theatredatabase.co.uk Dump Has Exactly 66,112 Password Pairs

A Plaintext Combolist Tied to theatredatabase.co.uk Surfaced on Telegram

On 20 August 2023, HEROIC analysts identified a combolist labeled "theatredatabase.co.uk_66.116_plaintext," uploaded to Telegram by an individual user. The file contained 66,112 records, each pairing an email address with a plaintext password and the URL of the site the credentials were meant to unlock. The file name references theatredatabase.co.uk, suggesting the credentials trace back to that site's user base before being compiled and shared as a standalone combolist.

Why This Is Dangerous

Every password in this file is stored in plaintext, meaning there is no encryption standing between an attacker and a working login. Anyone who downloads the list can read a person's exact password, next to their exact email address and the exact site it was meant for. For the 66,112 people in this file, that is enough for an attacker to log straight in, no cracking or guessing required.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the associated login pages

Why This Matters

Small combolists like this one are just as useful to attackers as massive ones, they simply get less attention. Criminals run these credentials through automated credential stuffing tools that test each email and password pair against email providers, banking sites, and retail accounts. Anyone who reused this password elsewhere risks account takeover, and from there, identity theft and financial fraud become a real possibility.

How Plaintext Combolists Like This One Circulate

Combolists such as this one are usually assembled from a site's user records, sometimes taken directly, sometimes gathered through smaller breaches or scraping, and formatted into a simple list of email, password, and site URL. Because the passwords are already in plaintext, no additional cracking work is needed before the file is ready to use. These lists are then shared for free or sold in Telegram channels dedicated to trading stolen credentials.

Check If You Are Affected

If you have ever had an account tied to theatredatabase.co.uk or reused a password across multiple sites, it is worth checking now. HEROIC's free breach scanner checks your email address against a database of more than 400 billion leaked records, including combolists like this one, so you can see your exposure and update any at-risk passwords right away.
