Check Yourself: 1.17M US Logins Leaked in Telegram Domain Dump

On January 14, 2023, a Telegram user uploaded a stealer log labeled "1.3KK USA BEST UHQ DOMAINS GOOD FOR EVERYTHING," exposing 1,176,800 records. The file includes email addresses, plaintext passwords, and the URLs of the login pages where each set of credentials was captured, a massive collection built from malware quietly running on infected devices across the US.

What "1.3KK" Actually Means for You

In dark web shorthand, "KK" stands for thousands of thousands, so "1.3KK" advertises roughly 1.3 million records, and the real count here lands at 1,176,800. The label "UHQ" (ultra high quality) and "good for everything" tell you exactly how this file was marketed: as a large, verified batch of working US logins suitable for any kind of account takeover an attacker wants to attempt. Before you assume a leak this size does not include you, it is worth checking directly.

What Was Exposed in This Domain Dump

• Email addresses
• Plaintext passwords
• URLs of the login pages tied to each account

Why This Matters

A file of this size is built for scale. Attackers run automated credential stuffing tools against lists like this one, testing each email and password pair against banking sites, email providers, and online retailers in bulk. Every match becomes an account takeover, and from there the path to identity theft and financial fraud is short, especially when a compromised email account controls password resets for everything else a person owns.

How Large Stealer Log Dumps Like This Get Built

Infostealer malware infects devices, often through fake downloads, cracked software, or phishing links, and silently copies saved browser passwords, autofill data, and login URLs. A single infected device might only yield a handful of accounts, but when malware operators combine the output of thousands of infections into one file, the numbers climb into the millions. Files are then labeled and marketed on Telegram, "fresh," "valid," or "UHQ," to signal how usable the credentials inside are believed to be.
