Hotmail Fresh B4_Jx Telegram Stealer Log Leaked 75 Accounts

HEROIC analysts identified this stealer log on April 4, 2026. The breach exposed 75 records, with stolen data including email addresses, plaintext passwords, and URLs. The source is identified as the Hotmail Fresh B4_Jx stealer log.

Why This Is Dangerous

These 75 records carry both a Hotmail designation and a Fresh label, indicating recently stolen Hotmail credentials that had not yet been detected or reset. Email account access is particularly damaging because attackers can use a compromised inbox to intercept password reset links and take over any other account linked to that address.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of associated Hotmail login pages

Why This Matters

Hotmail and Outlook accounts serve as recovery addresses for banking, social media, and retail platforms. An attacker with access to a Hotmail inbox can reset passwords across those linked services, enabling account takeover, identity theft, and financial fraud with minimal effort.

How This Stealer Log Works

Infostealer malware installs itself on a victim's device through a fake download or cracked application, then silently harvests saved browser passwords and site URLs. Hotmail-labeled batches are created by sorting credentials containing Hotmail or Outlook login URLs, then distributed as targeted log files on Telegram channels where buyers search for email account access specifically.
