Password Reusers Beware: The mansory4 Combolist Exposed 4.97M Logins

On July 28, 2026, HEROIC analysts identified a combolist named "mansory4" uploaded to a Telegram channel, containing 4,977,413 records of email addresses, plaintext passwords, and associated URLs. This is one of the larger combolists HEROIC has logged from Telegram sources recently, and the scale changes the risk calculation significantly. Why This Is Dangerous: Nearly 5 million login pairs in one file means attackers have an enormous, ready-to-use dataset for automated attacks. The passwords are stored in plaintext, so there is no cracking step between download and use. What Was Exposed: The leak includes email addresses, plaintext passwords, and the URLs associated with each account, giving attackers a direct roadmap of where each stolen credential can be used. Why This Matters: At nearly 5 million records, this combolist is exactly the kind of data set that powers large-scale credential stuffing campaigns. Anyone who reuses a password across more than one site is at meaningfully higher risk if their email shows up in a file this size, since automated tools can test millions of logins against major platforms in a matter of hours. How a Combolist Like This Works: A combolist is built by merging login credentials from multiple sources, often older breaches and stealer logs, into a single large file. The bigger the combolist, the more valuable it is to criminals, because it increases the odds that a meaningful percentage of the logins still work somewhere. Files like "mansory4" are shared and resold in Telegram channels dedicated to trading stolen data.
