IRCu Family IRCd DoS Exploit

Wednesday, April 9th, 2008

Last month a new bug have been found in IRCu family IRCd’s which can be exploited leading to a crashing server.

In this post on Milw0rm the bug and exploit is explained. IRCu (<= 2.10.12.12) and many derivatives are affected.

IRC-Junkie asked Slug, who found the bug and described it on Milw0rm, how he found the bug. “Core dump from one of our servers,” Slug starts. “send_user_mode in s_user.c does not check that the argument after a +r mode is present, if it is not than the NULL sentinel may be missed, causing the function to iterate over the boundary of the array.”

Majority of Junk Traffic Consists of DDoS Targetted at IRC Servers

Tuesday, April 8th, 2008

Security Service Provider Arbor Networks studied the amount of junk traffic over the total sum of Internet traffic, and found some remarkable figures when it comes to IRC traffic.

Over the past 1,5 year the company analyzed data of 70 ISP’s. The findings show that on average 4% of all traffic is junk, such as spam and DDoS attacks topping 1,5TB of data, per second.

Of this 4%, on average 1300 DDoS attacks daily makes halve of the junk traffic. But on occasions, DDoS can make 5% of the total Internet traffic. Of the monitored DDoS attacks the majority consists of TCP SYN floods and ICMP floods targeted to IRC servers.

AustNet Moves to InspIRCd

Thursday, April 3rd, 2008

After being based on a modified IRCu for a long period of time, AustNet moves to an InspIRCd based IRCd. IRC-Junkie asks AustNet’s Praetorian about the how, why and what of this change.

“The previous IRCd that was in use, Austhex 7, had served AustNet for quite a long period,” Praetorian explains. “it was modified quite a bit, to accommodate things that were unique to AustNet, such as “helpers”, and virtual world, which when implemented, was quite unique for its time.”

Being so heavily modified it also offered serious challenges in the last days of its use. Sections of its code became so outdated modern compilers had problems compiling the code.

Yeah Right >:)

Wednesday, April 2nd, 2008

Obviously that was a lame attempt at an April Fool’s joke >:)

Naturally IRC-Junkie wasn’t the only one attempting:

InspIRCd announced The WOW Starts Now! The project would turn commercial with paid version ranging from Home Basic to Commercial. A free version named Basic would remain available. W00t explained: “It will continue to be available free for those of the world who cannot afford to pay for licencing. It includes an executable file built for redhat 5.1 on the 286 architecture with egcs 1.0 which may or may not work. YMMV.”

Site Changes

Wednesday, April 2nd, 2008

OK I know, this headline is one you’ve seen a few times before the past few months. In my rush to get phpBB out of the door I’ve probably took less time with the way things looked then I should have.

As you can see I changed back the graphics and color scheme of the old site (please shift-refresh if you don’t). I got quite a few messages of people preferring the old color scheme after the change, so I hope this fixes the way things look for a lot of people who expressed their discontent with the “neon look”.
