Search Your Email: The IRG Listings Dump Exposed 8,184 Records

HEROIC analysts identified a dataset from IRG Listings, a US commercial and industrial real estate platform, that was breached on August 26, 2018. The incident exposed 8,184 records containing email addresses and plaintext passwords, later posted on a hacking forum.

Why the IRG Listings Breach Is Dangerous

Because these passwords were stored as plaintext rather than encrypted or hashed, anyone who downloads the file can read them immediately, no cracking required. Each of the 8,184 exposed accounts comes with a working password paired directly with its email address, ready for an attacker to try the moment they open the file.

What Was Exposed

• Email addresses
• Plaintext passwords

Why This Matters

Real estate platforms often connect to business email accounts, financial tools, and client communications, which raises the stakes for anyone whose credentials appear in this leak. Plaintext email and password pairs are exactly what attackers need for credential stuffing, testing the same login across banking sites, email providers, and other business accounts. That single match can lead to account takeover, financial fraud, or identity theft.

How Database and Combolist Breaches Like This Happen

This breach traces back to a direct compromise of IRG Listings' database, most likely through a vulnerability in the platform's website or login system. Once attackers copied the table of emails and passwords, they packaged the data into a combolist, a compiled file built for easy reuse and resale on hacking forums. Combolists like this one continue to circulate for years after the original breach, which is why 2018 data is still worth checking today.
