Black Friday is right around the corner and while bargain hunters are preparing to find the best deals, fraudsters are making plans to prey on unsuspecting consumers. If your company uses multi-factor authentication (MFA) such as one-time SMS passwords (OTPs) to safeguard customer accounts, you might think you’re covered. But our recently published analysis of over 385,000 retroactive SMS & Voice OTP transactions, conducted using our Trust Score™ technology, unearthed 4 concerning multi-factor authentication vulnerabilities:
- FinTech and e-Commerce/Retail may be particularly at risk. The analysis shows 2X and 18X higher chances, respectively, for low Trust Score transactions in these sectors.
- 2.5% of mobile MFA transactions were found to have low Trust Scores
- 5% of mobile transactions had low SIM tenure, indicating potentially fraudulent SIM swaps
- 10% of multi-factor authentication transactions were over Non-Fixed VoIP (voice over internet protocol, i.e. virtual phone numbers not tied to a physical address) lines. This increase in non-mobile device types is concerning because it indicates a potential opportunity for bad actors.

The analysis indicates possible vulnerabilities in companies’ current multi-factor authentication processes, which may be unknown to the companies themselves. These results point to both major information deficits, such as outdated customer information, as well as risks that are not being addressed by in-place security measures, leaving companies and customers vulnerable to bad actors. The study also shows that these multi-factor authentication concerns can be addressed by fortifying one-time passwords with a trust indicator such as Prove’s Trust Score, which uses behavioral and phone intelligence signals to measure fraud risk and identity confidence.
