The KeyCloud_Free_logs118 Dump Contains Exactly 15,654 Login Pairs

HEROIC analysts identified a stealer log file uploaded to a public Telegram channel on May 26, 2025, labeled Upload by LOGSYNC, KeyCloud_Free_logs118. The file contained exactly 15,654 records made up of email addresses, plaintext passwords, and the URLs of the login pages those credentials belong to.

Why This Dump Is Dangerous

Because the passwords in this file are stored in plaintext and matched directly to a URL, an attacker does not need to guess, crack, or decrypt anything. They can go straight to the exact login page listed for each account and attempt to sign in immediately, giving them everything needed to take over the account without any extra work.

What Was Exposed in the KeyCloud_Free_logs118 Upload

• Email addresses
• Plaintext passwords
• URLs of the affected login pages

Why This Matters for the 15,654 People Affected

A leak of this size gives attackers a large pool of working credentials to run through credential stuffing tools, automatically testing each email and password pair against other websites. Anyone in this file who reused a password elsewhere faces a real risk of account takeover, financial fraud, and identity theft.

How a Stealer Log Like This One Gets Made

Stealer logs are produced by malware that infects a device through a fake download, cracked software, or a phishing link, then quietly copies the passwords and site data saved in the victim's browser. That harvested information is bundled into a log file and shared or sold, often through Telegram accounts like the one behind this LOGSYNC upload. Because the data comes directly from an active browser, the passwords collected are typically the exact ones the victim was using at the time of infection.

Check If You Are Affected

If you want to know whether your email or passwords have surfaced in a stealer log like this one, HEROIC's free breach scanner checks your information against a database of more than 400 billion leaked records. A scan takes seconds and shows you exactly where your data has appeared so you can change any exposed or reused passwords right away.
