No, I'm saying don't scream "CHANGE YOUR PASSWORD EVERYWHERE" without 
basis in fact. I'm saying stop speculating on what they neither know nor 
understand while coming across as authoritative as to appropriate actions.

What the technical guy said was well done. Specific areas upon 
identification of specific concerns. Not "CHANGE ALL PASSWORDS!", change 
<this one>, if you accessed during <these hours>, maybe, just in case. 
With certainty ONLY if you receive a letter from Revenue Canada. 
Specific threat identified, mitigated easily and quickly. Not 
everything, everywhere, just in case.

Heartbleed didn't reveal anything, it allowed encryption to be bypassed, 
maybe, in very specific and uncommon ways, and MAYBE there was something 
useful in there, and MAYBE somebody did something with it. Somebody had 
to utilize it, do further unreasonable and nefarious things, then 
attempt to mine it in nefarious ways.

Never mind that zeroing memory or sending true gibberish would have 
avoided it all. Never mind that properly isolated systems wouldn't let 
you get to really useful stuff. Never mind that there shouldn't have 
been anything useful in memory to send back in the first place. (Poor 
programming practices, that surprisingly didn't get revealed via code 
review. Hopefully there's some consternation in that community on all this.)

Use to be media, journalism, required a factual basis for reports. Now 
they're making it up on the fly. (OK, never mind the 'now' in that.) 
Equally irresponsible is whichever authority told them that's the right 
thing to do.

Absolutely. If that's as far as they went. But they went further - the 
sky is falling, and change your passwords everywhere. Even though, as 
pointed out elsewhere, all you'd be doing at the time is telling them 
your new password, and you'd have to do the same again in a few days.

Sandvine - that's it, thanks. Didn't know about Blue Coat.
