02Deep-Dive Technical Analysis
The threat actor called telecom carrier customer support, spoofed identity verification questions, and convinced the representative to reassign the SEC account administrator's phone number to an attacker-controlled SIM card. Because the SEC X account lacked multi-factor app-based authentication, the attacker initiated a password reset via SMS OTP, hijacked the account, and published a fake announcement.

04Recommended Defense & Mitigation Protocol

05Security Impact & Geopolitical Consequence
Resulted in the arrest of the perpetrator by the FBI and forced the FCC and major US carriers to mandate secure port-out PINs and biometric authentication for retail SIM changes.
