In November of Microsoft standardized its patch release cycle. By releasing its patches on the second Tuesday of every month Microsoft hoped to address issues that were the result of patches being release in a non uniform fashion.
This effort has become known as Patch-Tuesday. The 10th out-of-band patch released by Microsoft is outlined in the MS security bulletin. The naming convention is read as such:. Using a ruby script I wrote I was able to download all of Microsoft's security bulletins and analyze them for information.
What I learned was in , Microsoft released 78 Security Bulletins dealing with security patches. However all these patches were still released on patch Tuesday with the exception of two. MS was the later of the two patches released and it was rated Critical for all supported editions of Microsoft Windows , Windows XP, Windows Server , and rated Important for all supported editions of Windows Vista and Windows Server At the time of release the Conficker worm was taking advantage of MS in the wild and exploiting every vulnerable system it came across.
This no doubt played a major role for this patch being released out of band. Fun Fact: Stuxnet which some have said is the most sophisticated malware to date also took advantage of MS I still very frequently find organizations vulnerable to MS Usually these systems are one offs that have managed to slip through the cracks of patch management some how. Other times I find people doing silly things such as scanning their network for Conficker worm with the idea this is some how protecting them.
This is not to say searching for exploited systems is a bad thing, however if the thought is somehow this is protecting the organization from an attack, this is simply wrong. Find out in 15 seconds.

There were even calls for us to release a patch for Windows ME and 98, which were affected but long out of support. I heard we even had to re-spin DVDs so that Steve Ballmer wasn't handing out vulnerable copies of Win7 beta at the Build conference, but I never could confirm that one.
Ziv: It all started when the Trustworthy Computing folks, headed by John Lambert, approached us with the alarming information about a new severe zero-day in Windows. That team had developed a method for identifying unknown zero-days from crash reports.
Using that method, they tracked the number of crashes from unstable attempts for exploiting the MS vulnerability. Once notified, the MMPC malware analysts developed an internal antivirus signature to help us find exploits of this dangerous bug. At that point, despite the huge malware repository the team maintained, very few non-replicating malware samples exploiting this bug were discovered. Later, in coordination with the release of the famous MS security update, we released the public signature to help protect customers and collect telemetry that would indicate the spread and geo-distribution of attacks.
We knew more malware would soon follow now that the information was in the public domain. The bad guys couldn't miss an opportunity such as this to exploit computers en masse during that brief time when the patch was not yet broadly installed. I published a blog on the MMPC blog urging people to install the patch with no delay. The title of that blog conveyed that message: " Get Protected, Now!
As expected, this out-of-band release immediately captured the attention of the media, including Brian Krebs who was still writing for the Washington Post:. In the coming days, we held our collective breath, checking telemetry closely — almost hour-by-hour. More crashes were being reported, so it was obvious that people out there were experimenting liberally with those exploits.
In early November, about a month after the initial discovery of the vulnerability, new malware emerged, exploiting it, however its prevalence was still very low. A few weeks later, the Conficker worm broke out but we'll keep that story to the second blog in this series. Phillip: This was the first of several incidents where we were able to see attacks in early stages before they became widespread. I remember the excitement that we might have a chance to stop a much-broader attack.
It was that opportunity that focused our conversations and drove the teams hard to develop a solution for this vulnerability. Seventeen days from knowledge to release with teams around the world working to secure customers was an amazing pace and experience to be part of. The second big memory of this incident was the spike in activity which led to the out-of-band release decision.
As we worked diligently on the fix detections of this attack were one or two a day — clearly not a widespread attack. Then on October 15 th we saw telemetry shoot up to twelve attacks.
Admittedly twelve is not a big number, but it was a big jump in activity and we only saw the cases where it failed. For me at the time, that was a big jump in risk. The difference between the attacks we knew about and an internet-wide worm like Slammer or Blaster was just the good intentions of the attacker.
That would be a phrase that I repeated as we debated our release plans and pressed the fixes. Ultimately we decided that the balance of risk favored a quicker release.
It was only after the update release when we were able to retrieve logs from the attackers' infrastructure that we saw the spike we observed was a significant ramp and preparation for larger scale attacks that combined graph is in the refresher deck we linked to above. The third big moment from this incident was the announcement of the release. The relatively new Advanced Notification Summary practice was executed 24 hours in advance of release. It was a short five sentences and it caught the industry off guard.
Out-of-band releases were very rare and often associated with attacks in the wild. The anti-malware vendors were all scrambling looking for the attacks which up until that point only Microsoft had observed. The technology and telemetry we utilized had given us a crucial insight before wide-spread attacks occurred.
