Your Data May Be Exposed: Hotmail Fresh B4_Jx Leaked 591 Logins

In April 2026, HEROIC analysts found a file named Hotmail Fresh B4_Jx being shared on a Telegram channel used to trade stolen login data. The file contained 591 records pairing email addresses with plaintext passwords, along with the URLs of the sites those logins were captured from. Why This Is Dangerous: This is a small file, but the risk to each person in it is the same as in a much larger breach. The passwords are stored in plain, readable text, so anyone who gets the file can log in immediately without needing to crack or guess anything. What Was Exposed: - Email addresses - Plaintext passwords - Associated login URLs Why This Matters: A list this size is easy to overlook, but small combolists like this one circulate constantly on Telegram and get folded into larger credential stuffing tools within days. If any of these 591 people reused their Hotmail password on another account, email, banking, or shopping, that account is now at risk of takeover, identity theft, or fraud. How a Combolist Like This Works: Files like Hotmail Fresh B4_Jx are usually assembled from stealer malware logs or recycled from older breaches, then sorted by email provider and given a catchy name before being uploaded to Telegram. Buyers and other criminals use these smaller, freshly sorted lists because they are more likely to still be active than older, widely circulated dumps. Check If You Are Affected: Search your email address in HEROIC's free breach scanner, which checks against more than 400 billion exposed records including this one. If your Hotmail account shows up, change the password right away and update it anywhere else you used it.
