ASUS Zenfone 11 Ultra (AI2401 H)

Security Evaluation

1. Device Security

Criterion	Value	Proof	Comment
Known hardware tampering	Rare	[1] 🔗 Proof	An enclosed portable phone with accessible external interfaces and biometric unlocking. The physical enclosure limits casual board access but is not documented as a whole-device tamper-proof boundary. Rare is a partial-resistance interpretation; water resistance is not used as proof of cybersecurity.
Known vulnerabilities	Very common	[2] 🔗 Proof	Android platform history contains multiple documented vulnerabilities. For example CVE-2024-43091 is a high-severity System RCE with Android 12-15 fixes in the November 2024 bulletin. Applicability requires the affected component and unpatched build; this is device-type/platform history, not proof this exact model is currently exploitable.
Prior attacks	None	[3] 🔗 Proof	No attack explicitly attributed to this exact product was identified in the limited manufacturer/Android, CISA and NVD search performed on 24 October 2026. None means no identified model-attributed report in that review, not proof of zero incidents. Android-class targeted exploitation (for example CVE-2024-43047) is background risk and is not assigned to this SKU without component/version evidence.
Updatability	Rare	[4] 🔗 Proof	ASUS provides model-specific firmware and security-patch notes, including the 2026-07-01 package with May 2026 patches. This establishes an active update mechanism, not a guarantee that every monthly patch is delivered immediately. Rare/2 is a conservative mapping for non-monthly delivery and the documented patch lag, not a claim that updates are unavailable.
Category Score	Score: 2 / 3

2. System Security

Criterion	Value	Proof	Comment
Authentication with other systems	Partial	[5] 🔗 Proof	Android supports server certificate validation and client-certificate authentication. Mutual authentication is chosen per service/application and is not universal; Partial reflects that documented configurable architecture.
Communications	Encrypted with up-to-date encryption	[6] 🔗 Proof	TLS 1.3 is supported and enabled for platform TLS connections. CRIS 1 applies to the stated validated TLS 1.2/1.3 application paths. Apps can enable plaintext traffic or weaken validation; all radio traffic and arbitrary apps are not claimed encrypted.
Storage	Encrypted with up-to-date encryption	[7] [8] 🔗 Proof	This model launched with Android 14 or later. Android requires file-based encryption for devices launching with Android 10+, and its compatibility rules specify modern encryption for private/shared data in internal storage. CRIS 1 is a platform-compliance inference for stock firmware, not a flash-dump test. Removable cards and all read-only partitions are outside the claim.
Category Score	Score: 2 / 3

3. User Authentication

Criterion	Value	Proof	Comment
Account management	Basic	[9] 🔗 Proof	Users can add/remove service accounts and manage local access settings. Basic assesses the personal single-owner profile; it does not treat multiple cloud sign-ins as full local administrator/least-privilege role management. Enterprise management is outside scope.
Authentication	Basic	[10] 🔗 Proof	Screen-lock credentials are configured in this assessment; biometric convenience options retain a backup credential. Basic maps ordinary configurable user authentication, not mandatory multi-factor authentication. Leaving the lock disabled would invalidate this profile.
Brute-force protection	Exist	[11] 🔗 Proof	Android Gatekeeper requires throttling of repeated failed credential checks in the protected authentication path. This documents a brute-force defense for the screen lock; exact vendor delay thresholds were not measured and online app-account rate limits are separate.
Event logging	Partial logging	[12] 🔗 Proof	Android maintains bounded diagnostic system/app logs. Complete enterprise screen-unlock auditing requires device-owner management; it is not assumed in this personal configuration. Partial logging does not imply a permanent tamper-proof access audit.
Passwords	Default/Common/Easy to guess	[13] 🔗 Proof	The personal Android policy allows user-chosen PIN/pattern/password and does not mandate periodic or post-setup replacement with enterprise complexity. CRIS 3 maps that permissive policy to the available options, not a claim of a shared factory password or a weak password on an observed unit.

Assessment scope

Individual documentation assessment, 24 October 2026; no physical testing or exploitation. Assessed configuration: authentic manufacturer Android firmware, locked bootloader, installed available security updates, a configured screen-lock credential and application traffic using correctly validated TLS 1.2/1.3. The communication score covers these TLS application paths, not all cellular signaling, SMS, arbitrary installed apps, Bluetooth profiles or optional plaintext services. Storage covers private/shared user data in internal flash, not an assertion that every read-only boot partition or removable card is encrypted. Platform requirements and manufacturer statements are distinguished from direct inspection. Controls may differ on rooted devices or custom firmware. The site has no Mixed or Unknown option: the stated boundaries are essential to interpreting this documentation rating.

Exact model and practical risk

ASUS Zenfone 11 Ultra is a connected Android smartphone; this review identifies AI2401_H specifically. ASUS maps Zenfone 11 Ultra to model number AI2401_H and model name AI2401. The ROG Phone 8 also uses AI2401 as a family name; the _H distinction and product name prevent that confusion.

Sensitive files and biometric enrollment depend on the lock credential and current firmware. Use the correct regional SKU when updating; firmware packages are not interchangeable.

Release-date evidence

2024-07-05 is the Japanese retail release date explicitly stated in ASUS JAPAN's manufacturer-authored press release of 2024-07-03. The March global announcement and preorder date are not substituted for regional retail availability.

Evidence interpretation

Known-vulnerability history uses the Android device type, as defined by WikiIoT. Prior-attacks None records only a limited search with no identified exact-model incident; it is not evidence of universal absence. Storage is an explicit inference from manufacturer OS identification and Android platform requirements. Product-specific hardware, model identity, release and update sources are provided separately. Optional enterprise subscriptions have not been assumed active.

Score calculation

CRIS vector: 2, 3, 1, 2, 2, 1, 1, 2, 2, 1, 2, 3. Category ceilings: [2, 2, 2]. Total 6; documentation-profile grade B. This is an assessor classification under the stated scope, not a vendor certification or instructor approval.

Practical improvements

Install offered security patches; retain official firmware and bootloader protection; use a strong unique lock credential and account MFA; reject invalid TLS certificates; restrict sensitive work to trusted apps; protect backups and removable media independently; review permissions and account activity.

Originality and limits

WikiIoT product-family searches on 24 October 2026 did not show this base product. Existing XCover7 Pro is a different model. Pending or unindexed pages may not appear in search. This is documentation research; no hardware or exploit test was performed.
