Code Red Worm Spreading, Set To Flood Whitehouse

altek writes: "CNET has an article describing a worm that has taken down over 12,000 MS IIS webservers." Bill Kendrick points to another CNET story, which reports that the worm will "cause every infected computer to flood the Whitehouse.gov address with data starting at 5 p.m. PDT," writing "Time to shut down all those IIS servers before the Internet gets flooded."

Slow Internet service due to all those extra packets of malice may not be the worst effect: As sp1n writes: "It appears that due to the way the worm formats its HTTP request and the semi-random way it seeks out vulnerable systems, it is also causing Cisco 67x DSL routers, widely deployed by Qwest, using firmware prior to 2.4.1, as well as some others, such as 3Com LanModems, to crash -- recoverable only by a power cycle. I have yet to see any news outlet cover the affect this is having on DSL service. Qwest's Interprise networking department confirmed they are receiving reports from all 14 states in their territory. Some routers running pre-2.4.1 firmware are crashing even though the web admin is disabled. This has become a huge support nightmare for every ISP in the region."

    I, and many of my co-workers, had our home DSL routers (Cisco 675s) lock up today as this worm scanned them.

    There is common belief that disabling the web interface will prevent this. It's not true; mine's been disabled every since this was first reported a year ago and I still got hit. The problem is that "set web disable" prevents the web server from fiddling the router config, but doesn't actually stop the server from parsing input from port 80, which is what locks up the box.

    An improved workaround is to disable the web-admin interface and change its port number with "set web port 53496" (replace with some random port number). At least that'll stop it for the near term.

    Long term you need to get updated firmware, but of course Cisco won't distribute firmware directly to customers, even though they have public announcements of the existence of bugs and bugfixes. To actually get the firmware you have to get it from your DSL line provider (Qwest, in my case), and Qwest couldn't care less about security with respect to home users, so they've never bothered to offer fixed versions of CBOS.

    Here is the snippet from bugtraq:

    Thanks to Eric from Symantec for tossing us a note about the worm being Date
    based and not Time based.

    We made an error in our last analysis and said the worm would start
    attacking whitehouse.gov based on a certain time. In reality its based on a
    date (the 20th UTC) which is tomorrow.

    If the worm infects your system between the 1st and the 19th it will attempt
    to deface the infected servers web page or try to propogate itself to other
    systems. On the 20th all infected threads will attempt to attack
    www.whitehouse.gov. This seems to continue until the worm is removed from
    the infected system.

    Any new infection that happens between the 20th and 28th will most likely be
    someone "hand infecting" your system as all other worms should be attacking
    whitehouse.gov. If for some reason you are infected between the 20th and the
    28th then the worm will begin attacking whitehouse.gov without trying to
    infect other systems. This attack will continue indefinitly.

    The following are rough numbers, but we felt that it was important to
    illustrate the affects this worm can _possibly_ have.

    The worm has a timeline like this:

    day of the month:
    1-19: infect other hosts using the worm
    20-27: attack whitehouse.gov forever
    28-end of month: eternal sleep

    Presumably, this could restart at any point in a new month again.

    Also, some stats for the attack:

    Each infection has 100 threads
    Each thread is going to send about 100k, a byte at a time, which means you
    have a (40 for ip + 1 for each byte) which means you have 4.1 megs of data
    per thread
    100 threads * 4.1megs = 410 Megabytes
    This will be repeated again every 4.5 hours or so

    Remember, each host can be infected multiple times, meaning that a single
    host can send 410MB * # of infections.

    We have had reports between 15 thousand and 196 thousand unique hosts
    infected with the "Code Red" worm. However, there has been cross infection
    and we have heard reports of at least 300+ thousand infections/instances
    (machines with multiple infections etc..) of this worm.

    If there are 300 thousand infections then that means you have (300,000 * 410
    megabytes) that is going to be attempted to be flooded against
    whitehouse.gov every 4 and a half hours. If this is true and the worm "works
    as advertised" then the fact that whitehouse.gov goes offline is only the
    begining of what _can_ possibly happen...
