AMRTECH ULP PRIVATE 121 #11: Someone May Be Using Your Login

HEROIC analysts reviewed the AMRTECH ULP PRIVATE 121 AMRTECHVIP 11 combolist and found 21,848,902 entries pairing an email address directly with its plaintext password. The file, dated 10-Jan-2026, also records the login URL for each pair. The only way to know if you're affected is to scan your email.

No Cracking Needed: Why 21,848,902 Passwords Are Already Usable

Because these passwords were never hashed, anyone holding the file can read and use them the moment they open it. There is no cracking step and no delay between finding a password and trying it. Paired with the matching email address and URL, an attacker has everything needed to log in directly.

What Was Exposed

• Email Addresses: lets an attacker target you directly with phishing or password reset attempts aimed at your real inbox.
• Plaintext Password: readable the instant the file is opened, so any account still using it can be accessed right now.
• URLs: tells an attacker exactly which site or service each login pair belongs to, speeding up automated login attempts.

What an Attacker Could Do With These 21,848,902 Logins

With a working email and password pair, an attacker can attempt to log into the exact site named in the URL field, and then try that same password on banking, email, and social accounts if it was reused. A successful login can lead to account takeover, fraudulent purchases, or a locked-out owner who no longer controls their own inbox.

Why Files Like This 21,848,902-Entry AMRTECH ULP PRIVATE 121 AMRTECHVIP 11 Batch Keep Getting Reused

A combolist is simply a collection of email and password pairs gathered from many older leaks and stealer logs, then merged into one file for convenience. It is not proof that any single company was broken into; it is a resale package built for speed. Attackers run the whole list against popular sites, hoping a password still works somewhere.

Steps to Take Before You Change Any of These 21,848,902 Passwords

Start by clicking to scan your email and see if it appears in this file. If it does, change that password everywhere you have reused it, not just on the one site named in the record, since the whole point of a combolist is testing one password across many services. Going forward, use a unique password for every account so one leaked combination can never unlock the rest. This applies to personal and work email alike, so check both if you use more than one.
