Search Your Email: The GitHub_Logins Dump Exposed 12,244 Accounts

HEROIC analysts identified a combolist titled "GitHub_Logins," uploaded to a Telegram channel on March 19, 2026. The file contains 12,244 records pairing email addresses or usernames with plaintext passwords, along with the login URLs each credential unlocks.

Why This Is Dangerous

Because the passwords in this dump are stored in plaintext, anyone who downloads the file can read and use the credentials immediately, no cracking or decryption required. Paired with a working login URL for each record, an attacker has everything needed to sign in directly, without the failed login attempts that usually trigger security alerts.

What Was Exposed

• Email addresses
• Plaintext passwords
• Account login URLs

Why This Matters

Credentials like these rarely stay contained to one site. Attackers routinely test leaked email and password pairs against banking portals, email providers, and social accounts, a technique known as credential stuffing. If a password from this list has ever been reused on another account, that reuse, not the original login, becomes the real vulnerability.

How Combolists Work

A combolist is a plain text file pairing usernames or emails with passwords, typically compiled from older leaks, malware infections, or manual collection, then repackaged and shared on platforms like Telegram. Because a combolist can blend data from many sources, the credentials inside can remain usable long after the data first leaked.
