Fraudology Podcast with Karisse Hendrick

Welcome back to Fraudology.

Assaf Kipnis first joined me back in 2023, just after he left Facebook, for a two part conversation on how bad actors use social media platforms. Since then he has worked at Google and an AI startup, started his own consultancy, and spent most of his time building with AI. He now spends about 90% of his working day on AI builds, and that makes him the right person to ask a question I keep hearing from fraud leaders. How do we use AI without losing control of it?

We talk about AI...

Welcome back to Fraudology.

This is part two of my conversation with Mohammad Muzahir, also known as Red Bull, the cybercrime whistleblower in the WIRED reporting on scam compounds. In part one, Mohammad described how a fake job offer took him to a scam center in the Golden Triangle region of Laos, and how forced workers were handed scripts, personas, and stolen accounts. This time we pick up with what keeps people inside, how deepfakes make a persona believable, and how he finally got out. This conversation includes human trafficking, violence, and corruption, and Mohammad describes all...

This is a survivor’s story. Mohammad Muzahir, also known as Red Bull, is the cybercrime whistleblower in the WIRED reporting that opened a window into how scam compounds work. He escaped one, and he now spends much of his time helping large organizations understand how they operate.

He was studying computer science and looking for a way to fund a bachelor’s degree abroad when a friend of a friend offered him an IT manager job in Laos, in the Golden Triangle region. The job did not exist. What followed is a human trafficking story and a fr...

Welcome back to Fraudology.

I’m sharing the presentation I gave to open the Merchant Fraud Alliance conference in Chicago. It was a “where are we right now” look at the fraud attack landscape, and it grew out of a question I heard from merchants all through the conference. What is actually different about fraud today, and how much of it comes down to AI?

If you work in e-commerce fraud, you have probably felt the shift in your own numbers. Generative AI has changed who can attack, how quickly they can do it, and how we...

Welcome back to Fraudology.

I’ve now had a few days to recover from the inaugural Merchant Fraud Alliance conference in Chicago. I helped create this event. Watching two days of conversation among merchants go from a plan to a room full of people was a real highlight for me.

The Merchant Fraud Alliance 2026 conference was built around a gap I had heard about for years. Merchants wanted a place to compare notes with peers without feeling like the target of a sales pitch. We kept the ratio at roughly three merchants for every solution pr...

Welcome back to Fraudology.

Welcome back to Fraudology. I'm Karisse Hendrick, and this week I'm talking with someone who has become a regular guest on the show. Matt Vega has joined me across six years and several different employers. He's now the Chief Fraud Strategist at Point Predictive, where he works with Frank McKenna on lending fraud, and his move into that world gave me a good reason to ask what looks different from where he sits.

Lending fraud rarely looks like the fraud most merchants picture. Plenty of losses start with an applicant who...

Welcome back to Fraudology.

AI is here, and it’s making every kind of fraud we already know cheaper, faster, and harder to catch. We are going to walk through a handful of stories that show exactly how AI enabled fraud is showing up right now. From card testing at scale to one very messy fraud story.

That story is Polymarket, and I spend some real time on it. It’s rare that we get this much visibility into a company’s actual fraud details. A Wall Street Journal investigation lays out the stolen debit cards...

I'm joined today by Sudhir Lanka, Associate Director of Fraud Strategy at GrubHub. Sudhir's team doesn't just cover GrubHub anymore. His scope recently expanded to include Wonder, GrubHub's new parent company, and Blue Apron, which means he's thinking about food delivery fraud across three genuinely different business models at once, and I wanted to dig into how that actually changes his approach.

We get into what makes a three-sided marketplace uniquely exposed to fraud, since GrubHub has to protect diners, restaurants, and drivers all at the same time, and a gap in protection on any one side...

Welcome back to Fraudology.

This is a solo episode, and I’ve got two stories for you this week. I wanted to follow-up on the ID scan breach that Frank McKenna and I discussed last week. Where things stand now, whether we should still be worried, and what the driver’s license data breach means for KYC fraud prevention going forward.

And then I wanted to get into one of the biggest fraud stories this week. This one is brand new and I wanted to get it to you as soon as possible. A government emai...

Welcome back to Fraudology.

I’m joined this week by Frank McKenna of Frank on Fraud and Point Predictive, because this was one that I needed a second brain to process it all with me.

I was heads-down working on the Merchant Fraud Alliance agenda when my phone would not stop buzzing. It was a group chat with the people I trust to tell me when the big deals are happening versus just internet noise. And this time, it was a big deal. Brian Krebs had uncovered a dark web portal selling real driver’s lice...

Welcome back to Fraudology.

It’s just me for this episode, but I’ve got two stories to dig into. They are genuinely important for anyone dealing with chargeback disputes. Whether you’re on the merchant side or the banking side.

The first is Uber and the nearly billion dollars in fines for automated account deactivation. The second story is the story that I really want to unpack. Hims and Hers blowing past their chargeback threshold on their weight loss subscription business.

It’s rare that this stuff becomes public, and I think there’s...

Welcome back to Fraudology.

Since I’ve been back from SardineCon, I’ve thought about how much faster and cheaper AI is making fraud. That thread runs through basically everything I’m covering today. I’m digging into a new report from Inscribe showing a 4X increase in AI generated documents. I’ll walk through the difference between a document that’s built entirely by AI and one that’s a real document with AI alterations. Because they are not the same problem.

Then we will go deep on a digital arrest scam, and this is the one I r...

Welcome back to Fraudology.

I have to tell you I’m genuinely excited about this one. Today’s guest was highly recommended by Matt Vega, someone whose opinion I trust completely in this industry. By the time we finally hit record, we’d already been talking for 45 minutes off air. That’s a pretty good sign this episode is going to deliver.

Cy Khormaee spent years at Google, building out what eventually became the company’s user protection platform and the technology that now runs quietly in the background protecting billions of devices worldwide from phishing a...

Welcome back to Fraudology.

Today's a solo episode built around a study that puts a real number on something fraud leaders have been debating for years: does organizational convergence for fraud actually move the needle on performance, or is it just an org chart trend?

For years, we've all benchmarked ourselves the same way. Approval rate here, chargeback rate there, maybe a manual review rate if we're being thorough. But the problem I've seen play out in company after company is this: optimize your approval rate, and your chargeback rate quietly creeps up. Optimize your...

Welcome back to Fraudology.

This week I’m joined by Dave G., who spent years investigating money laundering, wire fraud, and scams before moving into e-commerce and, eventually, directly into crypto. Dave was on the ground floor of Bitcoin back when the white paper first came out, and he brings a rare vantage point on stablecoin fraud risk as someone who has watched a payment technology evolve from a niche curiosity into the backbone of a real conversation about agentic commerce.

We start with a story that sets the tone for the whole conversation. It de...

In this episode, I'm sitting down with Tal Yeshanov. Someone I've known for a very long time in this industry, and one of the sharpest risk leaders I know. Tal's path into fraud started almost by accident at Google and YouTube. Then took her through building fraud programs at Eventbrite, before its IPO, and Uber during its earliest hockey-stick growth years. Tal has spent her career building holistic fraud detection systems from scratch, in industries where there was no playbook to follow.

For years, fraud teams operated off a snapshot. Device at checkout. IP at checkout. Did...

Welcome back to Fraudology.

Every once in a while I come across a report that makes me stop what I was planning to talk about because it's just that important. This is one of those weeks.

Matt Vega recently released his quarterly fraud report 2026, and after reading it, I knew we needed to break it down together. Not because it's predicting what might happen next year. Because every attack covered in this report is already happening.

One of the biggest themes running through the report is that fraud is simply moving faster than...

Welcome back to Fraudology.

In this episode, I’m sitting down with Mark Porteous, a longtime leader in e-commerce fraud and trust who knows two-sided marketplaces from the inside out. Mark spent nine years at StockX, where he started in customer support before building the company’s fraud program from the ground up. And honestly, that is one of the best ways to learn marketplace fraud prevention because you see the customer complaints, the chargebacks, the seller issues, the account problems, and the policy gaps before anybody has officially decided they belong to a fraud team.

We...
