Security Evaluation

1. Device Security

Criterion	Value	Proof	Comment
Known hardware tampering	None	🔗 Proof	No publicly available method bypasses the Knox e-fuse hardware integrity check. Community research explicitly avoids triggering Knox.
Known vulnerabilities	Very common	[1]https://www.boannews.com/news/articleView.html?idxno=140230 🔗 Proof]	Multiple publicly disclosed severe vulnerabilities (e.g., ZDI-24-829 RCE; CVE-2025-21042 exploited in the wild by LANDFALL spyware).
Prior attacks	Very common	🔗 Proof	LANDFALL spyware utilized a zero-click WhatsApp DNG exploit targeting the S23 series (linked to "Stealth Falcon" infrastructure).
Updatability	Very common	🔗 Proof	Samsung promises 4 OS upgrades and 5 years of security updates (support until early 2028).
Category Score	Score: 2 / 3

2. System Security

Criterion	Value	Proof	Comment
Authentication with other systems	Full	🔗 Proof	Supports Samsung Account, Google Account, Passkeys, and standardized Knox enterprise authentication protocols.
Communications	Encrypted with up-to-date encryption	🔗 Proof	Supports TLS 1.3 and WPA3; Knox platform provides multi-layered hardware-to-app communication protection.
Storage	Encrypted with up-to-date encryption	[2]https://docs.samsungknox.com 🔗 Proof]	Uses Android File-Based Encryption (FBE) combined with Knox Vault hardware security (Common Criteria EAL4+ certified).
Category Score	Score: 1 / 3

3. User Authentication

Criterion	Value	Proof	Comment
Account management	Full	🔗 Proof	Full lifecycle management for Samsung Account (remote lock/wipe) and integration with Google and enterprise MDM/Knox.
Authentication	Secure	🔗 Proof	Offers under-display ultrasonic fingerprint and face recognition. Both require a PIN/password fallback.
Brute-force protection	Exist	🔗 Proof	Device-level password policies (configurable via Knox) can trigger a local wipe after a maximum number of failed attempts (recommended ≤ 10).
Event logging	Access event logged	🔗 Proof	Android native logcat auditing, plus Knox Audit Log for enterprise-level access, authentication, and policy change events.
Passwords	Require change after setup with complexity requirements	🔗 Proof	Knox management framework can enforce password complexity and periodic changes. (Note: If evaluating default out-of-the-box state, select "Require change after setup")
