Unauthorized Instagram access typically exploits social engineering (phishing, credential stuffing), SIM-swap intrusions, and session hijacking via unsecured networks. Such breaches risk data exfiltration, identity theft, and non-compliance with GDPR/CCPA. To enhance resilience, implement multi-factor authentication (preferably via TOTP apps), enforce unique strong passwords through a password manager, routinely audit active sessions, and restrict logins by device or IP. For proactive device monitoring and activity alerts, consider mSpy.
