In this episode of Fraudology In this eye-opening episode of the Fraudology Podcast, host Karisse Hendrick uncovers two shocking case studies that expose major security failures at T-Mobile and Meta, and what they mean for the future of digital fraud prevention.

Karisse begins by breaking down the rocky rollout of Visa’s new risk-monitoring system, VAMP, explaining why it’s causing confusion and frustration for eCommerce merchants and acquirers. She also shares exciting news about co-founding the Merchant Fraud Alliance, a first-of-its-kind conference designed to bring together top online merchants for meaningful collaboration—without the vendor noise.

The episode’s main focus dives into two alarming corporate case studies:

• T-Mobile’s 20-Year SIM Swap Problem: Karisse examines legal documents proving that T-Mobile has known about SIM swap vulnerabilities since 2005 but failed to take action—allowing cybercriminals to steal millions in cryptocurrency through unauthorized SIM swaps.
• Meta’s WhatsApp Whistleblower Scandal: A former security chief alleges that up to 500,000 WhatsApp accounts were hacked every day, and over 1,500 engineers had unrestricted access to users’ private data—while Meta leadership ignored the warnings and retaliated against him.

These stories reveal how even the world’s largest tech companies have chosen growth over security, offering critical lessons for anyone responsible for protecting users, data, or digital payments.

Whether you’re a fraud prevention expert, eCommerce leader, or cybersecurity professional, this episode will give you actionable insights into today’s most pressing digital threats—and how to stay ahead of them.
