How much longer can this continue? We have American agencies attacking
American companies "because terrorism". It's been 13 years since our trauma,
maybe now's the time to remove the razor blade from our wrists, look ourselves
in the mirror and just carry on. Bad stuff is always going to be in our future
— stuff that will increasingly appear preventable between the Internet and a
lot of hindsight — but our current solution is only making things worse. The
war on terror, like all the metaphorical wars, is really a civil war. It needs
to stop now.

I'm actually somewhat torn on this.

While I'm against _mass_ surveillance, I think that targeted surveillance can
be a good thing. By nature of it being targeted, it is expensive to use on
more people than necessary. The kind of spying the CIA would enable through
compromising Apple secrets would be restricted to high-value targets if for no
other reason than to ensure none of their targets knew they had that
capability.

There are bad people out there, and we expect our government to stop them.

Targeted surveillance... like a search warrant?

Somehow we have been doing fine under the constitution for 200 years. Now a
dozen men kamikaze a building, and we have to take away everyone's freedom in
order to protect them?

F that. Police and the executive branch are just being lazy. Get off your ass,
do some human intelligence, investigate leads, and get a warrant if you have
probable cause. Otherwise, get the hell out of my email.

When the chances of being killed by police are 55x higher than being killed by
a terrorist (or whatever the recent number was) and we want to give the State
more power, we are fools.

The USA has never needed a search warrant to conduct foreign intelligence. A
search warrant requirement is a 4th amendment protection afforded to US
citizens. Foreign intelligence does not require courts unless you're trying to
get foreign information from US companies (like the PRISM program and the FISA
courts).

The FBI (who is responsible for all intelligence conducted in the USA, against
foreigners or Americans) is absolutely required to get a search warrant.

The iPhone is one of the most popular phones in the world. Is it that crazy
that the CIA is interested in them for intelligence gathering purposes?

~~~
appleflaxen
I'm fine with the legality foreign intelligence (even if I'm not sure it's the
best policy). But what does that have to do with anything? The Snowden
disclosures show that they're doing far, far, more: essentially indiscriminant
eavesdropping of every possible form of domestic communication.

~~~
flyryan
My point is that you were arguing against targeted collection. Going after
individual devices is a scoped and precision form of intelligence collection.
You were saying that this type of intelligence isn't targeted and was instead
insisting they should have to get a warrant.

The point the original commentor was trying to make is that this type of work
is much more preferable to the mass collection that you're referring to from
the Snowden documents.

~~~
obvio171
I don't know if inserting backdoors on apps in the _development_ process,
before they go out to _everyone_ , counts as targeted collection.

Every time I read about a private company being targeted, I remember how
simply _state-level spies_ have been compromised. Hanssen[1], for instance,
betrayed the CIA over 22 years, for just $1.4M. The info leaked included info
on other agents, at least one who was executed.

Or [2], Walker gave crypto info to decrypt Navy messages. For a few grand a
month. There's plenty more listed even on Wikipedia. The amounts involved
seem... not that high.

Now, sure, Apple almost certainly has higher security. (Quote from the above
spy: "KMart has better security than the Navy.")

But with state level resources, do we think employees can be flipped? Or, why
is the NSA not getting to grads early on, helping their career, while having
them really be agents all along?

I'm on my phone and can't find the reference now, but there was a young
physicist that leaked into on atomic weapons purely because he felt the US
shouldn't have a monopoly on the capability. The chance that some bright,
highly-sought, employee feeling that the US _should_ have spy capabilities is
approximately 1.

Is every remotely sensitive employee routinely monitored? Their families? They
never get into " life threatening " scenarios? Or embarrassing scenarios that
they might feel is the end? (For some, that's as simple as getting a mistress
pregnant, and not being able to bear others knowing.)

Just seems like the human employees have got to be compromisable in one form
or another, given the resources of the NSA and CIA.

Real spies don't work for money; they work for/against an ideology. Money
would actually be a tip-off that they're a spy; if you have high level
security clearance, your bank accounts are monitored.

The NSA/CIA/FBI almost certainly do have moles working within the major tech
companies. As do the intelligence agencies of China, Russia, the UK, France,
Germany and Israel.

As many have noted, this does need to stop but it won't. And the problem lies
squarely with you and me.

Try this experiment: Ask a group of 5-10 people around you to raise their
hands if they've been pissed off at any branch or level of their government.
Then ask them to keep their hands up if they've contacted their
representatives about that issue. Finally, ask them if the method of contact
they used was the phone or written (not email) letter.

I'll bet dollars to donuts that not a single hand will be in the air.

You and I are the problem because we don't hold our representatives
accountable. We really only pay attention (and marginal attention at that)
during election time by buying into the campaign bullshit. At best we sign an
online petition but the politicians barely care about that. They know that its
easy even for the most apathetic to click a button. Sure, in cases like net
neutrality it can get their attention but I'll submit that what _really_ got
their attention was the number of phone calls they were getting.

Yes, _I_ specifically am to blame because _I_ haven't called or written my
representatives. That's going to stop. We need to be on the horn with these
people frequently. Weekly. When they're in town we need to be in their faces.
They said, "If you see something, say something." Well, I see corruption and
I'm going to point right at them and tell them. Will you join me?

EDIT: I should add that we need to be contacting them when we approve of the
work they're doing. They need data. Most of the feedback they receive is
negative (and for good reason) but without positive feedback they're left
searching and unfortunately the guys who claim to have the answers are the
lobbyists. But remember, there are around 15,000 lobbyists in Washington D.C.
but 131,144,000 voters voted in the 2012 Presidential election. I like our
chances, if only we get involved.

I wonder how many people are genuinely afraid of raising their own profile in

political action against the actions being discussed here.

I'm by no means an important person, but from what we've learned I don't even

I understand where you're coming from, and clearly it's an individual choice,
based on one's judgment of risk vs. reward. But let me add that when people
choose that position, it just makes it that much easier for these guys to keep
doing what they're doing, and getting away with it.

FWIW, I routinely criticize the CIA, NSA, etc. here, on Twitter, on Facebook,

_nothing bad has happened to me as a result_

How can you be certain? How many really successful job interviews have you had
since you started your one-person campaign, where the hiring company
inexplicably dropped you like a hot potato? Do you regularly check your credit
rating to see if weird stuff is showing up? Have your bicycle tires quit
holding pressure?

I ask the last question because East Germany's Stasi did that sort of thing
([https://books.google.com/books?id=GlbAmn_cajYC&pg=PA160&lpg=...](https://books.google.com/books?id=GlbAmn_cajYC&pg=PA160&lpg=PA160&dq=stasi+deflate+bicycle+tires&source=bl&ots=cejL_NmSWp&sig=zUmIgpsXkx4TFn0fJK

The USA "national security" establishment/"intelligence community" gets
unbelievable amounts of money, that they _must_ spend. Why not make and use
"smell chairs" or randomly screw with people that openly oppose the deep

Well, that's a fair point, so maybe I should say "nothing overt and noticeable
has happened as a result." Beyond that, I could speculate about really subtle
stuff, but that strikes me as a sure road to a level of paranoia that I don't
want to engage in.

bediger4000
What level of paranoia is too paranoid, and why?

Three years ago, almost everyone laughed at folks who claimed the NSA was
watching everyone. Now, it's an article of faith, and there's some evidence
that people have changed behavior because of that faith.

Any sufficiently advanced level of precaution is indistinguishable from
paranoia. That East German activist was probably a little puzzled by flat
bicycle tires, but probably shrugged it off. What are we all shrugging off
today? Stock market weirdness? Oh, that's just HFT, right?

It's known that folks profited off of "top secret" CIA-led coups in the 1950s
([http://tuvalu.santafe.edu/~snaidu/papers/coups.pdf](http://tuvalu.santafe.edu/~snaidu/papers/coups.pdf)),
so it's not out of the realm of reason to look at the stock market today to
see if the current "intelligence community" is profiting.

~~~
mindcrime
_What level of paranoia is too paranoid, and why?_

That's a good question. Why are you asking? Who do you work for? What are you
going to do with this information?!??

Just kidding... it _is_ a good question, and I don't have a perfect answer. I
guess I'd say the level of paranoia is too much when you reach the point of
diminishing returns... that is, when it turns out that, even if you're right,
knowing that doesn't help you because there's nothing you can do about it.

So, maybe an NSA agent sneaks into my parking lot every night and lets a few
pounds of air out of my right rear tire. I can't prove that doesn't happen.
But what am I going to do, camp out in my truck all night with my pistol at
hand, hoping to catch the guy in the act? Not practical. Hire a private
security guard? Not practical either. Etc., etc.

What strikes me after this revelation is how unique the United States is,
because:

(a) it has dozens of companies that create technology the rest of the world
uses, and (b) it has a govt. that secretly works to undermine the technology
developed by those companies.

You're not going to hear about many foreign govt's actively hacking their
country's software products, simply because they could easily/secretly
armtwist cos. into installing backdoors at the beginning. Take China for
instance - do we think it needs to hack into, say, Huawei phones or Wechat? I
don't think so.

As a foreigner, that is why this "fight" between US software cos. and its
govt. is so fascinating. It's made possible through a unique combination of
capital, freedom and history. And I hope it remains that way, for the sake of
the rest of the world too.

~~~
flyryan
Your example isn't a particular good one. Huawei has been accused of
backdooring their products for the Chinese government on numerous occasions,
including presentations at DEFCON exposing those backdoors. There are also
numerous cases of backdoors in Chinese cell phones.

~~~
lawnchair_larry
But his point was that China's government doesn't attack the company to get
those.

How do we know how any putative arrangement of this type has come to be?

The implication of the article is that this is some sort of specific attack
against Apple. Surely the reality is that the CIA, and pretty much all
3-letter agencies globally, in a concerted and organised way try to break the
security of all secure devices. That's a big part of their job - you can't
gather intelligence if you can't read it.

The good things in the article are two-fold: firstly, Apple haven't just
capitulated and handed over whatever is asked of them, and secondly the
documents about the effort don't specifically mention any sort of success
which could be interpreted as the agency failing. Of course, if they had been
successful I imagine they'd keep as quiet as possible about it.

~~~
Intermernet
I think the point of The Intercept releasing this Apple specific info (mostly,
there's a bit about Microsoft being targeted as well) is to try to appeal to
the large number of Apple customers. I'd love to see some of the other line
items in the leaked CBJ document, as there are probably some other targeted
attacks documented.

Regarding Apple not capitulating, I'm giving them the benefit of the doubt,
and assuming that they're telling the truth, but wouldn't the NSL system mean
that Tim Cook couldn't reveal if Apple had been forced to release data?

I'm hoping that he has a personal warrant canary policy, and would just remain
silent if asked about something he can't talk about.

~~~
a3n
"No comment" from Cook would be an interesting standoff. If he were prosecuted
for it, that would confirm something NSL-like. But would it be worth it to a
CEO to go to jail for a few years for a principle?

~~~
Intermernet
That of course, depends on the strength of said CEO's principles.

This would be, of course, one of the hardest tests of professional principles
you could imagine a CEO going through. I personally think Mr Cook would be a
good candidate for passing this test, as he seems to have a track record for
standing up for what he believes in.

I also have a feeling that the US government would think twice before taking
on the Apple PR juggernaut head to head. It would be too closely matched for
comfort. Apple probably have greater mind-share than any of the political
parties.

As you say, it would be an interesting standoff!

~~~
jkestner
It's a little discomforting that we're hoping that corporations, presumably
guided by a profit motive, will defend us against the government formed for
the people (though more heavily influenced by other corporations). Even if
Apple is trustworthy for a company, I'm not going to enjoy the future in which
we pick our favorite companies to enact policy.

Now, this is obviously happening to Google, et al, as well, so a joint action
by the captains of industry — an appeal to the public more than the court —
will be more effective.

~~~
mindcrime
Nothing wrong with "profit motive". Remember:

 _It is not from the benevolence of the butcher, the brewer, or the baker that
we expect our dinner, but from their regard to their own interest. ~~ Adam
Smith_

That said, I'd personally like to see less power aggregated into the hands of
_both_ governments and big mega-corporations. But the big difference between
the two, to my mind, is that governments have a near monopoly on "legitimate"
use of force, and have lots of men with guns, tanks, bombers, nukes, etc. at
their disposal. Corporations mostly lack those things, except to the extent
that they collude with the governments.

~~~
jkestner
Yeah, I agree that profit motive is a motive I can work with. I guess
libertarianism can be appealing when the government acts like a tumor.

The government's monopoly on legitimate use of force is more relevant in less
developed countries. Here, you can do more damage more easily by attacking
computer-controlled infrastructure. (Imagine if the NRA was pointed at the
real threat? Maybe they'd look a little like Anonymous.)

Hah, yeah.

The first bit of the article is very big about compromising XCode, and I
couldn't help but think that Lockheed basically just got the .gov to pay them
to "rediscover" _Reflections on Trusting Trust_.

------
Asparagirl
If I'm understanding this right, this article is claiming that the CIA served
up [edit: _could_ serve up, not proven they did, see comments below about
plausibility] poisoned versions of XCode, which would then be used to make App
Store apps that eventually phoned home to Langley with either app-specific
data or whole-phone data.

This raises so many questions, among them:

1) What was [edit: would be] the criteria for serving up a poisoned version
instead of a real version of XCode to a dev? Was it [would it be] limited to
downloadable versions or were DVD software copies affected too? One
possibility came to mind: Does XCode come in different flavors based on county
of sale/download, language, or a combo of the two? If so, would that be that
criteria for their attempt to not target US citizens, by crudely targeting
non-US and/or non-English app developer accounts? Because that would be the
fakiest attempt yet at trying to claim plausible deniability, since so many
apps with mainly American userbases are developed by overseas devs.

2) If a dev had a poisoned version of XCode, how could they not see a
mysterious server being pinged during their development of the app? How could
Apple not see something amiss during their QA of the app before they pushed it
to the store?

3) If I were an evil genius Big Brother no holds barred government, I'd want
data from messaging apps, social networks, and geolocation apps most of all,
less so from things like single-player games. Thoughts on which apps are
likely to be in the top 5 of their wishlist?

4) Does this mean that PhoneGap / Cordova / non-native HTML5 apps really are
better? :-)

Say, why did Facebook change to a native app again?

~~~
mts_
Theoretically speaking, if you were building an PhoneGap/Cordova app binary
using a compromised seed of Xcode it would be no different than building a
non-PhoneGap/Cordova based iOS app.

So I'm not sure why you are referencing Facebook switching from a WebView-
based app to a more native approach.

In addition, if the Xcode installation was compromised nothing should be
considered safe on that device going forward.

~~~
Asparagirl
I was joking about the longstanding native app versus non-native app debate,
but thank you for the info. But perhaps if the crucial part of XCode that
"phoned home" was not the WebView component but some other component, might
that make a difference?

Of course this is all very hypothetical unless someone finds an example in the
wild.

------
okasaki
The cynic in me feels that this might be part of a PR campaign coordinated
between the US govt and US tech companies to try to give the impression of an
adversarial relationship between the two.

The article quotes Steven Bellovin: “Their attitude is basically amoral:
whatever works is OK.” If you forgot the article, could you tell who this is
talking about? The government or the corporations? It seems like it fits both
pretty well. The two entities both have a lot to gain from cooperating. Why
wouldn't they? Whatever works.

~~~
SagelyGuru
It is certainly in the interests of the government and its spying agencies for
the big monopolies to be successful. It must be a comforting thought to them
to know that if they bug just Apple and Microsoft, at a stroke they have over
90% of the population under effective surveillance.

~~~
higherpurpose
It's a shame Apple became so cooperative with the government recently. They
agreed to "share cyberthreat info" which could mean zero-days, and maybe much
more, which we know how the government will want to use _first_ (hint: not for
security).

My guess is Tim Cook agreed for the same reason Microsoft agreed to do the
same thing long ago, and now again with the new program - to get government
contracts, such as the one where Apple Pay will be used to get federal
services and with the plan to use Passbook or whatever as driver license in
the future. Apple actually announced this in the very same day they announced
it will share cyber info with the government, so it's not even trying to hide
it.

I doubt Steve Jobs would've compromised the same way. As we've seen from the
leaked Snowden charts, Apple only entered PRISM after Steve Jobs died.

As for Microsoft, I won't even waste my breath. They would sellout anyone for
an extra million dollars. They only fight against this stuff when it seems to
be publicly damaging them, because they don't want to lose billions of dollars
in revenue from abroad because of this issue. So they would have no problem
giving US authorities data from abroad, as long as it's still secret. Once it
gets public they will "fight hard" against the practice.

~~~
sseveran
I believe Microsoft was one of the few companies to challenge the NSA in the
early 2000s. If I recall correctly Ballmer thought that the NSLs would
eventually become public and Microsoft needed to be on the right side of
history by challenging them.

Seriously. This isn't even bad. Go to DEFCON and you'll see a ton of people
doing this crap. There is a reason a bunch of paranoid people (includes me)
bought faraday cages for our phones. Everyone is trying to break in to the
little black boxes we carry around with some of our most personal information.

They have _ACTUALLY_ done bad crap. This is normal security research. There is
no need to blow normal research and security work out of proportion. Xcode is
signed, they can't just modify it and let it go. The OS X updater is also
likely secure and maybe they just figured out how to trick their own computers
to install a keylogger. Good, but it probably doesn't work that well. And it's
fine! It's research!

Lets focus on the actual violations, not the tools. Exploits and social
engineering doesn't compromise: people do. Focus on the people who broke the
rules which make sure our country isn't manipulated in to an oligarchy.

~~~
deveac
_> Seriously. This isn't even bad....There is no need to blow normal research
and security work out of proportion._

Is normal security research done with the goal of finding/creating holes with
the purpose of keeping them secret in order to use them as attack vectors
without letting the owners of the compromised systems know about the
vulnerabilities?

What's bad about this is the purpose of the research (not to discover and
strengthen security, but instead to destroy it), combined with the
weaponization of it (the entire goal of doing the research is to use the
exploits), and the actor carrying out the attacks (the state).

It's obvious on its face why this is alarming.

I agree. When the intelligence community has to resort to this, I think the
everyman is ok:

>At the 2011 Jamboree conference, there were two separate presentations on
hacking the GID key on Apple’s processors. One was focused on non-invasively
obtaining it by studying the electromagnetic emissions of — and the amount of
power used by — the iPhone’s processor while encryption is being performed.
Careful analysis of that information could be used to extract the encryption
key. Such a tactic is known as a “side channel” attack. The second focused on
a “method to physically extract the GID key.”

Am I missing something? Isn't their targetting of Xcode as massive as if
they'd just announced they'd backdoored Gnu gcc?

I mean whether they've backdoored the regular version available to all or only
those in use by specific developers, the implication (to me) would be that
binaries/applications/etc produced would then be automatically backdoored or
at very least weakened?

Disclaimer: I know zip about Xcode or dev in the Apple ecosystem

_“Tearing apart the products of U.S. manufacturers and potentially putting
backdoors in software distributed by unknowing developers all seems to be
going a bit beyond ‘targeting bad guys.’ It may be a means to an end, but it’s
a hell of a means.”_

The trouble with the means justifying the ends, is that ends are fictions
invented to enable the telling of stories. Outside the structures required for
stories, there is only ever really the means.

Here's their mission statement:

"Preempt threats and further US national security objectives by collecting
intelligence that matters, producing objective all-source analysis, conducting
effective covert action as directed by the President, and safeguarding the
secrets that help keep our Nation safe."

Historically the CIA and NSA have a competitive relationship, they vie for the
same funding. I would think pursuing iPhone security would cross into the
NSA's domain and that they wouldn't appreciate it, however the CIA has a
budget 50% larger than the NSA and I'm sure they'd like to keep it that way by
staying relevant.

This is a great argument for "Gentoo Android".

While much of the iOS is Open Source or Free Software, the end-user can't
really inspect the source that went into their particular device.

Note that, to the extent that the CIA steals Apple secrets from foreign
sources, they may not be violating any US laws. However Apple does the vast
majority of its system software development in Cupertino, California.

My next phone is going to be an Android that enables me to completely replace
its firmware binary. While this does void the warranty, rather than having to
be concerned about potentially skanky jailbreak exploits, one more or less
just sets a flag with an Android SDK command-line tool, then you can install
your own firmware.

That will be of limited use in protecting me against hardware backdoors, but
at least it will let me pretend that America is still The Land Of The Free.

Among the reason I am so adamant about stuff like this, and that I use my real
name when I post about it so publicly, is that I am related to Roger Sherman,
the fourth signer of the US Declaration of Independence, as well as to William
Tecumseh Sherman and George B. McClellan, the two Generals-in-Chief of the
Union Army during the American Civil War.

I don't buy it. I really don't.

We know about the incredibly close ties between silicon valley and the
military. We know that the US government collects anything and everything, and
that US corporations are complicit (or made to be complicit) in the act.

It is most likely that Greenwald was leaked these documents to create a facade
of government-corporate animosity to revive trust in US corporations, all the
while there existing a backdoor to facilitate snooping.

~~~

The article explains that these are all documents from Snowden. So they're
simply taken from the full set that Greenwald has had since 2013, not any kind
of new leak.
