Search Your Email: The OnlyLogs – OnlyLogsCloud Dump Exposed 6,663 Accounts

In April 2026, a threat actor operating on Telegram uploaded a stealer log file publicly known as the OnlyLogs - OnlyLogsCloud dump. The file exposed 6,663 records containing email addresses, plaintext passwords, and URLs harvested from infected devices. Stealer logs like this one are particularly dangerouss because they capture credentials at the moment of entry, bypassing even encrypted password managers. If your email appears in this dataset, your accounts may already be under attack.

Why This Is Dangerous

Unlike traditional database breaches, stealer log files capture credentials in real time from compromised devices. Every record in this dump represents an actual login session that was silently recorded by malware. Attackers use these logs to conduct automated credential stuffing attacks across hundreds of popular websites simultaneously. Because the passwords are stored in plaintext, there is no cracking required and your accounts can be accessed imediately after the file is distributed. The OnlyLogs - OnlyLogsCloud dump was uploaded to Telegram, a platform with millions of users and minimal content moderation, meaning the data has likely already spread to numerus threat actor communities.

What Was Exposed

• Email Addresses - Full email addresses tied to the compromised sessions, usable for phishing and account takeover attempts
• Plaintext Passwords - Unencrypted passwords captured directly from browser sessions or application memory
• URLs - The specific websites and services where credentials were stolen, giving attackers a precise roadmap to your accounts

Why This Matters

Stealer log datasets are among the most actionable forms of stolen data in the cybercriminal ecosystem. Unlike older breach datasets that may contain hashed or outdated passwords, this dump contains credentials that were current and active at the time of capture. The combination of email addresses, plaintext passwords, and target URLs means an attacker has everything needed to log into your accounts without any additional steps. Even if you have since changed your passwords, the URLs in the log reveal which services you use, enabling highly targeted phishing campaigns designed specifically for you.

How Stealer Log Breaches Work

Stealer logs originate from infostealer malware infections, a category of malicious software designed to silently harvest credentials from compromised devices. Victims typically encounter infostealers through malicious email attachments, fake software downloads, or compromised websites. Once installed, the malware scans browser saved passwords, active login sessions, clipboard contents, and application credentials before packaging everything into a structured log file. That file is then transmitted back to the attacker or uploaded directly to platforms like Telegram where it can be purchased or shared freely. The OnlyLogs - OnlyLogsCloud dump follows this exact pattern, with a Telegram user acting as the distributor of the harvested data.
