Recently our friends working on the Hashcat projects had a open community challenge called The Best64 Challenge or TB64C. The reason being the fact that TB64C was to improve the most widely used ruleset that comes with all of the Hashcat products including oclHashcat-plus, oclHashcat-lite, hashcat, and hascat-gui. There is nothing better than when projects such as Hashcat get the community involved and what better way to do so than to provide a contest for people to provide feedback in the for of personal experience. Anyhow awhile back I wrote an article on tools.question-defense.com that described each of the best64 rules in more detail and there was a request for the article to be updated now that the ruleset has been improved. Below are the details of the new best64.rule file that will be released in all new releases of the Hashcat software line as of 04-21-2012.
The past couple of days I have written a couple articles about how to view iPhone image GPS data on a Mac using Photoshop and Preview. Each of these articles included a mini warning at the bottom of the article noting that you should keep the GPS data in mind when uploading images to social media sites, sharing the images, etc. so I figured I should write a quick article showing a method you could use to remove this GPS data before sharing the images either on social media sites, via email, etc. Below there are details of an easy way to remove GPS details from images on Mac OSX.
Yesterday I wrote an article on viewing iPhone image GPS data via Photoshop on the Mac but since not everyone has the need to have Photoshop along with the fact that Photoshop is not cheap I also wanted to show a way to view iPhone image GPS data without having to install any third party software on your Mac. You can easily view iPhone image GPS data using Preview which is installed by default on Mac OSX. Below I describe how to view iPhone image GPS data using the same example image from yesterday with Preview.
Yesterday I read an article on location data that is included with all images taken on your iPhone. This type of location data, which is also known as Geo Data or GPS Data, is included behind the scenes on all sorts of media that you create on a day to day basis so while I knew this and was familiar with the type of data that is included I had never spent much time looking into this data. Since I typically use Adobe Photoshop to edit images I figured I would start there and see how I can view location data for images taken on my iPhone within Photoshop CS5 which is the current version I am using.
The other day I had a wireless network packet capture file saved as a .cap file. The ESSID that was displaying via normal aircrack-ng output of the WPA/WPA2 wireless packet capture lead me to believe there was at least one space included in the beginning of the ESSID and likely after the ESSID since it was not processing properly using oclHashcat-plus. I had never run into this before so wasn’t exactly sure the easiest way to figure out the number of spaces so I posed the question in the Freenode aircrack-ng IRC channel and got a couple responses which are noted below as well as instructions following the clearest solution.
