Canadian Sovereignty threat Exercise: Apple

Scenario Overview

Apple iCloud Workstation (Scenario 1): A fully Apple-integrated macOS device enrolled via Apple Business Manager (ABM) and managed by a U.S.-based MDM (Jamf Pro or Microsoft Intune). The user signs in with an Apple ID, leveraging iCloud Drive for file sync and iCloud Mail for email, alongside default Apple services. Device telemetry/analytics and diagnostics are enabled and sent to Apple. System and app updates flow through Apple’s standard channels (macOS Software Update service and Mac App Store). FileVault disk encryption is enabled, and recovery keys may be escrowed with Apple or the MDM by default (for example, storing the key in iCloud, which Apple does not recommend for enterprise devicessupport.kandji.io).

Fully Sovereign Canadian Workstation (Scenario 2): A data-sovereign macOS device also bootstrapped via Apple Business Manager (for initial setup only) but then managed entirely in-country using self-hosted NanoMDM (open-source Apple MDM server) and Tactical RMM (open-source remote monitoring & management agent) hosted on Canadian soil. The user does not use an Apple ID for any device services; instead, authentication is through a local Keycloak SSO and all cloud services are on-premises (e.g. Seafile for file syncing, and a local Dovecot/Postfix mail server for email). Apple telemetry is disabled or blocked by policy/firewall – no crash reports, Siri/Spotlight analytics, or other “phone-home” diagnostics are sent to Apple’s servers. OS and app updates are handled manually or via a controlled internal repository (no automatic fetching from Apple’s servers). The Mac is FileVault-encrypted with keys escrowed to Canadian infrastructure only, ensuring Apple or other foreign entities have no access to decryption keys.

Telemetry, Update Channels, and Vendor Control

Apple-Facing Telemetry & APIs (Scenario 1): In this environment, numerous background services and update mechanisms communicate with Apple, providing potential vendor-accessible surfaces. By default, macOS sends analytics and diagnostic data to Apple if the user/organization consents. This can include crash reports, kernel panics, app usage metrics, and morenews.ycombinator.com. Even with user opt-outs, many built-in apps and services (Maps, Siri, Spotlight suggestions, etc.) still engage Apple’s servers (e.g. sending device identifiers or queries)news.ycombinator.comnews.ycombinator.com. The Mac regularly checks Apple’s update servers for OS and security updates, and contacts Apple’s App Store for application updates and notarization checks. Because the device is enrolled in ABM and supervised, Apple’s ecosystem has a trusted foothold on the device – the system will accept remote management commands and software delivered via the Apple push notification service (APNs) and signed by Apple or the authorized MDM. Available surfaces exploitable by Apple or its partners in Scenario 1 include:

Sovereign Controls (Scenario 2): In the Canadian-sovereign setup, most of the above channels are shut off or localized, drastically reducing Apple (or U.S. vendor) surfaces:

Summary of Vendor-Controlled Surfaces: Below is a side-by-side comparison of key control/telemetry differences:

Feasible Exfiltration Strategies Under Lawful Vendor Cooperation

Under a lawful FISA or CLOUD Act scenario, a “red team” (as a stand-in for a state actor with legal leverage) might attempt covert one-time extraction of files, emails, and synced data. The goal: get in, grab data, get out without tipping off the user or local SOC, and without leaving malware behind. We analyze how this could be done in each scenario given the available vendor cooperation.

Scenario 1 (Apple-Integrated) – Potential Exfiltration Paths:

  1. Server-Side Data Dump (No Endpoint Touch): The simplest and stealthiest method is leveraging Apple’s access to cloud data. Apple can be compelled to export the user’s iCloud data from its servers. This includes iCloud Mail content, iCloud Drive files, iOS device backups (if the user’s iPhone is also in the ecosystem), notes, contacts, calendars, and so onapple.comapple.com. Because the user in Scenario 1 relies on these services, a large portion of their sensitive data may already reside in Apple’s cloud. For example, if “Desktop & Documents” folders are synced to iCloud Drive (a common macOS setting), nearly all user files are in Apple’s data centers. Apple turning over this data to law enforcement would be entirely invisible to the user – it’s a server transaction that doesn’t involve the Mac at all. Detection risk: Virtually none on the endpoint; the user’s Mac sees no unusual activity. The organization’s SOC also likely has zero visibility into Apple’s backend. (Apple’s policy is not to notify users of national security data requestspadilla.senate.gov, and such requests come with gag orders, so neither the user nor admins would know.) Limitations: This only covers data already in iCloud. If the user has files stored locally that are not synced, or uses third-party apps, those wouldn’t be obtained this way. Also, end-to-end encrypted categories (if any are enabled) like iCloud Keychain or (with Advanced Data Protection on) iCloud Drive would not be accessible to Apple – but in typical managed setups ADP is off, and keychain/passwords aren’t the target here.

  2. MDM-Orchestrated Endpoint Exfiltration: For any data on the Mac itself (or in non-Apple apps) that isn’t already in iCloud, the red team could use the MDM channel via the vendor’s cooperation. As noted, Jamf or Intune can remotely execute code on managed Macs with high privilegesi.blackhat.com. Under lawful order, the MDM operator could deploy a one-time exfiltration script or package to the target Mac. For instance, a script could recursively collect files from the user’s home directory (and any mounted cloud drives), as well as export Mail.app local messages, then send these to an external drop point (or even back up to a hidden location in the user’s iCloud, if accessible, to piggyback on existing traffic). Because this action is happening under the guise of MDM, it uses the device’s built-in management agent (e.g., the Jamf binary, running as root). This is covert in the sense that the user gets no prompt – it’s normal device management activity. If Intune is used, a similar mechanism exists via Intune’s shell script deployment for macOS or a “managed device action.” The payload could also utilize macOS’s native tools (like scp/curl for data transfer) to avoid dropping any new binary on disk. Detection risk: Low to moderate. From the device side, an EDR (Endpoint Detection & Response) agent might flag unusual process behavior (e.g. a script compressing files and sending data out). However, the script could be crafted to use common processes and network ports (HTTPS to a trusted cloud) to blend in. Jamf logs would show that a policy ran, but typically only Jamf admins see those logs. If the MDM vendor is acting secretly (perhaps injecting a script run into the Jamf console without the organization’s knowledge), the org’s IT might not catch it unless they specifically audit policy histories. This is a plausible deniability angle – since Jamf/Intune have legitimate admin access, any data exfil might be viewed as an approved IT task if noticed. The local SOC would need to be actively hunting for anomalies in device behavior to catch it (e.g. sudden outgoing traffic spike or a script process that isn’t normally run). Without strong endpoint monitoring, this could sail under the radar.

  3. Apple Update/Provisioning Attack: Another vector is using Apple’s control over software distribution. For example, Apple could push a malicious app or update that the user installs, which then exfiltrates data. One subtle method: using the Mac App Store. With an Apple ID, the user might install apps from the App Store. Apple could introduce a trojanized update to a common app (for that user only, via Apple ID targeting) or temporarily remove notarization checks for a malicious app to run. However, this is riskier and more likely to be noticed (it requires the user to take some action like installing an app or might leave a new app icon visible). A more targeted approach: Apple’s MDM protocol has a feature to install profiles or packages silently. Apple could coordinate with the MDM to push a new configuration profile that, say, enables a hidden remote access or turns on additional logging. Or push a signed pkg that contains a one-time agent which exfiltrates data then self-deletes. Since the device will trust software signed by Apple’s developer certificates (or enterprise cert trusted via MDM profile), this attack can succeed if the user’s system doesn’t have other restrictions. Detection risk: Moderate. An unexpected configuration profile might be noticed by a savvy user (they’d see it in System Settings > Profiles), but attackers could name it innocuously (e.g. “ macOS Security Update #5”) to blend in. A temporary app or agent might trigger an antivirus/EDR if its behavior is suspicious, but if it uses system APIs to copy files and send network traffic, it could pass as normal. Modern EDRs might still catch unusual enumeration or large data exfil, so the success here depends on the target’s security maturity.

  4. Leveraging iCloud Continuity: If direct device access was needed but without using MDM, Apple could also use the user’s Apple ID session. For example, a lesser-known vector: the iCloud ecosystem allows access to certain data via web or APIs. Apple (with a warrant) could access the user’s iCloud Photos, Notes, or even use the Find My system to get device location (though that’s more surveillance than data theft). These aren’t exfiltrating new data from the device per se, just reading what’s already synced. Another trick: If the user’s Mac is signed into iCloud, Apple could potentially use the “Find My Mac – play sound or message” feature or push a remote lock/wipe. Those are destructive and not useful for covert exfiltration (and would absolutely be detected by the user), so likely not considered here except as a last resort (e.g. to sabotage device after exfil).

In summary, Scenario 1 is rich with covert exfiltration options. Apple or the MDM provider can leverage built-in trust channels (iCloud, MDM, update service) to retrieve data or run code, all under the guise of normal operation. The user’s reliance on U.S.-controlled infrastructure means a lawful order to those providers can achieve the objective without the user’s consent or knowledge.

Scenario 2 (Sovereign Setup) – Potential Exfiltration Paths:

In Scenario 2, the usual “easy” buttons are mostly gone. Apple cannot simply download iCloud data (there is none on their servers), and they cannot silently push code via Jamf/Intune (the MDM is controlled by the organization in Canada). The red team must find alternative strategies:

  1. Canadian Legal Cooperation or Warrant: Since the device and its services are all under Canadian control, a lawful approach would be to go through Canadian authorities – essentially using MLAT (Mutual Legal Assistance) or CLOUD Act agreements (if any) to have Canada serve a warrant on the organization for the data. This is no longer covert or strictly a red-team tactic; it becomes an overt legal process where the organization would be alerted (and could contest or at least is aware). The spirit of the scenario suggests the adversary wants to avoid detection, so this straightforward legal route defeats the purpose of stealth. Therefore, we consider more covert vendor cooperation workarounds below (which border on active intrusion since no willing vendor exists in the U.S. to assist).

  2. Apple’s Limited Device Access: Apple’s only touchpoint with the Mac is ABM/APNs. As discussed, forcing a re-enrollment via ABM would alert the user (full-screen prompts)support.apple.com, so that’s not covert. Apple’s telemetry is blocked, so they can’t even gather intel from crash reports or analytics to aid an attack. Software updates present a narrow window: if the user eventually installs a macOS update from Apple, that is a moment Apple-signed code runs. One could imagine an intelligence agency attempting to backdoor a macOS update generally, but that would affect all users – unlikely. A more targeted idea: if Apple knows this specific device (serial number) is of interest, they could try to craft an update or App Store item that only triggers a payload on that serial or for that user. This is very complex and risky, and if discovered, would be a huge scandal. Apple historically refuses to weaken its software integrity for law enforcement (e.g. the Apple–FBI case of 2016 over iPhone unlockingen.wikipedia.org), and doing so for one Mac under secrecy is even more far-fetched. In a theoretical extreme, Apple could comply with a secret order by customizing the next minor update for this Mac’s model to include a data collection agent, but given Scenario 2’s manual update policy, the organization might vet the update files (diffing them against known good) before deployment, catching the tampering. Detection risk: Extremely high if attempted, as it would likely affect the software’s cryptographic signature or behavior noticeably. Thus, this path is more hypothetical than practical.

  3. Compromise of Self-Hosted Tools (Supply Chain Attack): With no willing vendor able to assist, an attacker might attempt to compromise the organization’s own infrastructure. For instance, could they infiltrate the NanoMDM or Tactical RMM servers via the software supply chain or zero-day exploits? If, say, the version of Tactical RMM in use had a backdoor or the updater for it was compromised, a foreign actor could silently gain a foothold. Once in, they could use the RMM to run the same sort of exfiltration script as in Scenario 1. However, this is no longer “lawful cooperation” – it becomes a hacking operation. It would also be quite targeted and difficult, and detection risk depends on the sophistication: a supply chain backdoor might go unnoticed for a while, but any direct intrusion into the servers could trigger alerts. Given that Scenario 2’s premise is a strongly secured environment (likely with a vigilant SOC), a breach of their internal MDM/RMM would be high risk. Nonetheless, from a red-team perspective, this is a potential vector: If an attacker cannot get Apple or Microsoft to help, they might target the less mature open-source tools. E.g., Tactical RMM’s agent could be trojanized to exfil data on next update – but since Tactical is self-hosted, the org controls updates. Unless the attacker compromised the project supply (which would then hit many users, again noisy) or the specific instance, it’s not trivial.

  4. Endpoint Exploits (Forced by Vendor): Apple or others might try to use an exploit under the guise of normal traffic. For example, abuse APNs: Apple generally can’t send arbitrary code via APNs, but perhaps a push notification could be crafted to exploit a vulnerability in the device’s APNs client. This again veers into hacking, not cooperation. Similarly, if the Mac uses any Apple online service (maybe the user still uses Safari and it contacts iCloud for safe browsing, etc.), Apple could theoretically inject malicious content if compelled. These are highly speculative and not known tactics, and they carry significant risk of detection or failure (modern macOS has strong security against code injection).

In summary, Scenario 2 offers very limited avenues for covert exfiltration via vendor cooperation – essentially, there is no friendly vendor in the loop who can be quietly compelled to act. Apple’s influence has been minimized to the point that any action on their part would likely alert the user or fail. The contrast with Scenario 1 is stark: what was easy and silent via cloud/MDM in the first scenario becomes nearly impossible without tipping someone off in the second.

Detection Vectors and SOC Visibility

From a defensive viewpoint, the two scenarios offer different visibility to a local Security Operations Center (SOC) or IT security team, especially in a public-sector context where audit and oversight are critical.

Risks, Limitations, and Sovereignty Impacts

Finally, we assess the broader risks and sovereignty implications of each setup, with some context for Canadian public-sector use:

Side-by-Side Risk & Visibility Comparison

To encapsulate the differences, the table below assigns a qualitative Detection Risk Level and notes SOC Visibility aspects for key attack vectors in each scenario:

Canadian Data Residency & Sovereignty: In essence, Scenario 2 is built to enforce Canadian data residency and blunt extraterritorial legal reach. As a result, it significantly reduces the risk of a silent data grab under U.S. FISA/CLOUD Act authority. Scenario 1, by contrast, effectively places Canadian data within reach of U.S. jurisdiction through the involved service providers. This is why Canadian government strategists advocate for sovereign clouds and control over sensitive infrastructure: “All of our resources should be focused on regaining our digital sovereignty… Our safety as a country depends on it.”micrologic.ca. The trade-off is that with sovereignty comes responsibility – the need to maintain and secure those systems internally.

Conclusion

Scenario 1 (Apple iCloud Workstation) offers seamless integration but at the cost of giving Apple (and by extension, U.S. agencies) multiple covert avenues to access or exfiltrate data. Telemetry, cloud services, and remote management are double-edged swords: they improve user experience and IT administration, but also provide channels that a red team operating under secret legal orders can quietly exploit. Detection in this scenario is difficult because the attacks abuse trusted Apple/MDM functionality and blend with normal operations. For an adversary with lawful access, it’s a target ripe for the picking, and for a defender, it’s a scenario where you are often blindly trusting the vendor.

Scenario 2 (Fully Sovereign Workstation) drastically limits those avenues, embodying a zero-trust approach to vendor infrastructure. By keeping the device mostly self-contained (no routine calls home to Apple) and all services in-country, it forces any would-be data extraction to go through the organization’s own gateways – where it can ideally be detected or stopped. This setup aligns with Canada’s push for digital sovereignty and protection against foreign interferencemicrologic.camicrologic.ca. The security team has much greater visibility and control, but also a greater burden of maintenance and vigilance. In a red-team simulation, Scenario 2 would frustrate attempts at undetected exfiltration; it might require the “attacker” to switch to more overt or risky methods, which stray outside the bounds of silent lawful cooperation.

In summary: The Apple iCloud scenario is high-risk from a sovereignty perspective – it’s like living in a house with backdoors you can’t lock, hoping nobody with a master key uses them. The Sovereign Canadian scenario is more like a well-fortified compound – fewer backdoors, but you must guard the front and maintain the walls yourself. Each approach has implications for security monitoring, incident response, and legal exposure. As of October 2025, with increasing emphasis on data residency, the trend (especially for public sector) is toward architectures that resemble Scenario 2, despite the added effort, because the cost of silent compromise is simply too high in an environment where you might never know it happened until it’s too latemicrologic.camicrologic.ca.
