The BananaLogs 519count Telegram Leak Contains More Stolen Passwords Than a Small City Has Residents

HEROIC analysts identified a stealer log file uploaded to Telegram on November 7, 2023, exposing 7,512 records tied to BananaLogs 519count uploaded by a Telegram User. The log was discovered inside a Telegram channel used by threat actors to distribute stolen credential sets. The exposed data included plaintext passwords, email addresses, and URLs from a variety of compromised endpoints and API hosts. The structured naming convention of the file suggests this was a deliberate, focused collection effort rather than a broad indiscriminate sweep of infected machines.

Why This BananaLogs Leak Is Dangerous

Stealer logs are among the most immediately usable data types traded on cybercriminal platforms. Unlike hashed password databases that require cracking, stealer logs deliver credentials in plaintext, ready for direct use. Attackers who recieve this data can begin credential stuffing attacks within minutes, targeting email providers, banking apps, and social media platforms where victims likely reuse the same passwords. The presence of API host URLs in the BananaLogs 519count file adds another layer of risk, as these can point attackers directly toward backend systems and developer accounts.

What Was Exposed

The BananaLogs 519count stealer log contained the following catagories of personal and account data:

• Email Addresses
• Plaintext Passwords
• URLs

Why This Matters

With 7,512 records exposed, this leak represents thousands of real people whose credentials were silently harvested from their own devices without any knowledge. Even if the affected service is relatively obscure, the passwords and email combinations in this log are tested against dozens of other platforms in automated credential stuffing campaigns. The fact that these records were uploaded to Telegram means they were accessable to a large audience of cybercriminals, multiplying the number of potential attackers who could act on the data. Credential stuffing tools can test thousands of combinations per second, so every record in this log represents a real risk to every account where that password was reused.

How Stealer Logs Work

Stealer logs are produced by information-stealing malware that typically infects devices through phishing emails, fake software downloads, or malicious browser extensions. Once installed, the malware silently extracts saved passwords from browsers, active session tokens, autofill data, and URLs of recently visited sites. All of this is packaged into a structured log file and transmited back to the attacker's server. The attacker then organizes the logs by service type or geography and uploads batches to Telegram channels, where other criminals can download or purchase them. The BananaLogs naming convention suggests this batch was sorted and labeled for easy distribution.

Check If You Are Affected

If your email address or passwords appeared in the BananaLogs 519count Telegram stealer log, you may not know until an attacker has already used your credentials. HEROIC offers a free personal data scanner that checks your email against more than 400 billion records from data breaches and stealer logs across the dark web. Run a free scan now to see whether your information was captured in this leak or any other known breach. If your credentials are found, update your passwords immediately and enable two-factor authentication on every account that supports it.
