SIMvahetus

SIMvahetus, also known as SIM card swapping, is a practice where a subscriber's SIM card is replaced with another, often without the subscriber's knowledge or consent. This can occur through various means, including theft, hacking, or social engineering. SIMvahetus can lead to unauthorized access to the victim's mobile services, including voice calls, text messages, and internet data. It can also result in financial losses, as the new subscriber may incur charges on the victim's account.

The process of SIMvahetus typically involves obtaining the victim's personal information, such as their name, address, and phone number, which can be gathered through phishing attacks, social media, or other means. Once the information is obtained, the attacker can request a new SIM card from the mobile network provider, using the victim's details. The new SIM card is then activated and used to access the victim's services.

To protect against SIMvahetus, mobile network providers have implemented various security measures, such as two-factor authentication and SIM card locking. Users can also take steps to protect their personal information and be vigilant about suspicious activity on their accounts. If a SIMvahetus is suspected, users should contact their mobile network provider immediately to report the incident and request a new SIM card.
