Microsoft have just revealed their new operating system - Windows 10. No, we don't know what happened to Windows 9 either! Nonetheless, the main aim of this new operating system will be to create a single interface that will work across many devices - desktop machines, tablets, mobiles, and even Xbox consoles. There will be a single app store that will service all of these machines.

Last week, a vulnerability (codenamed "Shellshock") was found in a tool called "Bash". This programme is installed by default on millions of machines, especially servers. Bash is a command line interface that is frequently used as the primary point of access to do carry out whatever tasks need performing on these machines.

According to emerging reports, there has been a major flaw found in the web browser that comes as standard in millions of Android devices. If exploited, this vulnerability would allow an attacker to view other websites that the browser may also currently be accessing.

We have seen an uptick of email from unknown sources with PDF attachments of late. It is worth restating that you should be very wary of ANY email from an unknown source regardless of the content. Attempts to compromise machines via email come in many forms. Most frequently, this will either be via a zip attachment, or a link to a malicious website. However, the people engineering these emails know that awareness of attacks in this form is increasing, so are always on the lookout for new ways to trick people into compromising their machines. This recent spate of emails fall into that category.

A "Zero-day" security vulnerability has been found in a Wordpress image resizing library called TimThumb. A "library" is a section of code that other bits of code can call on to perform a common task. Therefore, this means that lots of disparate plugins rely on this one "library" to perform image resizing. That in turn means that while it is only this one library that has the issue, many Wordpress plugins are now at risk because they all use this library.

So it’s about the time where I have a number of Exchange 2013 CU1 servers running on Windows Server 2013 that require upgrading to Exchange 2013 SP1. Remember take a backup before proceeding with major updates like this. I have documented the issues I hit on a couple of my installs here.
