AlphaFreeLogs 373count Stealer Log: 20,824 US Credentials Exposed (April 2025)

373 Infected Machines, 20,824 Exposed Accounts: The AlphaFreeLogs 373count Stealer Log

In April 2025, a Telegram user distributed a stealer log file labeled AlphaFreeLogs 373count, containing credential data harvested from 373 comprimised devices. The log exposed 20,824 records including email addresses, plaintext passwords, and endpoint URLs -- the latter detail being particularly significant, as it maps each credential pair directly to the service or system it authenticates against. This isn't a passive breach of a stored database; it's the output of active infosteler malware running on real user machines, capturing credentials at the moment of use or from browser credential stores.

What 373 Infected Devices Actually Means

The PCS (piece/device count) metric in stealer logs matters enormously for understanding scope. 373 infected machines yielding 20,824 records means an average of roughly 56 credential pairs per device -- a figure consistent with modern infostealer behavior, which systematically harvests every stored browser credential, session token, and saved password from an infected machine before exfiltration. Each of those 373 devices belongs to a real person whose entire credential ecosystem -- email, banking, work tools, social media -- was extracted in a single compromize operation.

Endpoint URLs: The Most Dangerous Data Field

Unlike traditional database breach dumps that contain username/password pairs without context, stealer logs include the endpoint URLs that each credential authenticates against. This means each record in the AlphaFreeLogs 373count dataset comes pre-labeled: an email/password combination alongside the exact login URL it works with. For attackers, this eliminates the credential-stuffing step entirely -- they know which service each credential targets before attempting a single login. Corporate VPN portals, internal development platforms, banking interfaces, and cloud service consoles all appear in stealer log URL fields, making enterprise accounts disproportionately valuable within these datasets.

Telegram as a Credential Distribution Platform

The choice of Telegram for distributing the AlphaFreeLogs series reflects a broader shift in the threat landscape. Telegram's combination of large group sizes, relative anonymity, and encryption has made it the primary distribution channel for stealer log data in 2025. Operators upload logs for free to establish reputation in credential trading communities, enabling them to later sell higher-value exclusives or services. The "FREE" designation on AlphaFreeLogs batches signals wide distribution -- meaning these credentials have been accessed by potentially thousands of threat actors across multiple Telegram groups before any defensive action can be taken.

Check If Your Data Was Exposed

HEROIC's free breach scanner searches across more than 400 billion exposed records to determine whether your email address appears in known stealer log datasets including AlphaFreeLogs. If you've noticed unexpected login attempts or account access you didn't initiate, checking your breach exposure status is an important first step.
