Wire fraud: how to protect a large transfer

Wire fraud targets big, time-sensitive payments like home closings and business invoices. Scammers hijack email threads and swap in their own account. Here’s how to verify before you send.

Also known as: business email compromise, real estate wire fraud, closing wire scam, payment redirection fraud

How the wire fraud works

  1. 1

    Scammers watch a real deal

    They compromise an email account and read messages about an upcoming payment.

  2. 2

    They send new wire instructions

    Near the deadline, they email updated bank details from a look-alike address.

  3. 3

    You wire to the wrong account

    The details look legitimate, so you send the funds as instructed.

  4. 4

    The money moves out fast

    Wires clear quickly, and the funds are often gone before anyone notices.

Red flags to watch for

  • Last-minute changes to wire or banking instructions.
  • Email pressure to send before a closing or deadline.
  • A sender address that’s one letter off from the real one.
  • New account details that don’t match earlier paperwork.
  • Requests to keep the payment quiet or skip a phone check.
  • Replies that subtly change the reply-to address.

What to do if you’re targeted

  • Stop. Call the recipient on a known number to confirm details.
  • Never use phone numbers found inside the email itself.
  • Re-read the sender address letter by letter.
  • If you already sent it, call your bank to request a recall now.
  • Report it to the FBI’s IC3 and your local police.
  • Tell everyone on the deal so they double-check too.

How Oversight catches the wire fraud

Before you act on new wire instructions, screenshot the email and run a Deep Scan. Oversight compares the sender domain against look-alikes, checks links and attachments, and scores Sender Trust and Auth Score so a spoofed thread stands out. The plain-English breakdown explains why an instruction looks risky. Oversight is assistive, not a guarantee; for any wire, confirm the account by calling the recipient on a number you already had, never one from the message.

Oversight is an assistive tool, not a guarantee. For anything involving money or account access, confirm with the sender using a phone number or website you already trust — never the contact details in the message.

Wire fraud: questions, answered

How can I tell if wire instructions are fake?

Verify by phone using a number you already trusted before this email. Treat any last-minute account change as a red flag until confirmed.

Can a bank reverse a fraudulent wire?

Sometimes, if you act fast. Call your bank immediately to request a recall and file an IC3 report the same day.

Why is real estate a common wire fraud target?

Closings involve large sums and tight deadlines. Scammers exploit the pressure to slip in fake instructions at the last moment.
