The Isfahan University Leak Could Unlock Accounts Across Services

Why This Isfahan University Data Puts You at Risk

Ready-to-use email and plaintext password combinations enable credential stuffing attacks at scale. Attackers target banking apps, email providers, and social networks, and victims who reused their password face compounding risks including identity theft and financial fraud.

How Database Breaches Work

Database breaches occur when attackers exploit vulnerabilities in a website's infrastructure to extract stored user data. Once inside, they download the entire user table -- including credentials -- and distribute the data on underground forums. Combolists are then assembled from multiple breaches to amplify the scale of attacks.
