What is SIM Swap Fraud?

SIM Swap Fraud, simply put, involves changing mobile SIM cards without your knowledge, often for fraudulent activities. In this scam, fraudsters get a new SIM card issued against your registered mobile number through your mobile service provider. 

Once they have this new SIM card, they gain access to critical alerts, such as One Time Passwords (OTPs) needed to carry out financial transactions through your bank account. SIM Swap fraud is a type of identity theft, also known as "sim jacking" or "sim card hacking," which is usually the result of successful phishing of your personal details.

SIM Swap Fraud Example (Real-Life)

The case of cryptocurrency investor Michael Terpin is a prime example. He was a victim of a SIM swap scam where fraudsters convinced Terpin's mobile carrier to transfer his phone number to a new SIM card, which they controlled. Once they gained control, they accessed his cryptocurrency accounts, resulting in a staggering loss of $24 million. 

How is SIM Swap Fraud Carried Out?

Here are the steps involved in a SIM Swap scam:

Step 1: Information Gathering

Scammers collect personal information about their target victims. This information can be obtained through various means, including phishing emails, malware, social engineering, buying information on the dark web, or researching the victim's social media profiles.

Step 2: Impersonation

The scammers pretend to be the victim and contact their mobile carrier, claiming that their SIM card was lost or damaged. 

Step 3: Providing Personal Information

To pass security checks and gain the carrier's trust, scammers provide personal information collected about the victim to authenticate their identity.

Step 4: Activating a New SIM Card

The scammers convince the mobile carrier to activate their SIM card, replacing the victim's.

Step 5: Intercepting Communication

The scammers can now intercept texts, calls, and any other communication for the victim. This enables them to capture crucial security codes or password reset requests sent to the victim's phone.

How Can You Protect Yourself from SIM Swap Scams? (SIM Swap Fraud Prevention)

• Online Behavior: Be vigilant about phishing emails and other tactics attackers use to gather personal data. Avoid clicking on suspicious links in emails, especially from unknown senders.
• Account Security: Enhance your cellphone account security with a unique, strong password and security questions known only to you.
• PIN Codes: If available, set a separate passcode or PIN for your phone carrier account for additional security.
• IDs and Authentication: Avoid relying solely on your phone number for identity authentication. Use authentication apps like Google Authenticator, which tie to your physical device instead of your phone number.
• Bank and Mobile Carrier Alerts: Check if your bank and mobile carrier can collaborate on sharing information about SIM swap activity and implement user alerts for additional security checks when SIM cards are reissued.
• Behavioural Analysis Technology: Banks can employ technology that analyzes customer behaviour to detect compromised devices and avoid sending SMS passwords.
• Call-backs: Some organizations use call-backs to verify customer identity, which is especially useful in preventing SIM Swap Fraud.

How Can You Recognize Signs of SIM Swap Fraud?

1. Inability to Make Calls or Send Texts: Experiencing errors when sending texts or making calls can be an early sign of SIM Swap Fraud. This could indicate that your SIM card has been deactivated and fraudsters are now using your number.
2. Notifications of Activity Elsewhere: If your phone provider alerts you that your SIM card or phone number has been activated on another device, it's a clear sign of a SIM Swap.
3. Inability to Access Accounts: Finding your login credentials for accounts like banks or credit cards no longer working suggests scammers might have changed your passwords after taking over your phone number.
4. Unfamiliar Transactions: Noticing transactions you don't recall on your credit card statement could indicate that criminals have accessed your credit card information through your compromised phone number.

What Should You Do If You Fall Victim to SIM Swap Fraud?

If you fall victim to a SIM Swap:

1. Contact Your Provider: Immediately inform your mobile carrier of the suspicious activity and block the scammer's access.
2. Inform Financial Institutions: Alert your banks and credit card companies to secure your accounts against unauthorized transactions.
3. Change Passwords and Security Settings: Update all important accounts' passwords and security settings.
4. Legal Action: Consider legal action and report the incident to law enforcement agencies.
5. Monitor Your Accounts: Closely monitor all your financial and personal accounts for unusual activities.

How Can Social Media Influence SIM Swap Fraud?

Scammers often resort to social media to obtain personal information that they can use to impersonate victims in SIM swap scams. For instance, information such as your mother's maiden name or high school mascot - which are commonly used as security questions - can be easily found on your Facebook profile. 

Therefore, it's crucial to be mindful of the type of information you upload and the level of access you grant to others. Always double-check your privacy settings to ensure you're not publicly available sensitive information.
