SIM SWAP Scams are Rising, Know-How not to become a Victim

The number of SIM swap cases has risen to three times in the last five cases. In 2015, people only reported 144 cases in the UK. At present, there are more than 483 cases all around the UK. It's not just the UK where people are losing their bank accounts due to SIM Splitting, other two noteworthy countries where people reported these scams are India and Nigeria.

Criminals swap SIM to get full control over the bank and other accounts of a person with two authentication factors or code. They get access to accounts, change their personal details, and start exploiting it.

As more and more cases are reported, getting an idea of what SIM SWAP is and how not to become a victim is essential knowledge.


It is also known as SIM Splitting, SIM Swapping, SIM Jacking, Port Out Scam, and Smishing. Two-factor authentication is regarded as one of the most effective security measures for your online accounts on social media and banks. According to this method, a person doesn't only add a password but also provides (One-Time-Password/ OTP) to make a transaction or login to his account.

He gets OTP on his phone number via text or phone call. Criminals have found a way to circumvent this most robust security measure through SIM smishing. They SWAP your SIM by making the phone company think that you have lost your phone, and you need this SWAP on your new mobile.

Losing a phone and swapping SIM to a new phone is a common thing. For this swap, a person needs to share his personal details like name, birth date, maiden name, secret question answer, etc.

These days, getting access to these personal details is not difficult. Criminals get access to these details in the following ways:

  • bribe the phone company's employee and access the personal data of anyone.
  • stalk their target on social media where people share it all
  • do data mining online by hacking the company's security system

Once criminals get all the details, they call the phone company and pretend to be the victim. When a company asks for personal details, they provide it and pass a security check. Next, they request a SIM Swap and change all personal information.

An Incident That Leads to SIM SWAP Awareness

People didn't know hackers hijacked much about SIM Splitting fraud until Jack Dorsey's Twitter account. Jack Dorsey is the Chief executive officer of Twitter, and his SIM swapping created a buzz on social media. The criminal held his account for 30 minutes and posted tweets of profanity, Adolf Hitler, and a racial slur.

Dorsey wasn't the only victim; some weeks later, another incident was reported. Jack Monroe, the food writer, and campaigner lost 5000 pounds from his bank and payment accounts, which were accessed through the hijacker's phone.

After investigation, it was clear that Dorsey and Monroe were the victims of SIM SWAP fraud. Action Fraud has shared some statistical data that explain that SIM Smishing incidents have been rising since the last five years. Thousands of people have lost their accounts, and this scam has made UK residents lost 10 million pounds all those years.

Security measures for phones and financial accounts have changed a lot over all those years, but the rate of fraud remained consistent throughout this time. Some cases were nothing but an inside job where Telephone company's employees leak data to criminals for money. In contrast, other SIM Swap scam cases were all about those criminals who knew all about the right mixture of confidence tricks and online stalking.

The latest method of SIMjacking is one where criminals request PAC (porting authorization code). Through this code, they quickly port the victim's number to a new network. Once they own the victim's number, it's time to intercept bank authorization sent through SMS or other codes to the same number on different networks.
