PiHole

The purpose of this project was to get a deeper understanding of DNS and networking. It also helped with many unix commands.

What is a PiHole?

The Pi-hole is a DNS sinkhole that protects your devices from unwanted content, without installing any client-side software. It can be installed as a docker component or on a raspberry pi.

I had a old raspberry pi sitting around that I had configured for the kids as a retropi, but they were not using it so I decided to do this project to learn something as well as increase the privacy of the entire house. Since getting people to be secure is hard, I’m trying instead to keep the place that they do most of their internet browsing to be more secure.

How to set up a PiHole

I primary used this video and the documentation that they put together. It worked without issue.

How to Create a PiHole

This was a fun and education project because not only did I learn more about DNS. I got to play with setting up DHCP reservations, customizing my DNS servers on the DHCP server. I also never attached the raspberry pi to a monitor or keyboard, I used SSH to connect to it and do all the operations for this tutorial.

I highly recommend this project for fun and for a chance to educate yourself with a hands on project! After setting this all up I learned that my smart TV (Samsung) was sending out 7k request an hour. I wasn’t even using the smart features! We have a AppleTV hooked up to the TV so I just unplugged the Ethernet cable on our TV. It is amazing and surprising to see what request are flowing across your network.

  • Smashing Security – 306: No Fly lists, cell phones, and the end of ransomware riches? – What are prisoners getting up to with mobile phones? Why might ransomware no longer be generating as much revenue for cybercriminals? And how on earth did an airline leave the US government’s “No Fly” list accessible for anyone in the world to download?
  • Malicious Life – You Should Be Afraid of SIM Swaps – If SIM swap stories ever make the news, almost uniformly, they focus on people who lost a lot of money. But SIM swaps also take a psychological toll. Getting cut off from the grid all of a sudden, not knowing why, not being able to call for help. Even when it’s over, you never know if your attackers — whoever they are — will come back again.

Deep Dive on Password Best Practices

On Tuesday, I attended a wonderful talk by Roger Grimes. The title of the webinar was A Master Class on Cybersecurity: Password Best Practices. Roger is very knowledgeable and a great resource for this information, but he talks fast. I really enjoyed the webinar, but it was an hour long and Roger fit a lot in that hour. For those that watch the above free webinar provided by BightTalk and (ISC)2. I thought I would provide some helpful links and videos to follow along in the webinar. First be sure to download the slides from Roger’s talk via BrightTalk.

Roger shows several Kevin Mitnick hacks during the webinar. Here is the No Link or Attachments Necessary hack link, unfortunately its not on youtube, so no embedding. Kevin is the “Chief Hacking Officer” at KnowBe4, the same company that Roger Grimes works at.

After the talk I also looked up my email address on haveibeenpwned.com. No surprises here. My email was in several breaches.

If they have your username they have half the puzzle (assuming you are not using any kind of 2 factor authentication, 2FA, which most are not). Now all they have to do is guess your password. If your password is on this list, Top 200 most common passwords, your screwed, this is exactly the kind of list that hackers will use first.

How do you make a more secure password then. I’ll let Kevin touch on this:

How Easy It Is to Crack Your Password

It is really even easier than that! If you ask chances are people will freely give you their password:

What’s Your Password?

Okay, so let’s assume you are smarter than these folks and you can keep from freely telling people. But can you? You may be doing it, indirectly. According to a research paper from Google, 20% of recovery questions, those you answer when you use the Forgot Password link on every website, can be guessed by a hacker. But while the hacker can do it, 40% of users can’t remember their own according to the paper! When all else fails just review your social media, as 16% of answers can be found there!

My suggestion use a password manager. Then you say, what about LastPass. You have a point, but how often are password managers breached? Not as often as the other 100 sites you use a password to get into. Password managers are still a good choice. In addition to your password manager, why not try some 2FA hardware?

You Should Be Using Yubikeys!

Be safe out there folks!

  • Roger A. Grimes, KnowBe4’s Data-Driven Defense Evangelist – (ISC)2 – A Master Class on Cybersecurity: Password Best Practices01/24/23 – What really makes a “strong” password? And why are you and your end-users continually tortured by them? How do hackers crack your passwords with ease? And what can/should you do to improve your organization’s authentication methods? Password complexity, length, and rotation requirements are the bane of IT departments’ existence and are literally the cause of thousands of data breaches. But it doesn’t have to be that way! –
