Backtrack 4: Information Gathering: Dradis – Effective Information Sharing

One of the biggest problems when conducting penetration tests and vulnerability assessments is the organization of all the information obtained on the test. I used to use a program called Leo to organize my information because it had a tree like interface and you well able to create a well mapped out report of all your information. A new tool was released last year which has expanded on this same method and added some other very cool features. Dradis is an open source framework to enable effective information sharing during penetration testing exercises. It provides a centralized repository of information to keep track of what has been done so far, and what is still ahead. Dradis is thus an ideal tool to help in the process of security assesments.

After some research I located a repository from Stanford’s Center for Computer Research in Music and Acoustics called Planet CCRMA which is pronounced karma. Below I describe how to install the CCRMA repo on CentOS Linux so you can use yum to install various audio RPM’s.

Yahoo Small Business Web Hosting: Critical Error When Connecting To FTP Using FileZilla

Yesterday a friend contacted me about moving his site for Yahoo Small Business Web Hosting to another location. This typically can be challenging, regardless of web host, because of having to deal with someone else who has set this up and more than likely is not doing what they are supposed to be doing which is why the person wants to move the site in the first place. I was provided the Yahoo login information to the web and honestly had no idea how Yahoo Small Business has FTP set up. After logging in and searching around a bit I found the information I thought I needed and attempted to create an FTP user to login. After creating the FTP user I attempted to use the Yahoo FTP credentials in FileZilla to login but I continued to receive a “Critical Error” from the Yahoo FTP server. Below I describe the FTP error returned by Yahoo along with how I was able to work around the error.

The AC Power Adapter Type Cannot Be Determined, Please Connect A Dell 90W AC Adapter

Last night I upgraded the BIOS on my Dell Studio XPS 13 from A11 to A14. The BIOS upgrade appeared to work without issue however when the computer rebooted with the new BIOS version I received a boot error and then once I skipped the error I received a popup message within Windows 7 as well. The problem ended up being something really silly which is explained below but I wanted to note in case someone else ran into the same issue.
