The CryptoPHP backdoor & what you need to know

Researchers at Fox-IT released a white paper regarding an increasing threat to content management systems they’ve named CryptoPHP.

What is the CryptoPHP Backdoor?

CryptoPHP is a threat that uses backdoored Joomla, WordPress and Drupal themes and plug-ins to compromise webservers on a large scale. By publishing pirated themes and plug-ins free for anyone to use instead of having to pay for them, the CryptoPHP actor is social engineering site administrators into installing the included backdoor on their server.

Operators of CryptoPHP currently abuse the backdoor for illegal search engine optimization, also known as Blackhat SEO. The backdoor is a well developed piece of code and dynamic in its use. The capabilities of the CryptoPHP backdoor include:

  • Integration into popular content management systems like WordPress, Drupal and Joomla
  • Public key encryption for communication between the compromised server and the command and control (C2) server
  • An extensive infrastructure in terms of C2 domains and IP’s
  • Backup mechanisms in place against C2 domain takedowns in the form of email communication
  • Manual control of the backdoor besides the C2 communication
  • Remote updating of the list of C2 servers
  • Ability to update itself

SSL 3.0 Poodle Vulnerability

SSL v3 Vulnerability

Google reported in a blog post today the discovery of a security vulnerability with SSL version 3.0. Our engineers were notified of this vulnerability before the announcement was made public and have made the necessary changes to disable access to SSL 3.0 on our core infrastructure.

Unlike the HeartBleed vulnerability, most of our users will not be impacted from this change. However, those that are using outdated web browsers (Internet Explorer 6 for example) will be unable to connect securely to our control panel and website.

If you’re using an outdated web browser, simply download the updated versions or download newer clients such as Mozilla Firefox or Google Chrome. These browsers utilize an enhanced security protocol known as TLS, which has the ability to automatically update keeping you secure in the future.

SSL Version 3.0 will be disabled on Firefox on November 25, but you do not have to wait for this to be released. You can download a plugin that will allow you to set the minimum SSL version. If you’re using Internet Explorer, simply go to Settings -> Internet Options -> Advanced Tab -> Uncheck SSLv3 under Security.

Our system engineers are working to disable SSL version 3.0 across all of our servers. This will be done in segments to ensure there is no impact your websites.

As always, you’re more than welcome to contact our support if you have any questions and/or concerns.

How to improve your SEO ranking on Google with SSL

Improve SEO Performance with HTTPS

Update: Google announced on December 18, 2015 that they have begun to index HTTPS URLs by default. This means that if both an HTTP and HTTPS (the secured version of the url) are both available, they will automatically choose to index only the HTTPS version. This is the case even if inbound links point mainly or only to the HTTP version of the url. According to Google this is the next step in their “HTTPS everywhere” initiative.

It’s not often that Google divulges any information about how it ranks websites on its search engine and usually leaves the process up to businesses and SEO experts to focus on creating quality websites. However, recently Google announced that the use of HTTPS on a website will be considered a ranking signal in their search algorithm. This will ultimately help the Internet become much safer and secure as webmasters work to take advantage of the search result benefits.
