Numerous members of the cryptocurrency community have been hit by SIM swapping attacks over the past week, ZDNethas learned, in what appears to be a coordinated wave of attacks.
SIM swapping, also known as SIM jacking, is a type of ATO (account take over) attack during which a malicious threat actor uses various techniques (usually social engineering) to transfers a victim’s phone number to their own SIM card.
The purpose of this attack is so that hackers can reset passwords or receive 2FA verification codes and access protected accounts.
