Curious Yellow, Superworm

jpmccord writes "Brandon Wiley's white paper, Curious Yellow, explains how "a superworm -- a worm that coordinates it actions among infected hosts and launches a massive distributed denial of service attack on any hosts it can't infect using those it can" (via disLEXia, a weblog by Maximillian Dornseif). The "doomsday scenario" frightens "even us", says Dornseif. An accompanying discussion rebukes Wiley's article a bit. Aaron Swartz's light-hearted take is rather entertaining: "So go read it now and find out how you can take over the whole Internet. And if you're going to, could you give me 24 hours notice?""

Doomsday scenario?

[Mika_Lindman]

The "doomsday scenario" frightens "even us", says Dornseif.

Doomsday? Hey guys, it's the internet! Who's gonna die if the internet shuts down? Come on now, it's not like the next ice age or nuclear war! 99% of worlds population won't give a shit if the internet shuts down for a few days. Who cares if a bunch of nerds freak out 'cause they can't read their emails?

The main question is, are YOU so addicted to the net, that you would use the term "doomsday", if it shuts down?

You apparently have no idea what the actual scope of the internet covers. Corporate and military communications, banking transactions, medical information tracking, etc, etc. Yes, we could live without the internet, but reverting to the "old fashioned" pen-and-paper snailmail transportation of information, even for short periods of time, could cost billions of dollars -- not to mention levels of annoyance it would cause in day-to-day life.

Actually in the UK each regional Trust communicates using direct lines between centres. If you send medical details between Trusts, it's still done via paperwork.

They trust the Internet about as much as I do ; )

Quite. There seem to be quite a few people out yelling about the "death of the Internet", much like people used to go around with sandwich boards with "The end of the world is nigh!" written on them. Perhaps they should take a few minutes and go read this rather excellent article at the Register and get a dose of reality. And after that, perhaps a re-reading of "Chicken Little" just to hammer the point home.

Mmkay... Call me stupid, but..

[Bowie J. Poag]

If you really think about it, the math behind such an event may not work out....My guess is, there simply aren't enough hosts on the net that are simultaneously A) succeptible to infection B) sitting on static IPs, and C) unmonitored by human eyes. All three conditions must exist in order for the worm to propogate -- If any one of those factors is absent, that particular thread of the superworm is halted. It makes the scenario described in this article practically impossible. Sure, a superworm may exist, but it would be so slow-moving and predictable that it would be no more a threat than any other form of DoS attack.

If you really want something abstract to think about, consider this: How is this "superworm" different than, say, a non-existant website mentioned on a nationwide TV broadcast? Instead of malicious code generating the resulting network congestion, its humans -- The net result is the same -- The effect will taper off as T increases. Nothing to really worry about, in other words.

Yeah, I know. I'm sure someones gonna come back and read this 10 years from now and want to slap me silly with a 10 lbs. trout, for my lack of forethought.. But seriously, I think these sort of stories are more along the lines of interesting fiction than they are real-world possibilities.

IMHO, there are plenty of susceptible computers out there.

Most internet servers, both large and small are on static IPs, and only subject to occasional human monitoring. (That is occasional, relative to this worm's speed of propagation, which is estimated to be under a minute).

I would include my home linux box in the category of susceptible computers. It is permanently connected (ADSL), on static IP, and I only use it every day or so. It it became infected with Curious Yellow, I would be unlikely to notice for 12 hours or so, (unless my ISP phoned me), and if the worm was stealthy enough not to monopolise any resource (CPU, disc, bandwidth etc), I might not notice for weeks until someone contacted me. Considering how infectious this hypothetical worm is, 12 hours would be enough to do huge damage.

Ask yourself if the same would apply to any permanently connected computers in your control?

As for "susceptible to infection". Curious Yellow would be designed to use some sort of zero day exploit, so we have no idea which computers are susceptible, and it would be complacent to assume that only windows boxes are. My system runs Debian Stable, and I regularly apply the security patches, but that does not make it completely invulnerable.

Don't be complacent, Treat the risk seriously.

tomorrow

[anshil]

Come on Pinky, let's prepare for tomorrow evening.

Why Brain? What are we going to do tomorrow evening?

Same as every evening, we try to take over the Internet!

we are just lucky...

[Lumpy]

These worm and virii writers are pretty harmless... If they were really malicious we would have seen Nimbda doing things like delete *.doc *.xls or format the hard drive.

A very scary worm would simply spread it's self quietly and slowly, wait for a doomsday time to tick and then Boom... simply start a massive delete fest on the computers or to be even more sinister start changing numbers randomly in spreadsheets and documents... like simply adjusting up or down by a random amount.

Once a virus or worm has admin control or system control it can do anything and luckily we still havent had one of these buggers do any destructive things...

I am expecting it though... It's just like guns... most of the planet can safely own and use them and only a few lunatics start blowing people's heads off.

New Slashdot Worm found in wild!

[MartyJG]

Anti-virus companies Norton and Sophos today announced they had spotted a new virus in the wild. According to anti-virus experts a new virus known only as "Curious Yellow" has been attacking the popular Slashdot.org site.

The site has already been hit twice, with a story appearing on their main 'articles' section. The virus has been spoofing known slashdot editors such as 'Hemos' and 'michael'. The site has yet to comment on these attacks, but have warned there is a risk that further variants may attack their 'slashback' section later this week.

So far there is no known cure for this virus.
