2,528 Records in 133 Telegram Stealer Log Exposed

HEROIC threat researchers have identified 2,528 records from the breach known as 133 uploaded by a Telegram User, a stealer log first surfaced on March 6, 2023. The exposed data set includes email addresses, plaintext passwords, and URLs captured directly from infected devices and posted inside a Telegram channel used by cybercriminals to trade stolen credentials.

Why This Stealer Log Is Dangerous

Stealer logs are fundamentally different from ordinary database leaks. Instead of hashed passwords pulled from one company's servers, the 133 log contains live login pairs harvested by malware running on real user machnes. Every record is a working key to whatever account the victim was logged into at the moment of infection. Because the passwords are in plaintext, no cracking step is required before criminals can act.

What Was Exposed in the 133 Telegram Stealer Log

• Email addresses tied to active online accounts
• Plaintext passwords captured by infostealer malware
• URLs of the login pages where the credentials were used
• Endpoint and API host details revealing victim systems

Why This Matters for Affected Users

With 2,528 verified plaintext credentials in circulation, attackers can imediately attempt credential stuffing across banking portals, email services, corporate SaaS dashboards, and cryptocurrency exchanges. Each URL in the dump tells the attacker exactly which site the password unlocks, which removes the guesswork from account takeover and accelerates identity theft, wire fraud, and lateral movement into workplace accounts.

How a Stealer Log Like the 133 Dump Works

Infostealer malware such as RedLine, Raccoon, and Vidar quietly installs on a victim's device, usually through a malicious download or cracked software. The malware scrapes saved browser passwords, session cookies, autofill data, and crypto wallet files, then uploads everything to an operator. Operators package that harvest into logs and post them in Telegram channels like the one that distributed this 133 record dump, where other criminals buy or download them in bulk.
