Recently, Truecrypt webpage (www.truecrypt.org) was shown to be compromised. It comes along with a version 7.2 of Truecrypt that looks suspicious. Do NOT download any Truecrypt software from that website from the website from now and DO NOT switch to Bitlocker before a confirmation of what is going on has been thoroughly investigated.
If you are using version 7.1a and older of Truecrypt, you are most likely to be fine for now.
I will see what I can do to provide people following my blog or those who are interested with a replacement.
If you have further doubts of Truecrypt, please migrate to LUKS (https://code.google.com/p/cryptsetup).
Remember, DO NOT TRANSFER FILES UNENCRYPTED ! Even a Truecrypt container (version 7.1a and older) used to move secrets is much better than nothing.
