I upgraded "Firefox" to v8 and realised that it was sluggish due to configs being wiped by v3.0 of my "ubuntuprivacy" script. I modified the script as follows.

"HTTPS Everywhere"
Finished this column months ahead of schedule and it was finally published in this month's issue of "Hakin9".
An excerpt of it below.
"HTTPS Everywhere is a Firefox extension that was developed and is maintained by the Electronic Frontier Foundation (EFF). It was first released in June 2010 and is not available from Mozilla but can be downloaded from EFF’s site (https://www.eff.org/files/https-everywhere-latest.xpi)."
I should really get started on my next column draft.

"Prey: From Praying to Preying"
My new column is out in Hakin9 magazine. It was 2 months overdue so it is a relief that it is finally published.
An excerpt of it in the "Tool Time" column this month.
"Since the issue 7/2010 article Prey: A new hope, there have been developments in the device tracking tool. It has been enhanced to now be able to monitor lost Android smartphones and tablets when activated. There was a reported case in May 2011 where a Californian harnessed evidence collected from a similar tool, Hidden, to recover his stolen Macbook."

nessusjob
Was lazy to memorise the Nessus commands to start/stop the service as well as update its plugins so I decided to dump them into the following script.
#!/bin/sh
echo "\033[0;34mPrepping Nessus for scanning.\033[0m"
sudo /etc/init.d/nessusd stop
echo "\033[0;31mUpdating Nessus plugins.\033[0m"

My first column
Hakin9 asked me to be a bimonthly contributor to their new column entitled "Tool Time" and here is an excerpt of it.
"Hispasec Sistemas has managed the service, VirusTotal, since 1st June 2004. The website (http://www.virustotal.com) offers the public access to multiple Antivirus (AV) engines hosted by them to provision online scanning of individual files to uncover malware by harnessing a combination of signature-based and heuristic detection."

v3.0
I updated "ubuntuprivacy.sh" to comment out wiping of OpenOffice history and include wiping of LibreOffice history.

“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.

Interesting research done on the fake AV industry and eye-popping statistics.
"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."

Android smarphone screen capture
I wanted to take screenshots of my Android smartphone screen for my new security article and was having a nightmare doing so. It took 3 hours of research and troubleshooting to finally achieve success.
I relied on detailed information from this article to setup the Android SDK on my Ubuntu laptop.
Watch out for my new security article in Hakin9 magazine.
