The Brown.edu Leak: 593 Logins That Could Unlock More Accounts

HEROIC analysts identified a combolist titled brown.edu - 593 emails uploaded by a Telegram User, shared on 10-Jun-2026. The file contains 593 records, pairing Brown University email addresses with plaintext passwords and the URLs of the accounts they unlock.

Why This Is Dangerous

A university email address is often used to sign into far more than a school portal. Because the passwords in this file are stored in plaintext, anyone who obtains it can immediately try logging into these accounts, and from a university inbox, an attacker may be able to chain their way into a student or staff member's personal email, banking apps, and social media if any passwords were reused.

What Was Exposed

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

Why This Matters

If your brown.edu address is among these 593 records, the risk does not stop at one inbox. Many people use the same password across multiple services, so a compromised university login can quickly become a stepping stone for credential stuffing attacks, leading to account takeover, financial fraud, or identity theft across your other accounts.

How Combolists Work

A combolist pairs stolen email addresses or usernames with matching passwords, typically gathered from past breaches, phishing pages, or stealer malware and packaged together into one file. Lists built around a single email domain, like this one focused on brown.edu addresses, are attractive to criminals because they can be used to target a specific community, from students and faculty to alumni networks.
