Telegram Folders Leak: 10,055 Records, Like a Small Town

HEROIC analysts identified a stealer log dump, labeled simply "folders," uploaded to Telegram by an anonymous user on April 26, 2024. The file contains 10,055 records pulled from malware-infected devices, including email addresses, plaintext passwords, and the URLs those credentials belong to.

Why This Folders Stealer Log Is Dangerous

What makes this leak especially risky is the pairing of data. Each record doesn't just list an email and password, it lists the exact website or service that login opens. Anyone who gets this file can skip straight to testing real accounts instead of guessing, and because the passwords are stored in plaintext, there's no encryption standing between the attacker and your account.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linked to each set of credentials

Why This Matters

With 10,055 plaintext email and password pairs already matched to specific websites, the biggest danger is direct account takeover. Attackers don't need to crack anything, they can simply log in. And if any of these people reused the same password on other accounts, credential stuffing attacks can spread the damage well beyond the original site.

How Stealer Logs Work

Stealer logs are produced by malware that infects a device and quietly harvests everything saved in the browser: usernames, passwords, and the sites they belong to. That stolen data gets bundled into a file, often just labeled with a generic name like "folders," and shared or sold on Telegram channels and dark web marketplaces for other criminals to exploit.
