away when I disabled extensions. Depending on what extensions you are using, it may also work for you.

Host Your Own Email: Easy Disposable Addresses

If you’ve been on the Internet for any extended period of time, you’ve probably felt annoyed at all the websites that require your email, and sometimes even put annoying checks on them.

Common Annoyances

  1. Requiring an email address and then sending a confirmation link.
  2. Websites that send their “free information” through email in a ploy to get your email address.
  3. Websites that reject all the free email providers. (You must provide a real email address, why is a free one not real??)

I hear half of you saying “you can use free disposable email websites”. This is true. A simple search on Google will bring up a long list of them.

However, I’ve increasingly found the websites to be offline, blocked by websites, or not receiving any email whatsoever.

So why not host your own email server? Well I looked around online, and found myself completely annoyed at the bulkiness and difficulty of setting up a simple catch-all, so I decided to make my own and share it with all of you.

Patching a Program Without Source Code: How to be like the Skype Hacker for Newbies

Recently I saw how this person was tired of how this 3rd party Skype plugin was crashing and decided to fix it without the source code.

I thought to myself, “its not really that hard or newsworthy, I’ve done it myself before.” Although it was for some obscure Korean MMO, it received a flurry of online response ranging from “I love you” to “I don’t trust this patch, and if I crash, everyone else should crash too”.

So here I will try to show you how to become a “leet hacker” that can patch unencrypted programs without the source code like the Skype guy, so commercial software companies can benefit from without paying you, and your screen name forever sung in ballads by traveling troubadours.
