  • The fraud can expose text-message authentication and account-recovery messages, creating serious privacy risks.
  • Criminals first collect personal information, then impersonate the victim to the mobile operator or access the customer account.

“You suddenly lose network coverage? Be careful: a hacker may have stolen your digital life.” That warning from the Somme gendarmerie captures the danger of SIM swapping, a scam that takes control of a person’s phone line through a virtual SIM card.

In a Facebook post dated August 27, the gendarmerie said several residents of the French department had fallen victim to the practice. The attack can expose SMS authentication codes and messages used to recover online accounts, with serious consequences for privacy.

Criminals first gather identity details such as a person’s name, date of birth, email address or postal address. They then pose as the victim to the mobile operator or break into the customer account, which is often protected only by a password and no two-factor authentication.

According to Bouygues Telecom, the fraud first appeared in France as early as 2012.
