Researchers Identify PRIVATE LOGS_CENTEER Dump Exposing 13,842 Stolen Credentials on Telegram

In August 2022, HEROIC researchers found a stealer log file posted to a public Telegram channel by an anonymous user. The file, labeled 8.8 PRIVATE LOGS_CENTEER, contained 13,842 records drawn from compromised endpoints. Each record bundled together an email address, a plaintext password, and the URL where those credentials were used, leaving victims fully exposed with no encryption to slow attackers down.

Why This Data Is Dangerous

When a stealer log includes plaintext passwords alongside the exact website URLs, it essentially hands attackers a ready-to-use login kit. There is no decryption needed and no guesswork involved. Anyone who downloaded this file from Telegram could immediately attempt to log into the accounts listed. With email addresses and passwords in the same record, the risk of account takeover is direct and immediate for every person in the dataset.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• Associated URLs

Why This Matters to You

Data from stealer logs does not disappear after one upload. It spreads. Threat actors download these files and feed them into credential stuffing tools that systematicaly test stolen logins across hundreds of popular websites. Even people who changed their passwords on one platform may still be at risk on others where they reused the same credentials. Finantial fraud and identity theft are frequent outcomes when this type of data lands in the hands of organized criminal groups.

How Stealer Logs Work

Stealer malware infects a device quietly, usually delivered through a phishing email or a malicious file download. Once active, it scans the device for saved passwords, browser cookies, and stored login information. It collects everything it can find and sends it back to whoever deployed the malware in an organized log file. That file then gets sold privately or posted publicly on Telegram channels where other criminals can download and use it. The original victim rarely knows anything happened until accounts start showing unauthorised activity.
