Microsoft have published a Security Bulletin Summary for November 2011. A number of updates have been released including one "critical" and two "important" severity updates.

The patches address remote code execution, elevation of privilege and denial of service vulnerabilities. Importantly, an update has been released to patch the critical vulnerability in the TCP/IP stack (MS11-083). Microsoft report that "the vulnerability could allow remote code execution if an attacker sends a continuous flow of specially crafted UDP packets to a closed port on a target system."


Duqu, Son of Stuxnet

by Andy on October 20th, 2011 in Security Alert.

An apparently modified version of the well-publicised Stuxnet worm has been discovered on a number of corporate computer systems in Europe. Analysis suggests that the malware, named Duqu (pronounced dyü-kyü), appears to be based on the Stuxnet source code, giving rise to the possibility  that Duqu may have been developed either by the Stuxnet authors or by developers who have had access to the source code.


As the malware landscape evolves, it's helpful to understand how malware gets onto your machine. Knowing the bad guys' strategies gives you the edge while on-line and puts you in a stronger position to defend your data and PC against compromising threats.

We all know that we should install anti-malware software, keep it up to date and run regular scans, apply Windows and application security patches when they become available, use a firewall... well, I won't bore you - you know what to do. But what kind of attacks can we expect and where are they coming from?


Developing malware from scratch is a highly complex task that requires considerable skill and effort. In recent years, crimeware toolkits have taken the heavy lifting out of creating malware. Toolkits, such as MPack, Neospoit and Zeus, can be found for sale on underground hacking forums, lowering the skills barrier for would-be criminals. For a fee and with little effort, hackers can generate their own malware that can be used for stealing credit card details, passwords and other sensitive information.


Microsoft have published a Security Bulletin Summary for October 2011. Eight updates have been released including two "critical" and six "important" severity updates.

The patches address remote code execution, elevation of privilege and denial of service vulnerabilities within Windows, Internet Explorer, Microsoft .NET Framework, Microsoft Silverlight, Microsoft Forefront United Access Gateway and Microsoft Host Integration Server.

Adobe Reader X Released

by Andy on November 22nd, 2010 in Security Alert.

In response to the volume of malware exploiting Adobe products, Adobe Reader X was released last week with its much anticipated new security feature, Protected Mode.


Protected Mode is based on Microsoft’s "Practical Windows Sandboxing" technique which you can read about here.


What does Protected Mode do? It displays PDF files in a highly restricted and confined  environment. The restricted environment will help prevent a booby trapped PDF file from doing anything to your system.
