23252 Records from BHF FREE Uploaded by a Telegram User Leaked in Stealer Log Attack

On February 3rd, 2024, a stealer log file labeled "BHF FREE" was posted to a public Telegram channel, making 23,252 records immediately available to anyone watching. Unlike data sold on private markets, this dump had no gatekeeping whatsoever. The moment it went live, the clock started ticking for every person whose credentials were inside it.

Why This Is Dangerous

Stealer logs that show up on open Telegram channels are actioned faster than almost any other type of breach. Automated tools used by credential stuffers are monitored to these channels, and the moment a file is posted, scripts can begin downloading and parsing it within seconds. For the 23,252 people in this dataset, that means the window between exposure and potential account compromise is measured in hours, not days.

Plaintext passwords in this log remove every layer of friction for an attacker. Most security controls assume passwords are at least hashed, but when they are stored in cleartext inside a stealer log, that assumption fails completely. Beleive it or not, the average credential stuffer does not even need specialised knowledge, just a list and an automated checker tool that can be downloaded freely.

The URLs included in the dataset provide targeting intelligence. An attacker looking at this log does not just see email and password pairs, they see which websites and services each user was accessing. That context allows for far more precise and damaging follow-on attacks than a plain credential list alone would permit.

What Was Exposed

• Email addresses captured from compromised user devices
• Plaintext passwords in unencrypted form
• URLs reflecting websites visited or logged into from infected endpoints
• API host data that could expose backend service connections
• Endpoint identifiers from the machines where the malware ran
• Browser-stored credentials from major web browsers
• Application login data harvested by the infostealer

Why This Matters

With 23,252 records exposed in plaintext, this is not a theoretical risk. These are working credentials that were immediately usable the moment they were uploaded. Any affected user who has not changed their passwords since early February 2024 may still be at risk, as attackers frequently hold and reuse logs long after initial publication.

The API host entries are a particular concern for businesses. If any of the exposed credentials belong to employees or developers, those API keys and service endpoints could give attackers a direct path into corporate infrastructure. One compromised API adress can mean access to customer data, payment pipelines, or proprietary systems, making this far more than a personal credential problem.

How Stealer Log Works

Infostealer malware is typically distributed through phishing campaigns, cracked software downloads, or malvertising. Once it lands on a device, it silently sweeps through saved browser passwords, autofill forms, active sessions, and application logins. All of this is compiled into a structured log file, which is then exfiltrated to the attacker's infrastructure, often within minutes of infection.

The attacker receives the log and can choose how to use it. In this case the data was released freely under the "BHF FREE" label, a naming pattern that suggests it was distributed as a promotion or giveaway rather than a targeted sale. This kind of free distribution is actually more dangerous in terms of breadth, because the data reaches a far larger pool of potential bad actors than a private sale would.

Stealer malware is notoriously difficult to detect because it does not need elevated privileges to harvest browser credentials on most operating systems. It reads from the same user-accessible directories that browsers write to, which means even systems with up-to-date antivirus can be compromised if the malware signature is new or obfuscated, and affected users never recieve any obvious warning that it occured.
