Direct from the Abuse Department
I have been asked to explain the inner-workings of how our DEFCON managed services interact with the functions of the Abuse Desk. In this message, I hope to impart upon you how certain situations are handled when the Abuse Desk becomes involved with the managed services provided by our Technical Support Staff.
Recently, we have become aware of a number of situations with Linux servers, where scripts have been uploaded via compromised PHP code and/or particular installed sub-modules, and allowed to execute in the /tmp and /dev/shm directories. These scripts cause harmful repercussions to both internal and external networks, including port scans, port flooding, brute force password attacks, or one of many other malicious scenarios (i.e. SPAMMING) that are against our authorized usage policy. These executable scripts are the product of vulnerable PHP scripts, which can be easily repaired. If you, or one of your customers is running a PHP forum, bulletin board, calendar, photo gallery, or any other code that is outdated or vulnerable, you may be open to such compromise.
The PHP installed modules, such as the forums, photo galleries, et al, can be uploaded by your customer via FTP or similar mediums, or through your control panel of choice, and subsequently installed to their public (HTTP) account space. These modules are considered end-user content and 3rd party scripting facilities, which we do not monitor. Keeping track of the content that the customer is uploading to the server is the duty of the server owner and administrator, and FastServers, as stated in our Official Policies, will not be held responsible for any vulnerable code your customers upload to your dedicated server. This applies to all levels of DEFCON service.
But we can offer sound advice! If you find a process running on the server, or executable file within /tmp or /dev/shm that looks like it could cause problems, please let us know by opening a new ticket, and we will help you to determine the next step in having your server audited and updated, or give you some additional direction in tracking down the issue yourself.
While being informative on this subject, I will now also let you know what happens when we see massive bursts of bandwidth on our internal bandwidth monitoring, and find these scripts being run from your server. The first time we find these scripts being executed from your server, we will send you an informative warning. If you are using SPAM blocking/filtering software, such as SpamAssassin, please whitelist the “fastservers.net” domain name. Responses to these emails are of extreme importance in making us aware that you are taking steps to rectify the problem. If you fail to respond to the email from us, and the issue happens again, we will disable your server via Ethernet, so it is absolutely critical that you keep your Pentagon profile updated with an email address that you check on a daily basis. Having the server re-enabled at this point will require you to discuss the situation with our Systems Administrators, as we must take a strong stance against a lack of response to our warnings and malaise in lieu of the critical nature of these AUP violations.
Communication on BOTH our parts is VITAL in keeping situations such as this from developing. Please note that the above information is geared to help, not hinder, but we must do everything in our power to maintain a secure network. This sometimes requires us to take steps, such as the ones described in the paragraph above, in order to keep an optimized, responsible networking model.
On another note, our AUP has had some changes made to it, as there have been technology advances in the file exchange protocols and the way that our policies have been shaped around this. Please check out our new and improved AUP here: http://www.fastservers.net/about-contact/company-policies.html.
As always, if you have any questions about our policies as described above, please let us know via abuse@fastservers.net, or if you have a technical question, we recommend logging into Pentagon and submitting a new ticket to our Technical Support Staff. Thanks for your time, it is much appreciated.
