We use a web application to manage much of our system security. Much like Windows, we use a role based security system (think user groups). When creating new user groups we often reference standard user group names. Some of these names are stored in a Word document. So, when a hyphen (i.e., short dash) is entered into Word followed by a dash, it is automatically converted into an "en dash". This is when the single dash is expanded and looks "wider" than normal.Since we run some scheduled tasks to regularly perform functions based on user group names this automatic formatting feature of Word becomes an issue. The script looks explicitly for the hyphen (ASCII decimal code 45/hexidecimal code 2D) but finds the en dash (ASCII decimal code 150/hexidecimal code 96). For reference,...

I needed to get my head around dynamically searching all fields in a given set of database tables for PCI Cardholder Data. I had previously come up with a rudimentary query to search for credit card numbers:http://learningpcs.blogspot.com/2009/03/credit-cards.htmlThis time, however, I wanted to try and handle it all via SQL. For starters, I needed to determine which fields I wanted to work with. My initial query (from the link above) was:SELECT SO.name, SC.nameFROM sysobjects AS SOJOIN syscolumns AS SCON SO.ID = SC.IDWHERE (SO.xtype = 'U') AND (SC.name LIKE '%_SUFFIX')I needed something more powerful.

It took me a while to find this link:http://social.technet.microsoft.com/Forums/en-US/windowsserver2008r2networking/thread/7d7adbb7-f0a3-4292-9417-4024081dd782Apparently you have to log onto the DNS server and look in the %SystemRoot%\System32\DNS\ directory; the file name I worked with was mydomain.myhost.com.dns where mydomain.myhost.com was the domain name of my environment. Basically, look for a file with the .dns extension. When I looked at the DNS server on our domain I realized it looked a lot like the regular hosts file found on client machines (%systemroot%\system32\drivers\etc\hosts), but, with significantly more entries.

Since I am slowly building up a Powershell Pen Testing suite, I wanted to grab a few fuzzing functions.

I reimaged my Windows 7 machine and want to make a new account strictly to contain pen testing tools. Wondering how I could do this the Powershell way I started looking around.

I am working to learn how to properly use custom code from within an ASP.NET project. I added an App_Code directory to an empty project. Within the App_Code directory I created a folder called DLL and a file called DLL.cs. Looking back, I would have done it differently. The path [ProjectName].App_Code.DLL is pre-pended to the file name, DLL, in this case. So, when I reference the object in my project, CachingTest, it is fully written as CachingTest.App_Code.DLL.DLL. The second DLL in the name makes it a little more confusing. What I would more likely do is name the .cs file after the Object I am working with instead of the Folder class.

now that it looks all but certain the Verizon iPhone will be announced tomorrow, one of the questions that arrises is will users switching from AT&T help take the load off and create a better level of service for everyone? First, a personal anecdote: I left Montreal to fly to CES 2011 last Tuesday. In Montreal the iPhone is fast, like HSPA 7.2 fast, with nary a dropped call and lost network signal, and a battery life that lasts as long as Apple’s TV commercial suggests. I switched planes in Charlotte and began to roam on AT&T. My iPhone 4 showed full bars but I kept getting a popup saying there was no network connection. That means the tower was broadcasting but there was no backhaul behind it. Like if your home Wi-Fi router is fine but your broadband ISP is down — lots...

I finished writing a driver for the Zephyr2 on the iPhone. It's the same multi-touch solution that Apple has used starting from the first generation iPod touch and up to and including the iPad. Now, of course this shouldn't be construed as a promise to support the iPad eventually, but this multi-touch driver is definitely a concrete milestone that is important for pretty much all of Apple's mobile Internet devices. More immediately, this is pretty much the sole remaining blocking issue on the first-gen iPod touch and one of the two major issues on the iPhone 3G. The other issue on the iPhone 3G is baseband SPI.
