Infected in Minutes, Posted in March: The 158 Telegram Log Hit 2,950 Records

HEROIC analysts traced a stealer log posted to Telegram on March 6, 2023, recorded as "158 uploaded by a Telegram User." The file contained 2,950 records scraped from infected endpoints, with email addresses, plaintext passwords, and the URLs each credential unlocks. The timeline from initial malware infection to a public Telegram drop was likely measured in days or even hours, not months.

Why the 158 Telegram Stealer Log Is Dangerous

Unlike database breaches where hashed passwords can stall attackers, every credential in this log is cleartext and already paired with its login URL. That makes the window between leak and account takeover dangerously short. Once a buyer opens the file, they can authenticate against real accounts in seconds.

What Was Exposed in the 158 Telegram Log

• Email addresses used as login identifiers
• Plaintext passwords harvested from browser vaults
• URLs mapping every password to its target site

Why This Matters for the 2,950 Affected Users

The clock on a stealer log starts ticking the moment it is shared. Credential stuffing scripts hit thousands of sites at once, and attackers use the exposed URL column to prioritize banking, email, and cloud accounts first. Identity theft, fraudulent transactions, and takeover of secondary accounts through password resets tend to follow within days.

How a Stealer Log Like the 158 Dump Works

Infostealer families such as RedLine, Raccoon, and Vidar reach victims through cracked downloads, fake installers, and malicious browser extensions. After execution, they scrape browser-saved credentials, cookies, autofill fields, and cryptocurrency wallet files, then send the bundle to their operator. Operators repackage the haul into batch logs and post to Telegram channels where buyers purchase them cheaply, which is how this file ended up public.
