Is the DEA Lying About iMessage Security?

First time accepted submitter snobody writes "Recently, an article was posted on Slashdot about the claim that law enforcement made about being frustrated by their inability to decrypt messages using Apple's iMessage. However, this article on Techdirt suggests that the DEA may be spewing out disinformation. As the Techdirt article says, if you switch to a new iDevice, you still are able to access your old iMessages, suggesting that Apple has the key somewhere in the cloud. Thus, if law enforcement goes directly to Apple, they should be able to get the key."

      This assumes a certain architecture. If the cryptosystem is strong, there is probably a frequent key rotation schedule, in which, the same key that encrypted past messages will potentially be replaced in the future by the time any new messages are exchanged.

      It would be ideal, if some portion of this key were secured by the password, e.g. a SCRPT, BCRYPT or PBKDF2 hash of the password, is part of the secret material required to decrypt the key on the client, and any change of the user's password results in key rotation.

      It is conceivable that Apple could design a system, in which, the keys would be available on multiple of your devices (because you knew an additional secret), but not available to Apple, to extract or find out what the key is (because Apple denies themselves access to the secret)

      Do I think it's designed that way? No... it would not happen by coincidence, for sure.

    I think one of the main problems law enforcement has with iMessages is that it is ridiculously easy to get a pen register from a telco for a phone number. This is a list of the calls made to/from that number and a list of SMS/MMS to/from that number. iMessage bypasses SMS/MMS if both the origin and destination device are iMessage capable, so those interactions do not show in a pen register. The same could be said for many other text/chat services, but iMessage is the default texting client for a large number of people and does not require the user to do anything special to message others without the telco knowing, unlike many other services.

    iMessage isn't that special, the memo could just as easily been talking about FaceBook messages, which also won't appear in a pen register.

    Unless the DEA is actively 'leaking' in order to attempt to move people into a vulnerable channel with a false sense of security(not impossible; but I'm inclined to suspect that the higher level drug runners take their paranoia seriously, or they wouldn't have lasted long enough to level up, and the lower level ones are probably more often foiled by the fact that they need to solicit customers, any one of which could be a plant), I'd be inclined to a more prosaic explanation.

    With SMS, architectural security during transmission is somewhere between pitiful and nonexistent and the entity that handles the messages during their voyage is the phone company, which has substantial legal incentives to, and a long history of, supine cooperation with the authorities.

    With iMessage, it looks pretty much like SMS on the handset; but it's all just data to the telco, and Apple presumably included some SSL/TLS or similar implementation that isn't totally broken, meaning that going through the telco is totally useless(this would also be why the leaked memo specifically mentioned that iMessages sent to non-Apple devices, which would be crunched into SMS at some stage, were still often recoverable).

    The fact that Apple can, apparently, retrieve your iMessage history for you suggests that, indeed, a subpoena of Apple would leave you in the open; but I imagine that the DEA is much more familiar with, and pleased by, the 'service-oriented' attitudes of the phone companies, who are extremely forthcoming with customer information, with very low bars to clear, and minimal pesky judicial process.

    Certainly not a good idea to trust anything that the service operator can 'recover' or 'restore' for you to be secure(since it can't possibly be); but the DEA jackboots probably do encounter significantly greater hassle with a message that is never available to the notoriously friendly telcos. You are still up shit creek if they are building a case against you specifically(or if Apple caves and starts providing bulk access at some future time); but casual fishing is likely to be more difficult.

    The issue is not that the DEA cannot lawfully acquire the messages... It's that THEY HAVE TO ASK , EVERY TIME.

    Most taps are just "wide open" until the warrant expires and the telco turns the tap off... There is very little oversight. Many online services give law enforcement more of an "open ticket" to keep coming back for email or Facebook as often as they need.

    The DEA lies about everything else. Why would this be any different? The very fact that the DEA exists is an affront to personal liberty; We have decades of detailed records of them spreading falsehoods, destroying families, in general doing far more harm than drugs ever did or ever could.

    DEA Informers: They lie about who they are, what they do, what their intent is -- and just about anything else they're asked. This is who they are. Liars. But that's not all they are. They're also as dangerous as any government agent you can imagine, wholly without concern for anyone but themselves.

    DEA agents: They lie about where the danger comes from; they lie about toxicity; they lie about addictiveness. They lie about consequences (they ARE the primary consequences), and they have been known to attempt to trade your personal honor for your freedom if you fall into their hands. They created the violence underlying the black market drug trade; they created the black market itself. They're not shy of interfering with other sovereign countries, nor of playing fast and loose with our own "justice" system.

    So when a DEA "anything" tells you something, you're best off assuming they're lying. It's what they do. Aside from destroying families, that is. If they're not lying, they're likely trying to hurt you some other way. Get away and stay away. Nothing truly good can ever come of contact with people so bereft of personal honor -- or so outright stupid -- that they would work for the DEA.

    To heck with them. And the laws they rode in on. And those who made the laws. And those in the general population who thought, and perhaps still think, agencies like the DEA were ever a good idea.

      Glenn Greenwald debated GWB's drug czar on the question of whether the US should legalize all drugs. http://vimeo.com/32110912 Greenwald identified the following costs, all of which we pay due to the drug war, all of which would go away if reason prevailed, and challenges prohibitionists to address why these costs are worth it. Listen closely to Portugal's experience with decriminalizing all drugs (evaporation of the following costs, slight increase in usage rates of some drugs (but less of an increase than neighbor countries during the same time period), a DROP in usage rates of drugs among young people, reduction in the spread of HIV etc, returning people who use drugs to the productive economy rather than making them burdensomely unemployable, acceptance of the police as a helpful organization rather than an enemy, which leads to the police being able to actually investigate real crime).

      If you are unable to address those costs with evidence based information, we will know your opinion is based on mere personal dislike for drugs and drug users, i.e., moralizing, fear mongering, and prejudice:

      1. The US is the world's largest prison state on a per capita basis AND on an absolute basis. We hold 25% of the world's prisoners despite having only 5% of the world's population.

      2. The War on Drugs is undeniably racist. All ethnic groups use drugs at essentially equal levels, but certain minorities comprise the greatest number by far of those convicted.

      3. Economic costs in the 100s of billions and yet no reduction in drug use.

      4. Drug war has spawned the privatised prison industry.

      5. The erosion of civil liberties experienced in the last 40 years has been rooted in the drug war.

      6. Militarization of the police force which turns it from an organization community members will trust for help, into one which is feared and deemed an enemy. This hinders solving crime.

      7. International resentment to the US based on US demands that other countries criminalize their population and take on what are seen as unnecessary social and economic costs.

      8. Extreme violence due to the fact that in a black market, only criminals will participate and criminals use violence to secure market share ("you don't see Budweiser and Heinken shooting each other over territory").

      9. Drug war breeds contempt for the law, because millions of people use drugs, even frequently, without any consequences at all (depending on one's demographic profile).

      10. The drug war destroys the lives of the very individuals the government claims it wishes to help because as felons, they become unemployable. So while imprisoned and after release, such people are unable to provide for their families and being separated from families is highly corrosive to families.

      7. Last time I checked, drug use was illegal (and enforced as such) in most countries around the world, so I have no idea what you're referring to.

      8. Poor logic. Again, should we legalize all form of criminal acts for fear of what the black market will do? Laws exist for morale reasons. Selling drugs is like selling Alcohol to a known Alcoholic. It is highly addictive and prays on people's weakness.

      9. Many people experiment, but most move on and hold nothing but respect for law enforcement. Most people don't smoke pot and do crack through the rest of their life.
