February 6th, 2007, 10:17 PM #1Hackers causing major damage?
I was watching the news tonight and saw something were some hackers had taken control of one of the pentagons mega-computers so I looked it up and found this:
WASHINGTON - Hackers briefly overwhelmed at least three of the 13 computers that help manage global computer traffic Tuesday in one of the most significant attacks against the Internet since 2002.
Experts said the unusually powerful attacks lasted for hours but passed largely unnoticed by most computer users, a testament to the resiliency of the Internet. Behind the scenes, computer scientists worldwide raced to cope with enormous volumes of data that threatened to saturate some of the Internet's most vital pipelines.
Experts said the hackers appeared to disguise their origin, but vast amounts of rogue data in the attacks were traced to South Korea.
The attacks appeared to target UltraDNS, the company that operates servers managing traffic for Web sites ending in "org" and some other suffixes, experts said. Company officials did not immediately return telephone calls from The Associated Press.
Among the targeted "root" servers that manage global Internet traffic were ones operated by the Defense Department and the Internet's primary oversight body.

But on a slightly more serious note: while I deplore such acts, from a technical standpoint, you've got to be a little bit impressed. I do a lot of web development, and while I do not in any way condone such actions, it takes a lot of skill and know-how to put that much stress on the government's computers. The individuals responsible are gifted (I'll give them that). Incredibly misguided and needing to seek therapy, but gifted no doubt.

Actually, it was a few of the 13 root DNS servers, which are operated by various international bodies such as ICANN (Internet Corporation for Assigned Names and Numbers) and the Department of Defense. There are no governement secrets on here, and frankly they are not 'mega-computers' in any sense, actually quite a basic system with very little data.
Here's a brief overview of how it all works, if you're interested: http://www.isoc.org/briefings/019/
These are the servers responsible for top-level domains (TLDs) such as .com, .net, etc. We all have our sites such as whatever.com, which are technically 'sub-domains' of these TLDs. We control the DNS for our personal sub-domains, but these TLDs are operated by a few big international organizations.
Okay. Maybe that was all too boring.

Here's a graph of the root servers performance during the attack.
Looks like it was a minor league operation out of South Korea. The DOD servers/firewalls (G & H) responded well while ICANN's response (server L) could have been better.
IMO, this was a good fire drill for the root servers admins, with a real but weak and narrowly focused attack.

A good article with details & analysis of the attack.
1) Originated mainly from: Seoul 61%, Beijing 18%, San Francisco 13%.
2) Based on the strength and narrow focus of the attack, this likely was a precursor to another (larger) attack.
Most important is this statement:
"DDOS attacks are not only annoyances and service disruptions, but often are used as a distraction or cover for a "backdoor" attack, where an attacker can infect or steal data."
Looks like the experts are still worried about this, so it may be a good time to do a backup and print out a whois for each of your domains.

That means that it, and how it works, is interesting
