BlueSecurity Fall-Out Reveals Larger Problem 366
mdrebelx writes "For anyone following the BlueSecurity story, sadly the anti-spam crusader has raised the white flag. Brian Krebs with the Washington Post is reporting that after BlueSecurity's announcement, Prolexic and UltraDNS, which were both linked with BlueSecurity through business relations came under a DNS amplification attack that brought down thousands of sites.
While much of the focus about the BlueSecurity story has been centered on the question of what can be done about spam, I think a bigger question has been raised - is the Internet really that fragile? What has been going on is essentially cyber-terrorism and from what has been reported so far the terrorist clearly have the upper hand."
interesting question about fragile (Score:5, Insightful)
There have been other outages, major, which have had significant impact. It's a good question: is the internet that fragile?
In many ways it probably is. At the same time, the infrastructure seems resilient enough. The world so far hasn't laced up life-and-death critical systems to the internet such that a failure could cause loss of life. Well, that is, if you don't include:
Oh, wait, I guess people have started doing that.
What mechanisms exist for more than resiliency, i.e., instant self-healing? Could terrorists with a little knowledge and a few well-placed EMP generators disable major segments of the internet?
Unlike phones and the phone networks which were built with lots of oversight and regulation (Universal Service was a big driver for this (aside: now that everything is profit driven, don't expect phone service at that farm house at the end of that long country road anymore... noone HAS to provide it)), I'm not aware of what safeguards back up the internet. In my entire lifetime, I've not one time experienced a phone outage, not once! Power outages, etc., the phone companies have backups to backups to ensure service (though there is the occasional and hard to manage for ditch digging incident).
While large pieces of the internet are built upon the phone companies' infrastructure, other pieces aren't, and there are significant additional layers of complexity not in the phone companies' purview (switches, routers, coax cable from cable companies).
That question, "is the internet that fragile?", is probably the biggest reason I've never opted to switch my phone service to VOIP yet. I'd hate to be the one (tiny chance, I know) who needs to make that one 911 call and not be able to do so because the internet is unavailable (which happens occasionally here, which is also too often).

Yeah, there will be few bystanders who may get nabbed but most of these bystanders will be the geeks who are pushing their broadband connections to the limit and they will contact the ISP and get their connections re-instated. The clueless users, whoch have been own3d by the hacker will have to find someone to clean up their pc's caoghing up some dough which will make them a little more carefull about listening to people when they were told not to open attachments to see the cute dog pictures or accept free product offers from inscrupulous websites.
If you do not hold the ignorant users' feet to the fire, this zombie issue will not come to an end. Yes, we al know that, Redmond's finest operating system is no more than a joke when it comes to security, but if one is buying this crap, they should be ready to keep it safe and secure or find some other platform, let it be mac or linux or what have you.
I for one, am sick and tired of seeing the spammers to go unnoticed while the solution, regardless how brutal it is to the end user, goes unnoticed. Enough is enough !
