SIM Swap Fraud is Preventable – Why Aren’t More Companies Doing Something About It?

A different way of looking at SIM swap fraud

The focus of the Princeton study, Senator Wyden’s letter, and really most of what has been written on the internet about SIM swap fraud has been the role that mobile carriers play in attackers carrying out fraud. As evidenced in these writeups, the step where hackers dupe customer service agents into swapping their SIMs is vital to the attack being successful. But it’s also very difficult to prevent because it involves humans, and specifically customer service agents, who are trained to be as helpful as possible. But upon further inspection, this step is not where the actual damage is done.

In most cases, the actual damage – theft of funds, hijacking of a social media account, or theft of cryptocurrency – occurs after the fraudster actually goes to log into the victim’s accounts using the phone number he has just taken over. So technically, just taking over your phone number is not enough. In order to really inflict damage, a fraudster also needs to log into your accounts.

An opportunity to stop SIM swap fraud in its tracks

This is where Prove’s patented Phone Intelligence comes into play. When the fraudster goes to log into the victim’s account, the business (whether it be a bank, crypto platform, social media platform, or other kind of enterprise) can use Phone Intelligence to detect that a SIM swap has taken place and block the fraudster from taking nefarious actions.

Consider this scenario involving a cryptocurrency exchange:

1) Fraudster steals username/password of victim and logs into cryptocurrency exchange.
2) Fraudster takes over victim’s phone number through a SIM swap attack.
3) With Payfone enabled, the cryptocurrency exchange can call our APIs to see if a SIM swap has occurred on that account.
4) If a SIM swap has occurred, the cryptocurrency exchange routes the user to further inspection before granting them access to the account.
5) Because accounts can be locked before any damage can be done, the cryptocurrency exchange is able to shut down hackers before they can do harm, safeguarding their users’ cryptocurrency.

Why CX and digital executives should also take note

From a customer experience standpoint, Phone Intelligence has the additional benefit of creating a more seamless experience for legitimate users. Since many SIM swaps are legitimate (in 2018, there were 90 million ports and 100 million device upgrades in the U.S.), simply detecting SIM swaps and hitting anyone who has swapped their SIM with a ton of friction can be significantly damaging to your customers’ experience and, in turn, customer satisfaction. Enterprises must be careful not to slow down the experience for customers who may have legitimately ported their numbers or upgraded their devices. By analyzing the contextual behavior and time of a SIM swap, Payfone provides a more sophisticated and nuanced approach to thwarting SIM swap fraud. As a result, you can offer a faster and easier experience for good customers while identifying potential bad actors and subjecting them to further inspection.

It’s also important to note that customers of businesses who do not use Payfone have to jump through considerable hoops if they want to go the DIY route to protect themselves against SIM swap fraud. There are numerous articles that give recommendations on how to do this (calling your mobile carrier, setting up a pincode, then setting up a longer 16-digit pincode, etc.) but not only is this time-consuming, these precautions are totally ineffective when hackers break directly into telecom companies to swap SIMs.

The Bottom Line: Implementing technology that not only safeguards your customers against SIM swap attacks but also betters their experience is an investment. However, it’s an investment that can not only help you avoid losing customers, but also to attract new customers by differentiating your company as one that cares about their security, convenience, and experience.

What’s a Rich Text element?

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

Static and dynamic content editing

A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!

How to customize formatting for each rich text

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
