Is Your Android Stale?
A stale Android phone is one that no longer receives security updates from its manufacturer or Google. Connect via WebUSB or select your device model to audit your patch posture, detect unpatched vulnerabilities, and enforce surgical hardening stopgaps.
Audit Your Device via USB
Audit your physical Android device in real time using client-side WebUSB. Zero drivers needed. Your phone's data stays 100% on your computer.
What is a “Stale Android”?
A Stale Android is any phone or tablet that has reached End-of-Life (EOL) and no longer receives security updates from its manufacturer or Google. Without monthly security patches, known vulnerabilities—including in-the-wild zero-days cataloged by CISA KEV—remain permanently unpatched on your device.
Stale Android inspects your device's firmware parameters, kernel release, and APEX update history directly in your browser via WebUSB or manual lookup, comparing them against official Android Security Bulletins to reveal unpatched vulnerabilities and generate actionable stopgap hardening commands.
100% Client-Side Privacy
Zero device identifiers, serial numbers, or IMEIs are transmitted across the network. All diagnostic matching and threat scoring execute locally in your browser memory.
CISA KEV Zero-Day Detection
Identifies unpatched vulnerabilities actively targeted in wild cyberattacks, flagging zero-click remote exploits and baseband vulnerabilities that require immediate stopgap defense.
Tailored Stopgap Hardening
Generates device-specific ADB shell commands and 1-click WebADB mitigations to neutralize attack surfaces (such as rogue 2G baseband downgrade and background radio tracking) without breaking normal operation.
Supported Device Manufacturers & Attack Vectors
Stopgaps and package mitigations are tailored to your specific phone architecture and detected installed packages.
