How do you dispose of three Petabytes of disk?

May 12, 2016
July of last year we had a little problem.  We had a lot of drives to dispose of and did so as inexpensively as possible via a drill press, a lot of time, and a lot of flying metal as we slowly destroyed stacks of drives one at a time.  Moving forward in time to today, we realized that our bins were once again full of drives, almost 1500 this time.  This adds up to almost three petabytes of storage in disks.  Knowing that it would take us days of drilling we sought out a faster solution, and here it is.

How do you dispose of a Petabyte of disks?

July 9, 2015
With the advent of massive inexpensive storage also comes the issue of the disposal of that storage when it inevitably fails on you, usually taking something valuable with each failure. Even the best of disks will fail eventually and at the end of the week you have a large steaming pile of disks that are no longer useful but cannot just be tossed into the rubbish bin.

Of Scannings and Statistics

August 22, 2014
We have been engaged in scanning of the internet for its better health for over a year (we started with a few, then grew to a dozen).  The decreases in abusable systems has dropped significantly in several areas.  We have also had an inadvertent effect of identifying networking misconfiguration on many networks which has helped improve the stability and security of those organizations.

Houston, we have a problem

Reporting has been fixed and all data going out in the reports again.

The scannings will continue until the Internet improves

March 28, 2014
The news and our networks have been full of articles and packets related to the different UDP amplification attacks that have been ongoing.  We and several other researchers have been looking at this problem for a while and while there are not any easy solutions we can at least make network owners more aware of the issues that we can see on their networks from the outside. This has led to some interesting results, most of which are not pleasant.

Surprise! You have ntp!

Shadowserver added a new set of reports to all of those who have signed up to receive information about their networks.  The report is the culmination of months of work figuring out how to reliably scan the Internet for potential Distributed Denial of Service (DDoS) amplification.

Displaying Shadowserver Data with Maltego

July 24, 2013
One of our core missions is to provide actionable data to network owners and researchers. Given this mission, we are constantly on the lookout for new and interesting ways to deliver our data and we are now pleased to announce that we have published a Maltego transform compatible with the Malformity Project.

How do you lose 30 million malicious samples?

April 7, 2013
As individuals and as a group we have been collecting malware for many years. The Shadowserver Foundation repository dates back to 2005 and we collected our first million shortly after we actually started counting.

Beware the trolls, secure your trackers

August 14, 2012
You track botnets? Right, we do as well. You spent your weekends building your slick botnet trackers and some fancy web interface? Damn, we did too. But let's face the truth, DDoS is boring. What gives better sense to your day than some random crook trolling you and your monitoring infrastructure? Nothing. So here's what happened today...

Of House Cleaning and Botnet C&C's

March 7, 2012
In the last couple of weeks we have dropped almost 2500 C&C's from our tracking system. This may seem extreme but is was something of a necessity. It should also bring up the question of validity of the rest of our C&C counts that you see.
