Hashcat best64 Rule Details: Updated After The Best64 Challenge

Security1 Comment

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.

Remove GPS Data From iPhone Images On Mac OSX

SecurityLeave a comment

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.

View iPhone Image Location Data With Preview On Mac OSX

SecurityLeave a comment

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.

View iPhone Image Location Data With Photoshop CS5

SecurityLeave a comment

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.

Using RAID On Z68 Motherboard: Asus Z68 Extreme4 Gen3

InsightsLeave a comment

I recently got a new desktop computer that has a Asus Z68 Extreme4 Gen3 motherboard in it and wanted to configure RAID 0 on a couple terabyte hard drives to provide better performance and more space to my primary volume. Initially I didn’t see how to configure the RAID as I am used to an external hardware RAID card that has its own BIOS. After a little bit of poking I was able to locate the setting to enable RAID and then configuring it was fairly standard. Below I describe the setting to enable RAID on the Z69 Extreme4 Gen3 mobo and how to configure a new RAID 0 volume once RAID is enabled.
