How Hard is it to Get Your SSL Cert Right?January 3

Guess what, this isn't a post about the recent Rogue CA presentation... just something I came across that frustrated me.

I recently went to check out adsense to see if it's ever actually made me any money. Being Canadian and using google.ca hourly (since google.com forces me to google.ca I might as well type it myself), I typed in www.google.ca/adsense. I was kicked over to https://www.google.ca/adsense and had the following appear in Firefox

I know it's obvious what the problem is, but let's look at my other screenshots since I took the time to take them.

Playing with Python - nmap XML port frequencyDecember 16 2008

Two Python libraries have caught my attention lately, the first is lxml and the second is matplotlib. Ideally I wanted to write something short, just to get a feel for the basics of them. The goal was figuring out what I could do quickly so that I could play around with arguments and output, yet still have an actual result. I also wanted a nicely formatted useful XML file to parse. I ended up going with nmap's XML output. I also decided that I would plot the frequency of ports in the file.

Is this useful... perhaps? I could see a sys admin wanting a count of specific open ports on the network or a pen tester wanting to know the most common ports on a target network.

The python script is extremely basic and is called via nmap_port_frequency.py <XML Input> <png Output>. The result is an image similar to this:

The above image is the output from scanning three hosts.

New Wordpress ThemeDecember 15 2008

The old site layout worked well for the last 2+ years, however I decided I needed something new. Certain lines were being cut off and I wanted to utilize page layout a little more.

Here's the result... using the iNove theme.

The Power of hexdumpDecember 15 2008

One of my favourite new commands has become hexdump. From time to time I go through my nepenthes hexdump folder to take a look at what I've recently seen.

These hexdumps on their own are fairly useless:

However, when you make use of hexdump it becomes much more readable.
