I recently installed Oracle on a Windows 7 computer to test some tools that are available in Backtrack. I am very new to Oracle so it has been a bit of a learning process including the fact that I had no idea you can install Oracle without having to pay any money to download it so I also plan on writing an article on how to do this. Anyhow after the initial Oracle install we were testing oscanner from Backtrack and locked all of the Oracle accounts which was a bummer because I wasn’t sure there was a way to correct the issue. Turns out it is really easy to unlock the Oracle accounts if you have access to the Oracle server so below I describe how to unlock Oracle accounts when it appears they have all been locked.
Earlier today while working with a friend at our offices we were playing around with a large NMAP scan of the anoNet network. His computer would not open the network topology in Zenmap because of a lack of RAM so we were looking at it on another laptop with much more RAM. After discussing it for a little bit we were curious how many hosts had been discovered on anoNet but initially I didn’t see an easy way to get this information. Use the information below for a quick count of hosts in Zenmap discovered via a NMAP scan.
Earlier today a client called and said he had a virus or some spyware on his computer that could not be removed. The client was remote so I had to login to his computer to investigate. I used the typical tools such as Malwarebytes and Microsoft Security Essentials but the issue still existed. It seemed as if the computer had a proxy server configured but the proxy did not show underneath Internet Explorer connection settings or any of the other browsers. It didn’t happen all of the time but every now and then a pop up window would appear for the site GimmieAnswers.org and some other pop ups regarding “Daily Giveaway Contests” were also displaying. Below is more information on how the issue was resolved.
