Good Hotmail Neo3690 Leak: 2,814 Accounts Ready to Steal

HEROIC's monitoring infrastructure detected a stealer log file labeled "Good Hotmail Neo3690" uploaded to Telegram in January 2025. The file contains 2,814 credential records targeting Hotmail accounts, with every password stored in plaintext. The "Good" prefix in the filename signals to buyers that these are high-quality, tested credentials — making this dataset especially dangerous for the affected account holders.

Readable Passwords Eliminate Any Security Buffer

Each of the 2,814 passwords in this leak is stored as unencrypted text. There is no hashing, no salting, no cryptographic protection of any kind. An attacker who obtains this file can log into accounts instantly. For Hotmail and Microsoft accounts, successful login means access to email, OneDrive files, Skype conversations, and potentially linked Xbox and Office 365 accounts — all from a single plaintext password.

What Was Exposed

• Email Addresses — Hotmail accounts serving as Microsoft identity anchors
• Plaintext Passwords — unprotected and usable without any technical effort
• URLs — the login pages and services from which the malware captured each credential

The Downstream Threat of Compromised Email Accounts

Attackers prize email credentials above all others because a compromised inbox unlocks a cascade of additional accounts. Password resets for banking, shopping, and social media sites all flow through email. An attacker inside your Hotmail account can trigger resets, intercept confirmation codes, and seize control of services you never expected to be at risk. The 2,814 records in the Neo3690 file represent 2,814 potential cascade attacks waiting to happen.

Neo3690: Threat Actor Behind the Collection

The "Neo3690" identifier points to the threat actor or distribution handle that curated this file. The underlying data originates from infostealer malware — programs like RedLine, Lumma, or Vidar that silently infect devices and extract every credential saved in the browser. Neo3690 appears to have filtered the raw stealer logs specifically for working Hotmail credentials, creating a curated, high-value dataset before distributing it on Telegram channels frequented by cybercriminals.

Check If Your Credentials Were Exposed

If you use a Hotmail or Outlook email account, the Good Hotmail Neo3690 file could contain your credentials. HEROIC's data breach scanner searches across more than 400 billion compromised records to determine if your email or password has been leaked. Identifying your exposure now lets you change your password and enable multi-factor authentication before an attacker turns your email account into a launchpad for broader identity theft.
