Forensic Analysis of WhatsApp Takeover Vectors

Attack Methodology

Analysis confirms that sophisticated takeovers often begin at the network level rather than the application level. Attackers exploit SIM swap vulnerabilities to bypass control of the primary mobile number.

Key Findings:

• Unauthorized SIM deactivation at the MNO level.
• Bypassing 2FA by routing OTPs to attacker-controlled hardware.
• Maintaining control through rate-limiting weaponization.
