WPA Cracking
An interestingreference on Schneier’s blog to an article describing a “in the cloud” service to crack WPA keys.It is the realisationofthe concept of distributed security cracking mentioned in 2008 by Chad Perrin, not sure if he was the first to introduce that idea.

Weekly Digest #1 – Interesting Articles

#4 - Posted on 23 July 2010 - Author: SM - Category: Security

Working in IT Security I receive and get to read lot of security related articles. I will list here a summary of the ones I found the most interesting, the idea is to try publishing this list on a weekly basis… not sure I will always have the time to do so, hence why the subject of those posts will be numbered, and we start with week #1:

– Safari Vulnerability
An Auto-fill vulnerability in the Safari browser which allows attackers to get info from your personal contact details.
Reading the comments on that article, it is not clear if this could also affect other WebKit based browsers such as Chrome.
It may be best practise anyway to disable the auto fill option in any browsers you are using.

New Version of Truecrypt

#3 - Posted on 21 July 2010 - Author: SM - Category: Cryptography

Truecrypt is a tool I have been using for a while, it is a great product and… free!

It allows for full disk encryption, being your desktop hardisk or a USB stick.

A new version has just been released, version 7, and it now provides:
– Hardware acceleration
– Auto-mount (windows)
– Security improvements related to windows hibernation files

Its main features are:
– Creates a virtual encrypted disk within a file and mounts it as a real disk.
– Encrypts an entire partition or storage device such as USB flash drive or hard drive.
– Encrypts a partition or drive where Windows is installed (pre-boot authentication).
– Encryption is automatic, real-time (on-the-fly) and transparent.
– Parallelization and pipelining allow data to be read and written as fast as if the drive was not encrypted.
– Encryption can be hardware-accelerated on modern processors.
– Pro...

Email working again

#2 - Posted on 4 June 2010 - Author: SM - Category: Misc

This morning I checked my spam folder related to this website/domain name and noticed there had been no new spam for about a week… not that I am missing it but this did not sound quite right!

Indeed, it looks like my service provider recently had some issues with one of their site being compromised and used to host some malicious software and as a result their back-end domain was blacklisted by Google. Something they did not like too much…

They took the drastic decision to change their back-end domain, it seems to have worked. But in the process they have messed up some accounts. They have now fixed the issue with my domain but if you have sent me an email recently then, I am afraid, that email is lost and you probably did not receive any error message either!

I never thought spamming could be useful to the receiver of it, but in this case the lack of noise highlighted another issue :)

It was only yesterday…

For over 3 years this website has not been updated and it was time to give it a face lift!

It is actually quite astonishing to think this website has existed since 1998, 12 years! I guess I am getting older, my hair are getting greyer and there is less of it! One thing that hasn’t change though is my interest in Cryptography.

Because of a busy professional life in the IT Security world I haven’t been able to work on the BUGS algorithm for many years. However, I have recently completed a Master in Information Security at the London Royal Holloway University. I logically chose to work on a cryptography subject for my Master Thesis. This allowed me to spend some time back on the BUGS algorithm and, for the first time, learn some cryptanalysis techniques!

The main subject of my thesis was to give an “Overview of Modern Symmetric-Key Cipher Cryptanalysis Techniques”, as such after a general introduction on cryptography and cryptanalysis I focuse...
