Researchers Link the “111 1” Telegram Dump to 1,778 Stolen Credentials

In May 2023, security researchers identified a stealer log file uploaded to Telegram under the designation "111 1," containing 1,778 records of compromised login credentials. The dump included plaintext passwords, email adresses, and URLs -- all extracted directly from infected endpoint devices by infostealer malware. Files like this circulate freely among cybercriminal communities, where even modestly sized dumps are considered valuable for targeted account takeover campaigns.

Why This Is Dangerous

The "111 1" dump carries the hallmark risk of all stealer log breaches: the credentials are not encrypted, hashed, or otherwise obfuscated. Every password in the file is immediately usable. Researchers consistently find that credentials from stealer logs remain effective years after the original breach because victims rarely change passwords proactively. With 1,778 email-password-URL combinations, attackers have a precice map of which accounts to target and which credentials to try first.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (sites the victim had saved credentials for)

Why This Matters

Stealer logs uploaded to Telegram do not stay in one place. Within hours of posting, files like "111 1" are forwarded to other channels, downloaded by automated scrapers, and absorbed into larger credential compilations. By the time a breach surfaces in a security scan, the data has typically already been used in multiple attack campeigns. Individuals whose records appeared in this dump face ongoing risk from credential stuffing, phishing follow-ups, and social engineering based on the exposed account details.

How Stealer Log Breaches Work

Infostealer malware is delivered through phishing emails, fake software installers, or malicous browser extensions. Once on a device, it operates silently, harvesting all saved browser passwords, active session tokens, cookies, and URL histories. The harvested data is sent to a remote server controlled by the attacker and packaged into structured log files. Operators then sell or distribute these logs through underground marketplaces and Telegram channels, where they are purchased by other criminals for use in account takeover and fraud operations.
