SIM swapping is a known issue, so if they find evidence of it, they’ll probably know what to do. Find a connection as soon as possible and get in touch with your carrier.If your phone suddenly loses service in a place where you normally have it, you may want to consider checking with your carrier. Even something as seemingly innocuous as a memorable Instagram handle, like could prompt a hack, since these can sell for surprisingly large amounts of money. People with easily accessible personal information, high-profile social media accounts, or high-value financial accounts are certainly vulnerable, but that doesn’t exclude average people with a decent sense of online security from running into this issue. Pretty much everyone is at risk of getting their SIM hijacked, but since it’s not the simplest attack to carry out, only so many people can be targeted at a time. This will go on until they’ve gotten what they want or until the user gets their access revoked. If the hacked account is a bank, cryptocurrency exchange, or other financial institution, they’ll take money. Once in, attackers will generally change passwords, email addresses, and other information that could enable users to regain control of their accounts. With your phone number, they often only need to know your email address and possibly a few pieces of personal information to get in. Once the number is under the attacker’s control, they can use it to gain access to accounts by using its 2FA capabilities or using it to reset your passwords.
