You're still secure if you use https. If neither your computer nor the host you're connecting to has been tampered with, then you're safe irrespective of what's happening between.

Yeah, because illegitimate / spoofed certificates will never happen...

I think we're well on our way to a point where certificates can be mostly trusted. Of course certs can be stolen, but I would bet that "spoofed" certificates will soon be an occurrence of the past.

I'm confused. Are these accidental vulnerabilities or deliberate backdoors? If deliberate, why is there speculation about who might have installed this "secret code"? Do they have version control? Is there a specific human attached to the relevant commits? Serious question.

And a good one. They were definitely deliberate, but the other details are not public.

If this wasn't an intentional backdoor it raises the question, what source control methods were being used and are they secure? Has Juniper been compromised on a larger scale?

The honeymoon is over. The Internet is now a hostile environment. We cannot assume good conduct from any party of reasonable size and should assume deception from anything that isn't fully open source and vocal about it. It sucks to assume the worst...

It would appear that the "party of reasonable size" here is China or Russia, not a corporation.

I don't really get why you specifically mention these two countries. It could be because your government is at war with them but that would be speculation.

The problem goes much deeper. It could be any "larger" corporation or government or other entity having enough manpower. It could even be parts of a corporation or government entity.

However which way you put it, a program of which you don't have access to the source cannot be trusted.

Can you please explain how you reached that conclusion? What made you exclude US and UK?

That has always been the case. It's always been the case that if your adversary is a well funded government you need very careful security.

We knew this from Echelon in the 1980s.

Then use a browser that rejects RC4 (like latest Chrome).

The private key is used to negotiate a session key, which is then used as the symmetric key for RC4 or whatever stream or block cipher you are using. Those session keys are ephemeral and per-session, so leaking them is only a problem for those sessions.

(Also, since it's a stream cipher, it can't use the same key ever again, else you can xor those ciphertexts to get 2 xored plaintexts, which are much easier to crack.)

I'm looking at Juniper's news page [1] and its Twitter feed [2]...it doesn't give me a lot of confidence that this security breach or even its (apparently inadequate) patch doesn't even a news item or a Tweet. [1] http://newsroom.juniper.net/ [2] https://twitter.com/JuniperNetworks/with_replies

Was discussed yesterday on this thread https://news.ycombinator.com/item?id=10754917 which points to the proactive announcement Juniper made

It's not the first time when HN stories are doubled with Wired articles. I had one blatantly replaced. This site has a preference for fear-mongering reporting... I mean Wired.

With certificate transparency, at least we'll know about it - afterwards, at least.

It's sad but events like this one make me turn away from Internet. I started using Signal because I don't want people seeing the messages I post. But in the end it's only trust that makes me think Signal is safe to use. A lot of people also trusted Juniper. But that trust is gone. And not only for Juniper. What about other brands? We don't know.

You're still secure if you use https. If neither your computer nor the host you're connecting to has been tampered with, then you're safe irrespective of what's happening between.

I get where you're coming from and I want to agree with you but...

While that used to be true, based upon recent history we, unfortunately, can't blindly trust HTTPS to always be "secure" 100% of the time anymore -- whether due to things like Heartbleed, fake certs signed by a root CA, protocol attacks, or some other vulnerability that hasn't even been discovered yet.
