There is nothing new to me there.
In that first link you show that the FBI was trying to get access to BitLocker, but unsuccessfully. No surprise there. Usually the engineers on these products are not the kind of people who would want backdoors in their products, so this is totally unsurprising. It’s only, though, evidence that the FBI tried and failed once, not that they have succeeded or continued to fail.
The next three links (I discount IB Times because they are a linkbait rag), yes, this again is stuff I already know and people, again, are throwing out the actual explanation because it’s the “official explanation” just because it is that. What’s been going on here is that the SV companies were decrypting data upon getting various levels of notices from the NSA and FBI, whether these are a request, an NSL, a FISA request or a real warrant. This stuff actually happens quite often in lots of criminal investigations. Is this good? Probably not. We know that there is an overreaching of the NSA and FBI lately and this has to get more exposure, and the people who’ve made criminal acts should be brought to justice.
I’m also aware of lavabit and the NSA using NSLs to get information in an overreaching and often out-of-scope (legally speaking) information, but again they only used them to get information. They didn’t use them to bully people into modifying information or code. Doing so, especially to people who are already against them just damages the NSA more, just like in the lavabit case. They exposed how the NSLs were being used and shut down a business and source of income to do so. I know if I were the author of TrueCrypt and the NSA tried to bully me, I’d fucking relish in exposing them.
Finally, the TrueCrypt website says that they terminated support after the termination of support for Windows XP. It is not a far leap to say they aren’t supporting it now because XP is unsupported, which was the last major OS in consumer hands that doesn’t support FDE.
To quoth their website:
WARNING: Using TrueCrypt is not secure as it may contain unfixed security issues
This page exists only to help migrate existing data encrypted by TrueCrypt.
The development of TrueCrypt was ended in 5/2014 after Microsoft terminated support of Windows XP.
Okay, sure it’s a cigarillo, but that’s damn close enough to a cigar and not a white elephant.
