Reconstruction · US Dept of Justice, 2025
Clark County, Indiana
Everything Checked Out

Your customer paid a stranger instead of you. Every check you ran said the payments were fine.

You run a family business and you're close to retiring. Your biggest customer pays on time by bank transfer. Someone told her your bank details had changed, and no money arrived for 96 days.

Based on a real case: an email fraud against a family-run business in Indiana, USA, which began in April 2023. Read the US Department of Justice release

The next four decisions are yours.
4 key decisions
You make the owners' four decisions, each on incomplete information.
How you run this business
Your bank details are printed on every invoice.
They haven't changed in eleven years.
Your rule: for any email about payment, check who sent it.

Decision 01 / 04 · The phone call · Accounts receivable

You ring your customer about an overdue balance. She says she's paid every invoice on time, for months, using the new bank details from your email.

What do you ask her for?

She paid into someone else's account

The invoice details were right. The account belonged to a company you've never dealt with.

The account was emptied almost immediately.

Decision 02 / 04 · The forwarded email · Evidence
Mail

The email came from the real address of one of your employees, and every sender check passes. That employee was on leave that week.

What do you have your IT provider check?

Only the sign-in log shows this

Somebody signed in to your employee's mailbox and sent the email from it.

Your rule checks the sender, so it passed an email sent from your employee's own account.

Decision 03 / 04 · The word "future" · Scope

The email asked her to send all future payments to the new account. She did, for months.

What else do you now have to assume?

They read your mail first

They picked the customer by reading your mailbox, so every contact in it is exposed.

Changing the password only stops new sign-ins.

Decision 04 / 04 · Close to retiring · The decision

$182,201.80 has gone to an account that isn't yours. Your customer paid in good faith, on an email from your own address.

What do you do first?

They reported it. It still cost them.

Report it to the FBI and the banks the same day. A transfer can sometimes be frozen or recalled, but only if the banks hear fast.

The owners reported it, and the US Secret Service investigated. The account had already been emptied. To keep the business, they refinanced property, extended their credit and postponed retirement.

The checks in the first three decisions cost nothing and would have stopped this.

The owners had reported it. Even so, they refinanced property, extended their credit and postponed retirement to keep the business.

Primary source. United States Department of Justice, US Attorney's Office, Southern District of Indiana. Press release, November 2025, on the sentencing in a $182k email compromise scheme against a small business in Clark County, Indiana.
justice.gov/usao-sdin/pr/fraudster-sentenced-federal-prison-182k-email-compromise-scheme-targeting-family-owned
Corroborated by a second outlet reporting the same sentencing: suncommercial.com
Verification. The DOJ page returned HTTP 403 to automated retrieval on 20 August 2026. The release was read by a person on 28 August 2026 and checked line by line against this page. Every sourced claim here corroborates, including the restitution figure to the cent. The release describes the victim as a family-run business, in a quoted passage; the wording on this page follows the release.
Taken from the source: a business email compromise scheme beginning April 2023 against a small business in Clark County, Indiana; co-conspirators gained unauthorized access to an email account used by employees; they impersonated a company representative and told another small business in the same county that the victim had changed banking institution; future payments were directed to a specified JPMorgan Chase account; that account was registered to a fictitious entity created solely to receive the funds; $182,201.80 was received; the account was drained quickly and much of the money spent; the defendant left the country and was arrested about six months later re-entering from Canada; the owners, approaching retirement, refinanced property, extended lines of credit and postponed retirement to keep the business; the defendant pleaded guilty to wire fraud and was sentenced to 21 months in federal prison with three years of supervised release, and ordered to pay restitution. The case was investigated by the US Secret Service.
Limit of the source: the release states that access to the mailbox was gained and that, using that access, a company representative was impersonated and the emails sent. It does not state explicitly whether the messages were sent from the compromised mailbox itself. This simulation teaches the account-takeover reading, which is the natural one, and says so here rather than hiding the ambiguity.
Written for the simulation, not sourced: every date, day count and elapsed period on this page, including the ninety-six days and the three months of payments, because the source gives no timeline; the number of invoices, their references and amounts; the wording of the fraudulent email; the accounts payable manager and the phone call; the business's own controls, including the rule made after an earlier fake invoice; the employee's leave and what the experience cost them; the four options at every decision and which is designated correct.
Presented as contested, not settled: whether a customer who paid the wrong account on a written instruction from a compromised mailbox still owes the debt. Liability in these cases turns on jurisdiction, contract terms and the facts. Nothing on this page should be read as legal advice.
Currency and names: figures are US dollars as recorded by DOJ. No individual, company or customer is named here, deliberately, including the defendant and the entity the receiving account was registered to. The plan price is StrongKeep's own published pricing and is not part of the case.
