Durham University Breach: 2,956 durham.ac.uk Logins Leaked

What HEROIC Analysts Found

In June 2026, HEROIC analysts identified a stealer log shared on Telegram containing 2,956 records tied to durham.ac.uk, the domain used by Durham University in the United Kingdom. The log included email addresses, plaintext passwords, and the login URLs those credentials belong to. This data wasn't pulled from a university server breach. It was harvested from infected personal devices belonging to people who use durham.ac.uk logins.

A UK University Domain in the Crosshairs

University accounts are a common target in stealer logs because students and staff use them for years, often linking them to library systems, email, VPN access, and even financial aid portals. A leak tied specifically to a UK academic domain like durham.ac.uk gives attackers a ready-made list of accounts they know are active and valid, without having to guess who uses the service.

What Was Exposed

• Email addresses
• Plaintext (unencrypted) passwords
• Login URLs tied to each set of credentials

Why This Matters

Because the passwords in this log are stored as plain text, they can be used immediately without any cracking. Students and staff who reused their durham.ac.uk password on personal accounts are exposed to credential stuffing, where the same email and password combination is tested automatically across banking, shopping, and social media logins. A compromised university email can also be used to reset passwords on other services tied to that address.

How Stealer Logs Target University Accounts

This leak traces back to infostealer malware, malicious software that infects a device, often through a cracked textbook download, fake study tool, or malicious link, and then quietly copies saved browser passwords, autofill data, and login sessions. The results are packaged into a log file and posted to Telegram. From there, other actors merge logs together into large searchable collections, allowing anyone to pull out every credential connected to a specific domain like durham.ac.uk.

Check If You Are Affected

If you use or have used a durham.ac.uk account, it's worth checking whether your credentials are part of this leak. HEROIC's free breach scanner checks your email against a database of more than 400 billion exposed records, including stealer logs like this one, so you can find out in seconds and secure any accounts before someone else logs in first.
