How the Event Training Australia Leak Exposed 6,104 MD5 Hashes

HEROIC analysts reviewed a dataset tied to Event Training Australia, a now-defunct professional training platform, that surfaced on a hacking forum around August 26, 2018. The leak contains 6,104 records, each pairing an email address with an MD5 password hash. The company is no longer operating and never confirmed this incident, so this analysis is based on the leaked data itself.

Why This Is Dangerous

MD5 hashing hasn't held up well against modern computing power, tools built specifically to crack MD5 hashes can work through large batches in a short time using precomputed tables. That puts a real number of these 6,104 passwords within reach of being reversed into plaintext. Once cracked, each one is paired with a working email address, ready to be tried on other accounts.

What Was Exposed

• Email addresses
• MD5 password hashes

Why This Matters

Because Event Training Australia no longer exists, there's no company left to force a password reset or notify the people affected, so the exposure just sits there, quietly usable by anyone who finds it. Cracked credentials from leaks like this typically end up in combolists, which attackers run through automated credential stuffing tools against other websites. If a former user of this training platform reused their password anywhere else, they remain exposed to account takeover and identity theft even years after the platform shut down.

How Database and Combolist Leaks Work

This kind of leak generally begins with an attacker finding a vulnerability in a website's backend, an outdated content management system, unpatched software, or a misconfigured server, and extracting the entire table of user credentials. MD5 hashing offers only limited protection since cracking tools can process it quickly, especially against common or reused passwords. Once cracked, the data usually gets folded into larger combolists and reposted across hacking forums for years, which is exactly why a leak from a defunct 2018 platform can still matter today.

Check If You Are Affected

Since Event Training Australia is no longer around to notify you, HEROIC's free breach scanner is the quickest way to check your email address against more than 400 billion leaked records, including this one. If you find a match, change that password anywhere else you've used it and turn on multi-factor authentication on your important accounts.
