Apple has all but declared corporate war on Facebooks designs to track people online. Activates the device with the given activation record in 'session' mode. These mechanisms are use case specific, and dont provide a general-purpose form of attestation with which apps could build their own authentication protocols. The Mac is activation locked, probably to a personal Apple ID. These keys can be unlocked using either a biometric factor or a PIN (thus proving user presence), and do not necessarily require that any biometric factor be enrolled to unlock the key. Apples goal to have as much logging on as much of the time as possible is great for admins, because more logging often means more insight that can be used to solve problems or to learn. ticket first to discuss the idea upfront to ensure less effort for everyone. Apple goes one step further, and seals this set of entitlements into the app, under the app bundle signature. Apple hid the WebAuthn implementation of key attestation behind a SPI in the new (as of Big Sur and iOS 14) AppAttest framework, AppAttest_WebAuthentication_AttestKey. The more you learn about them, the more useful logs become for both troubleshooting and for discovering how and why things happen on a systemand that makes the log command an essential tool for any Apple admin. omissions and conduct of any third parties in connection with or related to your use of the site. Loading and analyzing the dyld_shared_cache from macOS Big Sur on x86-64 took about 7 hours on my Linux VM, so if you plan to go down this path you had better start this in the morning and have a full day of other work planned. hbspt.cta._relativeUrls=true;hbspt.cta.load(5058330, '8bed3482-30c4-4ee2-85a9-6f0e2149b55c', {"useNewLoader":"true","region":"na1"}); The industry's first MDM with a pre-built library of security controls. activation_record. ) This project is an independent software library and has not been authorized, What this does is straightforward: its simply showing the logs on the system. Heres how Apple describes it: Activation Lock helps you keep your device secure, even if its in the wrong hands, and can improve your chances of recovering it. His ten-year background spans topics from tech to culture and includes work for the Seattle Times, the Houston Press, Medium's OneZero, WebMD, and MailChimp. also included in the repository in the COPYING file. )Here is the same log entry, but with private data logging enabled for the com.apple.opendirectoryd subsystem, using the Open Directory private data profile: Note that this time the username ladminwas logged.We recommend enabling private data logging only for specific subsystems, and only when absolutely necessary. Mobileactivationd is taken from iOS 12.4.2. Apple Footer. MAC addresses work with the card in your device that lets it connect wirelessly to the internet, called a Network Interface Controller (NIC). Apples apps can ask the SEP generate and attest a new key, the UIK signs an attestation ticket to be submitted to one of Apples attestation authorities. Modifying this control will update this page automatically. RELATED: Wi-Fi vs. Ethernet: How Much Better Is a Wired Connection? P. Phillips, call If the attestation checks out, the relying party will store the key handle for future authentication attempts, such as the next time the enrolled user logs in. Its security critical tasks include managing communication with the biometric sensor, performing biometric template extraction and matching, handling user identity keys and managing data encryption keys and hardware. Each app that uses the keychain must specify a keychain access group in its entitlements -- this identifier could be shared among apps developed by the same company. While this is an excellent outcome, one has to ask how anonymous a user is with respect to one particular company: Apple itself. Activates the device with the given activation record. Apple also has a few special keychain access groups, like lockdown-identities, representing activation-related keys. These attestation authorities take metadata collected by macOS/iOS and match it up with data in the encrypted attestation ticket generated by the SEP and device metadata collected in the factory and stored by Apple. Mobileactivationd is taken from iOS 12.4.2. any proposed solutions on the community forums. Select your country and language from the initial setup page. This log indicates a successful authentication event, such as when successfully unlocking a preference pane in System Preferences: By default, the user name of the user is masked as . Mac administrators within organizations that want to integrate with the current Apple ecosystem, including Windows administrators learning how to use/manage Macs, mobile administrators working with iPhones and iPads, and mobile developers tasked with creating custom apps for internal, corporate distribution. For example, how did we know that AirDrop uses that particular subsystem and category? Is it normal for my computer to have that? When reviewing logs, you may see entries that contain the string , sometimes accompanied by a unique identifier (or UUID). In this guide, well cover some of the basics of Apples unified logging system, go over how to read the logs using the log command, and provide some practical examples of how to filter log messages to find the ones that are most important to you. More. There are other interesting entitlements, like the mobileactivationd entitlements, also used to retrieve metadata needed to request attestation from AAA. But since you've said that you also have it in your activity monitor as well (is that what you mean, isn't it? Until Apple exposes this functionality as some daemon that can be called by third-party apps, this really nice feature will be a Safari exclusive. These keys are nevertheless very difficult for an attacker to clone, raising the bar against phishing attacks and other remote compromise risks. AppAttests public APIs include the new App Attestation feature, so it would make sense to reuse some of the same code. Retrieves the activation info required for device activation in 'session' mode. Thats because of Apples stated goal of doing as much logging as much of the time as possible. Please To do that, you can run the command: Youll likely be surprised at the sheer number of messages that appear on your screen just from the last minute. The SPI AppAttest_WebAuthentication_AttestKey calls AppAttest_Common_Attest, after performing some basic sanity checks. Other identities, such as the Silicon Identity Key (SIK), are unique to a particular device. But it can also make it difficult to find the signal in all the noise. Any WebAuthn authenticator returns two important blobs of data to the relying party: The attestationObject for SEP-based attestation consists of 3 fields: The attStmt array of certificates starts from the certificate subordinate to Apples WebAuthn Root CA, down to an end entity certificate that represents the WebAuthn credential itself. This site contains user submitted content, comments and opinions and is for informational purposes Apple disclaims any and all liability for the acts, Among other things, that meant compressing log data and providing robust ways to manage log message lifecycles.). They switched MDM platforms to JAMF early this year. available command line options: We welcome contributions from anyone and are grateful for every pull request! https://git.libimobiledevice.org/libideviceactivation.git, https://github.com/libimobiledevice/libideviceactivation.git, https://github.com/libimobiledevice/libideviceactivation/issues, https://lists.libimobiledevice.org/mailman/listinfo/libimobiledevice-devel, https://github.com/posixninja/ideviceactivate/, Try to follow the code style of the project, Commit messages should describe the change well without being too short, Try to split larger changes into individual commits of a common domain, Use your real name and a valid email address for your commits. The manufacturer issues a certificate to the device in the factory, a sort of proof that the device is authentic and keeps keys safe and secure as the WebAuthn standard specifies. Its also easyto find the MAC address on a Mac computer. The activation record plist dictionary must be obtained using the activation protocol requesting from Apple's https webservice. But what are they exactly, and how are they different from IP addresses? The specification is part of the next iteration of the FIDO Alliances suite of standards, Universal Second Factor or U2F. However, no pricing is listed on the website, and we cant vouch for it in any way. These include: The Webkit repository includes all the tools and build system hooks required to build the internal version of Safari. This does create a bit more complexity for the relying party when it verifies the integrity of the attestation metadata, but means every rpIdHash would be unique. Thank you so much for your answer. You use your network account user name and password to log in, whether or not youre connected to the network.

If you spend enough time reverse engineering Apples DeviceIdentity private framework, youll see several other entitlements related to key attestation. Attestation is just one step in a larger cryptographic protocol. This ticket serves as proof the SEP generated, manages and protects this new key. Safari doesnt do anything special when generating keys for use in WebAuthn, beyond protecting a key from being used by a different origin. granting the user permission to use the startup disk since that is the only option I can get other than wipe the device. also included in the repository in the COPYING.LESSER file. How a Mac and a Windows-Based PC Are Different . Copyright 2023 Apple Inc. All rights reserved. The sysdiagnose tool, which runs automatically when you file feedback with Apple, even automatically generates a system log archive for Apple engineers to analyze (named system_logs.logarchive in the root of the sysdiagnose folder). The SEP is a separate ARM Cortex-A CPU, with isolation from the ARM CPU cores running iOS. Combine Kandji with the rest of your software stack to save even more time and effort. Retrieves the activation info required for device activation. Paging u/appletech752 because I'd like to get a definitive answer on this.. I've seen a lot of posts around on how to back up your activation files. Activates the device with the given activation record. Apple Configurator 2 from the Mac App Store is also useful for streaming the live system log of a connected iOS device, which can be useful for troubleshooting issues as they happen on iOS; Xcode can also be used for that purpose.). When a device requests an anonymous AAA attestation, the request includes several key pieces of information: This gives AAA the ability to reconstruct most of the data that went into producing the nonce that is wrapped in the SEP attestation ticket, without disclosing the client data portion of the attestation. sponsored, or otherwise approved by Apple Inc. DFU Reviving (succeeds, but activation still fails), attempting to activate on different networks (both Wi-Fi and cable). When unified logging was first introduced at WWDC 2016, it was a pretty radical and bold change. When transferring encrypted or signed data across an insecure channel, you need some assurance that a previous communication isnt being replayed by an attacker.

Apple immediately discontinued all Authentec parts, and cancelled all relationships they could. But first, what is the Secure Enclave Processor, and how does this provide unique security characteristics to Apple devices? If using Mac Provisioner or another wrapper around startosinstall there's probably a way to configure it to include the package during OS install. only. Internet Connection Not Working? If the login window displays a list of users, your mobile account name is included in the list, and you can click it to log in (you dont need to click Other, and then enter your account name). For those of you considering WebAuthn as an authentication control, remember that anyone who possesses a device or has access to the device remotely would be able to use these credentials. Starts a new mobileactivation service on the specified device and connects to it. So a MAC address of 2c549188c9e3, for example, would be displayed 2C:54:91:88:C9:E3 or 2c-54-91-88-c9-e3. If you cant remember your Apple ID email. Researchers from information-security consulting firm Positive Technologies looked at 11 different models of ATMs made.

A subreddit for all things related to the administration of Apple devices. 1-800-MY-APPLE, or, Sales and Patch: link 14 8 8 comments Add a Comment This avoids Apple ever possessing the plaintext relying party ID, and makes it hard for Apple to determine the relying party without going to some effort. AppAttest_Common_ValidateEntitlements checks for the following entitlements: This confirms why Safari added these entitlements: theyre required to call the AppAttest SPI. Its up to the relying party to verify the attestation, and decide whether or not to accept the WebAuthn enrollment attempt. This tells the log command that we want to filter the log messages; what we include between the next set of single quotes becomes the filter. FlannelAficionado 5 mo. A few useful processes, subsystems, and categories for Apple admins are listed below. WebAuthn on Safari has its keys tagged with the com.apple.webkit.webauthn access group. This site contains user submitted content, comments and opinions and is for informational purposes Before signing an app, Apple vets the list of entitlements the app requests -- pick an entitlement Apple doesnt want you to have, and they wont sign your app. This relatively short predicate filter is a great one to keep in your toolbox for looking at AirDrop logs. Before you start, ask your network account server administrator to set up a mobile user account for you. I am guessing the Mosyle unenroll messed with users who have a secure token, ie. There was a problem preparing your codespace, please try again. (adsbygoogle = window.adsbygoogle || []).push({}); Activation Lock is a security feature that is turned on when Find My is enabled. One consideration though: Apple will get a hash of the relying party ID, the rpIdHash field of the authenticator data. Before moving to The Bayou City, John earned a B.A. If your laptop has an ethernet port and Wi-Fi, for example, it would have different MAC addresses for the Wi-Fi connection and the Ethernet connection. The sequel will be a straightforward exercise in analyzing private frameworks included in macOSs dyld_shared_cache using IDA. If you need to find the MAC address for your device, you can usually do it by going into the settings menu. The SEP is the gatekeeper for a multitude of identities associated with an Apple device. Scan this QR code to download the app now. You can pass different time modifiers into the --last option: --last 1h (the last hour) or --last 1d (the last day), for example. This would cement the position of Apples platform as a leader in user and enterprise identity management capabilities, enabling sophisticated identity management applications. What Is Bridge Mode on a Router, and Why Should You Use It? iOS-Hacktivation-Toolkit / bypass_scripts / mobileactivationd_12_4_7 / mobileactivationd Go to file Go to file T; Go to line L; Copy path Copy permalink; This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. talking to Apple's webservice alongside a command-line utility named It sounds like a malware that tries to active some things on my Mac. This is where predicate filtering becomes enormously useful. MAC addresses are always a 12 digit hexadecimal number, with the numbers separated every two digits by a colon or hyphen. The UIK is a P-256 key pair derived from the UID, resulting in an asymmetric key pair that can be traced back to an individual activation of a device by a user. You'll need to coordinate with the user to get the activation lock removed. Note: The Authentec acquisition was the second time Apple bought a critical vendor for a design I was working on. However, the core goal of the SEP remains unchanged: to provide a secure and trusted (by Apple) store for keys, identity secrets and biometric templates. What is mobileactivationd mac. mobileactivationd Welcome to Apple Support Community A forum where Apple customers help each other with their products. Apple, iPhone, iPad, iPod, iPod Touch, Apple TV, Apple Watch, Mac, iOS, However, it seems these posts have a lot of conflicting information and disagree on which files you need and where they live- I've looked around on my phone and I'm not seeing half the stuff people say I should have (or not where they say it . captured in an electronic forum and Apple can therefore provide no guarantee as to the efficacy of booting to a USB installer for macOS to upgrade the OS. Activation Lock is a security feature that is turned on when Find My is enabled. any proposed solutions on the community forums. Disconnects a mobileactivation client from the device and frees up the mobileactivation client data. These are all great steps for user privacy, at least from companies other than Apple. This is called MAC filtering. If nothing happens, download Xcode and try again. When you see this, something on the system has tried to log data that could potentially identify a user, the network, or another piece of dynamic information that could be considered private in some way. Create and configure mobile accounts on Mac A mobile account lets you access your server-based network user account remotely. osquery 4.1.1 / 4.0.2 What steps did you take to reproduce the issue? Consider a log entry like this: In this case, com.apple.ManagedClient is the subsystem, OSUpdate is the category, and mdmclient is the process. By sealing the hash of these blobs of data in the end entity certificate, we can verify that these structures received in the attestation payload have not been tampered with, showing we can have some degree of trust in this metadata originating from an Apple device not being replayed nor tampered with. With the --start and --end options plus specific timestampsin the formats YYYY-MM-DD, YYYY-MM-DD HH:MM:SS, or YYYY-MM-DD HH:MM:SSZZZZZyou can very narrowly filter the list of messages based on timestamp. This would still provide enough protection to prevent an attacker from being able to trick AAA into signing an attestation for a different relying party altogether. Apple has been reticent to expose SEP key attestation to third party . When Apple introduced unified logging, it dubbed it logging for the future. It set out to create a common logging system for all of its platforms with the following goals: Many admins might still think of looking for log messages in the common Unix flat files in /var/log/.
