It is a bad worm, yes, and it's taking advantage of a problem that many linux users (but doubtfully the ones on PM have) and that's the lack of updating critical software. The worm's based off a bug found in January for the so-called Raman worm which had to be used in conjunction with wuftpd and one other client, and affect all versions of BIND except the most recent, 8.2.3 (non-beta). Nearly all major *nux vendors had patches out the same day, but quotes estimate that maybe only 50 to 75% of those running *nix took this necessary step.

This worm is using the exact same exploit, delievering a much deadlier protocol since it basically sticks a root kit on the affected box. And it's exploiting the fact that some *nix installs NEVER get patched for security holes (one article I read says that 20% of the internet is affected because of the number of *nix-based servers that have old BIND versions. But this is why I don't think most PM-ers will be affected, because we are computer professionals and know the value of security patches :D.

(Of course, the other trick besides patching is to stick the bind process behind a different user besides root, which means that a would-be attacker would not be able to root-kit your machine.)

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
