Telegram Stealer Dump: 9,767 Passwords Exposed. Yours Might Be One.

In May 2023, a threat actor uploaded a stealer log file to Telegram that exposed 9,767 records containing plaintext passwords, email addresses, and endpoint URLs harvested directly from infected computers. This is not a breach of a company's database. The data was stolen from individual people's devices, while they were using them, by malware running silently in the background. By the time this file surfaced publicly, the credentials it contained had likeldy already been tested, traded, and used in account takeover attacks. If your email is in this dump, your password is already in the hands of criminals.

Why This Is Dangerous

There is no safe version of appearing in a stealer log. Every password in this 9,767-record dump is in plaintext -- no hashing, no encoding, no barrier between the leaked file and a working login attempt. Attackers do not need to crack anything. They download the file, import the credentials into an automated tool, and begin testing them against Gmail, Outlook, banking apps, and corporate login pages within minutes. The URLs included in this dump make it even worse: they tell attackers exactly which sites the victim was using, turning a generic credential list into a precisely targeted attack map. For each person in this dump, the attacker already knows where to try the password first.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (endpoint and API host addresses)

Why This Matters

9,767 records is not a small number. And this file is not an isolated incident -- it is part 60 of an ongoing stealer log series, meaning the same operation produced at least 59 other dumps before this one. Each part represents a separate batch of compromised devices and stolen credentials. The cumulative exposure across the entire series likely numbers in the hundreds of thousands of records. People who appear in any part of this collection should assume their password is already being used in automated attack campaigns, regardless of how long ago they believe they last updated it. Password reuse is the multiplier that turns a single stolen credential into access to a dozen different accounts.

How Stealer Logs Work

Stealer malware reaches victims through everyday vectors: a malicious email atachment that looks like an invoice, a pirated software download, a fake browser extension offering a useful feature. Once the malware is installed, it runs invisibly. It reads the saved password database from Chrome, Firefox, and Edge, captures cookies that keep the victim logged into sites, and records credentials typed into login forms. Everything collected is packaged into a log file and automaticaly transmitted to the attacker. The victim sees nothing. There is no popup, no warning, no slowdown that would indicate anything unusual is happening. The first sign many victims have that something went wrong is discovering their accounts have been accessed by someone else.
