Researchers Link the HEAVENLOGSFREE Dump to 6,434 Stolen Credentials

In May 2023, HEROIC analysts flagged a stealer log file distributed through Telegram under the name HEAVENLOGSFREE. The file contained 6,434 records harvested from infected devices, including email addresses, plaintext passwords, and the URLs of the specific services that were compromised. Researchers tracking this breach confirmed the log was shared freely across multiple Telegram channels, giving dozens of threat actors simultaneous access to the same pool of stolen credentails. Although the breach occured in 2023, stealer log data continues to circulate and be exploited long after the initial upload, making this an active risk for anyone in this file who has not changed their passwords.

Why This Is Dangerous

People whose credentials appear in stealer logs are not just victims of one incident. They become high-value targets for a chain of attacks. Because the log contains both the password and the exact URL where it was used, attackers can immediately test those credentials on high-value services. If the victim reuses passwords, attackers can move laterally from one account to another without any additional effort. Victims often never recieve a breach notification because stealer logs rarely trigger the same corporate disclosure requirements as database breaches, leaving affected users unaware for months or years.

What Was Exposed

• Email Addresses -- used as login identifiers across nearly all online platforms
• Plaintext Passwords -- captured in unencrypted, ready-to-use form directly from infected browsers
• URLs -- the precise websites where each set of credentials was harvested

Why This Matters

A stealer log exposes the full picture of a victim's online activity at the moment of infection. Researchers note that attackers can see which banking sites, email providers, and cloud services were active on the device. Credential stuffing tools then automatically test those username and password combinations across hundreds of other platforms. The results can include identity theft, unauthorized financial transactions, account lockouts, and social engineering attacks using information found in the victim's email inbox. Even an account the victim considers secure may be at risk if the stolen password was reused across multiple services.

How Stealer Log Malware Works

An infostealer is a type of malware that silently infects a computer and harvests credentials from saved browser data. Most victims are infected through phishing links, fake software installers, or compromised websites. Once running, the malware collects every saved username, password, and cookie it can find, along with the website URL associated with each one. That data is bundled into a log file and sent to the attacker. Files like HEAVENLOGSFREE are then uploaded to Telegram and shared freely or sold, giving multiple threat actors access to the same pool of stolen credentials. The damage from a single infection can be widespread and long-lasting.

Check If You Are Affected

HEROIC provides a free dark web scanner that checks your email address against more than 400 billion records pulled from breaches, stealer logs, and dark web sources. If you used any online services in 2023 from a device that may have been compromised, your credentials could appear in the HEAVENLOGSFREE log. It takes only a few seconds to run and will tell you immediately if your data has been exposed. Enter your email at HEROIC.com to get your free instant report.
