Pegasus spyware represents one of the most sophisticated and dangerous mobile threats ever created. This invisible surveillance software, developed by the Israeli company NSO Group, has been used to target journalists, activists, politicians, and business leaders worldwide. Understanding how Pegasus works and how to protect against it is crucial for anyone concerned about mobile security and privacy.
What is Pegasus Spyware?
Pegasus is a sophisticated spyware tool that can be installed on mobile devices (both iOS and Android) to provide complete surveillance capabilities. Once installed, it operates invisibly in the background, giving attackers unprecedented access to the target's digital life.
Key Capabilities:
- Complete Device Control: Access to calls, messages, emails, and social media
- Real-time Surveillance: Live camera and microphone activation
- Location Tracking: GPS monitoring and movement history
- Data Exfiltration: Stealing photos, documents, and sensitive information
- Zero-Click Installation: Can infect devices without user interaction
- Persistence: Survives device restarts and software updates
How Pegasus Infects Devices
1. Zero-Click Exploits
The most sophisticated attack vector, zero-click exploits require no user interaction. Pegasus can infect devices through:
- iMessage Exploits: Malicious messages that execute code automatically
- WhatsApp Vulnerabilities: Exploiting messaging app security flaws
- Email Attachments: Malicious documents that execute when opened
- Network Injection: Intercepting and modifying network traffic
2. Social Engineering Attacks
When zero-click exploits aren't available, attackers use sophisticated social engineering:
- Phishing Messages: Convincing users to click malicious links
- Fake Updates: Impersonating legitimate software updates
- Compromised Apps: Malicious applications in app stores
- SIM Swapping: Taking control of phone numbers to bypass 2FA
3. Physical Access
In some cases, attackers gain physical access to devices:
- Direct Installation: Installing spyware during device "maintenance"
- Supply Chain Attacks: Compromising devices before delivery
- Social Engineering: Tricking users into installing "security" apps
