Well I just started my Master’s degree program with the University of Phoenix! While I do love the online structure and tools available, I quickly noticed that I found myself logging in repeatedly throughout the day to see if there were new posts. Many times there are no new posts, so it gets frustrating after doing this repeatedly day after day. I searched high and low within the site to see if there was so [Continue Reading]

The exploit involves a specific URL format that will redirect the victim to a site/file of the malicious user’s choosing.

Had some interest in the Lookout keylogger application recently, so thought it would be a good time to provide an updated release. This one does a more thorough exception handling job, as well as provides an option to enable or disable error messages (to stay in stealth mode). Adds itself to the Startup folder so [...]
Tonight I finished putting together a GUI front-end for a font tool my buddy is using. This free tool, ttfpatch (http://www.derwok.de/downloads/ttfpatch/), originally coded by Wolfram Eßer is a command-line tool for editing True Type Font attributes.

So I set to wor [Continue Reading]
