The Rising Threat of SIM Swapping Attacks
SIM swapping, also known as SIM hijacking, is a type of account takeover fraud that enables hackers to gain access to your smartphone and the sensitive personal data it contains. By exploiting weaknesses in two-factor authentication and social engineering phone carrier employees, SIM swappers can essentially take over your phone number and intercept everything tied to it.
What is SIM Swapping?
SIM swapping refers to fraudsters contacting your mobile carrier and convincing them to transfer your phone number over to a SIM card they control. This grants them full access to any calls, texts, emails and app accounts associated with that number.
Once the SIM swap is completed, all inbounds calls and messages will be routed to whatever phone the hackers inserted your SIM card into. They then leverage this to bypass two-factor authentication and reset the passwords to your email, social media, financial accounts and more.
Why is SIM Swapping So Dangerous?
SIM swapping exposes victims to wide range of threats and account breaches, including:
Email/social media account takeovers - With access to victim’s texts and calls, hackers can trigger password resets and intercept confirmation codes.
Financial theft - Retirement accounts, cryptocurrency wallets and bank accounts could all be drained once SIM swappers gain entry.
Identity fraud - Personal info tied to the phone number can be leveraged to open new fraudulent accounts.
Sensitive data theft - Photos, messages, contacts and other private data are exposed.
Home break-ins - Your phone can be used to disable smart home alarms and security cameras.

Who Conducts SIM Swap Attacks?
Most SIM swappers are organized cybercriminals seeking big payouts, especially from cryptocurrency theft due to lax identity verification at many exchanges. They often recruit telecom industry employees to assist with number porting or sell the ported numbers on dark web markets. Individual hackers may also perform smaller one-off SIM swaps.
How to Protect Yourself from SIM Swapping
Here are some tips to safeguard against having your number swapped:

3. Set up account alerts to detect unauthorized logins or password changes.
4. Limit sharing of your phone number online and enable call/text filtering if possible.
5. Utilize privacy services like that shield your phone number to deter number porting.
