A few weeks ago, I talked with law enforcement and prosecutors at IAFCI's Fraud Unplugged in Nashville. The clearest thread running through almost every conversation was that fraud is getting easier to commit, and documents are at the center of it. A fake ID, a forged pay stub, or a doctored bank statement can be enough to get past a person or a system when it looks real enough.
Behind these schemes are real people and businesses dealing with the consequences, whether that's someone whose identity was stolen, a financial institution absorbing a loss, or a legitimate customer whose application gets caught up in the fallout.
Here's what I learned about how these operations actually run.
One investigator told me that mail fraud is more profitable than drug trafficking for some criminal groups, with less risk. Sentences are shorter, and enforcement is thinner, which makes it an attractive option for some groups.
One example from the conference involved a Chicago gang that reportedly made $100 million in a single year using stolen identities and checks. I can't confirm that this was the same case, but the broader pattern is well documented publicly. The U.S. Postal Inspection Service and USPS Office of Inspector General uncovered a Chicago mail theft ring that recruited 35 postal employees across more than 200 zip codes, stealing checks, credit cards, and personal information from more than 10,300 victims, with criminal cells operating in four other states. That case ended in federal prison sentences and $6 million in restitution.
Researchers tracking stolen-check marketplaces have also found that proceeds from check fraud increasingly fund other criminal activity, including drugs and guns.
Mail theft isn't limited to checks, either. Bank statements and tax documents move through the mail constantly, and pay stubs are one of the specific items thieves target when they redirect someone's mail. These documents contain exactly the personal details fraudsters need, and once they're stolen, they can become the raw material for fraudulent credit applications, forged IDs, and fabricated account paperwork.
Investigators described a scheme called "Operation Homeless," where fraud rings recruit unhoused people to help cash counterfeit checks at banks. The name isn't just a label used at the conference. The U.S. Department of Justice has used "Operation Homeless" to describe several related fraud schemes in which criminals recruited unhoused people to cash counterfeit payroll checks. In one case, investigators found that more than 75 unhoused people were recruited and used their own identification to cash the checks. The Department of Justice documented the case here.
The pattern has continued in other parts of the country. In a Utah case, for example, conspirators targeted people at homeless shelters who had government-issued identification, gave them counterfeit checks made out in their names, and bought them new clothes so they would not appear to be homeless when they went into banks. The Department of Justice documented that case here. Similar schemes have been prosecuted in St. Louis, Iowa, and Rhode Island, where recruiters offered cash in exchange for helping pass counterfeit checks.
There are also documented cases where fraudsters took the use of someone else's identity a step further. In an identity theft and account takeover investigation, the FBI found that a fraud ring exploited unhoused people as couriers and created fake IDs using the couriers' photos along with stolen personal information from other victims. The FBI documented the case here.
The details vary from one operation to another, but the impact is real for the people and businesses on the other side of these transactions. Fraudsters are finding ways to use other people, their identities, and their documents to make fraudulent transactions look legitimate, and those documents can be what allows the fraud to move forward.
Investigators described a person running a fraud operation from prison using an Android phone. The operation involved creating fake documents for people applying for credit products, along with credit washing, which is the removal of legitimate negative credit data from a consumer's credit report. TransUnion recently flagged credit washing as a fast-growing problem, estimating that $10 billion in debt was suppressed from credit reports in 2025 alone.
I couldn't find that specific case publicly, but contraband cell phones have enabled a documented pattern of inmate-run fraud across the country. In Georgia, federal prosecutors indicted 51 people, including current and former correctional officers, in a scheme run out of a state prison. In a separate Georgia case, an inmate orchestrated an $11 million fraud from inside a maximum-security unit. In another case, an inmate used only a prison phone to submit credit applications, purchase orders, and forged sales contracts, walking away with more than $2.8 million in stolen construction equipment before dealers caught on.
What stood out to me was how little infrastructure these operations required. A phone and a way to communicate can be enough to keep an operation moving when the person behind it can produce a document that looks legitimate. That makes the job of the people reviewing those documents even more important, because a fraudulent document that gets through can ultimately mean a real financial loss for a business or a real person.
The thing I keep coming back to is how little it takes to run a real fraud operation now. A phone, a network, and increasingly an AI tool that can generate a convincing bank statement or pay stub can give someone the tools they need to produce fraudulent documents at a much faster pace. It also means people with less technical skill can create convincing fakes than they could a few years ago, including, apparently, from inside a jail cell.
Every scheme above eventually runs through a document. Whatever the setup and whoever is running it, the outcome often comes down to whether that document can convince someone that it's real.
What I heard at IAFCI lined up with what we've already been seeing in our own data. From June 2025 to May 2026, we saw a 4x increase in the monthly volume of AI-flagged documents across our network. Bank statements, invoices, and payslips make up more than half of everything we flag because those are the documents underwriters rely on most.

Template fraud hasn't gone away, either. It still runs 2 to 3x higher than AI-generated fraud, and the same actors often use both. But AI-generated fraud is the piece moving fastest, which lines up with what I heard about how easy it has become to produce a convincing fake document.
The open-source tools behind this, like FraudGPT, operate without guardrails and continue to improve. As those tools become more accessible, the barrier to creating a fraudulent document keeps getting lower. Our data shows it, and so does a fraud operation being run out of a jail cell.
Fraud today is funded, organized, and increasingly automated, but the common thread across every story is the same. It's getting easier to produce a document that looks real, and that document is usually the thing standing between a fraudster and a payout. The stolen identities, the recruited unhoused individuals, and the prison-run schemes all eventually depend on a piece of paper or a PDF that can pass review.
None of these operations stay hidden forever. Every case above became public because investigators, prosecutors, and postal inspectors did the work to uncover them, often over months or years. I want to thank the people I met at IAFCI and everyone doing this work. It was interesting to hear how they piece together these operations after the fact and how much time and effort goes into understanding what happened and tracking down the people behind it.
At Inscribe, we're focused on a different part of that problem. We help risk teams identify fraudulent documents as they're coming through their applications, so they can catch more of it before it turns into a loss.

Here's a look at our process. We offer a free pilot where we test a sample of your documents to see what types of fraud are coming through your applications. We'll analyze the documents you're actually receiving and help you understand the types of fraud you're dealing with today, including issues that may be difficult for your current review process to catch.

If you want to see what's coming through your own applications, book time with our team.
