Can I have cxs run a custom script before reporting or acting on a possible threat, so that the script itself can rule out false-positives or take action?

I've been getting a lot of useful hits on social.png files being uploaded via ftp. These are potentially dangerous, as they could be from the CryptoPHP malware. However, a simple check using the file command can tell me whether it's PHP script...

Hello, CryptoPHP is a threat that uses backdoored Joomla, WordPress and Drupal themes and plug-ins to compromise webservers on a large scale.

I have several servers blacklisted because of one or two costumers having their websites hacked.

Does cps have or will have in a short short period any kind of tool for detecting and preventing this infection?

Hi peeps,

I'll start asking a bit of patience from you. I'm a newbie to CXS and
rather a freshman when it comes to servers...

After being stung by hackers, we had our hosting provider install CXS on our server.

I've configured as much as I could however I keep on getting this email

Hi every day I get this alert:
cxswatch Scanning /home/vinaio/public_html/media/dojo/20140917:
# World writeable directory:
'/home/vinaio/public_html/media/dojo/20140917'

As dojo is a legitimate folder, I added it to the /etc/cxs/cxs.ignore list (dir:/home/vinaio/public_html/media/dojo/20140912) and then added this option to cxswatch:-I /etc/cxs/cxs.ignore
But I still get the same daily alert....

Hi,

We run CXS over all our fleet each week for a full scan, and one server sends dozens of messages towards the end of the scan which are all pretty much the same, only with the addition of an account of two extra having been scanned.

I did notice that this server runs the cxs update via a cron every morning which would make this occur right in the middle of the weekly full scan - could this...

Hello.

My modsecurity rule:

Hi,

I get the following exploit on a site:
# Known exploit = [PHP Exploit ]

How do I find out more about the exploit? I know that WordPress sites are affected by it and it's the first line of the file, but the various files look different.
What's the signature?
How can I grep for this particular exploit's footprint?
P0358 references the local bayes db I think, or is it a reference to an...

Hello,

How can i block file with this script:

Thank you

With every account that runs a wordpress blog on our server, I've been getting this, starting around July 2nd.

I thought it might be the wysija plugin that was recently reported to have a security bug, but all of the sites don't have the plugin this refers to.
Still, the IPs these come from are all from suspect countries, so it's not an accident.
Each cxs entry has a different IP listed as the...

I know all about the cxs.xtra file which adds signatures (sort of) to be detected by my installation of CXS, is there a place though to submit files to be added/analysed by ConfigServer to CXS.

I manage a bunch of servers and I come regularly accross files that are not detected by CXS and would love nothing more than to submit them so they are added to the scan engine.

Hello,

In an old installation of cxs, the cxs daemon cannot longer start cxs (Watch Daemon - cxs Watch is not running), and the message I get is
ERROR: Attempt to restart unknown service cxswatch

I have uninstalled and re-installed cxs but problem still exists. Any ideas what might cause this issue please?

Thanks

Hi Everyone,
I am currently having issues with spammers gaining access to some of my websites. They are uploading spam scripts but cxs is not detecting them? How can I configure CXS to pick up these new spam scripts as it is causing major issues with regards to my servers getting blacklisted for spam!

Thanks

We have cxs and configserver running on a server and received the following from abuseeat.org. I am running the latest versions. Any recommend way to track down this script? I have grepped all files in /var/log/ but have found no occurrence of the IP 87.255.51.229 listed. The system runs Apache in ruid2 so php processes are ran at the user level. Is there anything in the latest cxs to cover...
