SIM swapping is a highly technical illegal attack used to steal high pokemon card price assets. Hackers legally trick your mobile carrier into porting your phone number to a SIM card they control. They then use your number to reset the passwords on your email, which they use to access your eBay or TCGPlayer accounts, legally stealing your pokemon card price inventory. Legally, setting up a PIN with your mobile carrier is the best defense against this.
These bad actors then dump the cards on underground forums at a heavily discounted rate to quickly convert the stolen goods into untraceable cryptocurrency.
