Blocking Telemetry in Windows 7 and 8.1

Tuesday, February 21st, 2017

If you’re concerned about privacy, (and have a bit of free time on your hands,) you might want to check out this neat trick for managing Microsoft updates and controlling the sort of information that your system is allowed to share.

Microsoft pushed patches to devices running Windows 7 and 8.1 in recent time that collect information and transfer data to Microsoft regularly. One of the main issues that Windows users may have with telemetry is that Microsoft does not reveal what it is collecting, and what is included when telemetry data is transferred to the company. The following tutorial provides suggestions on limiting Windows data collecting and transferring.

How to Block the Insecure RC4 Cipher in Firefox and Chrome

Tuesday, July 28th, 2015

Yet another browser vulnerability to worry about … but fortunately there’s an easy way to block it.

Whenever you connect to a secure website using Firefox or any other modern browser, negotiations happen in the background that determine what is being used to encrypt the connection. RC4 is a stream cipher that is currently supported by most browsers even though it may only be used as a fallback (if other negotiations fail) or for whitelisted sites. Exploits have come to light in recent time that take advantage of weaknesses in RC4 which allow attackers to run attacks in a reasonable time frame, for instance to decrypt web cookies which often contain authentication information.

Tuesday, July 29th, 2014

This sounds like it could either be very helpful or an invitation to trouble … depending on what you’re trying to download.

Google Chrome, Chromium, and probably the majority of web browsers based on it, come with a security module that scans file downloads automatically. The feature, called Safe Browsing by Google, displays a prompt at the bottom of the browser screen that informs you about malicious files that it. In fact, there are two different messages that may be displayed by Safe Browsing. The first reads “This file appears to be malicious. Are you sure you want to continue” while the second reads “[filename] is malicious, and Chrome has blocked it”.


You Can’t Block Facebook Using Windows 8’s Hosts File

Monday, August 20th, 2012

Well, it turns out that you can after all … but this article still contains useful information in spite of that.

The Windows hosts file offers a great way of blocking or redirecting certain Internet hosts. I’m for instance using it whenever I move websites to a new hosting company to check the life site before the DNS has fully propagated. You can also download software like Hosts Man that allow you to add lists of known malicious sites or advertising servers to the file to block those automatically from being visited on the computer.
