Executive Summary
FlexiSPY is one of the most notorious commercial spyware platforms, marketed as a parental monitoring tool but widely abused for illegal surveillance, stalking, and corporate espionage. Available for Android, iOS, Windows, and macOS, it provides attackers with root-level control over devices, allowing theft of calls, chats, keystrokes, and even camera/microphone access.
CyberDudeBivash confirms:
- FlexiSPY is classified as dual-use spyware: legitimate claims, malicious abuse in practice.
- Threat actors deploy it via phishing, sideloading, and physical device compromise.
- It has stealth persistence, bypasses basic AV, and exfiltrates data to remote C2 servers.
- Target victims include journalists, executives, activists, and high-value individuals.
