Apple Denies Systems Breach In Photo Leak

Hamsterdan notes that Apple has posted an update to its investigation into the recently celebrity photo leak, which was attributed to a breach of iCloud. Apple says the leak was not due to any flaw in iCloud or Find My iPhone, but rather the result of "a targeted attack on user names, passwords and security questions." Despite this, Wired reports that hackers on an anonymous web board have been openly discussing a piece of software designed for use by law enforcement. Whether it was involved in the celebrity attacks or not, it's currently being used to impersonate a user's device in order to download iCloud backups.

"For Apple, the use of government forensic tools by criminal hackers raises questions about how cooperative it may be with Elcomsoft. The Russian company’s tool, as Zdziarski describes it, doesn't depend on any 'backdoor' agreement with Apple and instead required Elcomsoft to fully reverse engineer Apple’s protocol for communicating between iCloud and its iOS devices. But Zdziarski argues that Apple could still have done more to make that reverse engineering more difficult or impossible." Meanwhile, Nik Cubrilovic has waded into the data leak subculture that led to this incident and provides insight into the tech and the thinking behind it.

      Use one very strong password for the password manager. That allows you to have hundreds of different passwords so each site you visit uses a different password and you don't need to remember them. If you use a strong enough password then you'll be fine.

      You need to take a step back and consider the actual threat. If you are going to post the ciphered content of your password database on the front page of Slashdot yes the cryptography better be done right.

      If you going to keep it on your desktop or on your phone and NOT send it over the network. Than I would say the value it affords you in being able to use longer passwords, with greater randomness, and unique passwords for every account is a win. The only anyone is going to get hold of it is if they pwn your computing device. If they do that than they don't need to beak the crypto they will just wait with the keylogger running for your to unlock it and collect the secret.

      At that point though you rather than $PUBLIC_WEBSITE have become the attackers target. Once we are talking about a targeted persistent attack, there is little any of us will do personally to be safe if our attackers are any better equipped/capable than script kiddies.

      A strong password CAN be easily remembered. How about remembering 10 and 11?

      "Ten!!!!!!!!!!!"

      That's 10 and eleven "!" characters.

      There are a number of ways to calculate password effectiveness. If you assume zero knowledge of the password characteristics, then the 290 million years the website you linked to calculated may be accurate.

      Hackers, however, have typically found that certain patterns are used by humans more frequently than others, and instead of brute-forcing the password from the beginning (following UTF-8 order " ", " ", " !"... etc.), you can instead skip a significant part of the overall password space by only testing these common patterns.

      I prefer this tool, which evaluates password entropy. The figures it comes up with do tend to presume that something about the structure of the password is known (i.e: in your example that it is a word followed by a repeating symbol), but IMO this is a good figure to base your password decisions off as it represents a worst-case scenario, and not the best-case scenario the tool you linked presumes.

      Using that tooling instead, your passwords strength and estimated crack time is as follows:

      • password: Ten!!!!!!!!!!!
      • entropy: 18.669
      • crack time (seconds): 20.836
      • crack time (display): instant
      • score from 0 to 4: 0
      • calculation time (ms): 3

      FWIW, (and purely for the sake of comparison) one of the passwords I use online has, according to this tool, an entropy of 61.819 and a crack time of 203355820622500.06s (about 6.4 million years). And yes, it's something I both change often and have memorized.

  6. Find My Friends password flaw by Noah+Haders · · Score: 5, Interesting
    You know, I'm really annoyed at Apple about this. They say that iCloud wasn't breached and it was a targeted account attack with weak passwords. But on Monday (the day after the pics were posted) they patched a flaw in Find My Friends where the account would be vulnerable to a dictionary attack:

    The vulnerability allegedly discovered in the Find my iPhone service appears to have allowed attackers to use this method to guess passwords repeatedly without any sort of lockout or alert to the target. Once the password has been eventually matched, the attacker can then use it to access other iCloud functions freely. A tool to exploit the weakness was uploaded to Github, where it remained for two days before being shared on Hacker News Apple patched the service at 3.20am PT today. While it’s possible that the timing was coincidental, an iCloud exploit being posted online just two days before the photos appeared, and being patched shortly after the story broke, makes this seem unlikely. Apple has not yet responded to a request for comment.

    http://9to5mac.com/2014/09/01/...

    so there was no icloud breach, but there was a bug that enabled a brute force attack. It's not known that this exploit was used on the celebrities, but a tool that exploits this bug was recently posted. Ok...

      It's not known that this exploit was used on the celebrities

      The pics were apparently circulating over a week ago in some parts of the Internet, and were, by all indications, collected over the course of several months from a variety of sources (i.e. not all of the celebrities are in the Apple ecosystem; a number of them use Android). The "iBrute" exploit code didn't become available until earlier this week.

      There's actually a fairly detailed breakdown of this and similar attacks already available, most of which rely on various social engineering techniques, basic detective work, or turning (ex-)friends of the celebrities against them to get malware installed or procure more intimate information (sometimes in exchange for receiving their own copies of the pics).

      Finally, pointing out that they're not responsible for the data being compromised is not the same as blaming the victims. As the article I linked mentions, in many cases these celebrities may not have ever fallen for a phishing attack or given their password to "tech support" over the phone. The only error they may have made was in keeping poor company.

    Apple obviously wants iCloud and your ITMS credentials to be the iGateway to your life and all your devices and whatnot. They also emphasize security, elegance, and ease of use in their advertising, and cater to a relatively upmarket audience, for the most part.

    Why, then, can you not even buy any serious security? Yes, they have 'two factor authentication', of the kind where you have a username, password, and they send you a temporary PIN to one of your devices; but money simply cannot buy a certificate authentication mechanism. Nor an RSA-fob or equivalent. Hell, your WoW character can be protected by a hardware auth fob; but your entire iLife can't?

    In the end(while it may well be true) Apple's insistence that the hack was based on guessing/gaining user credentials, rather than attacking Apple code, just doesn't matter. User credentials are always fairly vulnerable. If they want people to put their life 'in the cloud', they are going to have to do better than that(especially if they want celebrity users, since that's a userbase that more or less automatically includes insane stalkers).

It wasn't gathered all at once from a single attack on iCloud. It was just leaked all at once.

    I have no evidence of that-- just the rumor I've seen on a couple different sites-- but it makes more sense than a massive iCloud hack that scooped up all of these photos at once.
