In this post is where I have posted my Penguicon 2016 - Internet Security For the Lay Geek talk. It took place on April 30th at 5pm at Penguicon in Southfield Michigan. The internet is a place full of wonder and excitement for all people. It is a great place to for education and collaboration. While there is great opportunities to learn from people all over the world you will may also fall pray to malicious people too. Here I propose 5 steps you can take to reduce the likely hood of an attack.
- Get an AntiVirus/AntiSpyware/Firewall
- Install updates or remove programs
- Use strong unique passwords
- Turn on Two Factor
- Watch out for scammers
- Don't use login links in emails
- Don't over share on Social Media
The information in this presentation is intended for educational use only. Techniques shown should only be performed on your own network. Using these skills on a network without prior consent is illegal. (Don't be evil) In this talk I present on the techniques that hackers use and how to keep your self safe.

I decided I wanted to start playing with IPV6. to do it with out native IPV6 you need to have a tunnel to a Tunnel Broker. I have herd from a lot of people that Hurricate Electric is a good one to use.
I recently had to cleanup some websites where some of the wordpress files were changed. I was able to clean the files by using a few scripts. The first one looks through all the files looking for base64 php code: base64-check.sh
Here is my presentation given at Penguicon 2014 on May 3rd 2014. http://bemushosting.com/present/PGP-GPG_Pen14.html In this presentation I cover these subjects:
- Why Encryption
- Whys and Hows of PGP/GPG
- GPG setup and maintenance on linux
- Privacy through Encryption
- Getting you key signed
- Using GPG for secure communication
To get started you will need to create a gpg key and put it on a key server. There are many key servers available, so choose one that people will be able to use. My key is available on the https://sks-keyservers.net/i/ There are some GUI or point and click programs available and here are two common ones. These programs will allow you to create, export, update, sign, send and sync with the servers. In Linux Mint there are three servers configured by default: Ubuntu, SKS, and PGP.com.
