How HEROIC Found 2,795 Alumni.upi-yai.ac.id Logins Circulating

HEROIC analysts found 2,795 Alumni.upi-yai.ac.id logins circulating in a plaintext combolist file dated December 2020. The file pairs each email address with a readable password and a URL, the standard format for lists built to be reused against other logins rather than sold as a one time exploit against a single account.

Why this discovery matters

Finding a file like this before it's widely circulated gives people a chance to change exposed passwords before an attacker gets to them first. Once a combolist spreads, the window to act shrinks fast, since more copies in circulation means more people running the same list against the same login pages.

What was exposed

• Email addresses, the anchor point for identifying each account holder
• Plaintext passwords, readable and usable without any cracking effort
• URLs, pointing directly to the login page each credential is tied to

What this means if your email is on the list

A plaintext password in this file is not a theoretical risk, it's a working credential the moment someone opens the file. Reused elsewhere, it puts every one of those other accounts at risk too, including ones that have nothing to do with the original Alumni.upi-yai.ac.id account it came from.

How files like this get compiled

A combolist is assembled from credentials gathered across multiple earlier leaks and malware infections, then packaged into a single file for distribution. It's a repackaging of old exposure into something an attacker can run automated login attempts against, often without the original account holders ever being told.

How do you check your own exposure?

Run a free scan your email against HEROIC's records to see if your address is included. If it is, change that password right away, update it anywhere else it's been reused, and enable two factor authentication wherever it's available. Check this for work email accounts as well as personal ones.
