Law Enforcement Appliance Subverts SSL | Threat Level | Wired.com



That little lock on your browser window indicating you are communicating securely with your bank or e-mail account may not always mean what you think its means.


Normally when a user visits a secure website, such as Bank of America, Gmail, PayPal or eBay, the browser examines the website’s certificate to verify its authenticity.


At a recent wiretapping convention, however, security researcher Chris Soghoian discovered that a small company was marketing internet spying boxes to the feds. The boxes were designed to intercept those communications — without breaking the encryption — by using forged security certificates, instead of the real ones that websites use to verify secure connections. To use the appliance, the government would need to acquire a forged certificate from any one of more than 100 trusted Certificate Authorities.


The attack is a classic man-in-the-middle attack, where Alice thinks she is talking directly to Bob, but instead Mallory found a way to get in the middle and pass the messages back and forth without Alice or Bob knowing she was there.




Well this is lovely. Just lovely.

Running a Django Application on Windows Server 2012 with IIS

This is a first for me since under normal circumstances we run all our Django applications on Linux with Nginx, but we're in the process of developing an application for another department and due to the requirements around this project, we'll be handing the code off to them to deploy. They don't have any experience with Linux or web servers other than IIS, so I recently took up the challenge of figuring out how to run Django applications on Windows Server 2012 with IIS.

Based on the dated or complete lack of information around this I'm assuming it's not something that's very common in the wild, so I thought I'd share what I came up with in case others need to do this.

Fixing DPI Scaling Issues in Skype for Business on Windows 10

My setup for my day job these days is a Surface Pro 4 and either an LG 34UC87M-B or a Dell P2715Q monitor, depending on where I'm working. This is a fantastic setup, but some applications have trouble dealing with the high pixel density and don't scale appropriately.
One case in point is Skype for Business. For some reason it scales correctly as I move between the Surface screen and the external monitor when I use the Dell, but on the LG monitor Skype is either massive on the external monitor, or tiny on the Surface screen.
After a big of digging around I came across a solution that worked for me, which is to change a setting in Skype's manifest file (who knew there was one?). On my machine the file is here: C:\Program Files\Microsoft Office\Office16\LYNC.EXE.MANIFEST
And the setting in question is this:
<dpiAware>True/PM</dpiAware>
Which I changed to this: <dpiAware>False/PM</dpiAware>
Note that you'll probably have to edit the file as administr…

Installing and Configuring NextPVR as a Replacement for Windows Media Center

If you follow me on Google+ you'll know I had a recent rant about Windows Media Center, which after running fine for about a year suddenly decided as of January 29 it was done downloading the program guide and by extension was therefore done recording any TV shows.

I'll spare you more ranting and simply say that none of the suggestions I got (which I appreciate!) worked, and rather than spending more time figuring out why, I decided to try something different.

NextPVR is an awesome free (as in beer, not as in freedom unfortunately ...) PVR application for Windows that with a little bit of tweaking handily replaced Windows Media Center. It can even download guide data, which is apparently something WMC no longer feels like doing.

Background I wound up going down this road in a rather circuitous way. My initial goal for the weekend project was to get Raspbmc running on one of my Raspberry Pis. The latest version of XBMC has PVR functionality so I was anxious to try that out as a …
