Search Your Email: The OCTOPUSFREELOGS 400-Piece Dump Exposed 2,930 Accounts

In August 2023, HEROIC analysts identified a third stealer log batch from the OCTOPUSFREELOGS Telegram channel, this one labeled AUGUST - 400 PCS - OCTOPUSFREELOGS. The collection was distributed across 400 individual packages containing 2,930 total records, each holding an email address, a plaintext password, and the URL of the website where that credential was captured. The release of three separate OCTOPUSFREELOGS batches during August 2023 confirms this was an active, ongoing operation.

Why the OCTOPUSFREELOGS 400-Piece Collection Is Still a Live Risk

With 2,930 plaintext credentials spread across 400 packages, the OCTOPUSFREELOGS August 400-piece batch offered attackers a pre-sorted, ready-to-use dataset. Each package could be downloaded independently and used to target specific types of accounts without processing the entire collection. The credentials in this file are immediately actionable. No cracking, no decryption. Any attacker with access to even one of the 400 packages has real login credentials for real accounts, along with the URLs needed to deploy them precisely.

What OCTOPUSFREELOGS August 400 PCS Exposed

• Email addresses from compromised user accounts
• Plaintext passwords, usable without any additional steps
• URLs identifying which websites were targeted when the credentials were stolen

Why Multiple OCTOPUSFREELOGS Batches Released in the Same Month Amplify the Threat

The fact that OCTOPUSFREELOGS released 400-piece, 500-piece, and 579-piece batches all in August 2023 suggests the channel had access to a continuous stream of infected device data. Each victim whose credentials appeared in any one of these batches is at risk across all three releases, since their data may have been duplicated or cross-referenced. Credential stuffing operations benefit from this kind of overlapping data, as it allows attackers to verify and retest credentials across multiple logs. Account takeover, identity theft, and financial fraud all become more likely when a victim's email and password appear in more than one active stealer log collection.

How the OCTOPUSFREELOGS Channel Kept Producing New Batches

OCTOPUSFREELOGS operated as a Telegram distribution channel that continuously published new stealer log batches. The underlying malware infected devices through phishing, pirated software, and malicious extensions, then silently collected browser-saved credentials and visited URLs. The operator aggregated this incoming data, sorted it into packages, and released it to subscribers in batches throughout August 2023. This model allowed the channel to maintain subscriber interest and build its reputation as a reliable source of fresh stolen credentials. Victims of this operation likely never knew their device had been infected or that their data was being packaged and shared with thousands of Telegram users.
