The hulk_logs 800 LOGS Breach Happened in August 2023. The Data Is Still in Circulation.

HEROIC Found 9,519 Exposed Records from the hulk_logs 800 LOGS Stealer Dataset (August 2023)

In August 2023, a Telegram user associated with the hulk_logs channel uploaded a stealer log package containing 800 infected machine logs and 9,519 harvested credential records. HEROIC analysts identified this dataset and confirmed it contained email addresses, plaintext passwords, and the URLs of the services where those credentials were captured. The hulk_logs channel was an active Telegram distribution point for stealer log data, and this 800-log package was one of its larger releases.

The hulk_logs Stealer Package Was Active in August 2023. The Data Is Still in Circulation.

The hulk_logs 800 LOGS dataset was uploaded to Telegram in August 2023. That was nearly two years ago. But stealer log data doesn't expire. Those 9,519 credential records have been available to criminal networks since the moment they were posted, and each time a dataset like this changes hands, it gets incorporated into larger credential collections that are used in new waves of attacks.

Credential stuffing campaigns, account takeover operations, and identity fraud rings all draw from pooled stealer log datasets. If your credentials were in the hulk_logs upload when it first appeared in August 2023, they have had nearly two years to be exploited by a growing number of threat actors who have accessed the data since. The plaintext format means there was never any barrier to use — no cracking required, no technical skill needed.

What Was Exposed in the hulk_logs 800 LOGS Upload

• Email addresses (complete account identifiers for login)
• Plaintext passwords (immediately usable since the day of upload)
• URLs (showing exactly which services were targeted per record)

All 9,519 records contain this complete data combination. The 800 infected machines in this package each contributed multiple credential records, producing a dataset that covers a wide range of services and account types.

Why Stealer Log Exposure Has Compounding Long-Term Risks

The danger from stealer log data is not a single event — it compounds over time. In the months after a dataset is released, it gets absorbed into aggregated credential collections. Those collections are used in large-scale credential stuffing attacks targeting email providers, banks, and corporate systems. Attackers who recieve access to your email account can use it to reset passwords on every other service you've signed up for. Identity theft, financial fraud, and account hijacking all follow.

Even if you changed a specific password after hearing about this breach, any account where you used a seperate similar password may still be at risk. The combination of email address and base password pattern gives attackers enough information to attempt variations across platforms. Your data can be exploited long after the original breach occured as it travels through criminal networks and gets recombined with other datasets.

How hulk_logs-Style Stealer Log Channels Operate

The hulk_logs designation refers to a Telegram channel used to distribute stealer log output. Operators of these channels aggregate log files from stealer malware infections across hundreds or thousands of devices, then package them by volume and release them to Telegram subscribers. The malware itself captures credentials silently from browsers, email clients, and applications on infected devices, bundling everything into structured log files that include the URL, username, and plaintext password for every saved credential. The 800 LOGS label indicates the number of individual infected machine logs included in this specific package, with each machine contributing multiple credential records to reach the total of 9,519. HEROIC monitors these Telegram channels specifically to identify new releases and definately catalog them before the data causes further harm.
