We're seeing the same thing happen to a couple of developers active in
the censorship circumvention problem space as well (though it's not
for the first time it's happened).

 Besides, why would an intelligence agency want your bitcoin when
 they can just intercept ASIC miners and make their own?

Perhaps they have other motives for attempting a cybil attack against
developers than trying to acquire Bitcoins.  Say, by making it easier
to subtitute alternate versions which are instrumented to make the
users easier to spy upon and later take down?

 If you're using PGP to verify Bitcoin downloads, it's very important that
 you check you are using the right key. Someone seems to be creating fake
 PGP keys that are used to sign popular pieces of crypto software, probably
 to make a MITM attack (e.g. from an intelligence agency) seem more
 legitimate.

I find it more likely that fake PGP keys are from corporate industrial 
espionage and/or organized crime outfits. Intelligence agencies will stick
to compromised X509, network cards, and binary code blobs.

 I think the Mac DMG's of Core are signed for Gatekeeper, but do we codesign
 the Windows binaries? If not it'd be a good idea, if only because AV
 scanners learn key reputations to reduce false positives. Of course this is
 not a panacea, and Linux unfortunately does not support X.509 code signing,
 but having extra signing can't really hurt.

Uhhmm, real operating system use package managers with PGP instead of pre-
compromised X.509 nonsense. https://wiki.debian.org/SecureApt

Yes, the -setup.exe installers are Authenticode (or whatever Microsoft is
calling that these days) code-signed.

Note that Bitcoin source and binary downloads are protected by both the
PGP WoT and the certificate authority PKI system. The binaries are
hosted on bitcoin.org, which is https and protected by a the PKI system,
and the source code is hosted on github, again, https protected. A MITM
attack would need to compromise the PKI system as well, at least
provided users aren't fooled into downloading over http.

From the user's perspective: In the beginning I found it difficult to
find the keys. At last I have made this side for documentation:

https://www.olivere.de/blog/archives/2013/06/02/install_bitcoin_client/

Okay, is outdated meanwhile ...

Normally people fetch the keys by key-id from a well known key server.
Not because they are paranoid, but because it is the most convenient
method under Linux.

A Google search for Gavin+Andresen+gpg brings me herein:

http://sourceforge.net/p/bitcoin/mailman/message/30551147/

Key-Id?

Nevertheless, I'm glad that you guys signed anything. That makes me
sleep better. I really check this.
