What the Heck Is FeeLCoMz?

FeeLCoMz is a string I often get a lot of questions about. Basically, people see it and other strings in their logs, or if they are unlucky, they run into it like this, in a file in their web directories:
 Basically, if this is in the file system, then the system has been compromised, usually by a PHP RFI vulnerability. Other strings to check for, if you feel you want to run some basic grep checks against web files, include: 
“ProGraMMeR”,”CyBeRz” and “mIRC”
If you find those strings, they usually indicate other PHP scanners, worms or attack tools have compromised the system. Now, if you don’t find those, it does NOT mean the system is safe, the list of all of those relevant strings would be too large and dynamic to manage. 
Another good grep check to parse files for in web directories, especially PHP and text files, if the nearly ubiquitous, “base64_decode(“, which is an absolute favorite of PHP bot, shell and malware authors. Any files you find using that call should be carefully inspected.

Basically, if you find files with the FeeLCoMz tag in it in the web directories, you have some incident response and investigation work to do. Let us know if we can assist, and stay safe out there. 
PS – It’s a good idea to have all PHP applications, even common ones like WordPress and the like, assessed prior to deployment. It might just save you some time, hassle and money! 

Excellent Source for Metrics on PHP RFI

My friend Eric has put up some excellent statistics and metrics on PHP RFI attacks against his honeynet. This is some excellent data. If you have read other stuff we have pointed to from Eric, then you know what to expect. But, if you are interested in a real world look at trends and metrics around PHP exposures, give this a few moments of your time.

You can find the interface and metrics set here.

Check it out, I think you’ll be impressed. Thanks, as always, to Eric and other folks in the honeypot community for all of their hard work, time and attention.

If you have some honeypot metrics to share, drop a comment below! As always, thanks for reading!

CA ARCserve DoS, Multiple CMS Vulns

Computer Associates ARCserve Backup 12.0.5454.0 and earlier can be Denial of Serviced by sending a specially crafted packet to port 41523. For more specific information please see CVE-2008-1979.

Several Content Management Systems are vulnerable to Remote File Inclusion (RFI) and SQL injection. As Adam said in a previous post, it appears that application developers are still not embracing the proper coding procedures that allow for these exploits to be developed. If you are an admin of a CMS please make sure that your application is tested regulary for any injection vulnerabilities.
