Hey, Same guy that "released" the norton start/stopkeylogger .. http://www.hm2k.org/news/1141413208.html the comments provide some more info On 4 Mar 2006 05:42:11 -0000, ryanmeyer14 () netscape net <ryanmeyer14 () netscape net> wrote:
It appears that various routers are prone to an IRC-only DoS attack. Particularly Netgear and Linksys routers have been shown vulnerable. If a client behind one of the vulnerable routers connects to an IRC server on port 6667 (and only 6667, does not DoS with other ports) and a user posts the following string in either a channel, private message, ctcp, notice, etc.. the router will drop the connection. The string is as follows: DCC SEND anylongrandomstringhere It is most commonly being seen as DCC SEND "string" 0 0 0 but that appears to be unneccessary. The string does need to be 15+ chars in length. Further, it appears the routers that are vulnerable to this are running vxworks as their embedded OS. Older linux Linksys routers appear to be immune.
