5,829 Stolen Credentails from Telegram Stealer Log

Researchers tracking stealer log activity on Telegram identified a file in August 2023 containing 5,829 stolen credential records, each tied to real email accounts, readable passwords, and specific website URLs. The upload, attributed to an anonymous Telegram user, represents a significant collection of device-harvested data circulating in spaces where cybercriminals trade and share stolen information. The scale of this particular log, nearly 6,000 complete credential sets, makes it a substantial resource for anyone looking to conduct account takeover attacks at volume.

Why This Is Dangerous

At 5,829 records, this file gives an attacker a ready-made attack list requiring no additional processing. Each entry points directly to a specific user on a specific platform with their exact password. Criminals who obtain stealer logs at this scale typically run them through automated tools that attempt logins across dozens of services simultaneously. Successful logins are then either used directly for financial gain or sold as verified account access to other criminal actors. The presence of URLs in this dataset narrows the target list, making attacks faster and success rates higher compared to generic credential lists.

What Was Exposed

• Email addresses
• Plaintext passwords (unencrypted, human-readable, no cracking required)
• URLs (showing precisely which service each credential belongs to)

Why This Matters

A dataset of nearly 6,000 matched credentials circulating through Telegram channels does not stay contained. These files are routinely copied, traded, and merged with other stolen datasets. Victims whose data appears here face risks that extend beyond the single account the credential originally belonged to. Password reuse, which studies consistently show affects the majority of internet users, means that one exposed record can give attackers access to banking apps, email accounts, healthcare portals, and workplace systems. Once a criminal gains access to an email account, they can trigger password resets on any other service linked to that address, compounding the damage from a single stolen record into a full identity compromise.

How Stealer Logs Work

Researchers who analyze stealer logs consistently find that the malware responsible operates in a specific, methodical way. After initial infection, typically through a phishing link, a fake cracked application, or a malicious browser extension, the infostealer runs quietly in the background. It targets the browser's local credential store, which holds usernames and passwords saved during previous browsing sessions. The malware decrypts this store using the same system permissions as the infected user, then reads and records every entry along with the associated URL. In parallel, it harvests active session cookies, which represent authenticated sessions that can be replayed by the attacker without ever needing the password. All of this data is formatted into a structured log and transmitted to the attacker via a command-and-control server or posted directly to a Telegram channel for distribution.

Check If You Are Affected

HEROIC's free breach scanner indexes more than 400 billion records from known breaches, stealer logs, and underground data markets, including Telegram-sourced files like this one from August 2023. Searching your email address takes seconds and will immediately show whether your credentials appear in this dataset or in any of thousands of other known leaks. If your data is found, HEROIC provides clear guidance on which accounts to prioritize and what steps to take next.
