Identity Theft Risk Rises After aberdeen.ac.uk Leaked 660 Logins

HEROIC analysts identified the aberdeen.ac.uk combolist in June 2026, after it was uploaded to a Telegram channel used to trade stolen credentials. The file contains 660 records, including email addresses and passwords, and the specific login URLs tied to each account, making it a ready-made toolkit for anyone who wants to try those credentials elsewhere.

Why the aberdeen.ac.uk Combolist Is Dangerous

Every record in the aberdeen.ac.uk file pairs an email address with a plaintext password, along with the URL where that password was used. That combination is exactly what an attacker needs to log in as the victim, no guessing required. Because the matching URL is included, an attacker does not even need to figure out which site the credentials belong to, they can go straight to the login page and try them.

Most people reuse passwords across several accounts. That habit is what turns a 660-record leak like aberdeen.ac.uk into a much bigger problem than the number suggests, because one exposed password can unlock email, banking, or social media accounts that have nothing to do with the original list.

What Was Exposed in the aberdeen.ac.uk Combolist

• Email Addresses
• Plaintext Password
• URLs

In total, 660 records were included in the aberdeen.ac.uk file.

Why This Matters for Anyone in the aberdeen.ac.uk Data

Leaked email and password pairs feed directly into a handful of well-known attack methods. Credential stuffing tools can take the 660 entries in the aberdeen.ac.uk file and test them automatically against banking sites, email providers, and shopping accounts within seconds. If even one attempt succeeds, the attacker has an open door for account takeover.

From there, the damage compounds quickly. An attacker who gets into an email account can reset passwords on other services, request password resets, or use the inbox to answer security questions. That is how a leak involving plaintext passwords turns into identity theft or financial fraud, even when the original list looks small.

How the aberdeen.ac.uk Combolist Came Together

A combolist is not a single company's breach. It is a curated file of email-and-password pairs pulled together from older leaks, malware logs, and previous dumps, then repackaged and shared under a new name, in this case "aberdeen.ac.uk". Whoever assembled the aberdeen.ac.uk list combined 660 of these pairs into one file and posted it in a Telegram channel where other threat actors could download it for free or in exchange for reputation on the channel.

What makes combolists dangerous is not novelty, it is convenience. Attackers do not need to breach anything themselves. They simply load a combolist like this one into automated tools and start testing the credentials against popular websites and services.
