Microsoft Security Bulletin Summary for December 2012

Microsoft Security Bulletin Summary for December 2012 contains seven bulletins; five critical and two important. The key take away for this month's patch cycle is that most of the impact related to these vulnerabilities can be drastically minimized if the “least privilege” principle is enforced in organizations. It's always a good idea to look at the proliferation of administrative accounts, and many organizations can bring in the new year with fresh patches and limiting their administrative ac

White House Spear Phished

Yesterday news broke that an unclassified system at the White House Military Office was breached via a spear phish attack. The news of this attack is not surprising at all. Our government networks are under non-stop targeted attacks and some of these attacks will eventually compromise the intended victim. The reports that we've seen indicate that it was an unclassified network that was compromised. These types of systems are connected directly to the Internet, and wouldn't be considered mission

There's a Hole in the Network

In this post SecurityStreet meets Sesame Street. One of my favorite travel songs growing up was "There's a hole in the bucket". The song can literally go on forever, which can be headache inducing at times. Here's the Sesame Street rendition, it may hit close to home as it did with me. Why am I telling you this? Well, it feels to me like "There's a hole in the bucket" is a lot like "There's a vulnerability in the network". During my background in the military and government organizations, I

It's Time to Ban Bad Passwords

An important thing in the world of information security is to learn from our past mistakes. With 24-hour news cycles and the Internet, netizens seem to have developed very short memories.

Last week, LinkedIn password data was posted online with a total of 6.5 million SHA1 hashes. Being that only unique hashes were released the

Confusion over the FLAME platform and Flame Malware

I've seen a couple of postings on the Internet about a possible link between Flame malware with a project from National Laboratory for Scientific Computing (LNCC) in Brazil. They released a tool called Flexible and Lightweight Active Measurement Environment (FLAME) in 2009. This version of FLAME is a platform for prototyping network tools, which uses Lua as an extension language. FLAME allowed for the capability to deploy and remotely control packet flooding agents through instant messenger, and
