You Should Check Whether Your 53hotel.com.tw Login Leaked

You may not know this file exists, but if you have ever used 53hotel.com.tw, it is worth five minutes to check. HEROIC analysts found 5,894 email and plaintext password pairs referencing the site inside a combolist uploaded to Telegram on 29 Nov 2020, each one tagged with the URL it was pulled from, so before you decide this does not apply to you, take a moment to scan your email.

Why You Cannot Tell From the Outside

There is no notification, no locked account, no visible sign that your credentials sit in a file like this one. The only way to know is to actively check, because nothing about how your account behaves day to day will change until someone actually uses the leaked password.

What Was Exposed

• Email addresses, used to target the same person on other services.
• Plaintext passwords, readable and usable without any cracking required.
• URLs, showing which login page each pair was collected from.

Why This Matters

The gap between a leak existing and someone using it against you is invisible from your side. Checking is the only way to close that gap on your own terms instead of finding out after the fact.

How This Kind of File Gets Made

Combolists are generally built by pulling together older leaked credentials or stealer output and formatting them into a single list of email and password pairs, which is then passed around for testing against other services entirely unrelated to the original source.

How Long Does Checking Actually Take?

Less time than it took to read this article so far. Scan your email to see if your address is among the 5,894 exposed here, and if it is, change that password everywhere you have reused it, across personal accounts and work accounts alike, starting today rather than waiting for a reminder.
