Reading through the original Russian posting here http://www.securitylab.ru/news/240415.php&direction=re&template=General&cp1= It seems that someone has built an IOS worm that follows an EIGRP vector from router to router. I would say that means that enterprise networks are in more immediate danger than ISPs, however... This could be the first of many. The article does say that this is based on cross platform exploits but it isn't clear whether they mean "across different Cisco platforms" or whether there is some way for PCs to infect routers. The article has the tone of something written by a 3rd party therefore some of the facts may be a bit twisted. They do use this opportunity to point out that security through obscurity ain't all it's cracked up to be. Advice for reading Russian. When you get into difficulty, run the Russian through a machine translator using the PROMT engine like http://translation1.paralink.com and then GO BACK AND RE-READ the original Russian. Your brain will now be able to make a more accurate translation on the second pass. --Michael Dillon
