The free_smtps Leak Sat Quiet for Months Before Surfacing Online

HEROIC analysts identified a combolist called free_smtps that a Telegram user uploaded on April 3, 2026. The file contains 184 records pairing email addresses with plaintext passwords and the URLs those credentials work on. The data itself appears older, likely pulled together from prior breaches or malware logs, but it only reached a public Telegram channel months after being compiled. Why This Is Dangerous: Each of these 184 records is a ready-to-use login. There is no cracking or guessing involved, an attacker gets the email, the exact plaintext password, and the site it opens, all in one line. What Was Exposed: - Email addresses - Plaintext passwords - URLs tied to each credential pair Why This Matters: A file this size still matters to the people in it. If any of these 184 passwords were reused elsewhere, attackers can run them through automated credential stuffing tools that test the same login across email providers, banking sites, and social media. One reused password is often all it takes to trigger account takeover or identity theft. How This Combolist Was Built: A combolist is a compiled file of email and password pairs, usually gathered from older breaches, phishing hauls, or stealer malware, then sorted by the URL each credential belongs to. Files like free_smtps circulate cheaply on Telegram because they save attackers the work of matching stolen data to a target, and can be fed into automated login tools within minutes.
