Your Hotmail Login May Be at Risk: TXTVALID Leak Exposed 674 Records

HEROIC analysts identified a Telegram file called "Hotmail TXTVALID" that surfaced on April 17, 2026. The "TXTVALID" label suggests the 674 credential pairs inside had already been checked and confirmed to work before being shared. Why This Is Dangerous: A validated combolist is more dangerous than a random dump because someone has already confirmed the logins work. Combined with plaintext passwords and account URLs, this file gives an attacker a ready-to-use list of 674 working Hotmail logins. What Was Exposed: - Email addresses - Plaintext passwords - Account login URLs Why This Matters: Validated credential lists move faster through criminal networks because buyers know the logins are live. Anyone whose Hotmail credentials appear in this file faces immediate risk of email takeover, and further risk anywhere else they reused the same password, including banking and shopping accounts. How This Telegram Combolist Works: Attackers often run stolen credential lists through automated checking tools before distributing them, filtering out dead logins and keeping only the ones, like these 674, confirmed to still work. This validation step is what turns a raw dump into a more valuable and more dangerous file.
