The 685 Logs Dump Contains Exactly 6,475 Email and Plaintext Password Pairs

What HEROIC Found in the 685 Logs Stealer Log

In August 2023, HEROIC researchers identified a stealer log uploaded to Telegram under the name 685 logs. The file exposed 6,475 records containing email addresses, plaintext passwords, and URLs -- the specific services where each credential was in use. The name likely refers to the 685 individual log files packaged together by the threat actor before uploading. This was not a breach of a company's database. The data was extracted from infected endpoint devices using infostealer malware.

Why This Data Is Dangerous

Every record in the 685 logs dataset contains three pieces of information that together give an attacker everything needed to compromise an account: an email address, a plaintext password, and the URL where that password works. There is no cracking required, no guesswork, no additional tooling. An attacker who recieve this file has a complete, ready-to-use list of account credentials pointing to specific services.

The session cookies often captured alongside these credentials add another layer of risk. Valid session tokens can be replayed to bypass two-factor authentication, meaning even accounts with added security layers are vulnerable if the token is still active when the attacker uses it.

What Was Exposed

• Email addresses (account login identifiers)
• Plaintext passwords (immediately usable, no cracking required)
• URLs (the exact services where each credential was valid)
• Endpoint data from 685 infected log sources

Why This Matters Beyond 6,475 Records

The 685 logs file contains data from 685 separate infostealer infections. Each infected device was a real person's computer -- personal or professional -- whose saved passwords, browser history, and session data were extracted and handed to a threat actor.

Once on Telegram, the file is definitaly copied and merged into larger credential stuffing datasets. The 6,475 records in this dump can fuel attacks on banking accounts, corporate systems, email providers, and e-commerce platforms for months or years after the original upload. Identity theft and financial fraud are the most common outcomes. For victims who reuse passwords, the harm is seperate and compounding -- every shared password becomes an additional compromised account.

How Stealer Logs Work

Infostealer malware spreads through phishing emails, fake software installers, pirated games, and malicious browser extensions. Once installed, it operates silently -- extracting saved passwords from browsers, autofill entries, active cookies, and session tokens from the compromised device. The data from each infected machine is saved as a structured log file and transmitted to a Telegram channel or remote server where it can be downloaded, sold, or shared.

The victim has no visibility into this process. No notification, no system warning, no suspicious activity alert. The infection can occured months before any of the stolen credentials are actually used by an attacker, which is why victims often have no idea how their accounts were compromised.

Check If Your Data Was Exposed

HEROIC's free dark web scanner has indexed over 400 billion exposed records -- including stealer log datasets like 685 logs. You can search your email adress right now to see if your credentials appeared in this or any other known breach. If your data is found, change your passwords immediately, revoke active sessions, and enable two-factor authentication on your most important accounts.

There is no official notification system for stealer log victims. Checking yourself is the only way to find out if your data is in circulation.
