IRC Defender is a program designed for IRC networks, written in perl. It is highly a modular security service which amongst other things will keep virus and trojan drones from your network, allow you to set akills using regular expressions, and will prevent abuse of CGI:IRC proxies.

IRC Defender supports many IRC daemons including:

• bahamut
• dancer
• hybrid
• InspIRCd
• ircd 2.10
• unreal
• ultimate
• ptlink
• P10 (ircu, asuka)
• TR-ircd
• Dreamforge

IRC Defender is used on many small to medium sized networks.

We welcome third party development of modules, and will include any useful modules in the distribution.

After another long period of inactivity, 1.5 is now in a stable state. It can be downloaded from here.

Here's a summary of what's changed (top of the changelog)

File Modules/Link/inspircd11.pm
+ Small modification to FJOIN matching regex to take into account single and multiple nick forms

File Modules/Link/p10.pm
+ Added topic change detection (Thanks JonathanK@ChatSpike)

File Modules/Link/unreal.pm
+ Fix for the part regex so it passes proper values to handle_part

File Modules/Main.pm
+ added version_verbose config option

File Modules/Scan/cgiirc.pm
+ Change regex to detect older versions (thanks satmd@chatspike)

File Modules/Scan/spammage.pm
+ Fixed uninitialized value in chomp and problems with uppercase letters in channel names

File Modules/Scan/verbose.pm
+ added handle_kick
+ Fixed a problem that dumps lots of errors to the log file

File Modules/Scan/version.pm
+ added version_verbose config option
+ Changed so verbose setting doesn't print version responses during netjoin (it floods the control channel on large networks)

File defender.conf.example
+ Reformatted to 80 columns

To the skidiots that "hacked" us: (I say "hacked" because there's only a thousand different ways to take over an Invision forum this old that are fully documented with step-by-step instructions that even babies like you can read.) Thanks. I now know for sure that my backup scripts work 100%. You had perfect timing, as you picked the day after the first time in 2 months I ran my backup script to "hack" the forums. Again, thanks.

To everyone else: Normally I wouldn't have even given the clueless lusers the privilege of a response to their stupidity, but in the interest of full disclosure I am reporting that yes, there actually is a moron out there with nothing better to do with his/her time than take over a 5 year old Invision install that in all reality probably has no business being on the internet in the first place.

Everything is back to normal but I've chosen to shut down the old forums again.

(Second time I've had to fix this, it seems these lusers have no life. It's ok, I've got nothing better to do right now, and it only takes a minute to fix.)
