The hits_smtp Leak Put 6,725 Stolen Email and Password Pairs Online

HEROIC analysts found a combolist called hits_smtp uploaded to a Telegram channel on July 10, 2026. The file contains 6,725 records of email addresses, plaintext passwords, and URLs tied to SMTP mail servers. Why This Is Dangerous: The credentials in this file are stored in plaintext, meaning no password cracking is required before they can be used. With working SMTP logins, an attacker can send email through a legitimate server, making phishing and spam messages far more convincing since they appear to come from a real, working account. What Was Exposed: - Email addresses - Plaintext passwords - URLs for SMTP mail servers Why This Matters: 6,725 people now have credentials circulating in a file built specifically to target mail servers. Beyond abuse of the mail accounts themselves, attackers commonly reuse these same email and password combinations against banking, shopping, and social media sites, since so many people repeat passwords across accounts. That opens the door to credential stuffing, account takeover, and financial fraud. How a Combolist Like This Works: Lists like hits_smtp are usually built by scanning for exposed or weakly secured mail servers, harvesting valid logins, and combining them into a single file for resale or distribution on Telegram. The 'hits' in the name typically refers to successful, verified login attempts rather than random guesses, which makes this kind of list especially reliable for criminals. Check If You Are Affected: With thousands of working credentials in circulation, it is worth checking your own exposure directly. HEROIC's free breach scanner checks your email against more than 400 billion leaked records so you can see your risk in seconds.
