AnyCon 2017 Review

I will preface this review by stating that putting on such events is by far not an easy task.  There is a ton of planning that goes into these.  On the day of the event not everything will go as planned and you will have to improvise.  Speakers will pull out, a sponsor may not deliver, or your CTF has a bunch of technical problems.  But you push through and rely on your team to help you through it.

On to the review…

This past weekend I was able to attend the first annual AnyCon security conference which took place at the Albany Capitol Center.  Overall, it was not a bad conference for a first time run.  It was the typical large conference setup with keynotes from Dave Kennedy (TrustedSec, Binary Defense, DerbyCon) and Sanjay Goel (University of Albany).  There were three tracks – Offensive, Defensive, and Educational.  For the full track listing you can hit the site up http://www.anycon.info/agenda/.  In between the talks you could head over to their onsite CTF, hardware hacking village, or play some ping pong.

The Content – As expected for a first run conference.

It was your typical set of conference talks.  Irongeek (Adrian Crenshaw) has them all posted up on his YouTube Channel.  I will let you be the judge of their quality.  Some of the talks certainly showed that pool of submitted content was not very deep and no real due diligence was done to vet the speakers.  One speaker, in fact, claimed during his talk that he single-handedly brought down the Teslacrypt C2 servers and forced the attackers to cease their DDoS attacks on his employer’s network.  That prompted some investigation by conference attendees on the legitimacy of the speaker, there is a pretty entertaining thread on Twitter.  But these things happen and will continue to happen so long as proper vetting isn’t done.  But as a first run conference, you can’t be too picky.  Speakers are not exactly knocking down your door to get accepted.  But that all comes with time.

It was pretty clear their target audience was not the seasoned professional, but that is ok.  In fact, you are hoping that those guys and gals will fill in your talk slots.  There were a good number of students attending which, I think, is great!  Hopefully they came away with more than I did from the conference and will continue to grow their skills and get out to some of the bigger conferences.

The Cost – No swag, no food, what did my 125 bucks get me?

When deciding to put on such an event, the topic of cost will be a big piece of the puzzle.  The goal should be to keep the cost low for the attendees.  Not many people are going to want shell out a ton of cash for a first run conference.  Even with the cost of $125 for a non-student, I still registered to attend as I am an avid supporter of furthering the education of the community and Albany is not a far drive.  Unfortunately, I left the conferencing wondering what I actually paid for?  I didn’t get any real swag besides what was available at the vendor tables, no free conference t-shirt, the badge was a basic plastic card badge, there was no breakfast or lunch provided on either day.  I’ve attended BSides events with a much lower cost to register ($20 or less) that included a t-shirt, breakfast, and lunch.  That is what your sponsors are for!  Your purpose for this first run conference should be to get people in the door so that they will come back next year.  As your conference grows you can bump the cost up as the demand to attend may increase.  Now, thankfully, not everyone had to pay the higher cost.  Students were offered a $50 ticket, still pretty high in my opinion.  Hopefully they pay attention to their feedback survey and work to bring the costs down or at least offer more to justify it.

Other thoughts…

Time management certainly needs some improvement.  It did not appear that any of the talks had a time keeper.  This caused the more long-winded speakers to go well over their allotted time which ate into the next speaker’s block.  Things like this can certainly throw off the whole schedule if your talks are tight.  But you will luck out during these first runs by the less experience speaker ending early.  After the keynote on Friday, there was little direction from the conference organizers on logistics.  There was no mentioning of lunch possibilities or plans for later that evening.  We were kind of left to figure that out on our own.  You need to assume that there may be a fair amount of people coming in from outside the area.  You don’t need to have a big party but you should look to the sponsors for possibly hosting a happy hour.  After the last talk, attendees just sort of went off on their own as they were not sure what else to do.  Again, if I was paying $20 bucks for a BSides event, it probably wouldn’t be a big deal, but this was close to the same price as DerbyCon but with a fraction of the content.

Summary of suggestions for next year:

  • Better time management.
  • Better vetting of speakers – don’t pollute the minds of the young by subjecting them to charlatans!
  • Swag bag – give me something to take back with me other than your event program!
  • Food, at least cover breakfast for those driving in the morning of the event.
  • Keep in contact with the attendees throughout the event, not just at the beginning and the end.
  • Look at adding a lock picking village separate from the Hardware hacking village.
  • Make the CTF an internet based one so people can work on it from their hotel rooms.

InfoSec Career “Quick-start” guide

  1. Install Kali
  2. Pwn all the things
  3. Collect big paycheck!

So what I really want to accomplish with this post is to provide a series of sources to help you get going in your infosec career.  I had a much longer post going on about building a good base of other technical skills and such but lets just get to the meat of it.

Online Training

Free Resources:

  • Codecademy – Offers a number of free courses with added features if you upgrade to a pro subscription.  Great place to learn Python and Ruby.
  • Udacity – Much wider selection of programming courses, possibly better place to start for you App Sec types.
  • Microsoft Virtual Academy – Yes, even MS has a ton of free training resources.  Powershell to .NET C#!

Paid Sources

  • PluralSight – 30 bucks a month and a free trial.  They cover a wide variety of topics from CISSP to OWASP Top 10 for .NET with Troy Hunt.
  • ITProTV – Covers a wide variety of content spanning IT, probably a good place to start if you need to build up those base skills.  A bit pricier than PluralSight but has a stronger focus on IT in general.  Also you can probably find a discount code if you listen to Paul’s Security Weekly.

Podcasts

  • Security Weekly – They have expanded beyond the initial Security Weekly podcast to cover Enterprise, Startups, and Securing your digital life.  Listen to them all or pick and choose!  The team is great and you can’t go wrong, they will get you asking “What is the problem we are trying to solve??”
  • Risky Business – Covers the weekly security news from an Aussie perspective and includes special segments and interviews.
  • Southern Fried Security – Weekly-ish topical security discussions from the south.
  • SANS Internet Storm Center (ISC) – a quick 5-7 minute daily micro-cast covering security highlights.

Social Media

Twitter – Pretty much start with the people who host the above podcasts and the ones followed by our twitter account.  It is a great place to start interacting with the active security community.

Conferences / Meetups

  • Security BSides –  Spawned out of rejected CFPs from Blackhat 2009, Security BSides has evolved into a global series of events put on by local security communities.  This is a great place to get your feet wet and the cost is free to minimal.
  • DerbyCon –  5 day con down in Louisville, KY.  One of my personal favorites if you can fly and afford the hotel.  If you are in a reasonable distance you can also drive.  They have 2 days of training sessions before the actual conference.  It is a more intimate conference compared to the likes of DEF CON.  They also include nightly activities and a CTF that has something for all skill levels.  When you are there make sure to stop by the hardware hacking and lockpick villages!
  • CircleCity Con – I can’t speak on this one but the organizers are a great bunch.  If you can get to Indianapolis in June, check this one out!
  • Thotcon – another small con, it already happened this year but put it on your calendar for next year if you are going to be in the Chicago area.
  • DEFCON – Can’t mention the others without mentioning this one.  Without Blackhat and DEFCON we would not have the community that we have now.  I have yet to attend either of these but it is on the bucket list.
  • Meetups – Google search for local groups in your area.  Check around at Maker and Hacker spaces.

Other Resources

So that is it for now, hopefully you found this useful.  If you have other resources you come across feel free to message me on twitter and I will post an updated list.  Good luck and remember, if you are looking for your first official security gig, don’t be afraid to apply even if you think you are not qualified.  The smart employers may look past the lack of skills if you can demonstrate the right mindset for this work.

 

BSidesCT Azure Security Talk

As I sit here on the nice shady patio enjoying my morning coffee, I figured I should probably post up my slide deck from my first official talk.  First of all BSidesCT was great!  The organizers made some classy laser cut badges this year and the CTF was a good time (actually got 4th in it!).  Will I submit another?  Who knows?  I think I will build on it a bit and learn more about ASP.NET in the process.  Ok, on to the side deck as my yard work is calling (thought I took Friday off for fun?)

Of Course My Cloud App is Secure, It’s in Azure

Some notes to add to the deck when it comes to the logging Azure Websites:

  • Azure has added the ability to bring log files down via FTP/FTPS.
  • They have added other log tools such as Log Stream which lets you watch your application and web log activity.
  • Azure PowerShell can do it using get-azurewebsitelog –name <appname> -Tail
  • Azure Powershell can do it with save-azurewebsitelogSaves to zip in directory you run the command from.

Other items to note when moving to any cloud solution:

  • Many security features are not enabled by default, though Microsoft does notify you of certain ones to turn on through Security Center
  • You can encrypt your Azure SQL Databases!
  • You can enable 2FA for your Azure/Live Account as well as implementing it within Azure for Azure AD or Web Apps.
  • Review your SLAs!!!
  • And of course way the risks of any cloud service.  Not all data is created equal and some of it is better off staying on-premise.

OK the temp is rising and it isn’t even noon yet, the yard awaits!

Anatomy of a Javascript Downloader

So one of your users got an email from a supposed vendor with an attached invoice.  The invoice wasn’t a PDF, word doc, or even an excel sheet.  It was a zip file, and the user opened it as well as opening the “.js” attachment.  Now they called you explaining that they can no longer open any files on their computer or their network share.  The files have all been renamed and the user  has no idea what the heck happened.  You already have a good idea that they downloaded some type of crypto ransomware.  But how did it get through??  You thought you had adequate protection with antivirus as well as web/email filtering.  After chatting with the user, you were able to obtain the original email that she opened unfortunately there wasn’t much you could get from it.  The email address it came from was most likely compromised, so you added it to your anti-spam black list.  You noticed a bunch of files in the zip but when you tried to look at them in notepad it was just a big blob of code that didn’t make sense.

Fig. 1 raw javascript file

There are only a few areas that might look like readable code, but most of the file is what we call “obfuscated”.  The malware author encoded most of the code which helps prevent typical anti-virus software from picking up on the malicious parts.  Also this is javascript which could also be used for legitimate purposes.  At this point you could submit the samples to your AV vendor so they could update their definitions and protect the rest of your users from infection.  You can also upload them to Virustotal.com. But what does this file really do?  It is obfuscated so most online analysis tools may not be able to pick up on the actual instructions.  These javascript files are usually just the delivery method for the cryptoware and that is where Remnux comes in to help.

REMnux-logoRemnux is a Linux toolkit for reverse engineering and analyzing malware. It has a number of different analysis tools to assist in malware analysis.  One of my favorites for handling these types of files is JSDetox.  This is a docker based app that will analyze the messy javascript code seen in Fig. 1.  In order to start it up, just type JSDetox in a terminal window.  It will then instruct you on how to start the Docker image (See Fig. 2.).  Once it starts up you will then be able to connect to http://localhost:3000.

Fig. 2 JSDetox Startup

Fig. 3 JSDetox Dashboard

Open the browser in Remnux and connect to http://localhost:3000.  You will then need to upload the obfuscated javascript file in order to complete analysis.  Simply click the “Upload” button and choose the bad JS file.  If you click the “Reformat” button, it will organize the Javascript code into a more structured layout.  Unfortunately this will not deobfuscate the code.  (See Fig 4.)

Detoxed Javascript Code

Now lets make some sense of it!  Click on “Analyze” then scroll down to look at the deobfuscated javascript code (See Fig. 5).  It begins to make a little more sense right?  The code builds out a number of variables that are then put together further down via instructions.  What it eventually does is calls out to a URL using a GET request.  It downloads and runs an executable in the computer’s default TEMP directory (See Fig 6).

Fig 6. Instructions

Fig 6. Instructions

At this point you can examine other systems for possible infection by looking for the executable file in the temp directory.  You can also take the URL and add it to your web filter block list.  You should also check your email service to ensure you can block such files from making it to your users.  Google Apps does a pretty good job at blocking these types of messages.  Microsoft Exchange requires a bit of magic with Transport rules as it’s default Exchange Online Protection service doesn’t block .js files nor does it look inside zip files.  If you have some form of anti-spam or email gateway security solution in place, it should prevent these as well.  But if you are a small business, you may not be so lucky to have a budget for such things.  Good luck and happy hunting!!

Update 5/6/2017

As a follow-up to this post, you can also look at using a group policy to set the default application for javascript files.  Currently it is set to open with the Microsoft Windows Script Based Host (wscript.exe).  Set js files to open with Notepad and they won’t execute.  That being said, always verify that production applications are not utilizing local javascript or else you may have a bad day.  I have never seen anything in my travels that would justify such things but you never know.

Goings on in and around the Nutmeg State…

Apologies for not posting anything in a while.  Hopefully that will change over the next couple weeks.  We will keep it simple and this will just be a simple events posting…

Regarding the Dell Security Bug

First of all read up on the details over at Krebs On Security.  He has a pretty good explanation as to what Dell did as well as additional reference sites on the matter.  The Reddit discussion in the reference section has some good technical details.  But what does all this mean to the regular folks out there who buy their Dell laptops and like to enjoy their drink while using the free wi-fi at the local coffee shop?   Continue reading

Humans Need Not Apply

Watched this video this morning and it reminded me of a time when I went to visit a relative in the hospital.  I noticed the hallway had a number of small antennas sticking out of the ceiling every few feet.  I figured “Hey that’s some pretty extreme wi-fi coverage!”  A few minutes later an automated medicine cabinet came rolling down the hallway.  It stopped at every room and dispensed meds to the patients.  If you stood in front of it, it would wait for you to move before continuing.  And this was probably over 5 years ago!  So yes the age of automation is clearly underway.

So this post may not be very security focused, but it will apply to us just as much as it applies to the nurse or pharmacy tech that was replaced by that robot.  As costs go down to utilize automated bots (both software and hardware) so does the need for humans in those positions.  The video covers it well, so take the 15 minutes to watch.  In IT we are seeing this happen on a regular basis, hell some of us probably wrote some nifty scheduled tasks to free us up from doing all those repetitive sys admin jobs.  We may have even written someone out of a job by automating the management of users.  And we certainly should because that frees us up for concentrating on more long term goals, upgrade plans, new hardening techniques… etc.  Heck, back in the day, it would take us weeks to bring a new server online, fully patched, hardened and tested.  Now I can log into AWS or Azure and spin entire remote AD environment up in a couple hours (depending on specs).  That includes a site-to-site VPN with the virtual network I just setup as well.  All that could even be automated as all of it can be done through Powershell.  As for testing the systems, well that is also being automated more and more.  Netflix employs their Chaos Monkey to bring systems down during business hours so that they can make sure their apps continue running if such a thing happens when no one is around to fix.

So the days of clicking “Next.. Next.. Next… Finish” are over.  If you are not picking up a scripting language to help with your job or learning to make LEDs blink on the breadboard, you may become obsolete.  If you have kids, it would be wise to push them towards the math and sciences.  Get them Lego Mindstorm sets!  Show them Codecademy!  Bring them to a maker fair and let them see the cool things done with 3D printers, laser-cutters, and robots!  We once taught a bunch of kids how to pick locks, don’t worry we told their parents that locks don’t work anyway.

So the bots are coming, you could either be the one creating them or the one being replaced by them.  Either way, the years to come will be interesting!

Apologize for lack of Activity

Due to some issues with time, availability and overall meetup participation, I have chosen to close out the meetup site. At the end of September it will be shutdown. From this point on any Nutmeg InfoSec activities will be announced here and on the twitter page.

I still believe there are people out there who enjoy discussing and collaborating on InfoSec and hackery.  If you need your fix of hacking and geeking out head over to NESIT Hackerspace.  They typically have public nights on Monday/Wednesday.  Activities include hardware hacking, 3D printing, woodworking, and even cooking.  I once learned to make LEDs blink using Arduino!

So keep an eye out here for any possible meetups or events.  Until then check out Security BSides for upcoming local events.  These are a great events to meet others in the InfoSec community, not to mention the talks are top notch and you usually don’t have to wade through thousands of people to get into. They also cost very little to attend.

RTFM – Installing the update doesn’t automatically fix the vulnerability

Recently I was going through my vulnerability scan report and noticed one of the top 5 plugins was in regards to MS15-011.  Reading through the report it mentioned that the patch KB3000483 was installed but UNC Hardened Access was not enabled via Group Policy.  After further reading of the KB article, I realized what needed to be done.  Microsoft was nice to give some recommendations and such.  So I enabled the UNC Hardened Access on the SYSVOL and NETLOGON shares for the domain.  I did not do it for the file shares as we tend to use multiple OS platforms.  Though I would recommend doing so if you are running in a single platform environment (All Windows).
