Why Keyra Uses RASP Technology to Protect Your Assets

Introduction

Your mobile phone is a powerful computer—but it’s also a computer you take everywhere, install random apps on, and connect to public WiFi. For a cryptocurrency wallet, this creates unique security challenges.

Traditional security measures like encryption protect your data at rest. But what happens when a sophisticated attacker modifies your device’s operating system or injects code into your running app?

That’s where RASP comes in.

What Is RASP?

RASP stands for Runtime Application Self-Protection. Unlike perimeter security (firewalls, VPNs) or static analysis, RASP operates inside your application, monitoring every execution in real-time.

Think of it like this:

RASP technology is used by major financial institutions, banking apps, and now—Keyra.

The Threats RASP Protects Against

1. Rooting and Jailbreaking

When a device is rooted (Android) or jailbroken (iOS), the operating system’s security model is compromised:

• Other apps can access protected data
• Malware can run with elevated privileges
• Screen overlays can capture your input
• Memory can be read by malicious processes

Keyra’s response: Detects rooted/jailbroken devices and alerts users to the elevated risk. Critical security features may be disabled on compromised devices.

2. Debugging Attacks

Debuggers allow attackers to:

• Pause your app’s execution
• Inspect memory for private keys
• Modify values in real-time
• Bypass authentication checks

Keyra’s response: Detects attached debuggers and terminates sensitive operations immediately.

3. App Tampering

Modified versions of apps (repackaged APKs) might:

• Remove security checks
• Include keyloggers
• Send data to attackers
• Display fake interfaces

Keyra’s response: Verifies app integrity at runtime. If tampering is detected, the app refuses to operate with cryptographic functions.

4. Overlay Attacks

Malicious apps can draw invisible overlays on top of your wallet:

• Fake “Confirm” buttons that redirect transactions
• Phishing screens that capture seed phrases
• Invisible input fields stealing passwords

Keyra’s response: Detects screen overlay attacks and pauses sensitive operations until overlays are removed.

5. Emulator Detection

Attackers use emulators to:

• Analyze app behavior in controlled environments
• Automate credential theft at scale
• Test attack vectors without real devices

Keyra’s response: Detects emulator environments and restricts functionality.

How RASP Works in Keyra

Keyra’s RASP implementation operates on multiple layers:

┌─────────────────────────────────────────┐

│  ┌─────────────────────────────────────┐ │
│  │         RASP Security Agent          │ │

The Decision Engine

When a threat is detected, Keyra’s RASP engine makes real-time decisions:

The Automatic Key Wipe

The most powerful response in Keyra’s arsenal is the automatic key wipe. When multiple critical indicators suggest an active attack:

1. All private keys are immediately cleared from memory
2. Encrypted key storage is locked
3. User is notified of the security event
4. Recovery requires re-authentication

This means even if an attacker gains code execution, they find… nothing. The keys are already gone.

Why Other Wallets Don’t Have RASP

RASP integration is complex and expensive:

• Requires deep platform expertise (both iOS and Android)
• Increases app size and startup time
• Needs constant updates as attack vectors evolve
• Many wallet teams prioritize features over security

At Keyra, we believe security is the feature. You can’t enjoy DeFi gains if your wallet gets drained.
