dnsenum Returning Odd Characters After Installing Options Perl Modules On Backtrack 5

While working on an upcoming article for QD I ran into an issue with the Perl script. I followed the process of installing the optional Perl modules and when I went back to test dnsenum it would no longer return any IP addresses. Instead of dnsenum returning actual IP addresses it was returning odd characters. It turns out there is some form of conflict between and the Net::DNS Perl module. Below I describe the dnsenum issue in more detail and provide a work around by manually downgrading the Net::DNS Perl module by hand.

My Backup Pro For Google Nexus 7 Won’t Accept Email & Password

I downloaded My Backup Pro to use as a secondary backup on my Google Nexus 7 device which is running Android 4.2. When attempting to configure the the email address and password associated to the My Backup Pro account it continued to reject the information I was providing. Initially I thought the password must be too long, which it was, but even after shortening it to the allowed fifteen characters it continued to reject my settings. It ended up being the email address I used not being accepted because it included a “-“. Below I describe a bit more and provide a screenshot of the screen in question.

Calculate Disk Space Size Needed To Generate A Wordlist For Password Cracking

Today I was having a discussion regarding wordlist size, the calculation to come up with the specific size the wordlist would be once generated, and various other items revolving around password cracking. Somehow the application crunch came up which in the past has been used to generate wordlists however its fairly slow compared to other technologies out there specifically Hashcat/oclHashcat’s Anyhow during the discussion I was doing some searching and had not used crunch in quite a long time but was pleasantly surprised by one of the features which generates a quick, accurate, and useful output of information regarding number of combinations that will be generated from the combinations length plus the character set/wordlists input and how much disk space those the list will take up on the hard drive. Anyhow a couple interesting things I realized tonight using crunch that I wanted to share.

Hashcat: Use the Hashcat-gui On Windows To Brute Force MD5 Hashes

Hashcat is an excellent tool to use or security audits of passwords. I will be doing a series of articles relating to anything from simple brute forcing such as the article to more complex techniques using Hashcat, oclHashcat, and the Hashcat-gui on both Windows and Linux operating systems. The goal is to make people more aware of the technologies available to crack passwords which should allow people to audit their companies passwords for more strict enforcement. This article relates to using the Hashcat-gui on Windows 7 to crack 10 MD5 hashes and assumes that you already have successfully installed Hashcat and the Hashcat-gui.

Safari Shortcuts For The Safari Web Browser On Windows Operating System

There are many references to Safari shortcuts for OSX on Apple computers but not as many for Safari shortcuts on Windows computers so I figured it may help some people to have a reference for Safari shortcuts on computers running Windows. The below shortcuts have been specifically tested on Windows 7 Ultimate 64-bit and Windows XP Professional 32-bit  but I assume the below Safari web browser shortcuts will work on any version of Windows including all variations of Windows Vista, Windows XP, and Windows 7. Many of the Safari shortcuts for Apple are identical to the Safari shortcuts for Windows below. There are however many Safari shortcuts that are different because of keys being named differently on Apple keyboards versus Windows keyboards.
