SIM swap attacks involve criminals transferring a victim's phone number to a SIM card they control, allowing access to sensitive accounts. In 2024, the FBI recorded 982 SIM swap complaints. Despite FCC rules from November 2023 aimed at preventing such attacks, compliance has not yet been enforced as of mid-October 2026. Criminals typically use social engineering, insider threats, or phishing to execute these attacks. Victims are primarily crypto holders, as mobile numbers are crucial for two-factor authentication in financial transactions. The FBI's February 2022 alert highlighted the increasing trend of these attacks, which can lead to significant financial losses. The number of complaints reported by the IC3 fell by 51.53% from 2022 to 2024, indicating some decline in incidents, but the threat remains significant.
