The ASU.edu Stealer Log Could Unlock Email, Bank, and Social Logins

HEROIC analysts identified a stealer log tied to asu.edu that a Telegram user uploaded on 10 June 2026. The file contained 5,606 records, each one combining an email address, a plaintext password, and the URL of the login page where that password was captured.

Why This Is Dangerous

This data was not pulled from a hack of asu.edu's own systems. It came from infostealer malware running on individual devices, silently logging every password saved or typed into a browser. Because the passwords in this file were stored in plaintext, anyone who obtains it can read every credential instantly. Paired with the exact URL each login was used on, an attacker gets a direct roadmap to which account belongs to which password.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs tied to each set of stolen credentials

Why This Matters

Students and staff often use one password across email, banking apps, and social media, which means a single stolen login can unlock far more than a university account. Attackers take credentials from logs like this one and test them across other popular sites in a technique called credential stuffing. When a password reused elsewhere still works, the result is account takeover, and from there identity theft or financial fraud becomes possible.

How Stealer Logs Work

Infostealer malware gets onto a device through a malicious download, a fake update, or an infected file, then it quietly copies every saved password, autofill entry, and session cookie from the browser. That data is bundled into a log file and sent back to the attacker without the victim noticing anything unusual. These logs are then traded or dumped on Telegram channels, often within days of the original infection, which is why the passwords inside are frequently still valid.

Check If You Are Affected

If you have an asu.edu account or reuse the same password on multiple sites, it is worth checking whether your information is part of this exposure. HEROIC's free breach scanner checks your email against more than 400 billion leaked records so you can find out and update any exposed password right away.
