Increase in attacks on CVE-2010-1885
Microsoft is warning that there has been an increase of attacks against a zero-day vulnerability in Microsoft Help and Support Center.

It can be used to bypass restrictions normally imposed by a command-line argument to load arbitrary help documents. Proof-of-concept code has
Yes, Virginia, There is Cyberwar
DEAR EDITOR:
I have been in security for 8 years. Some of my friends say there is no such thing as cyberwar. My manager says, "If you see it on the VRT Blog then it's so" Please tell me the truth; is there cyberwar?

Virginia,
Your friends are wrong. They have been affected by the skepticism of a skeptical age. They do not believe except
IMPORTANT Rule Download Change
Today the Snort Web Team made a change to the way that Snort rules are downloaded from snort.org. Hopefully this will result in faster downloads for most people. The changes are highlighted below:We are changing the way we publish rules. In June 2010 we stopped offering rules in the "snortrules-snapshot-CURRENT" format. Instead, rules are released for specific versions of Snort. You will be
Smart Grids and the Importance of Smart Security Choices
I got a flyer in my mail a couple of days ago, telling me that my local utility company would be coming out soon to install a smart meter on my house.

That's when my curiosity got the better of me - even though I arrived home after dark, I had to go take a look at the shiny new toy on the side of my
ClamAV for Windows
Recently, we released the only official Windows-specific version of ClamAV, appropriately called ClamAV for Windows (http://www.clamav.net/lang/en/about/win32/). It is designed to use little memory and processing speed because it uses an advanced cloud-based protection mechanism, best of all it's free (as in free beer. Ummm...beeeeer).

Defenders of the Faith
Quite recently, Tavis Ormandy released a 0-day vulnerability in a prominent piece of software. For this transgression, both he and his employer received a good deal of bad press. Sadly, very few in the professional security researcher crowd made enough noise about this, and to the contrary, one man in particular came down squarely against him. Thankfully however we still have Brad Spengler.

So…you’re at the bar and across the room you see this incredible [insert whatever floats your boat here].You spend an inappropriate amount of your time watching this person and your mind starts to fill in the details that the dark environment masks. Then they turn around walk towards the bar and (finally!) walk into enough light that you can see what they look like. Your first thought…”KILL IT
Sourcefire VRT Expansion Plans (We are Hiring)
One of the hardest things in life is finding the right place to work, where you can spend eight to ten hours a day doing something you enjoy and also pay your bills. I’ve been lucky enough in my life to find this type of place three times: HiverWorld, Farm9, and Sourcefire. Each one of these places had a number of attributes that made it appealing to me, and made it where I wanted to spend the
