To avoid any confusion it should be clear that these are the developers of btcd not bitcoin core.
As far as I know the only bitcoin core developer working on an altcoin is gavin andresen.
I'm thinking that's probably a violation of federal law and like most of the us legal system they are entirely reliant on prosecutorial discretion to avoid prison time.
I would assume the files are encrypted with a symmetric cipher like AES.
Known plaintext attacks are not very effective against symmetric ciphers.
Indeed they're designed to be resilient to chosen plaintext attacks.
This is WRONG.
Almost all 802.11 a/b/g/n devices will actively probe for ESSIDs that they have previously used.
Your phone is constantly broadcasting for access points.
I really dislike the service (which I won't mention) that automatically hits all the various registries to gather this historical WHOIS information, but I won't deny it has a purpose here.
More likely they registered that domain for brand protection and repurposed it to keep their services up while they regain control of the.com. It's easier to register a domain than go through the UDRP with ICANN and/or the applicable registry to take it down when someone starts using it maliciously.
