One Telegram Post, One File Named US: Just 9 Logins Leaked
On 19 June 2026, HEROIC analysts spotted a small combolist file simply named "US" uploaded to a Telegram channel that shares stolen login credentials. The file held only 9 records, each pairing an email address with a plaintext password and the URL of the account it opens.
Why This Is Dangerous
A small file does not mean small risk. Because the 9 passwords here are stored in plaintext, whoever holds the file can read and use them immediately, no cracking involved. Attackers routinely combine tiny files like this one with larger lists before running them through automated login tools.
What Was Exposed
- Email addresses
- Plaintext passwords
- URLs showing which account each pair unlocks
Why This Matters
Even a handful of exposed credentials matters to the people behind them. If any of the 9 accounts in this file reused their password elsewhere, an attacker has everything needed to try logging into that other account too.
How Combolists Work
A combolist is a plain text file of "email:password" pairs, usually pulled from older breaches or stealer-infected devices and shared for free or sold cheaply on Telegram. Even small combolists get merged with other files to build larger master lists that attackers run against banking, email, and shopping sites using automated credential stuffing tools.
Check If You Are Affected
