How many times have you seen the list of updates on any given OS and wondered what went wrong? Security patches, bugfixes, upgrades, and even some of the stuff you know you aren't using seems to just need constant babying to keep it operational. Chances are you are using an x86 or x86_64 machine, but even on arm there are plenty of updates - just a bit less often. The reason that many of you don't really hear about is kind of a neat story.Read More

We've all been responsible for something at some point. Website Admins, Linux System Admins, Bake sale operators? Whomever you are you have undoubtedly had at least one experience where something was organized neatly for a reason and had someone come along and screw it up royally by being ID 10 T. In new systems this isn't a massive problem, but on established systems someone with the wrong privilege can ruin quite a bit and quickly. Admins go to great pains to prevent this by believing in education until that fails - which it does in dramatic and costly ways.Read More
Imagine for a moment you keying up serious computer with real muscle. One of those fancy $40,000 Puget Systems jobs. You login to a server and see a distributed network waiting for a command, everything is pristine, a controller GUI - no even better a CLI list in front of you shows which resources on which machine are just waiting for your command. Now of course the question becomes, "Which process on which machine do you actually need to do what?" If what you needed was to solve a massive resource issue, you might need to break it into components and let the machine solve it in Parallels.Read More
Whether you prefer Windows or Linux there are steps you can take to improve your system's security and network topology. Step 1 is always information gathering, and that is true of your host system as well. No matter if you are a Pen Tester or just feeling anxious about people sniffing around your PC, these tools help.Read More
I've rated this device a perfect 5 out of 5 for it's exemplary performance and will list it's specs below.
Processor: Intel Cherry Trail Z8300 Quad Core 1.8GHz Operation System: Pre-installed full edition of Windows 10 Ram: 4GB DDR3L Storage Capability: 64GB GPU: Intel HD Graphics, 12 EUs @200-500 Mhz, single-channel memory One USB3.0 port and two USB 2.0 ports WiFi and Bluetooth 4.0 Built-in Arduino Co-processor: ATmega32u4 Video output: HDMI and MIPI-DSI Onboard touch panel overlay connector Supports 100Mbps Ethernet GPIO: 6 GPIOs from Cherry Trail processor 20 GPIOs from Arduino Leonardo 6 Plug and play Gravity sensor connectors Power: 5v/2A Dimension of board: 88 * 70 mm/ 3.46 * 2.76 inches Packing Size: 110 * 94 * 30 mm/4.33 * 3.70 * 1.18 inches N.W.: 55g G.W.: 100g
Before I go any further I want to say this device gets a well deserved 4.5 out of 5 in my rating system which includes speed, reliability, user friendliness, power consumption, and price. While slightly more expensive than a Raspberry Pi3 it is hands down a better PC replacement in my opinion. It would be suitable for a very wide range of devices and certainly exceeded my expectations in every way.Read More
If you are dual booting Windows, and Linux, chances are that at least once you've been greeted with a broken bootloader, a busybox, or ash shell. If you happen to be dual booting a Debian, Ubuntu, or related distro you can actually fix your bootloader with ease by booting the installer again and run the following from a terminal:
In recent years I've had the opportunity to test and use many of the Linux Distributions, centered around information security. To be clear what I'll be doing in this article is evaluating overall impressions of the distribution, and not the specific tool sets. Many of the tools are suited to many IT tasks and might be confusing to use as a basis for comparison, especially considering they can generally be added to other distributions of Linux. Our evaluation will include overall performance, ease of use, adaptability, and scale, as these are the important factors to consider when selecting a tool for protecting an infrastructure.Read More
Hypothetical scenarios can be annoying when they aren't realistic but have you ever wondered what you would do if you only had one laptop/pc and it fried? How badly would you be setback? Many people deal with this scenario without the added pressure of having anything painfully important to do online, but some have no alternative but to try to get by at least for awhile on nothing but an android device. Lucky for them, and possibly for you, that isn't nearly as bad as you might think.Read More
Mashable mentioned in an article, that Google is looking for hackers to participate in their challenge. The goal is of course to pay out $1000 in addition to the reward from any given app exploited and reported. To quote the article: "Here's how it works. If you find a security vulnerability in one of the participating apps, you can report that vulnerability to the developer, and work with them to fix it. When the problem has been resolved, the Android Security team will pay you $1,000 as a reward, on top of any reward you get from the app developer."
As an example of what they might expect - I'll offer the following:
Whether you are just looking for something to do with a weekend, or are trying to get enough experience with testing to start a career in Cyber Security, practical exercises can be hard to come by. I'll share a few videos here and make a few suggestions, and depending on the questions we get this might become a regular feature here.Read More
Originally posted on my last website version and still accurate as my assessment.
If you haven't begun investigating bitcoin because you weren't sure where to begin, a good place might be coinbase. A fairly typical exchange with paypal access and stringent security that is user friendly enough to get started with.
One of the reasons we like coinbase, is their ability to accept small payouts from experimental mining like small scale cloud mining. Cloud mining involves purchasing hashpower and allocating to a specific cryptocurrency like litecoin, bitcoin, ethereum etc.
On a small scale a $30 investment tends to payout small change daily, but as time goes by some of these allocations can add up/add to other small scale mining efforts. In an article next week we'll probably be going over how to build a small bitcoin mining rig.
Between it's uses for security and visualizations there are more handy snippets of python than I can keep track of. It has become my favorite language for scripting, and possibly for programming in general. I use it constantly. I wanted to include some useful snippets here that you might enjoy, some will be in pdf formats, and I will add more as time goes by.Read More
