  • •Pegasus spyware uses zero-click exploits to infect devices without user interaction.
  • •It can access messages, calls, and activate cameras/microphones undetected.
  • •Standard antivirus solutions cannot detect Pegasus; forensic checks are necessary.

Pegasus spyware, developed by NSO Group, infects mobile devices through zero-click exploits, allowing it to silently harvest messages, calls, and location data. It can activate cameras and microphones without user knowledge. The spyware is known to target both iOS and Android operating systems, exploiting vulnerabilities that are often unknown to manufacturers. While initially marketed for law enforcement, Pegasus has been misused to spy on journalists and activists. Standard antivirus tools fail to detect it, requiring forensic checks for confirmation of infection. High-risk users are advised to use Apple’s Lockdown Mode and maintain cautious app and network habits. The rise of Pegasus highlights critical vulnerabilities in mobile security, even among trusted systems.
