Who’s Exposed in the 1.7K UNIVERSIDAD_POLITECNICA_DE_TULANCINGO File

HEROIC analysts found a combolist labeled 1.7K UNIVERSIDAD_POLITECNICA_DE_TULANCINGO, uploaded to Telegram in August 2026, containing 1,760 login records built from email addresses, plaintext passwords, and the web addresses each one unlocks. The name points to a university community whose logins ended up in this file. Scanning your email is the only way to know if yours is among the 1,760.

Who Actually Shows Up in a File Like This

A combolist tied to a university name usually reflects students, staff, or alumni who used that email address somewhere else online, not a single group targeted directly. Anyone whose login was swept into this file faces the same exposure, whether they still have a connection to the institution or not.

What the 1.7K UNIVERSIDAD_POLITECNICA_DE_TULANCINGO File Holds

• Email Addresses: gives an attacker a confirmed target for phishing messages or login attempts.
• Plaintext Password: fully readable, so it can be used immediately without cracking.
• URLs: shows exactly which login page each credential pair was captured from.

Small Numbers, Real Consequences

1,760 records is a small file next to some of the leaks in circulation, but every row still represents a working login. If a password here has been reused on an email account or anything financial, that account is exposed just the same as if it came from a much larger breach. Account takeover and identity theft do not scale down with file size.

How a Combolist Like This Gets Labeled

Files named after an institution are usually built by sorting leaked or reused credentials by the email domain they share, not by breaking into that institution's own systems. The 1.7K UNIVERSIDAD_POLITECNICA_DE_TULANCINGO label marks a shared email pattern among the people in this file, nothing more.

Check Before Your Login Gets Used Elsewhere

Scan your email to find out if your address is in this file. If it is, change that password everywhere you have reused it, starting with your email and any accounts tied to money. This applies whether the email you use is personal or tied to work, since either can turn up in a file like this.
