WireShark: “No interfaces found” on Microsoft Windows

When I start Wireshark, sometimes I’m unable to select the network interface to be used to analyze network traffic. I was able to resolve this by restarting a service called “NetGroup Packet Filter Driver“. Please note, this service can not be found in “Computer Management > Services“.

The procedure below can be followed to resolve this:

  1. Open a Command Prompt with administrative privileges.
  2. Execute the command: “sc query npf” and verify if the service is running.
  3. Execute the command: “sc stop npf” followed by the command: “sc start npf“.
  4. Open WireShark and press “F5

Hope this helps!

Secure your Synology NAS with Two Factor Authentication

At home I use a Synology NAS to store all my pictures and documents in a central location. The added value for having a NAS is the ease to access it from everywhere as long as you have an internet connection without ‘the need’ to put everything in public cloud or have it synchronized on all your devices.

I access my NAS by using an HTTPS connection combined with a DynDNS provider. As the web page is open to the internet, I want to protect my NAS by using a more secure approach. This blog article gives you some guidance in configuring Two Factor Authentication on your Synology device.

Securing your FaceBook profile

FaceBook, the social network site known by basically everybody with an internet connection. The numbers of profiles listed on this page, give you a good impression on how really big FaceBook is. At the end of Q4 in 2014, the social media site had approximately 1.35 billion users on FaceBook. That’s a whole lotta people!

Many people seems to forget that it’s a portal between your personal life (pictures, ideas and so on) and the whole wide world. Some time ago a friend of mine told me her FaceBook page got hacked and she felt she was obligated to deactivate her account. I felt it could come in handy to write something about how you can secure your facebook page by implementing some privacy measures, a more secure authentication methodology and some best practices.

Secure your WordPress Blog with two-factor authentication

I recently installed the Google Authenticator application and was astonished you were able to add 3rd party accounts to it. I used the application to secure my Google Account, my FaceBook Account and this personal blog.

Decrypting / recovering mRemote passwords

I just simply love mRemoteNG as a management tool. However they do say all passwords are securely stored! I’ve learned that it’s quiet easy to decrypt them. Just by performing these simple steps:

  1. Open mRemote and go to “Tools” > “External Tools”
  2. Right-click in the white space and choose “New External Tool”
  3. In the External Tools Properties, fill in a “Display Name”, “Filename” and some “arguments”.
    In this scenario I filled in "Password lookup", CMD and "/k echo %password%".
  4. Go to the connection where you would like to reveal the connection and right-click on it and choose “External tools” > “Password lookup.

You successfully decrypted the password:

Advice: keep your mRemote files on a secure location, such as a encrypted stick (with bitlocker or truecrypt).
