v3.0

I updated "ubuntuprivacy.sh" to comment out wiping of OpenOffice history and include wiping of LibreOffice history.

#"ubuntuprivacy" written by commandrine.
#Please send comments and queries to commandrine[at]gmail[dot]com.
#Version 3.0 dated 22th July 2011.
#Pre-requisite is having "secure-delete" installed. Install it using "sudo apt-get install secure-delete".
#Save this script to your home folder. Run "sudo chmod +x ubuntuprivacy.sh" to make it executable.

The wiping of Flash cookies (which I blogged about previously) is also appended into this version.

Ubuntu update error

When I ran "sudo-apt update" command in Terminal, I get the following error.

commandrine@bridge:~$ sudo apt-get update

E: Some index files failed to download, they have been ignored, or old ones used instead.

Turning to the Ubuntu Forum, I get advise on running the following commands to rectify the missing keys issue.

gpg --keyserver keyserver.ubuntu.com --recv 3AD52A40B98E84D3

gpg --export --armor 3AD52A40B98E84D3 | sudo apt-key add -

gpg --keyserver keyserver.ubuntu.com --recv 9BDB3D89CE49EC21

gpg --export --armor 9BDB3D89CE49EC21 | sudo apt-key add -

gpg --keyserver keyserver.ubuntu.com --recv A6DCF7707EBC211F

gpg --export --armor A6DCF7707EBC211F | sudo apt-key add -

I encountered 2 keys that still generate update errors. Heading back to the Forum, I get the following steps to rectify the issue.

sudo -i

apt-get clean

cd /var/lib/apt

mv lists lists.old

mkdir -p lists/partial

apt-get clean

apt-get update

Problem solved.

“aspydrv.asp;.jpg”

Was reading this article about an alleged Anonymous hacker uploading a file “aspydrv.asp;.jpg” onto servers to compromise them.
This piqued my interest. I Googled the above file and found numerous sites hosting this file. Further research educated me that using the ";.jpg" at the end of the ASP file can fool insecure IIS servers.
Accessing one of the vulnerable sites, I try uploading a test ASP page written by my buddy, Simon, and the file successfully bypasses the file type check. I click on the uploaded ASP page and the "Hello World" message is published on my browser.
It is a simple trick to gain control of a vulnerable webserver but timely patching and hardening will thwart this threat.

"Firestarter: Starter for your Firewall"

My new article is out this month in Hakin9 magazine. It is for paid subscribers only and here is an excerpt of it.
"The firewall is the first line of defense on the network perimeter and end points. Firewalls are susceptible to targeted attacks (eg. social engineering, application vulnerabilities) but they are still the foundation upon which access control is built upon."
