6,825 Passwords From OCTOPUS FREE LOGS Just Surfaced on the Dark Web

In August 2023, HEROIC analysts identified a stealer log dataset circulating on Telegram under the name OCTOPUS FREE LOGS. The log, uploaded by an anonymous Telegram user, contains 6,825 records pulled directly from infected devices. Each record includes a victim's email address, their plaintext password, and the URL of the site or service the credentials belong to. Because the passwords are stored in plaintext, there is no decryption required: anyone who downloads this file can use the credentials immediately.

Why the OCTOPUS FREE LOGS Stealer Log Is Dangerous

Most credential leaks expose hashed passwords that require time and computing power to crack. This log skips that step entirely. Every password in the OCTOPUS FREE LOGS dataset is in plain readable text, paired with the exact email address and the website it unlocks. An attacker does not need any special tools. They can open the file, pick a record, and attempt to log in within seconds. The inclusion of URLs makes it even more targeted: attackers know exactly which service each credential belongs to, allowing them to skip guessing and go straight to the login page.

What Was Exposed in OCTOPUS FREE LOGS

• Email addresses
• Plaintext passwords
• URLs (the websites and services associated with each credential)

Why This Matters

Plaintext passwords paired with email addresses are the most immediately actionable type of leaked credential. Attackers use these records for credential stuffing: they feed the email and password pairs into automated tools that attempt to log in to dozens of services at once. Because many people reuse the same password across multiple accounts, a single exposed credential can unlock email inboxes, social media profiles, online shopping accounts, and even banking portals. The URLs in this dataset tell attackers which services were already compromised on the infected device, but the real threat extends to every other site where the victim used the same password.

How Stealer Logs Like OCTOPUS FREE LOGS Work

Stealer logs are produced by a category of malware known as infostealer software. These programs are typically delivered through phishing emails, malicious downloads, or compromised software installers. Once installed on a victim's device, the malware runs silently in the background, harvesting saved passwords from browsers, session cookies, and autofill data. It captures credentials as users type them into login forms, recording the associated URL at the same time.

After harvesting, the malware packages all collected data into a compressed log file and sends it to a command-and-control server controlled by the attacker. These log bundles are then sold or freely distributed on dark web forums and private Telegram channels, often in bulk packages with names like "FREE LOGS" to attract downloaders and build reputation within criminal communities. The OCTOPUS FREE LOGS package follows this exact pattern: collected from infected US-based devices and uploaded to Telegram for anyone to access.

Check If You Are Affected

HEROIC maintains a breach intelligence database of more than 400 billion records, including stealer logs like this one. Run a free scan to see if your email address or credentials appear in the OCTOPUS FREE LOGS dataset. Early detection gives you time to change passwords and secure your accounts before attackers act on the data.
