Streaming 1080p Video Through The Browser On An Odroid-C2

If your trying to build a video kiosk using a RasperryPi 3 guess what, you can’t and trust me I tried. I stumbled upon the Odroid-C2 and my whole life changed…

To build a 1080p capable video kiosk simply follow the outlined steps below.

  1. Download VideoJS (Open Source Javascript HTML5 Player)
  2. HTML5 Video (.mp4)
  3. Encode your Video at 24/25 fps or at a max of 6Mbps stream, ideally 5Mpbs.

I tested multiple in-browser video players and VideoJS outperformed all. I was able to get movies like The Matrix to play very smooth at even the most GPU intensive scenes. For more information about other methods used or to view the odroid forum thread that dealt with this issue visit here.


Updating To OpenSSL 1.0.2g On Ubuntu Server 12.04 & 14.04 LTS To Stop CVE-2016-0800 (DROWN attack)

It was a bit difficult to find any real information on fixing the latest openSSL CVE-2016-0800 (DROWN attack) so I decided to write this quick post on how to update your Ubuntu Server 12.04/14.04 OpenSSL (or any debian-based distro with apache2) to the latest 1.0.2g build to avoid the DROWN/Heartbleed attacks. I’m not going to go into the details of how the exploit works and how it’s exploited as there are many blogs/sites that already go over this. Instead I will only focus on the fix, I have provided 2 methods, a method using cURL or wget.

cURL Method

  1. sudo apt-get install php5-curl (Install cURL library)
  2. sudo apt-get install make (Install compiling library Make)
  3. curl | tar xz && cd openssl-1.0.2g && sudo ./config && sudo make && sudo make install (single command that will download latest binaries, extract them, cd into the directory, compile configuration and then install the files)
  4. sudo ln -sf /usr/local/ssl/bin/openssl ‘which openssl’ (This will create a sym link to the new binaries)
  5. openssl version -v (Used to check the version of the Current OpenSSL binaries)

wget method

  1. sudo apt-get install make (Install compiling library Make)
  2. wget (Download the latest OpenSSL 1.0.2g binaries)
  3. tar -xzvf openssl-1.0.2g.tar.gz (Extract the tar ball to the local directory)
  4. cd openssl-1.0.2g (Enter extracted OpenSSL directory)
  5. sudo ./config (Configure binaries for compiling)
  6. sudo make install (install configured binaries)
  7. sudo ln -sf /usr/local/ssl/bin/openssl `which openssl` (This will create a sym link to the new binaries)
  8. openssl version -v (Used to check the version of the Current OpenSSL binaries)

This was tested on both Ubuntu Server 12.04 & 14.04 LTS versions. Questions? Comments?

How To Change Network Location On Windows Server 2012 R2

This is one of those quick posts designed more as a note, I had fun trying to find the way to update the network location on my 2012 Server sandbox so I figured I would create a short post on the matter…

It can be found by following:

Server Manager>Tools>Local Security Policy>Network List Manager Policies>Network

This is of course assuming that you have a fresh install with GUI.

If you’re using PowerShell you will want to run the following command (this requires PowerShell 4)

Get-NetConnectionProfile | Set-NetConnectionProfile -NetworkCategory Private

nVidia Shield Tablet Diagnostic Mode On Android Lollipop

I found the Diagnostic mode for the nvidia shield tablet, you can find it at the following path…

Settings > About Tablet

At this screen you want to scroll down to “Kernal version” and tap it numerous times until it goes into diagnostics.

nvidia shield tablet diagnostic mode

This is what it will looks like…



Hope this helps anyone…

Updating To PHP 5.4 On Ubuntu Server 12.04 LTS

If you use php web applications then your know a lot are now demanding to be updated to php 5.4 or higher. To do this in Ubuntu 12.04LTS simply do the following…

If you haven’t already used ppa then you will have to first install python software properties, make sure you’re the root user… ( sudo bash )

apt-get install python-software-properties

PHP 5.4.x run:

add-apt-repository ppa:ondrej/php5-oldstable

PHP 5.5.x run:

add-apt-repository ppa:ondrej/php5

Once you’ve added the repo simply update and upgrade current packages & distribution packages with one simple command :)

apt-get update && apt-get upgrade -y && apt-get dist-upgrade -y

Installing USB Wireless Card On Kali Linux VMware

So I ran into this problem, I installed a fresh copy of Kali Linux onto a VM (VMware) so I could do some pen-testing on my local network without booting into Linux but couldn’t get Kali to use my external wireless card (I needed packet injection capabilities ;))

To make this short and sweet all you have to do to use your external USB wireless card (In My Case an Alfa Card) is just install updated vmware tools (I am assuming you have already added USB Controller in your VM settings…) you can do this by using the following commands on your shell/terminal:

apt-get update
apt-get install open-vm-tools

Once installed you should see your wireless card detecting new networks. This worked on Kali Linux x64 and because its based on Ubuntu Its safe to assume it will work with Ubuntu. Good luck and good hunting ;)

Listing The Last Modified Files In Debian Or Ubuntu

You might be asking yourself why would I care to list the last modified file/s right? Well if your in the security world then you know sometimes it’s important especially in a compromised server/workstation. It’s important to check what files may have been modified to help the attacker, for example, the editing of native configurations or scripts can facilitate permanent access to a system. It’s also important when trying to identify the potential root of the problem.


This command will list all files that were recently modified by without any real order.

ls -t

This command will list all files that were recently modified separating all file names by line by line.

ls -1t

This command will list all files that were recently modified separating all file names by line by line and limiting the amount displayed by 10

ls -1t | tail -10


I am sure there are more aggressive methods but this is a simple one that works pretty solid on any Linux distribution with bash.

How To Spot A Malicious Email

Today I get an email that looks like it came from GoDaddy except for a few things that don’t look right…
Email Headers are not correct, this was obviously a shitty job as the malicious user tried to make the email look like it was coming from godaddy but was actually coming from a compromised wordpress install on Hostgator.

From: Godaddy <>
Message-Id: <>

The Email:

Dear Customer MIGUEL VALLEJO. Confirm Your Identify.

An unknown user was trying to login your GoDaddy account with an incorrect password on Sunday 15 March , 2015 1:05 GMT, and with an unknown DNS IP Location:
(China) ip=, as a result of that we partially blocked your GoDaddy accounts due to major security protocols.

We are sincerely sorry for any inconvenience.

Except for the fact that there is no administrative contact info, phone, business address in the signature it looks somewhat legit. Now Lets look at body of the email specifically at the url and where the link points to…

So this is obviously a malicious email, a targeted one because the user had to go through some effort to put this type of attack together. Sadly this is someone trying to dupe you into coughing up your password or in my case a sad attempt at doing so.
It’s a good idea to go over some security logs after events like this as it could be a sign of someone already in your network and trying to escalate their access.
In my case it was just some noob who though he was dealing with a end user, my response… <^>-_-.

How I Fell In Love With My NVIDIA Shield Tablet…

So I totally ripped myself off, it wasn’t suppose to be that way lol… I traded my ps4 with 2 controllers and two games for what was suppose to be a #nvidia shield tablet  from some guy on craigslist with all accessories. I chatted with the guy for about half an hour and sounded totally legit. When I got home I had more time and light to inspect the tablet which ended up being a 16GB tablet instead of the 32GB version so I was like fml… as I continued I came to two corners which were also cracked, it looked like it had been dropped… FML~… Once I had it reset I tried to play a song and the damn speaker is blown, which sounded fine at low volume… Of course this sucked, I tried calling him back and texting and would get no answer. After about 30 minutes I found out who his name was and where he lived. I decided to say fuck it it’s not worth the drama and the cops would be like “dude! seriously for a ps4?”. So far the tablet is one of my favorite of all tablets I’ve ever owned it’s super fast and running the lollipop OS which is super smooth and responsive. I really want to upgrade to the 32GB so I can have some more room to do some native application development. It sucks that I got jacked but I am happy that I ended up with this tablet it’s perfect :*)

P.S. Hook me up with a 32GB version NVIDIA, I heard it rains tablets at HQ ;) @nvidia #nvidia
