Subject: On PGP (was: Wiretap or Magic Lantern?)

Whether it is cracked or not is moot. Magic Lantern was a keystroke logger. 

Presumably even if you are a pgp fanatic you will type the password in
somewhere and if the agent feeds back to a central database at that point
then pgp is useless to you. In addition to that, the keys (private key
included) are stored on a local system with a specific file extension. The
RPC DCOM vuln (along with hundreds of others from many different
architectures) existed for years without anyone knowing publicly. Anyone who
thinks that someone didn't know about it for at least some of that time is
naive. Likewise there are probably ones of a similar nature that are not
known of or patched yet.

By the way my last mail made it sound like I don't care if someone looks at
my mail. That isn't true. I do understand the implications and reasonable
concern is warranted. The intention of the message was to stress that it is
possible not to draw a conclusion on whether or not it would be justifiable.


I just realize that there is little I can do about it so I live with the
knowledge that anything I do on a computer connected to the net anywhere is
likely to be public eventually. And obfuscating it with fake email accounts,
proxies or usernames only slows people who really want the information. It
probably doesn't slow them that much.

Like I said before I hope any real NSA (or CIA or FBI) guys reading this
thread get a kick out of where and how we are wrong.

When you send a message (or browse a website or even send a ping with data
content) of any type on the internet it is the same as ordering a bag of
nuts at your favorite sporting event. All the people near you will know you
ordered it and how much you paid. I just choose not to pass my credit card
down the line to the guy with the nuts.

Although it is interesting to read, I wouldn't call an article in PCWORLD
conclusive proof that PGP hasn't been compromised by the NSA.

  It is a good article though :-)
