Check If OCTOPUSCLOUDLOGS Exposed Your Email in This 7,172-Record Breach

HEROIC analysts discovered a stealer log breach attributed to 505 PCS - 09.02.23 - OCTOPUSCLOUDLOGS uploaded by a Telegram User, surfacing on September 3, 2023. The dataset contains 7,172 records pulled from 505 compromised machines, with each entry including an email address, a plaintext password, and the URL of the site the credential belongs to. The logs were distributed freely via Telegram under the OCTOPUSCLOUDLOGS brand, a handle associated with repeated stealer log sharing activity.

Why This Is Dangerous

The OCTOPUSCLOUDLOGS name points to a repeat actor who routinely packages and shares stealer logs on Telegram. Repeat distributors are particuarly dangerous because they build audiences of cybercriminals who check their channels regularly for fresh credential dumps. That means the 7,172 records in this breach were likely downloaded by many actors within hours of being posted, dramatically amplifying the potential for harm.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (websites where credentials were used)

Why This Matters

Stolen credentials with matching site URLs are the raw material for credential stuffing attacks. Automated tools can process thousands of login attempts per minute, testing stolen combos across banks, email services, retail platforms, and social networks. Victims face account takeovers that can lead to identity theft, unauthorized financial transactions, and fraudulent account creation. Even if you only had one account in this breach, that single compromised email and password can unlock dozens of other accounts if you reuse passwords.

How Stealer Logs Work

Stealer logs are created by infostealer malware that installs itself silently on a victims computer, usually via a phishing attack, a fake software download, or a drive-by infection from a compromised website. Once running, the malware scrapes browser-saved passwords, copies active session cookies, and logs any credentials typed into forms. It then transmitts everything to a remote server controlled by the attacker. Those logs are sorted, packaged, and shared on Telegram channels like OCTOPUSCLOUDLOGS, where they are picked up and used by a wide range of malicious actors.
