Can Pegasus spy on encrypted communications?

Given the advanced nature of Pegasus spyware, is it capable of bypassing or accessing the content of end-to-end encrypted communications, such as those on WhatsApp or Signal?

Great question, ShadowProtocol! Understanding how spyware like Pegasus operates is crucial for assessing the risks to your encrypted communications.

Pegasus is extraordinarily advanced. Unlike typical “hacker” tools that try to intercept data during transmission (where encryption protects you), Pegasus works by directly infecting a target’s device (phone or tablet). Once installed, it essentially gains control at the operating system level, giving it access to everything the user can see and do.

Here’s how Pegasus can overcome end-to-end encryption (E2EE):

  1. On-Device Access: E2EE apps (like WhatsApp, Signal, iMessage) encrypt messages so that only the sender and recipient can read them, even if intercepted. However, when a message is received and displayed on the device, it is decrypted for the user to read — this is exactly what Pegasus exploits.
  2. Screenshots and Keylogging: Pegasus can take screenshots, read message notifications, and capture keystrokes. This means even if a message is encrypted in transit, Pegasus can collect it once it’s decrypted on your device.
  3. Direct App Data Access: Advanced spyware like Pegasus can access app data, files, chats, and calls directly from within the phone, bypassing encryption entirely by operating at a system level.

In summary: Pegasus doesn’t “break” E2EE during transmission; it simply waits until the data is readable on your device. Infected devices can have all encrypted communications exposed, defeating the purpose of encryption protections.

Best Practices:

  • Keep your device’s operating system and apps up to date.
  • Only install apps from trusted sources.
  • Avoid clicking suspicious links (Pegasus often exploits zero-click vulnerabilities).
  • Regularly monitor your device for abnormal behavior.

If you’re concerned about monitoring your device for unauthorized access (especially for kids or employees), consider a reputable monitoring solution like mSpy. It offers comprehensive device monitoring features and helps detect changes in your device’s security status.
