Dutch anti-piracy foundation website DoS attacked

Wednesday, June 24th, 2009

Yesterday, the Dutch anti-piracy foundation BREIN has summoned The Pirate Bay founders to appear in court for their part in the file-sharing activities of the users of The Pirate Bay.
Today, hackers have performed a Denial Of Service (DOS) attack on the website of BREIN ( www.anti-piracy.nl) which brought the complete website down.
According to a spokeswoman of BREIN they plan to have the website up and running as soon as possible. She also added to say, that such an attack is highly exceptional.

Well, I have seen this coming. The Pirate Bay is one of the biggest torrent sites around, and summoning them for court probably has pissed a lot of people off…

A new way to be spammed

Wednesday, June 17th, 2009

Opera just released their new “Unite” browser, which is according to them revolutionary. It is not only able to browse the Internet ( as a browser is supposed to do ) but it can also serve files and web pages and stream music to others, and it lets users leave post-its on a virtual fridge. According to their website, the latter function is “open to all” which basically means everyone can leave these messages…

Let’s see how long it takes before spammers are leaving you spam post-its on your fridge…

Twitter used for recruiting Hacktivists

Tuesday, June 16th, 2009

Some interesting developments on Twitter. Due to the disorder caused by the recent Iranian elections someone has decided to widen the scope of the disorder to the internet. He has asked people on twitter to help him DDoS Iranian government websites. As he stated in his Tweet, he ( and probably some others) successfully took down one website already.

But other Tweets show people don’t want this to happen. Because Iran’s Internet infrastructure is not as state-of-the-art like most western countries it could be possible the  internet of Iran saturates and they have no internet at all!

It’s kind of disturbing to see how easy it is to get people motivated on twitter, for the cause of good or the bad.

Strange e-mail originating from exchange server

Monday, June 8th, 2009

Today a friend asked me to look at something strange he found in his logs.
To better understand the situation, I’ll describe his network setup:

He runs a linux server with postfix, spamassassin and clamav antivirus which removes all spam and virusses received from the internet. All legitimate e-mail is then routed to his exchange server. E-mail that is sent by users on his network is relayed back to the linux server and then sent to the destination.

Last week he was checking his mail logs on his linux machine and he noticed his box was receiving e-mail from strange e-mail addresses. He figured: Well, no surprise there: Probably spam messages. Until he looked at the ip address from which it originated: It was the ip address of his own exchange server. First thing he did was doing a full virusscan of his exchange server. Nothing. He tried some spyware scanners, but again: Nothing. So he called me.

Why is bad WIFI encryption still being used?

Thursday, June 4th, 2009

Yesterday I was goofing around with kismet, a wireless network sniffer, and found sixteen acccesspoints within my range. I wondered which had bad encryption, so I sorted them on WEP key encryption. It turned out two where un-encrypted and eight where encrypted with WEP! I still do not get it. Why is WEP still being used by so many people? I can relate to the fact that people don’t encrypt at all: Some manufacturers just enable wireless out of the box and people just connect the device and notice it’s working. So they will not bother configuring the device if it is already working. But the ones with WEP had to have configured their device, so why not configure it to WPA?

Or perhaps I should reconsider my question? Why do manufactures not pro-actively promote the use of WPA in the web-gui for non-experienced users? The WPA2 standard has been optional in devices since 2004, and required since 2006. And WPA ( non -2 ) has been out for even longer. So why not enable WPA by default, or atleast point out WPA is more secure?

Any insights?
