Wireless HotSpot using your laptop (Windows 7 and Windows 8)

I get to travel around and I have stayed in a number of hotels. One of the most important things for me is Internet access during my stay. I have been to hotels (major hotel chains) where the WiFi signal is so weak in the room that sometimes you need stand by the open door in order to send an email. That is not very convenient, so I needed a quick solution in such cases. By creating a hotspot using your laptop's Wireless adapter, you can have a very strong signal anywhere in the room to access the Internet from any other devices you may have with you (e.g. mobile phone).

I am assuming that your laptop has both an Ethernet port and a Wireless adapter. Before you start check Windows Updates to make sure you have all the latest security updates and the latest drivers for your Ethernet card and the Wireless adapter (consider rebooting if needed).

Reverse IP Lookup under Windows

Yes, dig is an amazing Linux tool, and yes, you can do reverse lookups by typing:
dig -x [IP Address]

However, if you need similar functionality under Windows, you can do:
nslookup [URL]

or for reverse lookups:

nslookup -type=PTR [IP Address]

ALL YOUR PICTURES "ARE" BELONGS TO US

Back in 2003, on a rainy night, an idea came to mind regarding the extraction of all the pictures from a host; ..and the title was inspired by the famous .."all your base are belong to us". [1]

I was looking at the thumbnail view of one of my folders and started wondering how does MS Windows® OS store information about thumbnails within each folder. Obviously that was the "thumbs.db" file which it was introduced with the release of W2K. (Note: Actually Win98 had the functionality of displaying thumbnails but you had to know the trick to enable this feature. In Windows Millennium the functionality was included but there was no thumb.db file).

One blog to rule them all..

After all these years of researching and posting in various blogs, forums etc, I decided to create a centralized repository for posting ideas, projects, solutions, suggestions and sometimes discussions about the latest issues around Information Security and Computer (anti)forensics. Bare in mind that anything posted in this blog is product of my own work and/or research, except it is stated otherwise, in which you will find all the relevant references. If you think I have missed a reference, please, do let me know.

Finally, any opinions expressed in this blog are personal opinions. Any code, programs and/or ideas found on this blog are given out as proof-of-concept and not for malicious usage. The purpose of the blog is to further understand and discuss Information Security, CyberSecurity, CyberDefense and Computer (anti)Forensics by looking into the strengths and/or weaknesses from different angles, through discussions and/or coding examples.

Hope you will have a fun ride..
