The Know Your College Breach Happened in 2017. Passwords Just Went Public.

HEROIC analysts identified the Know Your College breach while tracking credential stuffing lists on dark web forums, where the exposed data has been actively traded and repackaged. The breach occured in December 2017 and affected 154,370 users of this Indian educational information portal. What makes this breach seperate from others we regularly track is the storage method used for passwords: they were kept in plaintext, meaning absolutely no encryption or protection was applied. Anyone who obtained this database could read every user's actual password directly, with no cracking required at all.

Why Plaintext Passwords From Know Your College Are Especially Dangerous

Most breaches expose password hashes, which at least require some effort to crack. The Know Your College breach exposed real, readable passwords in plain text. That means attackers who obtained this database immediately had working login credentials for over 154,000 accounts. Those email and password pairs were almost certainly tested against Gmail, Facebook, banking apps, and other services where victims may have recieved no warning at all. Password reuse is extremely common, and plaintext credential dumps are among the most valuable assets circulating on dark web marketplaces.

What Was Exposed in the Know Your College Breach

• Email Address
• Plaintext Password

Why the Know Your College Breach Still Matters Years Later

Credential stuffing attacks are fully automated and scale effortlessly. With 154,370 email and plaintext password pairs from the Know Your College breach, criminals can run attacks against hundreds of other websites simultaneously. If even a small percentage of those passwords were reused elsewhere, the result is account takeovers, unauthorized purchases, identity theft, and financial fraud. Educational platforms often attract younger users who may use the same password across many services and are less likely to have changed it since 2017.

How a Database Breach Works

A database breach occurs when an attacker gains unauthorized access to a website's data storage system, typically by exploiting a weakness in the site's code, server setup, or login system. In the case of Know Your College, the database was not only breached but was storing passwords in an entirely unprotected format. Responsible websites store passwords as hashed values, meaning even if a database is stolen, the actual passwords cannot be read directly. Storing passwords in plaintext is a fundamental security failure that put every user at immediate risk.
