What have I been up to?

Well, as promised, I haven't written a post in awhile.  I've been really really busy, so I'll give you a crash course on what I've been doing that's kept me, and thoughts about things that have come to market in the past month or so.

1)  My Mother passed away.  As anyone who has had this happen knows, it's a pretty hard time, emotionally, as well as just, all the stuff you have to do.  Writing your own mother's obituary isn't necessarily a good time.  Selecting what she's going to wear, the casket, ...  just a lot.  The people that have written me and talked to me face to face have been great and I thank you all very much.

2)  VRT.  April 1st I moved to the Vulnerability Research Team at Sourcefire.  I'm one of the many other analysts responsible for writing Snort (and now recently ClamAV!) rules to detect the known, and the unknown.  It's a difficult job, it's challenging, it's fun, and it's busy.  I currently have over 100 bugs in my cue.  Lots of bugs and research to do.  My current focus is Malware and some redesign efforts.  We're trying to make the Snort rules easier to manage and provide more intelligence to the end user as well as increase our coverage in a lot of areas.  Making our rules harder to bypass and more and more adaptable to today's client-based landscape.  Over the rest of 2011, the VRT ruleset is going to change, for the better, and significantly.  There's essentially going to be three steps to this, and I'll post about the changes soon over on the Snort Blog.

3)  Snort Community.  It's growing.  When I took over the job in October of last year, I thought the Snort community had reached critical mass.  Most open source projects that I've seen plateau after awhile.  When I was running the BASE project we got up to about 15k downloads a day, and that was our plateau.  But since I took over, I've started to keep a lot of metrics.  Metrics about email postings, forum postings, users, downloads, etc.  Lots of metrics.  They are all going up.  We're doing well.

4)  Snort.  It's changing and evolving.  We're rolling out 2.9.1 soon with some very significant changes (read about PAF!) in detection and the IP reputation preprocessor.  The changes we have planned for post 2.9.1 make Snort even faster (we are already hitting WAY over 20 G/sec in detection, and the next number we are aiming for is unheard of in our industry), and easier to deploy.  Changes in it's detection will make it more accurate and significantly increase the effectiveness of our rules and keywords.

5)  ClamAV.  Also growing.  Now built into Immunet 3.0 (the company we acquired in December of last year) providing not only cloud based detection (so awesome), and offline detection.  Immunet is growing very fast by the looks of our daily metrics which means ClamAV use is increasing as well.  OEM solutions that are building ClamAV are also growing, and now recently we are going to start accepting community virus detection as well.  This will grow our detection rate exponentially.

6)  OSX Lion.  It's out.  I'm using it (have been for about a month and a half).  It works great.  The only thing I don't like about it is the deletion of the scroll bar.  I don't mind it as much as my wife will (I haven't converted her yet).

7)  Defcon.  We'll (VRT) be there.  Look for us in pink.  For those of you that were able to get an invite to TheBarCon, we'll see you there.

I can't think of anything more right now, and am being summoned for dinner.  I'll write more when I have a chance. If you have any questions, leave a comment below.

Hackinations: 5 really good Lion tweaks | TUAW - The Unofficial Apple Weblog

Hackinations: 5 really good Lion tweaks | TUAW - The Unofficial Apple Weblog

I know I haven't written in awhile, I have a blog post planned in my head, just have been too busy to put it down on paper. But in the meantime, I saw this article and thought it was pretty good for you OSX readers that have upgraded to Lion.

Mac OS X Lion beta reveals "Restart to Safari" browser-only mode

Mac OS X Lion beta reveals "Restart to Safari" browser-only mode

From Engadget.

As the article says, in OSX Lion there is apparently a way to reboot your machine into "browser only" mode. Could be useful in a couple of situations.

A) If you are going to leave your computer unattended, maybe at home, and you want to allow people to check their email.
B) Kiosk mode. Maybe a computer sitting in a public area?

I don't think they are going for a play against ChromeOS here as the article sort of implies. Either way, interesting.

Apple's "known bad" Xprotect file is now automatically updated

Very technical term I used there in the subject.. I know.

Apple just released Security Update 2011-003, in which they check for the MacDefender Malware, which I wrote about here.  But the most interesting part of the update is this paragraph:

File Quarantine
Available for:  Mac OS X v10.6.7, Mac OS X Server v10.6.7
Impact:  Automatically update the known malware definitions
Description:  The system will check daily for updates to the File
Quarantine malware definition list. An opt-out capability is provided
via the "Automatically update safe downloads list" checkbox in Security Preferences. Additional information is available in this.
Knowledge Base article: http://support.apple.com/kb/HT4651
Where apparently, Apple has built in an automatic updater to their anti-malware file, in it's most basic form, giving Apple the ability to directly protect their OS against the newest Malware.

If you don't know what I am talking about when I say "anti-malware file"  I suggest you read this post as well.

Speaking Engagements

This past week I was invited to come speak at ISOI9 in Sterling, VA.  The talk seemed to go over rather well, and while I didn't get a lot of questions in the presentation, I got a ton of questions afterwards out in the hall.

This coming week I'll be down at the Richmond Area Virginia Linux User Group.  The coordinators of the group were kind enough to invite me down to talk about Sourcefire and the OpenSource company that we are.

If you are in the Richmond, VA area, be sure and come out!

I have another speaking engagement in August as well, but I'll blog about that when it gets a bit closer to the time.

If you are interested in coming to the meeting this week, it's on Tuesday, May 17th at 6pm.

Locking your screen on OSX

Friend of mine tipped me to this (thanks @englishlfc).  People have asked me in the past about this, basically, how to lock your screen (Start your screen saver) using a keyboard shortcut on OSX.

On Windows you can mash Windows-L and it will lock your screen.  Or Ctrl-alt-del, enter.  (God it pains me to watch people hit Ctrl-Alt-Del and then MOUSE to "Lock Screen"... GRR!!)

My solution in OSX has always been to set my bottom left corner of my screen to "activate screen saver".  Then I could just move my mouse to that corner, and viola, locked screen.

But @englishlfc was looking to the same thing with the keyboard, and there are a ton of ways of doing it in Applescript, but it's even easier with Automator.

So, go open Automator, and select new "Workflow".

You'll get a blank screen that looks like this:


Select "Utilities on the left, and then find "Start Screen Saver" in the next column:


Drag "Start Screen Saver" over to the right:


That's it.  Save it as an "Application" in Documents or Applications.

Then go to System Preferences and set up a Keyboard Shortcut to activate that App:


Simple.

I did it a bit differently.  I used Alfred's new "Global Keyboard Shortcut" functionality to activate the app.


Done.

Maybe this'll help someone.

Want to know how to do this in Applescript?

First 2011 Snort Webcast Registration is Open!

Just wanted to announce that Registration for the first 2011 Snort Webcast is now open at the following link:

https://sourcefire.webex.com/sourcefire/onstage/g.php?t=a&d=793571014

Our Presenter is Nick Moore of Sourcefire and he'll be presenting the first of a two part series on simply getting started with Snort.  How to set it up, running, and working with traffic.

When you click on the above link, you will see a "Register" link on the left-hand side of the page.  Click that for pre-registration.

What does pre-registration get you?  Reminders.  You'll receive a reminder the 11th (Monday) and an hour before we begin so you'll be sure to remember to attend.

The registration form only asks for a couple things so we can remind you about the event.  Registering for the event does not mean that you will start to receive sales information, we're simply using the information for numbers (how many registered, how many attended) information.

Topic: Snort Webinar Training
Date and Time:
April 13, 2011 11:00 am, Eastern Daylight Time (New York, GMT-04:00)
Event number: 793 571 014

Thanks!

Time to move on to a new job.

For the past, almost 6 years, my employment at Sourcefire has been great.  I've worked in Professional Services, going around to over 150 customers, educating them on Sourcefire, the product, the GUI, detection, and all the awesome that is, but..... it's time for me to move on.

I accepted a position last October with Sourcefire, being in charge of OpenSource Community Management, in charge of coordinating the communities themselves and being the liaison between the communities and the company (Sourcefire) for all OpenSource products.  This has been great.

Well, I'm pleased to announce that, I am retaining this new role as I go, so I will still be the OpenSource Community Manager for Sourcefire.  

Where am I moving to?  A company you may have heard of:
Sourcefire.

That's right, I'm staying right here.  Effective today, I'm moving out of Sourcefire's Professional Services team and moving to the Vulnerability Research Team (VRT), the team at Sourcefire that is responsible for publishing detection for Snort, ClamAV, and Razorback.

My new role has me writing detection for Snort primarily, moving into writing detection for ClamAV and even vulnerability research down the road.

I'm pretty excited about this move, as you can probably tell, and look forward to working with my new team.  

P.S.  I know I write this on April 1, but it's not an April Fools joke ;)

To the Cloud! (with the blog)

Some of you may have noticed that my blog looks a bit different.  

I moved it from my own server and put it up on Google's Blogger hosting service.  I had it up on Blogger about a year ago, and in retrospect can't think of why I took it and put it on my own server.  Experimenting I guess.

In the meantime there are going to be a lot of 404 links for really long url's and url's that have strange characters in them.  They'll 404 themselves out of the search engines and be reindexed soon I hope, so I'm not too terribly concerned.  

If you came to my blog on a search query (which about 50% of you do), and your search resulted in a 404, then take a look at the archives, or use the search box.

Suspicious Domains related to Japan Disaster

With every disaster that takes place, one of things that I do is start to watch the domain names being registered on the internet in relation to the event.

For instance, "earthquake", "Tsunami", Haiti, Chile, and now, Japan.

We mourn for all of those that lost loves ones in each of the disasters, and I feel very sorry for those that have lost everything.  Homes, cars, valuable pictures of your loved ones, family history, and the families themselves.  I am quite sure there are examples where entire families may have been lost to this most recent tragedy.

It's despicable that a malicious person would register a domain, and set up a webpage to receive donations, only to keep the money themselves, or fund $bad_thing.  Absolutely disgusting.

I was taking a look through my list for this morning (I get a list every day), and looking at some of the examples.  A lot of the names you wouldn't even think, just by looking it, that it would be bad.  Examples like "redcrossjapan.com" and .org.  One might think that was a legitimate site.  A few more interesting ones, I'll leave the extension off of these:

  • "earthquakeandtsunamis"

  • "tsunamidanger"

  • "tsunamireliefforjapan"

  • "savejapanesepeople"

  • "rebuildjapan"

  • "japanemergency"

  • "japanliferescue"

  • "earthquakeeastjapan"


Now, I'm not implying that any of the above are bad or linked to the evil-doers. I'm saying that you need to use caution when donating and visiting these sites.  Not all humans are decent, wholesome, and good.  In fact, there are a large amount of people that aren't.  I know, surprise, surprise.

How many domains have I see like this?  Hundreds.  Several.  Hundred.

Donate


I don't want to dissuade you from donating funds to the people of Japan.  They need your help.  They need it bad.  I've donated, and will donate more.  But ensure, when you are donating, you are donating to a reputible organization.  People flocked to help Haiti, I'm asking that we flock to help Japan too.  Just because they are not a 3rd world country, doesn't make them any less important.  Japan came to our rescue when Hurricane Katrina hit, donating millions and millions of man hours and dollars towards the tragedy.  Let's do the same for them.

Mac OS X Lion iChat supports Yahoo Messenger video and voice chat

As the title of the article title states, Apple's OSX iChat client on OSX 7 Lion supports Yahoo Instant Messenger adding to support for AIM, GChat, and standard Jabber.

This is a welcome addition and stands to keep chipping away at the other major Instant Messenger clients, but, why is there two separate video chat clients for the Mac? (Facetime, iChat)

It would seem to me that it would make more sense to combine these two.

  • Facetime traverses NAT (etc) better than iChat

  • Facetime uses less bandwith

  • Facetime is now "HD" (as Apple calls it), leaving the "quality" issue behind (iChat's resolution was better than Facetime, as Facetime is faster on the network)

  • However, iChat does support up to 3 video calls at once (and like, 10 audio)


Anyway, I hope they fix this before OSX 7 is released finally.  I'd love to have one app that covered both IM and Mobile Video Chat.

Appleinsider has a great breakdown featuring some nice videos of OSX7 on their site here and here.  Check it out if you are an Apple user like me.

Other notable features of OSX7 I think:

  • No Front Row

  • Java runtime is not installed by default, it's a download now.

  • Rosetta support (so support for running PowerPC apps on Intel machines) is gone.  Meaning that Apps should be smaller in size.

  • Migration Assistant now supports helping Windows users move over to the Mac (smart)

  • OSX Lion was given to a few researchers for review, so they can beat it up.  Very nice work.  I hope Apple rewards the researchers in some way.

Rude People

Okay, so there I am waiting in line, directly between two people, and I am sitting on my suitcase. The lady in front of me has a space between her and the person in front of her of about 4 feet. Plainly visible. No excuses.

So this guy decides to take it upon himself to try and cross the line, not in the big ass 4 foot space that everyone else crossing the line is passing through, but directly between me and the lady in front of me. Rudely.

He squeezes by in such a way where he bumps my suitcase, sending it, and me crashing to the floor where I wind up on my ass.

He starts to apologize profusely.

I get up, say nothing, and sit back down on my suitcase.

He proceeds to apologize again, he looks around, looks at his ticket, then walks BACK through the line, in the big ass 4 foot space.

H.264 is being dropped from Chrome

Chromium Blog: HTML Video Codec Support in Chrome.

Key sentence from above article:

"Though H.264 plays an important role in video, as our goal is to enable open innovation, support for the codec will be removed and our resources directed towards completely open codec technologies."

Key comment from Slashdot on above article:

"This serves two strategic purposes for Google. First, it advances a codec that’s de facto controlled by Google at the expense of a codec that is a legitimate open standard controlled by a multi-vendor governance process managed by reputable international standards bodies. (“Open source” != “open standard”.) And second, it will slow the transition to HTML5 and away from Flash by creating more confusion about which codec to use for HTML5 video, which benefits Google by hurting Apple (since Apple doesn’t want to support Flash), but also sucks for users."

Google, just when I started to like you again.  I turned away from you for about a year and a half because you pissed me off with the Buzz thing.  Now you go and do this.

One step forward, two steps back.

iPhone 4 goes to Verizon too.

Finally, after long last, the iPhone is coming to Verizon.

I probably could go on Ad nausem about the new iPhone, but I'll just cover the bullet points

  • The antenna is redesigned, and as a result the buttons are moved slightly down on the left, so some cases may not fit.

  • CDMA, not LTE.  Which means you can't talk and surf at the same time. (Feature that I use a lot)

  • You can use the iPhone as a wifi hotspot (so like a mifi) for up to 5 devices.  Nice.

  • Coming February 10th for GA.  Advanced ordering for Verizon Customers on Feb 3.

  • Otherwise, it's the iPhone 4.


This will be nice.

A Year in Reflection

I am reading all these posts on reflection on 2010 and accomplishments for this year.

Yes, I accomplished a lot for this year.  Lots and Lots of work stuff.  But I accomplished one thing that eclipses all else.

I have a beautiful family with an awesome wife and two beautiful kids.

Happy New Year everyone.  Well wishes for 2011.

Whew, what a whirlwind

Talk about a busy end of the year, so on top of going my actual consulting gigs for customers, I am also doing the other full time job I have of the Snort Community Manager. If you read my blog, you've known this.

So, what have I worked on so far.

  • Snort Twitter account. Not really a lot of work here, other than getting Twitter to remove it from the parker's clutches and give it to us.

  • Snort Blog. Getting this set up, with the DNS entries, blog posts, editing, writing, design, and even the banner image (thanks CC for that!) was about 3 weeks worth of work.  Check it out http://blog.snort.org

  • Snort Mailing list/Forum Consolidation. I thought it best to let the Community decide, so I made a non-scientific poll to choose between the forums, the mailing lists, or the penultimate solution, to merge the two. Thought of Google Groups for this. Google Groups allows you to post like a forum, and post like a mailing lists, and Google Groups takes care of the arrangement, merging, and threading. Very nice. I had this all set up, and was preparing for everyone to start making the move over to Google Groups, and we came up with another idea. So we're working that angle right now (stay tuned).

  • Snort Subscriptions. Been doing a bit of backend work on Snort subscriptions, trying to figure out how to work this out to be a more streamlined process and eliminate a lot of the headache and purchasing obstacles for our users. Concept work mostly.  Also talking about VRT Subscriptions with various members of the legal team and VRT.

  • ClamAV subscriptions. Working on what we are doing and going to do for certified ClamAV code.

  • Code licensing. Meetings with our legal team!

  • Writing articles for magazines and getting ready for speaking engagements in 2011. Pretty much what it says.

  • Laying the groundwork for webcasts and Snort User Group Meetings. Going to fire these up in 2011 again. Several Snort User Group meetings are wanting to start back up. Great to see that there is a lot of interest for our community.

  • Bug filing and progress. What I've started doing is, if bug reports come in via various methods of bug reports, I take them in, triage them, put them into bugzilla, and provide feedback to the people that filed the bugs. This seems to be working quite well right now.

  • Working with our Web-team on any Snort.org issues. Pretty much what it sounds like.

  • Fixing Snort.org. For instance, I rearranged the http://www.snort.org/docs link. To bring the content that people are looking for the most to the front page. Also it was brought to my attention that we had a bunch of W3C html coding errors. I went through and fixed about 40+ of these.  Along with about 100 other barely seen or noticed changes to Snort.org in order to bring the good content to the front, and the content that is barely used to the back (or done away with).

  • Internal VRT Subscriptions. It was brought to my attention that several people that work at Sourcefire apparently didn't have access to the VRT rules (like they should have).  Had to fix that!


Had an email that today that asked me about all these new "news" dissemination  methods that we are standing up and is it going to create confusion.  That's probably a blog post left for the Snort.org blog.

Snort has a Twitter account

Another post for my Snort/IDS audience that read my blog.

We managed to get a hold of the "Snort" account on Twitter.  Someone was simply squatting on the name, not using it, so Twitter has a way of petitioning to get a hold of a name for a bunch of different reasons.  So we got with Twitter and they freed up the @Snort Twitter name for us.

Using the @Snort Twitter account we'll post new news, upcoming items, blog posts, news about Snort and interesting other tidbits that may or may not be found anywhere else on Snort.org

Check it out, follow us:  http://twitter.com/Snort.  Thanks!
